(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抑制抗癌药物诱导的细胞死亡。它调节剪接，并产生抗凋亡的Fas亚型。(2)对350例肿瘤组织切片进行S1-1免疫组化检测S1-1与肿瘤发生的关系。而S1-1表达与肿瘤细胞类型及恶性程度无相关性。(3) S1-1也是一个转录因子。值得注意的是，S1-1同时调控转录和剪接。(4)在S1-1分子中鉴定出3个核定位序列和2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。
