We introduced the wild-type p16(INK4a), p21(WAF1/Cip-1), and p53 genes into the ovarian cancer cell lines SK-OV-3 (p16(INK4a) and p53 null) and OVCA-420 (p16(INK4a) and p53 wild-type) by adenoviral transfection.

Analyzing these 14 mutations in 42 previously untested breast/ovarian cancer families revealed only two families testing positive, one for BRCA1 185delAG and one for BRCA2 9254delATCAT.

Two other recurrent mutations were also identified, the 2371-2372delTG mutation in BRCA1 and the 3337C>T mutation in BRCA2 recurring in two and three unrelated individuals respectively, giving an overall prevalence 4.7% of recurrent BRCA mutations in ovarian cancer in the Southern Chinese population.
Overexpression of alpha(v)beta6 integrin in serous epithelial ovarian cancer regulates extracellular matrix degradation via the plasminogen activation cascade.
Immunolocalization of osteopontin showed that tissue samples from 61 patients with invasive ovarian cancer and 29 patients with borderline ovarian tumors expressed higher levels of osteopontin than tissue samples from 6 patients with benign tumors and samples of healthy ovarian epithelium from 3 patients (P =.03).
Abnormalities of epidermal growth factor receptor (EGFR) and Her-2/neu have been actively investigated in ovarian cancer and associated with unfavorable clinical outcome.
We examined TK1 gene expression by RT-PCR and related it to gene expression of TS, TP and DPD in 69 samples from epithelial ovarian cancer, 8 low-malignant-potential tumors, 16 benign ovarian tumors and 34 normal ovaries.
