RASSF1 and neoplasm: Whereas, the mRNA levels of CDKN2B (0.128 ± 0.034 vs. 1.172 ± 0.740, p < 0.001, student’s t test) were significantly lower in the mesenchymal-like OCSPCs from ascites than those from bulk tumor tissues, but CCND2 (0.824 ± 0.325 vs. 0.733 ± 0.583, p = 0.441, student’s t test), RASSF1A (2.987 ± 0.872 vs. 2.150 ± 1.630, p = 0.066, student’s t test) and DLC1 (1.068 ± 0.357 vs. 1.985 ± 1.099, p = 0.051, student’s t test) remained similar in the mesenchymal-like OCSPCs from ascites than those from bulk tumor tissues.
