This study aimed to explore the influences of microRNA-195 (miRNA-195)/Rap2C/MAPK in the proliferation and apoptosis of small cell lung cancer (SCLC) cells. QRT-PCR analysis were executed to evaluate miRNA-195 expression in lung cancer tissues and SCLC cells, and the western blot was implemented to monitor Rap2C protein level and uncovered whether the MAPK signaling pathway in lung cancer tissues and SCLC cells was activated. The CCK-8 experiment was performed to detect cell proliferation ability, and the flow cytometry was utilized to examine cell apoptosis level. Luciferase reporter gene system was executed to disclose the interaction between miRNA-195 and Rap2C. Subcutaneous implantation mouse models of SCLC cells were constructed to detect cell proliferation in vivo, and Kaplan-Meier method calculated patient survival. The expression of Rap2C was higher in lung cancer tissues and SCLC cells than in normal tissues and cells, while the expression of miRNA-195 was lower in lung cancer tissues and SCLC cells than in normal tissues and cells. miRNA-195 lower expression predicted showed reduced overall survival in lung cancer patients. Further loss of function and enhancement experiments revealed that miRNA-195 overexpression could significantly inhibit SCLC cell proliferation and promote cell apoptosis by upregulation of Bax and down-regulation of bcl-2; Luciferase reporter assay demonstrated that miRNA-195 could bind to Rap2C mRNA and inhibit its expression, Rap2C overexpression also related to the poorer prognosis of lung patients. Knockdown of Rap2C suppressed cell proliferation and expedited apoptosis. In addition, overexpression of Rap2C reversed miRNA-195-induced apoptosis and proliferation inhibition. Furthermore, miRNA195 prohibited the activation of MAPK signaling pathway by down-regulating Rap2C. These consequences indicated that miRNA-195 promotes the apoptosis and inhibits the proliferation of small cell lung cancer (SCLC) cells via inhibiting Rap2C protein-dependent MAPK signal transduction
