Abstract:
Background: Heparan-sufate interacting protetin (HIP) has been known to be up-regulated and expressed in various human cancer cell lines at both transcript and protein levels. HIP\u2019s expression was related to the differentiation status and cancer development. Objective: Using a semi-quantitative PCR method to determine HIP transcript levels in benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN) and prostate cancer tissues. Subjects and methods: 30 samples of BPH, 12 samples of high-grade PIN, and 40 samples of prostate cancer were collected from patients at Viet Duc Hospital and Friendship Hospital. Total RNA was extracted from BPH, PIN and prostate cancer tissues; cDNA synthesis by reverse transcript - polymerase chain reaction (RT - PCR); HIP transcript determination using semi-quantitative PCR. Results: There was significant difference in HIP transcript levels. HIP transcript was very highly up-regulated in the prostate cancer tissues. The up-regulation of HIP transcript was lower in PIN, and lowest in BPH. HIP transcript levels in benign samples were 1/2 and 2/3 compared with cancer and PIN samples, respectively (P< 0.05). These indicated that up-regulation of HIP transcript may be an early event in tumorigenesis. Conclusions: Levels of HIP transcript were different between tissues of prostate cancer, PIN, and BPH. HIP may be a marker for pre-cancer of the prostate.
