According to Rodríguez et al. (2015), vesicular levels of HTR7, NEUROD1, and HOXC6 mRNA are related to disease-free survival among BC patients (p < 0.05), while NANOG, HTR7, NEUROD1, and HOXC6 mRNA levels are associated with overall survival (p < 0.05) [160]. This evidence concerns the gene HOXC6 and breast cancer.
