To investigate whether the MAPK pathway associated protein was involved in miR-532-5p-KRAS/NAP1L1-modulated cell proliferation in RCC, we performed WB analysis, which showed that miR-532-5p could blunt KRAS-NAP1L1/P-ERK signalling in both SN12-PM6 and 786-O cell lines (Fig. 4b). The gene discussed is NAP1L1; the disease is renal cell carcinoma.
