The aim of this pilot study was to assess for the first time the clinical utility of semaphorin 3C (sema3C) and 4A (sema4A) in patients with non-muscle-invasive bladder cancer (NMIBC). <b>Methods:</b> The experiment involved 15 patients with NMIBC and 5 patients without malignancies as the control group. Plasma and urinary concentrations of sema3C and sema4A were assessed by using an enzyme-linked immunosorbent assay (ELISA). Urinary sema4A concentration was below the detection level. <b>Results:</b> There was no statistically significant difference between patients and controls in terms of plasma sema4A and sema3C or urinary sema3C concentrations (<i>p</i> > 0.05).

Furthermore, apigenin could inhibit the activities of ovarian cancer cells and alleviate the pathological changes in the female reproductive system caused by environmental pollutants, harmful medications, cancer, polycystic ovarian syndrome, ischemia, as well as endometriosis.
