The cellular apoptosis susceptibility gene CAS/CSE1L is overexpressed in cancer, although it was originally identified as a gene that renders cells vulnerable to apoptotic stimuli. CAS/CSE1L has roles in the nucleocytoplasmic recycling of importin-α and in the regulation of gene expression, cell migration, and secretion. We identified CAS/CSE1L as a survival factor for ovarian cancer cells in v...

The p53 tumor suppressor gene is believed to play an important role in neuronal cell death in acute neurological disease and in neurodegeneration. The p53 signaling cascade is complex, and the mechanism by which p53 induces apoptosis is cell type-dependent. Using DNA microarray analysis, we have found a striking induction of the proapoptotic gene, SIVA. SIVA is a proapoptotic protein containing...

In this study, the therapeutic effect of Mel-incubated Adipose-derived mesenchymal stem cells (ADSCs) on CCl4-induced hepatic fibrosis was investigated. Mice with were intraperitoneally injected 8% CCl4 twice a week for 4 weeks. Starting from 5, mice in ADSC group and + Mel 1 mL PBS cell suspension containing × 106 ADSCs or pretreated 50 nM 2 consecutive Results: model group, severe histopathol...

The E2F family of transcription factors regulates the expression of both genes associated with cell proliferation and genes that regulate cell death. The net outcome is dependent on cellular context and tissue environment. The mir-11 gene is located in the last intron of the Drosophila E2F1 homolog gene dE2f1, and its expression parallels that of dE2f1. Here, we investigated the role of miR-11 ...

Activation of STAT3 in cancers leads to gene expression promoting cell proliferation and resistance to apoptosis, as well as tumor angiogenesis, invasion, and migration. In the characterization of effects of ST3-H2A2, a selective inhibitor of the STAT3 N-terminal domain (ND), we observed that the compound induced apoptotic death in cancer cells associated with robust activation of proapoptotic ...

Similar to many genes involved in programmed cell death (PCD), the caspase 2 (casp-2) gene generates both proapoptotic and antiapoptotic isoforms by alternative splicing. Using a yeast RNA-protein interaction assay, we identified RBM5 (also known as LUCA-15) as a protein that binds to casp-2 pre-mRNA. In both transfected cells and in vitro splicing assay, RBM5 enhances the formation of proapopt...
