Heat Shock Protein 27 (G3.1)

Mouse Monoclonal


Heat shock proteins (HSPs) are a family of molecular chaperones that facilitate a host of critical cellular functions, including protein homeostasis, transport processes, and signal transduction. These proteins can be detected under normal physiological conditions but there is a general increase in expression upon exposure to cellular stresses. In cancerous disease states, HSPs function in promoting tumor cell survival.Among the members of the HSP family that have been subject to extensive study, Hsp27 has been demonstrated to be present in a variety of cancer types, including malignancies of the breast,2 colon,3 kidney,4 and cervix.5  Anti-Hsp27 has also been shown to be helpful in distinguishing between high grade cervical intraepithelial neoplasms from low grade lesions.6

Heat Shock Protein 27
High grade cervical intraepithelial neoplasia (CINIII) demonstrates strong diffuse and cytoplasmic expression of heat shock protein 27. Note the glandular component in this CINIII with glandular duct involvement is negative for HSP27.
