Other genes that are involved in cell proliferation, migration, invasion, inflammation, and cellular metabolism, and might be relevant for further investigation, e.g., mucins (MUC1, MUCL1, MUC5B)45,46, inflammatory signaling factors (FOS, JUNB, IL32)47,48, insulin receptor INSR, lipid transporter APOD49, were also found to be overexpressed in NST ER+/HER2− cancer cells from obese patients (Fig. 5a). This evidence concerns the gene MUC1 and cancer.
