Monocrotaline (MCT) is a pyrrolizidine alkaloid (PA) plant toxin that produces sinusoidal endothelial cell (SEC) injury, hemorrhage, fibrin deposition, and coagulative hepatic parenchymal cell (HPC) oncosis in centrilobular regions of rat livers. Cells with apoptotic morphology have been observed in the livers of animals exposed to other PAs. Whether apoptosis occurs in the livers of MCT-treate...
Apoptosis is an important mode of cell death under both physiological and pathophysiological conditions. Numerous techniques are available for the study and quantitation of apoptosis in cell culture, but only few are useful when applied to complex tissues. Among these, the terminal transferase-mediated dUTP nick end-labeling (TUNEL) assay remains the most widely used technique. However, its spe...
Zn (II) is an important regulator of caspase-3, as well as an antioxidant, microtubule stabilizer, growth cofactor, and anti-inflammatory agent. Over the past 30 years, many researchers have demonstrated the important role of Zn (II) in a variety of physiological processes, including growth and development, maintenance and priming of the immune system, and in tissue repair and regeneration. In...
4772 Cell Cycle Volume 9 Issue 24 Apoptosis is an evolutionarily conserved and tightly reglated process in which caspases, a unique family of cysteine proteases, direct the dismantling of a dying cell. A fundamental feature of apoptosis is chromosome fragmentation, which is executed by multiple apoptotic nucleases in a stepwise manner. Apoptotic nucleases first introduce 3’ hydroxyl nicks into ...
BACKGROUND The efficacy of oxaliplatin in cancer chemotherapy is limited by the development of drug resistance. MMP7 has been related to the loss of tumor cell response to cytotoxic agents although the exact mechanism is not fully understood. Moreover, MMP7 is an independent prognosis factor for survival in patients with colorectal cancer. The aim of the present study was to analyze the role of...
The nitrogen permease regulator‑like‑2 (NPRL2) gene is a candidate tumor suppressor gene, which has been identified in the 3p21.3 human chromosome region. Decreased expression levels of NPRL2 have been observed in colorectal cancer (CRC) tissues, however, the function of NPRL2 in CRC progression remains to be fully elucidated. The present study investigated the biological characteristics of the...
We have shown previously that the death receptor CD95 could contribute to anticancer drug-induced apoptosis of colon cancer cells. In addition, anticancer drugs cooperate with CD95 cognate ligand or agonistic antibodies to trigger cancer cell apoptosis. In the present study, we show that the anticancer drug cisplatin induces clustering of CD95 at the surface of the human colon cancer cell line ...
background and aims. there is no report on the apoptotic impact of allium sativum l. (garlic) on the oral squamous cell carcinoma (kb); hence, this study was designed to survey the apoptotic effects of garlic fresh juice (gfj) on the kb cells. materials and methods. mtt assay (microculture tetrazolium assay) was carried out to evaluate the cytotoxicity of gfj on kb cells. furthermore, tunel (te...
The long non-coding RNA (lncRNA) RUSC1-AS1 has been reported to be dysregulated in the progression of many cancers. Also, had detected highly expressed laryngeal squamous cell carcinoma and breast cancer cells, suggesting that may a biomarker for However, biological role regulatory mechanism hepatocellular (HCC) remain unknown. In this study, we found was upregulated HCC tissues predicted unfav...
Apoptosis in surgically excised choroidal neovascular membranes in age-related macular degeneration.
BACKGROUND Choroidal neovascular membranes (CNVMs) in age-related macular degeneration show progressive histologic changes from active, cellular, highly vascularized membranes to inactive paucicellular scars. The purpose of this study was to determine whether apoptosis was involved in the evolution of these changes, what cell types are involved, and whether there was an association with the Fas...
