Oxidative stress is known to be involved in a variety of pathological processes including atherosclerosis, diabetes, and neurodegenerative diseases. Understanding how intracellular signaling pathways respond to oxidative stress will have a significant implication in the therapy of these diseases. In this study, we applied hydrogen peroxide (H(2)O(2)) to trigger apoptosis and investigated the dy...

Objective(s): The useful and effective role of exercise program to prevent cardiac tissue apoptosis and fibrosis in ovariectomized type 2 diabetic (T2DM) rats (OVR.D) is well known. The current study aimed to investigate the simultaneous effects of T2DM and swimming plan on the expression of some apoptotic, anti-apoptotic biomarkers and glycogen changes in the cardiac ...

To investigate the effect and related mechanism of propofol anesthesia on pyroptosis in neonatal rat hippocampus. Neonatal rats were divided into a control group (injected intraperitoneally with saline), 80 mg/kg propofol) propofol+MCC950 10 MCC950) administered for 5 d. The day after end drug administration, hippocampi analyzed by transferase dUTP nick labeling assay interleukin beta-1, interl...

Background: The aim of the study was to determine mechanism Moringa oleifera-induced apoptosis in HeLa cells. cells over-express cyclin E and B1, abrogate G0-G1 G2-M cell cycle arrest, promoting tumorigenesis. Cyclin E, E2F1 telomerase expression, caspase-3 -7 activation were assessed after 24-treatment with M. oleifera leaf fractions. Material methods: Apoptosis through caspase-7 determined qu...

A number of 1,2-benzisothiazol-3-one derivatives were prepared through structural modification of the original compound from high-throughput screening. Some analogues (e.g., 6b, 6r, 6s and 6w) were identified as novel and potent caspase inhibitors with IC50 of nanomolar. Structure-activity relationship (SAR) studies for caspase-3 inhibition were evaluated in vitro. Molecular modeling studies pr...

Evaluating the impact of Viola spathulata in a rat model brain ischemia/reperfusion by influencing expression level caspase-3 and cyclooxygenase-2

Buccal mucosa squamous cell carcinoma (BMSCC) is the most common oral cancer in Southeast Asia. Caspase-3, a key molecule in regulating apoptosis, promotes the malignancy of various cancers. However, its role in BMSCC is unknown. Herein, we evaluated the association of caspase-3 expression with tumorigenesis and prognosis in BMSCC patients. Immunohistochemical staining indicated that the expres...

Caspase-3 was cloned from zebrafish embryos and its properties were characterized to identify the biological implications of caspase in embryogenesis and apoptosis in zebrafish, which is a model organism in vertebrate developmental biology and genetics. The predicted amino acid sequence, totalling 282 amino acid residues, consisted of the prodomain and large and small subunits. Phylogenetic ana...

Members of the caspase family are essential for many apoptotic programs. We studied mouse embryonic fibroblasts (MEFs) deficient in caspases 3 and 7 and in caspase 9 to determine the role of these proteases in endoplasmic reticulum (ER) stress-induced apoptosis. Both caspase 3(-/-)/caspase 7(-/-) and caspase 9(-/-) MEFs were resistant to cytotoxicity induced via ER stress and failed to exhibit ...
