Such is the case of Spermatogenesis, which is closely related to MAPK, AMPK and TGF-β signaling pathways, of special relevance in tumorigenesis [62], and function Lactation, which is annotated to STAT5A, an important element in the development of a wide array of cancers [63] but also a critical part in inducing lactation in women through the ErbB pathway. This evidence concerns the gene STAT5A and cancer.
