GEPIA2 database analysis revealed significant overexpression of five collagen types in breast cancer tissues: COL10A1, COL11A1, collagen type I alpha 1, collagen type XXII alpha 1, and collagen type III alpha 1, and they influence key processes like proliferation, metastasis, apoptosis, and drug resistance, shaping cancer progression and prognosis [6]. This evidence concerns the gene COL11A1 and breast cancer.
