Recently, many studies have shown that celecoxib induces apoptosis in various cancer cells by different mechanisms depending on the cell type. This study examined the effect of the selective COX-2 inhibitor celecoxib on cisplatin and TNF-α cytotoxicity and studied the role of mitochondria in the induction of apoptosis in the human cervical carcinoma SiHa cells. Apoptosis was detected by flow cy...

Infection of macrophages with bacteria induces the production of pro-inflammatory cytokines including TNF-α. TNF-α directly stimulates osteoclast differentiation from bone marrow macrophages in vitro as well as indirectly via osteoblasts. Recently, it was reported that bacterial components such as LPS inhibited RANKL-induced osteoclastogenesis in early stages, but promoted osteoclast differenti...

PURPOSE To determine if a serine protease inhibitor A3K (SA3K) reduces TNF-α-induced declines in rabbit corneal endothelial junctional barrier integrity. METHODS New Zealand rabbit corneas were incubated ex vivo for 24 hours in Dulbecco's modified Eagle's medium (DMEM) containing 10% FBS with or without TNF-α, in the presence or absence of SA3K at different concentrations. Corneal endothelial...

Background & Aim: Incremental increase in the risk of serious infections with combinations of tumor necrosis factor-alpha (TNF-α) inhibitors and immunomodulators compared to monotherapy with these agents in in ammatory bowel disease (IBD) is unclear. Our aim was to analyze whether there is such an incremental increase in the odds of serious infections. Methods: e FDA Adverse Event Reporting Sys...

A large body of evidence has indicated that induction of endogenous antioxidative proteins seems to be a reasonable strategy for delaying the progression of cell injury. In our previous study, cilostazol was found to increase the expression of the antioxidant enzyme heme oxygenase-1 (HO-1) in synovial cells. Thus, the present study was undertaken to examine whether cilostazol is able to counter...

Critical vascular inflammation leads to vascular dysfunction and cardiovascular diseases, including abdominal aortic aneurysms, hypertension, and atherosclerosis. Andrographolide is the most active and critical constituent isolated from the leaves of Andrographis paniculata, a herbal medicine widely used for treating anti-inflammation in Asia. In this study, we investigated the mechanisms of th...

Tumor necrosis factor α (TNF-α) influences endothelial cell viability by altering the regulatory molecules involved in induction or suppression of apoptosis. However, the underlying mechanisms are still not completely understood. In this study, we demonstrated that A20 (also known as TNFAIP3, tumor necrosis factor α-induced protein 3, and an anti-apoptotic protein) regulates the inhibitor of ap...

Objectives: This experimental study investigated the preventive effects of Celecoxib, a selective COX-2 inhibitor, on lung injury induced by intra-abdominal sepsis in rats. The assessed Celecoxib's potential to mitigate harmful impacts tissue. Methods: Thirty male Wistar albino rats, divided into three groups: normal control group, sepsis-induced group treated with saline, and Celecoxib. Sepsis...

Chlorpyrifos (CP), an acetylcholinesterase (AChE) inhibitor, is used throughout the world as an insecticide in agriculture and an eradicating agent for termites around homes. In this present study, CP is considered as an oxidative agent which we examine the protective role of zinc oxide nanoparticles (ZnO NPs) in CP-treated lymphocytes of human. Lymphocytes isolated by Ficoll and exposed to 75 ...

AIMS Genistein, an isoflavone derivative found in soy, is known as a promising treatment for rheumatoid arthritis (RA). However, the detailed molecular mechanism of genistein in suppression of proinflammatory cytokine production remains ambiguous. The aim of this work was to evaluate the signal pathway by which genistein modulates inflammatory cytokine expression. MATERIALS AND METHODS MH7A c...
