CAMK2G and breast carcinoma: To examine the level of CaMKII phosphorylation at T286 in breast cancer tissues and to confirm that total CaMKII is overexpressed in breast cancer tissues at the protein level, CaMKII protein expression and phosphorylation at T286 was examined in 70 breast cancer, 40 matched normal breast, and 10 lymph node metastases patient samples by immunohistochemistry.
