Specifically, the identification of miRNAs such as miR-129, miR-19a-3p, and miR-30d-5p, as well as proteins like COL4A1, MAPK3, PIK3CG, and mTOR, provides valuable insights into the molecular mechanisms underpinning aggressive breast cancer subtypes, such as TNBC. The gene discussed is PIK3CG; the disease is breast cancer.
