Nitric oxide prevents anoxia-induced apoptosis in colonic HT29 cells.
Apoptosis is a critical determinant of tissue mass homeostasis and may play a role in carcinogenesis. The aim of the present study was to investigate anoxia-induced cell death in colon-derived HT29 cells and the effect of nitric oxide on this phenomenon. It was found that HT29 cells subjected to anoxia undergo apoptosis in a time dependent manner, as determined by DNA fragmentation and Hoechst-...
متن کاملDetection of apoptosis in human brainstem by TUNEL assay.
The aim of the present study was to evaluate the distribution of apoptotic neurons in the nuclei of the brainstem. Apoptosis was studied by the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay, in human brainstems taken at autopsy from 15 adults (age range: 25-58 years). The nuclei examined included the hypoglossal nucleus (XII), dorsal motor nucleus of the va...
متن کاملProtocol for Apoptosis Assay by Flow Cytometry Using Annexin V Staining Method.
This assay is used to count the number of cells that have undergone apoptosis. Apoptosis will be detected by initially staining the cells with Annexin V and propidium Iodide solution followed by flow cytometry analysis. It is based on the principle that normal cells are hydrophobic in nature as they express phosphatidyl serine in the inner membrane (side facing the cytoplasm) and when the cells...
متن کاملEffect of citric acid on Bioavailability and apoptosis induction in human colorectal Adenocarcinoma cell line (HT29)
Background and Aim: Colorectal adenocarcinoma is one of the common causes of death due to weak response to common therapies. In this study, the effect of citric acid on bioavailability and apoptosis of the human colorectal adenocarcinoma cell line (HT29) was examined. Citric acid is a naturally organic acid that commonly found in citrus and is considered as a physiological inhibitor of enzymes ...
متن کاملRutamarin, an Active Constituent from Ruta angustifolia Pers., Induced Apoptotic Cell Death in the HT29 Colon Adenocarcinoma Cell Line
BACKGROUND Ruta angustifolia Pers. is a perennial herb that is cultivated worldwide, including Southeast Asia, for the treatment of various diseases as traditional medicine. OBJECTIVE The purpose of the study was to identify an active principle of R. angustifolia and to investigate its effect on the HT29 cell death. MATERIALS AND METHODS The methanol and fractionated extracts (hexane, chlor...
