Therefore, in this work, we have targeted dysregulated additional cell adhesion proteins, namely, catenin alpha 1 (CTNNA1), catenin beta 1 (CTNNB1), talin-1 (TLN1), vinculin (VCL), paxillin (PXN), and actinin-1 (ACTN1) via CA nano-carrier-facilitated delivery of specific siRNAs to investigate their potential therapeutic roles in inhibiting proliferation and survival of breast cancer cells in vitro and in the murine model of breast cancer. The gene discussed is TLN1; the disease is breast cancer.
