For example, CAMK1D promotes the proliferation of breast cancer through CERB/CCND1 (15), inhibits the angiogenesis of lung adenocarcinoma by HH3 (17), enhances the resistance of multiple myeloma to T cells by phosphorylation of caspase-3 and caspase-6 (27), and inhibits the apoptosis of human choroidal trophoblastic cells (28). Here, CCND1 is linked to breast cancer.
