  • Introduction: Renal cell carcinoma (RCC) is the most common type (>80%) of kidney cancer. Claiming more than 100,000 lives per year worldwide, RCC accounts for about 3% of all adult cancers and its incidence is rising. With newer therapies, the median survival period of patients with advanced RCC is about 26 months. MicroRNAs (miRNA), are small noncoding RNAs that are emerging as important modulators in cellular pathways and appear to play a role in tumorigenesis, cell cycle, proliferation and apoptosis. So we purpose to evaluate the role of Ras, IKK, NFkB1, PI3K by mir-3120d, 199a-5p in renal cancer.
  • Methods: The feature of microRNA was archived by using mirbase. Target genes and predict one were identified by mirtarbase and mirwalk 2.0. Gene expression in normal and tumor tissue was obtained from NCBI. Finally, the pathway enrichment analysis was performed by the KEGG and David. GENEMANIA used to find gene network.
  • Results: The result dedicated that mir-199a-5p and 3120d by inhibiting Ras which actives Raf1, MEK, ERK through phosphorylation prevent proliferation of cancer cell and angiogenesis. IKK, NFkB were inhibited by blocking PI3K, which actives Ras. So MYC, BCL through inhibition cell survival, suppress cancer. Mir-199a5p, and 3120d by inhibiting Ras, PI3K, IKK, NFkB through preventing cell cycle, prevent cancer development. Mentioned microRNAs, block NFkB by inhibiting PI3K which actives Act. So NFkB by inhibiting VEGF, suppresses cancer through inhibition angiogenesis.
  • Conclusion: Mir-199a-5p, 3120d by effecting on Ras, IKK, NFkB1, PI3K, in PI3K-Act, RAS, TNF and renal pathway effect on proliferation, angiogenesis and cell survival. Mentioned microRNAs by acting as tumor suppressor prevent cancer development and tumor spread by inhibiting proliferation of cancer cell, angiogenesis and sell survival.
