Ten male albino guinea pigs (300-350 g in weight) were randomly allocated into two groups: the primal group was exposed to 4- kHz octave band noise at 102 dB SPL for 3 hrs (group 1, n=5); the latter pretreated with 50 mg/ kg celecoxib for 3 days, then exposed to noise (group 2, n=5). Before exposure and one hr after noise exposure, threshold shifts were evaluated with auditory brainstem responses (ABR) and finally the animals were euthanized for histological evaluation.

We report a sulfonamide/sulfamate inhibition study of the α-carbonic anhydrase (CA, EC 4.2.1.1) present in the gammaproteobacterium Thiomicrospira crunogena XCL-2, a mesophilic hydrothermal vent-isolate organism, TcruCA. As Thiomicrospira crunogena is one of thousands of marine organisms that uses CA for metabolic regulation, the effect of sulfonamide inhibition has been considered. Sulfonamide-based drugs have been widely used in a variety of antibiotics, and bioelimination of these compounds results in exposure of these compounds to marine life. The enzyme was highly inhibited, with Ki values ranging from 2.5 to 40.7nM by a variety of sulfonamides including acetazolamide, methazolamide, ethoxzolamide, dichlorophenamide, dorzolamide, brinzolamide, benzolamide and benzenesulfonamides incorporating 4-hydroxyalkyl moieties. Less effective inhibitors were topiramate, zonisamide, celecoxib, saccharin and hydrochlorothiazide as well as simple benzenesulfonamides incorporating amino, halogeno, alkyl, aminoalkyl and other moieties in the ortho- or para-positions of the aromatic ring (Kis of 202-933nM). The active site interactions between TcruCA and three clinically-used CA inhibitors, acetazolamide (Diamox®), dorzolamide (Trusopt®), and brinzolamide (Azopt®) are studied using molecular docking to provide insight into the reported Ki values. Comparison between various enzymes belonging to this family may also bring interesting hints in these fascinating phenomena.

No direct effects of celecoxib on healthy normal cartilage were found. Both PBMC and IL-1beta plus TNF-alpha induced strong inhibition of cartilage proteoglycan synthesis and significant enhancement of the release of proteoglycans, diminishing proteoglycan content. Celecoxib was able to reverse these adverse effects up to complete normalization.

A retrospective analysis of the Veterans Integrated Service Network 17 Veterans Affairs (VA) database was conducted. Medicare data and Texas Department of Health mortality data were incorporated to capture events occurring outside the VA healthcare network. Patients >or=35 years of age who received celecoxib, rofecoxib, ibuprofen, etodolac and naproxen from 1 January 1999 through 31 December 2001, were included. Multivariate Cox proportional hazard models were used to analyse the relationship between cardiovascular risk and NSAID use, including selective COX-2 inhibitor use, while adjusting for various risk factors.

The inducible COX-2 enzyme is over-expressed in human breast cancer and its over-expression generally correlates with angiogenesis, deregulation of apoptosis and worse prognosis. This observation may explain the beneficial effect of nonsteroidal anti-inflammatory drugs and COX-2 inhibitors on breast cancer treatment. Here, we evaluated the antiproliferative activity of celecoxib, a selective COX-2 inhibitor, and its nitro-oxy derivative on human breast cancer cells characterized by low and high COX-2 expression, respectively. In ERα(+) MCF-7 cells celecoxib and its derivative induce a strong inhibition of cell growth, inhibition that is associated with the reduction of ERα expression and activation. These effects may be directly associated with ERK and Akt suppression and with PP2A and PTEN induction. In this cell line the drugs exert only weak effect on COX-2 level while they are able to reduce aromatase expression. On the contrary, in ERα(-) MDA-MB-231 cells, both drugs induce a marked inhibition of COX-2, inhibition that is associated with the reduction of aromatase expression and of cell proliferation. In both cell lines the effects of the drugs are associated with the suppression of cell invasion.

IL-1alpha transgenic (Tg) mice exhibit chronic inflammatory arthritis and subsequent osteopenia, with IL-1-induced GM-CSF playing an important role in the pathogenesis. This study analyzed the mechanisms underlying osteopenia in Tg mice, and the therapeutic effects of the cyclooxygenase-2 inhibitor celecoxib on such osteopenia. Inhibited osteoclast formation was observed in RANKL-treated bone marrow cell (BMC) cultures from Tg mice and coculture of Tg-derived BMCs and wild-type-derived primary osteoblasts (POBs). FACS analysis indicated that this inhibition was attributable to a decreased number of osteoclast precursors within Tg-derived BMCs. Moreover, in coculture of Tg-derived POBs and either Tg- or wild-type-derived BMCs, osteoclast formation was markedly inhibited because Tg-derived POBs produced abundant GM-CSF, known as a potent inhibitor of osteoclast differentiation. Histomorphometric analysis of Tg mice revealed that both bone formation and resorption were decreased, with bone formation decreased more prominently. Interestingly, administration of celecoxib resulted in further deterioration of osteopenia where bone formation was markedly suppressed, whereas bone resorption remained unchanged. These results were explained by our in vitro observation that celecoxib dose-dependently and dramatically decreased osteogenesis by Tg mouse-derived POBs in culture, whereas mRNA expressions of GM-CSF and M-CSF remained unchanged. Consequently, blockade of PGE(2) may exert positive effects on excessively enhanced bone resorption observed in inflammatory bone disease, whereas negative effects may occur mainly through reduced bone formation, when bone resorption is constitutively down-regulated as seen in Tg mice.

Celecoxib concentrations trended higher in women taking 400 mg (median 1025.0 ng/mL) compared to 200 mg bid (median 227.3 ng/mL), and in post- (534.6 ng/mL) compared to premenopausal (227.3 ng/mL) women. In postmenopausal women treated with the higher (400 mg bid) celecoxib dose, uPA concentrations increased, while PAI-1 and PGE2 decreased. In women taking the higher dose, both PAI-1 (r = -.97, p = .0048) and PGE2 (r = -.69, p = .019) in NAF and uPA in plasma (r = .45, p = .023) were correlated with celecoxib concentrations.

The current in vitro study indicates that inhibition of proliferation and induction of apoptosis in human cholangiocarcinoma cells by cyclooxygenase-2 specific inhibitor celecoxib may involve in COX-dependent mechanisms and PGE(2) pathway. Celecoxib as a chemopreventive and chemotherapeutic agent might be effective primarily on COX-2-expressing cholangiocarcinoma.

The present study evaluated the involvement of interleukin(IL)-1β, tumor necrosis factor-α (TNF-α), IL-6, interferon(IFN)-γ, prostaglandins of the E2 series, endothelins, substance P and opioids within the central nervous system in polyinosinic:polycytidylic acid (Poly I:C)-induced fever in rats. Poly I:C injection induced a febrile response which was reduced by intracerebroventricular administration of the antibodies against TNF-α, IL-6, or IFN-γ, or by IL-1 or μ receptor antagonists. Intraperitoneal injection of indomethacin or oral administration of celecoxib also reduced Poly I:C-induced fever. Poly I:C increased prostaglandin E2 levels in the cerebrospinal fluid of the animals which was also reduced by indomethacin. The intracerebroventricular injection of ETB or NK1 receptor antagonists did not alter Poly I:C-induced fever. These data suggest the involvement of IL-1β, TNF-α, IL-6, IFN-γ, prostaglandin E2, and opioids but not endothelins and substance P on Poly I:C-induced fever.

Stable hypertensive patients without a history of heart failure and newly treated with celecoxib, rofecoxib, ibuprofen, naproxen, or diclofenac between January 1, 1999, and September 30, 2000, were identified from the LifeLink Integrated Claims Solutions employer database. The incidence rate of inpatient and outpatient heart failure claims was determined based on patients' time of exposure to study drugs after adjusting for confounding factors. The heart failure costs of managing inpatient and outpatient events were estimated as the total healthcare costs for patients with heart failure claims minus the total healthcare costs among matched control groups without heart failure claims. Healthcare costs were computed for the 0 to 30 days and 31 to 90 days following the initial outpatient or inpatient claim. Finally, the excess incidence rate of patients with inpatient and outpatient heart failure claims, relative to celecoxib, were multiplied by the heart failure cost of an inpatient and outpatient event to determine the incremental costs of heart failure associated with each of the study drugs relative to celecoxib.

Prostaglandin E2 (PGE2) is well known as a mediator of inflammatory symptoms such as fever, arthritis, and inflammatory pain. In the present study, we evaluated the analgesic effect of our selective PGE2 synthesis inhibitor, compound I, 2-methyl-2-[cis-4-([1-(6-methyl-3-phenylquinolin-2-yl)piperidin-4-yl]carbonyl amino)cyclohexyl] propanoic acid, in rat yeast-induced acute and adjuvant-induced chronic inflammatory pain models. Although this compound suppressed the synthesis of PGE2 selectively, no analgesic effect was shown in both inflammatory pain models. Prostacyclin (PGI2) also plays crucial roles in inflammatory pain, so we evaluated the involvement of PGI2 signaling in rat inflammatory pain models using prostacyclin receptor (IP) antagonist, RO3244019. RO3244019 showed no analgesic effect in inflammatory pain models, but concomitant administration of compound I and RO3244019 showed analgesic effects comparable to celecoxib, a specific cyclooxygenase- (COX-) 2 inhibitor. Furthermore, coadministration of PGE2 receptor 4 (EP4) antagonist, CJ-023423, and RO3244019 also showed an analgesic effect. These findings suggest that both PGE2 signaling, especially through the EP4 receptor, and PGI2 signaling play critical roles in inflammatory pain and concurrent inhibition of both signals is important for suppression of inflammatory hyperalgesia.

Recurrent laryngeal papillomatosis (RRP) can be a devastating condition for a child to endure, and pulmonary involvement may have terminal consequences. Adjuvant therapies have been trialed and reported over the years; however, these chemotherapy options have not been successful. Bevacizumab (Avastin, Genetech Inc., South San Francisco, CA) is a vascular endothelial factor (VEGF) inhibitor that has shown promise in the management of papillomatosis. Most research has focused on intralesional injections of this antiangiogenic drug. The systemic use of bevacizumab is not as well described. This is a case report of a 12-year-old female diagnosed with severe laryngotracheal papillomatosis near birth who underwent a tracheostomy tube placement at 1 year of age. She required weekly debridements to prevent tracheal obstruction. When lung involvement was diagnosed at 1 year of age, cidofovir was started intravenously. Over the course of the past 10 years, the patient was managed with celecoxib (Celebrex, Pfizer, New York, NY), anti-reflux medications, zithromycin, propranolol, Gardasil (Merck and Co., Kenilworth, NJ), and a 7-year course of interferon-alpha. Intravenous bevacizumab was started when the patient's pulmonary status deteriorated. There was remarkable improvement in her laryngotracheal disease within 6 weeks of therapy. Following 3 months of bevacizumab, the patient's disease was completely resolved at the laryngeal level and nearly gone in the trachea, and she was decannulated. A computed scan was performed following 5 months of intravenous bevacizumab, and the pulmonary RRP nodules completely resolved. The patient had no major or minor complication from the chemotherapy to date. Systemic Bevacizumab is a promising modality of adjuvant therapy for significant papillomatosis. Laryngoscope, 2016.

In a well-defined fast-track setup for total hip and knee arthroplasty, with a multimodal analgesic regimen consisting of intra-operative local anaesthetic infiltration and oral celecoxib, gabapentin and paracetamol for 6 days postoperatively, we conducted a prospective, consecutive, observational study. The purpose was to describe the prevalence and intensity of subacute postoperative pain and opioid related side effects, use of analgesics and functional ability 1-10 and 30 days postoperatively. Fast-track total hip and knee arthroplasty with early discharge (< 3 days) resulted in acceptable levels of pain and postoperative nausea and vomiting with concomitant low use of opioids in > 95% of patients after discharge before day 10 after total hip arthroplasty. However, after total knee arthroplasty 52% patients reported moderate pain (VAS 30-59 mm), and 16% severe pain (VAS > or = 60 mm) when walking 1 month after surgery with a concomitant increase in the use of strong opioids. These results emphasise the need for improvement in analgesia after discharge following total knee arthroplasty, to facilitate rehabilitation.

The η-carbonic anhydrases (CAs, EC 4.2.1.1) were recently discovered as the sixth genetic class of this metalloenzyme superfamily, and are so far known only in protozoa, including various Plasmodium species, the causative agents of malaria. We report here an inhibition study of the η-CA from Plasmodium falciparum (PfCA) against a panel of sulfonamides and one sulfamate compound, some of which are clinically used. The strongest inhibitors identified were ethoxzolamide and sulthiame, with KIs of 131-132 nM, followed by acetazolamide, methazolamide and hydrochlorothiazide (KIs of 153-198 nM). Brinzolamide, topiramate, zonisamide, indisulam, valdecoxib and celecoxib also showed significant inhibitory action against PfCA, with KIs ranging from 217 to 308 nM. An interesting observation was that the more efficient PfCA inhibitors are representative of several scaffolds and chemical classes, including benzene sulfonamides, monocyclic/bicyclic heterocyclic sulfonamides and compounds with a more complex scaffold (i.e., the sugar sulfamate derivative, topiramate, and the coxibs, celecoxib and valdecoxib). A comprehensive inhibition study of small molecules for η-CAs is needed as a first step towards assessing PfCA as a druggable target. The present work identifies the first known η-CA inhibitors and provides a platform for the development of next generation novel PfCA inhibitors.

Four clinical trials were found: three randomized controlled trials (RCTs) and one open-label extension of a previous RCT. All RCTs showed a good safety profile for celecoxib treatment in AS, similar to that of nonselective NSAIDs. However, long-term (>or= 1 year) celecoxib safety in AS was not investigated in RCTs. buy celebrex Based on the results of long-term non-AS celecoxib studies, most of the AS patients (because of young age and fewer comorbidities) are probably at low risk for cardiovascular and gastrointestinal complications. Celecoxib showed a good efficacy and safety profile in AS, but further investigations are needed to clarify the long-term safety of celecoxib in this group of patients.

The investigation of the effects of the celecoxib as a cylooxygenase-2 (COX-2) inhibitor on the course of the acute necrotising pancreatitis (ANP) in rats. ANP was induced in 72 rats by standardized intraductal glycodeoxycholic acid infusion and intravenous cerulein infusion. The rats were divided into four groups (six rats in each group): Sham + saline, sham + celecoxib, ANP + saline, ANP + celecoxib. Six hours later after the ANP induction, celecoxib (10 mg/kg) or saline was given i.p. In the 12th hour, routine cardiorespiratuar, renal parameters were monitored to assess the organ function. The serum amylase, alanine amino transferase (ALT), interleukin 6 (IL-6), lactate dehydrogenase (LDH) in bronchoalveolar lavage (BAL) fluid, the serum concentration of the urea, the tissue activity of myeloperoxidase (MPO) and malondialdehyde (MDA) in pancreas and lungs were measured. The pancreas histology was examined. In the second part of the study, 48 rats were studied in four groups similar to the first part. Survival of all the rats after the induction of ANP was observed for 24 h. The induction of the pancreatitis increased the mortality from 0/12, in the sham groups to 4/12 (30%) in the acute pancreatitis with saline group, 5/12 (42%) in the acute pancreatitis with celecoxib group respectively, heart rate, the serum activities of amylase, ALT, the tissue activities of MPO, MDA in the pancreas and lung, and LDH in BAL fluid, the buy celebrex serum concentration of the urea and IL-6, the degree of the pancreatic damage and decreased the blood pressure, the urine production, pO(2) and the serum concentration of calcium. The use of celecoxib did not alter these changes except the serum IL-6 concentration, urine production and MPO, MDA activities in the tissue of the lungs and pancreas. Serum urea concentration and pancreatic damage in ANP + celecoxib group were insignificantly lesser than ANP + saline group. Whereas treatment with celecoxib improves lung and renal functions, the degree of pancreatic damage partially and the serum IL-6 level completely, it does not improve the cardiovascular and liver functions, the mortality rate and the calcium level. Celecoxib may be useful for the support of some organ functions during ANP in rats.

Hypertension is associated with endothelial dysfunction that is attributable to oxidative stress and a proinflammatory state. Under these conditions, enhanced expression of cyclooxygenase-2 might lead to increased production of vasoconstrictor prostanoids and reactive oxygen species that reduce the bioavailability of endothelium-derived nitric oxide. To investigate the contribution of cyclooxygenase-2 activity to endothelial dysfunction in human hypertension, we evaluated brachial artery vasodilator function by ultrasound in 29 hypertensive patients before and after treatment with the selective cyclooxygenase-2 inhibitor celecoxib or placebo in a randomized, double-blind study. Brachial artery flow-mediated dilation improved from a baseline of 7.9+/-4.5% to 9.9+/-5.1% (P=0.005) 3 hours after the first dose and to 10.1+/-6.1% (P=0.006) after 1 week of treatment with celecoxib. In contrast, placebo treatment had no significant effect on flow-mediated dilation (8.1+/-4.4%, 8.3+/-3.5%, and 8.0+/-3.2%, respectively). Neither treatment buy celebrex altered nitroglycerin-mediated dilation, extent of reactive hyperemia, or baseline arterial diameter. Celecoxib treatment had no significant effect on the urinary concentrations of F2 isoprostane or thromboxane metabolites. However, urinary concentrations of the prostacyclin metabolite 2,3-dinor-6-ketoprostglandin F1alpha were significantly lower after 1 week of celecoxib treatment. Thus, cyclooxygenase-2 products contribute to endothelial dysfunction in hypertension, and treatment with a cyclooxygenase-2 inhibitor could have a beneficial effect in this setting. However, cyclooxygenase-2 inhibition also has an adverse effect on prostacyclin production that could promote thrombosis, and the net clinical consequences of improved endothelial function versus loss of prostacyclin merits further investigation.

Sixty-three patients were randomized and 47 completed the study. The WOMAC pain subscale was the most responsive of all five pain measures. Pain-activity composites resulted in a statistically significant difference between celecoxib and placebo but were not more responsive than pain measures alone. However, a composite responder defined as having 20% improvement in pain or 10% improvement in activity yielded much larger differences between celecoxib and placebo than with pain scores alone. Actigraphy was more responsive than the WOMAC function scale, possibly due to lower buy celebrex placebo responsiveness.

We herein disclose a series of compounds with potent inhibitory activities towards histone deacetylases (HDAC) and cyclooxygenases (COX). These compounds potently inhibited the growth of cancer cell lines consistent with their anti-COX and anti-HDAC activities. While compound 2b showed comparable level of COX-2 selectivity as celecoxib, compound 11b outperformed indomethacin in terms of selectivity towards COX-2 relative to COX-1. An important observation with our lead compounds (2b, 8, 11b, and 17b) is their enhanced cytotoxicity towards androgen dependent prostate cancer cell line (LNCaP) relative to androgen independent prostate cancer cell line (DU-145). Interestingly, compounds 2b and 17b arrested the cell cycle progression of LNCaP buy celebrex in the S-phase, while compound 8 showed a G0/G1 arrest, similar to SAHA. Relative to SAHA, these compounds displayed tumor-selective cytotoxicity as they have low anti-proliferative activity towards healthy cells (VERO); an attribute that makes them attractive candidates for drug development.

Cells positive for CD133 were isolated from glioblastoma specimens and characterized by flow cytometry, then treated with celecoxib and/or ionizing radiation (IR). Clonogenic assay, cell irradiation, cell cycle analysis, Western blot, and xenotransplantation were used to assess the effects of celecoxib alone, IR alone, and IR with celecoxib on CD133(+) and CD133(-) glioblastoma cells. Three separate xenotransplantation experiments were carried out using 310 severe combined immunodeficient (SCID) mice: 1) an initial tumorigenicity evaluation in which 3 different quantities of untreated CD133(-) cells or untreated or pretreated CD133(+) cells (5 treatment conditions) from 7 different tumors were injected into the striatum of 2 mice (210 mice total); 2) a tumor growth study (50 mice); and 3) a survival study (50 mice). For these last 2 studies the same 5 categories of cells were buy celebrex used as in the tumorigenicity (untreated CD133(-) cells, untreated or pretreated CD133(+) cells, with pretreatment consisting of celecoxib alone, IR alone, or IR and celecoxib), but only 1 cell source (Case 2) and quantity (5 × 10(4) cells) were used.

The cyclooxygenase-2 (COX-2) enzyme is induced upon inflammation and in neoplastic tissues. It produces prostaglandins that stimulate tumor angiogenesis and tumor growth. Therefore, destruction and/or specific inhibition of COX-2 should be an important aspect of future tumor therapy. Recently, clinical application of specific COX-2 inhibitors called coxibs became doubtfully because they produce serious renal and cardiovascular complications under long term application. The exact underlying mechanisms are poorly understood and the different effects of diverse coxibs are not explained. It has been demonstrated before that COX-2 is degraded by the ubiquitin (Ub) proteasome system (UPS). However, how ubiquitination is accomplished and regulated was unclear. An important regulator of the UPS is the COP9 signalosome (CSN), which controls the stability of many proteins. Here we show that the proteasome-dependent degradation of COX-2 in HeLa cell lysate and in HeLa cells was stimulated by curcumin, an inhibitor of CSN-associated kinases. These data suggest a function of the CSN in the degradation of COX-2. In addition, proteolysis of COX-2 was significantly accelerated by parecoxib, but not by celecoxib or rofecoxib. By density gradient centrifugation and immunoprecipitation we demonstrate that COX-2 physically interacts with the CSN. Moreover, COX-2 is associated with large complexes consisting of the CSN, cullin-RING Ub ligases buy celebrex and the 26S proteasome. Pulldown experiments with Flag-COX-2 revealed cullin 1 and cullin 4 as components of the large super-complexes. Cullin 1 and 4 are scaffolding proteins of Ub ligases that presumably ubiquitinate COX-2. Treatment of HeLa cells with parecoxib results in an accelerated degradation of endogenous COX-2 accompanied by an increase of COX-2-Ub conjugates. In HeLa cells parecoxib is converted to the selective COX-2 inhibitor valdecoxib. Addition of valdecoxib also stimulates COX-2 degradation in HeLa cells. We therefore conclude that valdecoxib specifically interacts with COX-2 and induces a conformation accessible for ubiquitination and degradation.

Postmenopausal women with ER-positive DCIS diagnosed by core biopsy were randomized to a 2 x 2 design of either 14 days of exemestane or placebo and celecoxib, or placebo Cytoxan Suspension immediately before surgery. Paired baseline and end point biopsies were analyzed for proliferation (Ki67), apoptosis, human epidermal growth factor receptor 2 (HER2), COX-2, and progesterone receptor (PR) expression by immunohistochemistry. The primary end point was a decrease in Ki67 between diagnosis and surgical excision.

COX-2 over-expression during reflux oesophagitis promotes inflammation of the oesophagus as celecoxib pretreatment significantly reduced tissue damage and MPO activity in rats with reflux oesophagitis (RE-rats). By contrast, dmPGE(2) pretreatment significantly exacerbated tissue injury and simultaneously increased COX-2 expression, PGE(2) levels and MPO activity in RE-rats. Further, melatonin pretreatment significantly reduced the tissue injury, COX-2 over-expression, PGE(2) level and MPO activity in RE-rats Inderal 200 Mg . Melatonin offered more potent suppression of COX-2, PGE(2) and MPO activity than the proton-pump inhibitor omeprazole; however, both reduced the lesion injury to a similar extent. Melatonin at a dose of 20 mg/kg failed to inhibit significantly the dmPGE(2) -induced tissue damage, COX-2 expression, PGE(2) level and MPO activity in RE-rats while at a higher dose of 40 mg/kg it significantly attenuated these changes.

We found 19 eligible studies out of 2,422 reports. Meloxicam demonstrated a low increase in composite risk (OR' 1.14; CI 1.04-1.25) which was mainly vascular in nature (OR' 1.35; CI 1.18-1.55] as it did not elevate myocardial (OR' 1.13; Prilosec Dogs Dose CI 0.98-1.32) or renal (OR', 0.99; CI 0.72-1.35) risks. Relative to meloxicam, other NSAIDs increased the composite risk, in a dose-dependent fashion, in the following order: rofecoxib > indomethacin > diclofenac > celecoxib > naproxen > ibuprofen. OR' was also influenced by type of disease and the comparator used, and acetylsalicylic acid.

Curcumin potentiates the growth inhibitory effect of celecoxib by shifting the dose-response curve to the left. The synergistic growth inhibitory Topamax Highest Dose effect was mediated through a mechanism that probably involves inhibition of the COX-2 pathway and may involve other non-COX-2 pathways. This synergistic effect is clinically important because it can be achieved in the serum of patients receiving standard anti-inflammatory or antineoplastic dosages of celecoxib.

A reduction by 80 and 90% both in the number and size of altered hepatic foci was observed in the group treated with celecoxib during hepatocarcinogenesis treatment, respectively. No evidence of Aldactone 50mg Tablet apoptosis was observed in our present study, however, the expression of the proliferation markers such as PCNA and Ki-67 was drastically reduced. Interestingly, neither COX-2 expression nor prostaglandin-E2 (PGE2) production were altered by the hepatocarcinogenic treatment or celecoxib treatment. Finally, celecoxib inhibited the translocation of Rel A/p65 to the nucleus with significant effect on stability of the repressor IkappaB-alpha.
