A Clinical Study On The Expression Of Mir-195 In Cardiac Carcinoma

Background: Recently, some studies have revealed that microRNAs (miRs; miRNAs) mainly regulate gene expression in the transcription of microRNAs. However, the role of microRNAs in cell development, differentiation, proliferation, and other physiological processes remains unclear.Objectives: The present study aimed to investigate the expression level of microRNA-195 in the pathological tissues of patients with cardiac carcinoma and its clinical effects.Methods: Patients with primary cardiac carcinoma were enrolled as the study subjects. The tumor and adjacent tissue samples for cancer pathology were obtained during the operation. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of microRNA-195 and its correlation with the clinicopathological features of cardiac carcinoma was analyzed.Results: Atotal of 64 patients were included in this study. Firstly, the expression rate of miR-195 in cardiac carcinoma tissues showed a significant decreasing trend (3.65 +/- 0.42 vs. 2.05 +/- 0.33) (P < 0.0 01) and the actual expression level of miR-195 in pathological tissues of cardiac carcinoma was negatively correlated with the malignant degree of pathological tissues (P = 0.028), invasion (P = 0.037), and lymph node metastasis of cardiac carcinoma (P = 0.023), but miR-195 was not correlated with age (P = 0.615) and gender (P = 0.465).Conclusions: The expression of microRNA-195 is closely correlated to the severity of cardiac carcinoma and the occurrence of lymph node metastasis.
