KLK3 and prostate carcinoma: The association between miR-205 pronouncement level and pathological and clinical manifestations of people with prostate tumor was analyzed using chi-squared test, and the findings revealed that the miR-205 pronouncement in serum exosomes of prostate tumor patients was significantly negatively linked with carcinoma stage, uncontrolled cell division in lymph node, distant metastasis, and PSA level at initial diagnosis in prostate cancer patients (Figures 2(c) and 2(d)), while the relationship with age of patients was not statistically significant (Table 1).
