In the second stage, cell proliferation ceases and a large fluid-filled sac, called an antrum, forms within the granulosa cell layer. Fluid continues to accumulate in the antrum until the follicle is ready to ovulate. Apoptotic nuclease assays. Delineation of the signalling pathways involved in glucocorticoid-induced and spontaneous apoptosis of rat thymocytes. A necessary role for reduced intracellular potassium during the DNA degradation phase of apoptosis.
Potassium is a critical regulator of apoptotic enzymes in vitro and in vivo.
Non-Caspase proteases are required for chromatin degradation during apoptosis. Induction of apoptosis by the novel retiniod AHPN in human T cell lymphoma cells involves caspase-dependent and independent pathways. Thymosin fraction 5 inhibits the proliferation of the rat neuroendocrine MMQ pituitary adenoma and C6 glioma cell lines in vitro. Intracellular potassium suppresses the activation of apoptosis in lymphocytes. Potential roles of cyclophilins in apoptosis.
