Bcl-2 Oncoprotein Information for Pathologists
BCL2 is a proto-oncogene at locus 18q21.3 the plays a role in inhibiting apoptosis. The BCL2 protein has a M.W. of 25 kDa.
Common Uses By Pathologists:
BCL2 staining is used to distinguish follicular hyperplasia of lymph node (germinal centers are BCL2 negative) from follicular lymphoma (germinal centers are BCL2 positive). However, there are reported cases of follicular lymphomas that are BCL2 negative (Am J Surg Pathol 2011;35:1691, Am J Surg Pathol 2009;33:591). BCL2 staining can also identify immature enteric ganglion cells in pediatric intestinal pseudo-obstruction (Am J Surg Pathol 2005;29:1017). BCL2 antibodies label diffuse large cell lymphoma which is an adverse prognostic factor in some studies (Mod Pathol 2005;18:1113, Clin Cancer Res 2011;15:7785). Myelodysplastic syndrome patients should be screened for BCL2 as increased expression is associated with progression. Finally, BCL2 may have prognostic value in early stage breast cancer (Br J Cancer 2010;103:668).
