Furthermore, BAG3 is overexpressed in of normal cell types and constitutively in a variety of tumors, including thyroid carcinomas, where higher levels of expression are reached in pancreas carcinomas, lymphocytic and myeloblastic leukemias, and anaplastic tumors compared with well-differentiated forms.
