miR-30c-2-3p downregulates the expression of TNF receptor-associated death domain TRAND and nuclear factor kappa B (NF-κB), thereby inhibiting NF-κB–cyclin E1 (CCNE1) signaling in breast cancer cells, and it is interesting to note that patients with breast cancer who have higher miR-30c-2-3p expression tend to survive longer [9]. The gene discussed is CCNE1; the disease is breast carcinoma.
