Apoptosis is usually accompanied by DNA fragmentation and up-regulation of reactive oxygen species, and it can be inhibited by overexpression of Bcl-2. Here, cadmium was found to induce apoptosis in BA/F3beta cells. MTT assay, Hochest 33258 staining, and transmission electron microscopy analysis were used to detect the apoptosis, however, neither DNA fragmentation nor up-regulation of reactive oxygen species were observed in this type of apoptosis. Furthermore, Bcl-2 overexpression had no effect on this type of apoptosis. In conclusion, these data suggested that cadmium induced a novel type of apoptosis in BA/F3beta cells.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.


Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
