Genetic analyses of Caenorhabditis elegans has identified three genes that function in the regulation of nematode cell death. Mammalian homologs of two of these genes, ced-9 and ced-3, have been identified and comprise proteins belonging to the Bcl-2 and ICE families, respectively. To date, it is unclear where the negative regulators, ced-9 and bcl-2, function relative to the death effectors, ced-3 and the mammalian ced-3 homologs, respectively. Here, the molecular order of the cell death pathway is defined. Our results establish that Bcl-2 and Bcl-xL function upstream of two members of the ICE/CED-3 family of cysteine proteases, Yama (CPP32/apopain) and ICE-LAP3 (Mch3).

Alzheimer's disease (AD) is the major cause of dementia, accounting for 50% to 70% of the late-onset patients, with 17 to 20 million affected. It is characterized by neurofibrillary tangles, neuronal loss, and amyloid plaques in tissues of the cortex, hippocampus, and amygdala. Apoptosis or programmed cell death appears in the progression of AD. In this study, we investigated the gene expression of 14 apoptotic genes (E2F1, p21/WAF, ICE-LAP3, Fas Antigen, CPP-32, GADD153, ICE-beta, c-Fos, c-Jun, Bax-alpha, Bcl-2, Bcl-(x)L, BAK, and p53) in 5 normal and 6 AD human hippocampal tissues, using reverse transcription-polymerase chain reaction. Our results show an upregulation of gene expression in AD patients for c-Fos and BAK. ICE-beta, c-Jun, Bax-alpha, Bcl-x(L), p53, and GADD153 were found to be upregulated in some AD samples but were not detected or downregulated in other AD or normal samples. No gene expression was found for E2F1 , p21/WAF, ICE-LAP3, Fas Antigen, CPP32, or Bcl-2. These results indicate significant increases in c-Fos , c-Jun, and Bak; therefore, we suggest that these genes may be critical in the apoptotic cascades of AD.
