In cervical squamous cell carcinoma, hAnxA5 is associated with the actin gamma 1 (ACTG1) or growth factor receptor-bound protein 2 (Grb2) response, which regulates the apoptosis, proliferation, and differentiation of cancer cells and is considered a potential tumor-specific marker of cervical squamous cell carcinoma [85]. Here, GRB2 is linked to cancer.
