(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.

(1)S1-1可抑制抗癌药物诱导的细胞死亡。(2)用免疫组织化学方法检测了350例癌组织标本中S1-1与肿瘤发生的关系。但S1-1的表达与癌细胞类型、肿瘤的恶性程度无关。(3)S1-1也是一种转录因子。值得注意的是，S1-1同时调节转录和剪接。(4)在S1-1分子中发现了三个核定位序列和两个在细胞转录活性降低的情况下将S1-1隔离到S1-1核体中的序列。关于这些发现的手稿正在准备中。
