HCRP-1 regulates cell migration, invasion and angiogenesis via Src/ FAK signaling in human prostate cancer.

Prostate cancer (PCa) is the third leading malignancy engendering mortality among men globally. The present study aimed at determining the expression of hepatocellular carcinoma-related protein-1 (HCRP-1) in PCa, to explore its potential role in prostate tumorigenesis and . We evaluated HCRP-1 protein with immunohistochemistry (IHC) technology and found HCRP-1 expression was significantly low in PCa tissues (PCTs); In addition, the decreased HCRP-1 was significantly associated with TNM (tumor node metastasis) stage, advanced histology grade and gleason score.

Effect of silencing the T‑Box transcription factor TBX2 in prostate cancer PC3 and LNCaP cells.

T‑Box (TBX)‑2 is a member of the T‑box gene family, which is aberrantly expressed in numerous types of malignant tumors, and has previously been demonstrated to be conducive to tumor progression by acting as a transcription factor. However, specific information regarding the expression and function of TBX2 in prostate cancer cells remains to be elucidated. The present study demonstrated that silencing of TBX2 by TBX2 small interfering RNA inhibited cell proliferation and promoted cell senescence.

The Emerging Roles of RASSF5 in Human Malignancy.

Ras association domain family member 5 (RASSF5, also named NORE1) is an identified member of the RASSF gene family which could bind selectively to activate Ras and function as an antineoplastic effector in multiple cellular regulations. While highly expressed in majority of normal tissues, RASSF5 is epigenetically inactivated by promoter hypermethylation in numerous cancer cell lines and primary cancers, suggesting it as a potential tumor suppressor. Nevertheless, the physiologic significance of RASSF5 in tumorigenesis remains unclear.
