MYL5 and breast neoplasm: In our study, we found that with the analysis data via using TIMER and GEPIA tool, MYL5 expression negatively correlated with macrophages infiltration in breast tumor patients, and negatively and markedly correlated with the gene markers of macrophages and TAMs, indicating that MYL5 might affect the prognosis via regulating the TAMs in TME, thereby causing in longer survival in breast tumor patients.
