BACKGROUND In this study, we investigated the importance of apoptosis for cell death after radiotherapy, and whether the expression of pro- and anti-apoptotic proteins has any correlation to the radiosensitivity. METHODS Three oral squamous cell carcinoma cell lines, UT-SCC-2, UT-SCC-9 and UT-SCC-24A, were subjected to radiotherapy. After irradiation, viable and dead cells were counted to det...
Objective(s): Scutellarin (Scu) is the main effective constituent of Erigeron breviscapuswhich hasanti-oxidant, anti-apoptotic, anti-inflammatory and other therapeutic properties. The purpose of this study was to investigate the protective effect of Scu on myocardial infarction (MI) induced by isoprenaline (ISO). Materials and Methods: The rats were subcutaneously injected with ISO (45 mg/kg) o...
Cisplatin (CDDP) is a chemotherapeutic agent that is widely used to treat many cancers. However, initial resistance to CDDP is a serious problem in treating cancers. In this study, in order to develop an approach to overcome resistance to CDDP, we investigated the difference in apoptotic processes between CDDP-sensitive cells and CDDP-resistant cells. By screening with CDDP sensitivity tests, w...
Release of apoptogenic proteins such as cytochrome c from mitochondria is regulated by pro- and anti-apoptotic Bcl-2 family proteins, with pro-apoptotic BH3-only proteins activating Bax and Bak. Current models assume that apoptosis induction occurs via the binding and inactivation of anti-apoptotic Bcl-2 proteins by BH3-only proteins or by direct binding to Bax. Here, we analyze apoptosis induc...
Activation of apoptotic signalling in endothelial cells contributes to the detrimental effects of a variety of pathological stimuli. In investigating the molecular events underlying the anti-apoptotic effect of human plasma in cultured human endothelial cells, we unexpectedly uncovered a novel mechanism of apoptosis suppression by human plasma through an interaction between two previously unrel...
Apoptosis, cell death executed by caspases, is essential to normal breast development and homeostasis. Pro-apoptotic and anti-apoptotic signals are tightly regulated in normal breast epithelial cells. Dysregulation of this balance is required for breast tumorigenesis and increases acquired resistance to treatments, including molecularly targeted therapies, radiation and chemotherapies. The pro-...
background: there is accumulating evidence that a polyphenol present in olive oil, oleuropein, has antioxidant, anti-inflammatory and anti-apoptotic effects. this study aimed at determining the anti-apoptotic effect of oleuropein (ole) on dexamethasone-induced apoptosis of mouse thymocytes. method: mice were randomly divided to four groups as follow: dexamethasone (dex)-treated group (20 mg/kg;...
different treatment strategies of alzheimer's disease (ad) are being studied for treating or slowing the progression of ad. many pharmaceutically important regulation systems operate through proteins as drug targets. here, we investigate the drug target proteins in beta-amyloid (aβ) injected rat hippocampus treated with lavandula angustifolia (la) by proteomics techniques. the reported stu...
Anthocyanins belong to a class of flavonoids that exhibit important anti-oxidant and anti-inflammatory actions as well as chemotherapeutic effects. However, little is known concerning the molecular mechanisms by which these activities are exerted. In this study, we investigated the anthocyanins isolated from Vitis coignetiae Pulliat for their potential anti-proliferative and apoptotic effects o...
Background: Cisplatin is an effective chemotherapy but its main side effect, acute kidney injury, limits use. Panduratin A, a bioactive compound extracted from Boesenbergia rotunda, shows several biological activities such as anti-oxidative effects. The present study investigated the nephroprotective effect of panduratin A on cisplatin-induced renal injury. Methods: We toxicity cisplatin in bot...
