Li et al. (2016) reported the relationship of the pri-let-7a-1 rs10739971 polymorphism with the prognosis of gastric cancer patients in northern China (Li et al., 2016). M. tuberculosis suppresses the innate immune response in macrophages, when suppressing miRNA let-7f expression, and modulates the immune response to TB infection by elevating target expression, A20, an inhibitor of the NF-κB pathway (Kumar et al., 2015). The gene discussed is NFKB1; the disease is gastric cancer.
