The Expression of PI3K/AkT/mTOR pathway proteins was quantified using immunohistochemistry across age groups: Young-adults (YA: 20-39 years), Middle-Aged (MA: 40-59 years) and Older-Adults (OA: 60-79 years), also among BC subtypes: Estrogen Receptor-positive (ER+), Estrogen Receptor-positive/Progesterone Receptor-Positive (ER+/PR+), Human Epidermal Receptor 2-positive (HER2-positive), and triple-negative breast cancers (TNBC) tumors. This evidence concerns the gene AKT1 and triple-negative breast carcinoma.
