In this study, we show that the transmembrane glycoprotein Trop-2 is up-regulated in human prostate cancer (PCa) with extracapsular extension (stages pT3/pT4) as compared to organ-confined (stage pT2) PCa. Consistent with this evidence, Trop-2 expression is found to be increased in metastatic prostate tumors of Transgenic Adenocarcinoma of Mouse Prostate… (More)
We have examined several microRNAs (miRs) indicated by the databases as targeting the signaling pathway of the type-1 insulin-like growth factor receptor (IGF-IR). Most of the miRs tested had multiple targets, as expected, leading to cell death. However, miR145 seemed to affect its tumor suppressor activity largely by downregulating the docking protein of… (More)
The expression of selected metalloproteinases and tissue inhibitors of metalloproteinases (TIMP) was examined in three squamous cell carcinoma (SCC) cell lines (FaDu, SiHa, A431) and a keratinocyte cell line (HaCaT) to determine which metalloproteinases function in SCC invasiveness. A Matrigel invasion assay was used to assess invasiveness of the cell… (More)
