| Popis: | Renal cell carcinoma (RCC) is among the most common subtype of kidney cancers, and the current therapeutic strategies are not efficient. Natural killer (NK) cells are biological agents that can induce apoptosis in a wide range of cancer cells. However, most of RCC patients exhibit resistance against the action of NK cells due to unknown mechanisms. This study is aimed to identify a biomarker that can predict the response of RCC cells to NK cell treatment. We collected 82 RCC patients and 19 healthy volunteers to detect the expression of miR-183 in blood by qPCR assays. The results revealed that serum miR-183 is significantly higher in RCC patients than in healthy controls, and its level is positively associated with the grading of RCC. Furthermore, (51)Cr release assays indicated that the primary RCC cells with low serum miR-183 expression are more sensitive to the cytotoxicity of NK cells. Collectively, we demonstrated that serum miR-183 can be used to predict the response of RCC cells to the cytotoxicity induced by NK cells. |
