introduction: repetitive cortical spreading depression (csd) can lead to cell death in immature brain tissue. caspases are involved in neuronal cell death in several csd-related neurological disorders. yet, whether repetitive csd itself can induce caspase activation in adult or juvenile tissue remains unknown. inducing repetitive csd in somatosensory cortices of juvenile and adult rats in vivo,...

The influence of heat shock proteins (HSPs) on protein quality control systems in cardiomyocytes is currently under investigation. effect HSPs the regulated cell death (CMCs) great importance, since they play a major role implementation compensatory and adaptive mechanisms event cardiac damage. mediate number that activate apoptotic cascade, playing both pro‑ anti‑apoptotic roles depending thei...

Apoptosis or programmed cell death is a tightly regulated process fundamental for cellular development and elimination of damaged or infected cells during the maintenance of cellular homeostasis. It is also an important cellular defense mechanism against viral invasion. In many instances, abnormal regulation of apoptosis has been associated with a number of diseases, including cancer developmen...

Research during the past several decades has provided convincing evidence for a crucial role of the Ca(2+) ion in cell signaling. Hence, intracellular Ca(2+) transients have been implicated in most aspects of cell physiology, including gene transcription, cell cycle regulation and cell proliferation. Further, the Ca(2+) ion has been found to also play an important role in cell death regulation....

objective: breast cancer is the second leading cause of cancer death in women. cisplatin is a traditional cancer drug commonly used in chemotherapy for killing cancer cells. modulation at the mrna levels of apoptotic related genes often correlate with the sensitivity of various types of cancer cells to chemotherapeutic agents. nanoparticulate drug delivery systems are being developed to effecti...

the objective of this study was to observe the apoptosis-inducing effect and mechanism of baicalin on human cervical cancer hela cells. the inhibitory effect of baicalin on the growth of hela cells was measured by mtt assay, and cell proliferation and migration was analyzed by cell scratch assay. morphological changes of apoptotic cells were viewed by the light microscope and electron microscop...
