项目摘要
Overexpression of S100A4 is frequently found in pancreatic and lung cancers. Knockdown suppresses cell growth and forced expression promotes cell motility in both of the cancer types. Furthermore, we analyzed primary resected pancreatic cancer tissues immunohistochemically and found positive association between overexpression of S100A4 and tumor cell invasion, particularly to nerves. Microarray analyses after forced expression in S100A4-low expressing cells identified candidate downstream genes and we are now analyzing functions of these genes.Because overexpression of S100A4 and poor prognoses after gemcitabine treatment was reported in pancreatic cancer, we established 8 cancer cell lines with acquired gemcitabine resistance; these include four pancreatic, one gastric, one colon, one gallbladder, one bile duct cancers. Frequent inactivating mutation in deoxycytidine kinase was observed, and further investigation is on the way.
S100 A4的过度表达经常在胰腺癌和肺癌中发现。在这两种癌症类型中,敲低抑制细胞生长,强制表达促进细胞运动。此外,我们对原发性切除的胰腺癌组织进行了化学分析,发现S100 A4的过表达与肿瘤细胞浸润,特别是神经浸润呈正相关。在S100 A4-低表达细胞中强制表达后的微阵列分析鉴定了候选下游基因,我们现在正在分析这些基因的功能。由于在胰腺癌中报道了S100 A4的过表达和吉西他滨治疗后的低表达,我们建立了8个获得性吉西他滨耐药的癌细胞系;这些细胞系包括4个胰腺癌,1个胃癌,1个结肠癌,1个胆囊癌,1个胆管癌。在脱氧胞苷激酶中发现了频繁的失活突变,进一步的研究正在进行中。
