As has been reported, HA binding to CD44 enhances proliferation and survival of breast cancer cells through modulating β-catenin signaling and nuclear factor-kappa B (NFκB)-specific transcription activity and subsequently promoting the expression of P-glycoprotein and B-cell lymphoma-extra large (Bcl-xl) genes in breast cancer MCF-7 cells [63]. Here, BCL2L1 is linked to breast carcinoma.
