Activation of the caspase cascade is involved in the execution of apoptosis in a variety of cellular systems. Recent studies demonstrated that caspase-1 activation was required for human prostate cancer cells to undergo apoptosis in response to transforming growth factor-beta (Y. Guo and N. Kyprianou, Cancer Res., 59: 1366-1371, 1999). In the present study,(More)
Infiltration of leukocytes into tissue is a common feature of many physiological and pathological conditions. Histopathologically, the diversity of leukocytes that infiltrate a tissue associated with a pathophysiologic response cannot be appreciated and/or examined unless highly selective immunologic detection methods are utilized. Specific populations of(More)
Circadian clocks regulate a wide variety of processes ranging from gene expression to behavior. At the molecular level, circadian rhythms are thought to be produced by a set of clock genes and proteins interconnected to form transcriptional-translational feedback loops. Rhythmic gene expression was formerly regarded as the major drive for rhythms in clock(More)
Apoptosis, a physiologically critical process, is characterized by a destruction of the cell after sequential degradation of key cellular components. Here, we set out to explore the fate of the physiologically indispensable nuclear envelope (NE) in this process. The NE mediates the critical nucleocytoplasmic transport through nuclear pore complexes (NPCs).(More)
