Kindlin-2 promotes invasiveness of prostate cancer cells via NF-κB-dependent upregulation of matrix metalloproteinases.

Invasive progression is the major lethal cause of prostate cancer. In this study, we aimed to investigate the role of kindlin-2, an integrin-binding focal adhesion protein, in the regulation of invasiveness of prostate cancer. We found that downregulation of kindlin-2 using small interfering RNA (siRNA) technology significantly inhibited the invasion of PC-3 and DU-145 prostate cancer cells in a Matrigel Transwell assay.

[Effects of adenovirus-mediated PTEN on the proliferation of prostate cancer PC-3 cells and expressions of cyclin D1 and p21].

Objective: To construct a recombinant adenovirus expression vector containing the anti-oncogene PTEN and to investigate the effects of the PTEN gene on the proliferation of prostate cancer PC-3 cells and the expressions of cyclin D1 and p21 in the PC-3 cells.

Methods: The PTEN gene was amplified from the rat hippocampus by RT-PCR and cloned into the shuttle plasmid pEN-TR2A. The plasmids were constructed and amplified in 293A cells.
