Fig 1: Verification of the expression levels of JUND and MUC5B in OC tissues. The correlation coefficient R between the qRCR results and TPM value of (A) JUND or (B) MUC5B in 40 or 38 OC tissues was calculated by language R, P < .05 was statistically significant. Comparing the relative expression levels of (C) JUND (*represent P < .05) and (D) MUC5B (P = .29) between 13 chemotherapy sensitive and 14 insensitive tissues by qPCR, ß-actin as an internal reference gene. (E) The expression of JUND in chemotherapy sensitive and insensitive tissues was tested by IHC. (I) Negative expression of JUND in chemotherapy sensitive tissues of OC. (II) Positive expression of JUND in chemotherapy insensitive tissues of OC. (III) The positive rate of JUND expressed in eight chemotherapy sensitive and eight insensitive OC tissues. (F) The expression of MUC5B in chemotherapy sensitive and insensitive tissues was tested by IHC. (I) Negative expression of MUC5B in chemotherapy insensitive tissues of OC. (II) Positive expression of MUC5B in chemotherapy sensitive tissues of OC. (III) The positive rate of MUC5B expressed in eight chemotherapy sensitive and nine insensitive OC tissues. Antibodies of JunD (Abcam, ab28837, 1:200) and MUC5B (Abcam, ab87376, 1:100) were used. The size of the ruler is 50 µm
