We also examined ARHGAP26 protein expression in ovarian cancer tissues via IHC analysis, which showed that ARHGAP26 protein expression was markedly decreased in tumor tissues; 57.6% (49/85) of ovarian cancer tissues displayed negative or low expression of ARHGAP26 (<25% of tumor cells were positively stained) (Fig. 1c). The gene discussed is ARHGAP26; the disease is ovarian carcinoma.
