Then the Lasso and stepwise multivariate Cox regression analysis was executed to further build a signature for predicting BC prognosis, which further indicated that 4 m6A modulators including RBM15B, HNRNPC, YTHDF3, and ZC3H13 could be used to build the risk model (Fig. 2E, F). The gene discussed is HNRNPC; the disease is breast cancer.
