The high expression of OPA1 showed statistically significant with P < 0.05 in both breast and gastric cancer (P = 1.6e-06, respectively); while SENP5 was associated with RFS in the other two cancer types – ovarian cancer (P = 0.011) and gastric cancer (P = 1.1e-05). Here, SENP5 is linked to ovarian carcinoma.
