High serum HTATIP2/TIP30 level in serous ovarian cancer as prognostic or diagnostic marker.

Human HIV-1 TAT interactive protein 2 (HTATIP2/TIP30) is an evolutionarily conserved gene that is expressed ubiquitously in human tissues and some tumor tissues. This protein has been found to be associated with some gynecological cancers; as such, this study aimed to investigate blood HTATIP2/TIP30 levels in patients with ovarian cancer. Twenty-three women with ovarian cancer and 18 patients with various non-cancerous gynecological complaints (for example, dysfunctional uterine bleeding, fibroids, and urinary incontinence) were included in the study. The pathological diagnosis of ovarian cancer was adenocarcinoma. HTATIP2/TIP30 concentration in the patients' blood samples was determined using ELISA kits. The HTATIP2/TIP30 level was significantly higher in the cancer group than in the control group (1.84 ± 0.82 versus 0.57 ± 0.13 ng/ml, mean ± SD). We demonstrated the potential role of HTATIP2/TIP30 in ovarian cancer for the first time, thereby enlightening future studies targeting HTATIP2/TIP30 in ovarian cancer treatment, diagnosis, and prevention.
