However, β2M expression shows no significant correlation with HIF-1α, p-CREB, VEGF, p-SGK1, p-ERK1/2, and Bcl-2 except for VEGF, which shows a strong positive correlation with Bcl-2 in cancer tissues of patients with basal-like breast cancer, thereby showing discordance with the results obtained from the same molecular types of breast cancer cells. Here, VEGFA is linked to cancer.
