Real-time detection of caspase-3-like protease activation in vivo using fluorescence resonance energy transfer during plant programmed cell death induced by ultraviolet C overexposure.
Caspase-like proteases have been demonstrated to be involved in plant programmed cell death (PCD). Here, the time scale of caspase-3-like protease activation was investigated in single living plant cells undergoing PCD induced by ultraviolet C (UV-C) overexposure. The real-time detection of caspase-3-like protease activation was achieved by measuring the degree of fluorescence resonance energy ...
متن کاملOn-line monitoring of apoptosis in insulin-secreting cells.
Apoptosis was monitored in intact insulin-producing cells both with microfluorometry and with two-photon laser scanning microscopy (TPLSM), using a fluorescent protein based on fluorescence resonance energy transfer (FRET). TPLSM offers three-dimensional spatial information that can be obtained relatively deep in tissues. This provides a potential for future in vivo studies of apoptosis. The ce...
متن کاملDetection of caspase-3 activation in single cells by fluorescence resonance energy transfer during photodynamic therapy induced apoptosis.
In many apoptosis pathways, activation of caspase-3 is considered the final stage. In this study, we studied PDT induced caspase-3 activation with fluorescence resonance energy transfer (FRET) technique. A recombinant caspase-3 substrate, SCAT3, was used as the FRET probe. FRET fluorescence images were collected after PDT or TNF-alpha induced apoptosis. By analyzing the dynamic changes of FRET ...
متن کاملRequirement of caspase-3(-like) protease-mediated hydrogen peroxide production for apoptosis induced by various anticancer drugs.
Caspase-3(-like) proteases play important roles in controlling mammalian apoptosis. However, the downstream events from the caspase-3(-like) protease activation to death of cells are still unclear. Previously, we reported that hydrogen peroxide (H2O2) was generated by the activation of caspase-3(-like) proteases in the process of tyrosine kinase inhibitor-induced apoptosis in human small cell l...
متن کاملImpact of Duration and Severity of Persistent Pain on Programmed Cell Death
Programmed cell death is a highly regulated form of cell death, mostly distinguished by the activation of a family of cystein-aspartate proteases (caspases) that cleave various proteins resulting in morphological and biochemical changes characteristic of this form of cell death. Several recent studies have addressed the role of programmed cell death in inflammatory and chronic pain states. Casp...
