| Research Abstract |
(1) s1-1 suppressed cell death induced by anticancer agents. It regu-lated splicing, and produced an antiapoptotic Fas isoform.(2) Association of S1-1 with tumorigenesis was examined by S1-1 immunohistochemistry for 350 cancer tissue sections. However, S1-1 expression showed no correlation with cancer cell types or cancer malignancy.(3) S1-1 was also a transcription factor. It is noteworthy that S1-1 regulates both transcription and splicing.(4) Three nuclear localization sequences, and two sequences that sequester S1-1 into S1-1 nuclear bodies under reduced cellular transcriptional activity were identified in the S1-1 molecule. Manuscripts on these findings are in preparation.
