Background

Heat shock protein 27 (Hsp27) also known as heat shock protein beta-1 (HSPB1) is a protein that in humans is encoded by the HSPB1 gene.Hsp27 is a chaperone of the sHsp (small heat shock protein) group among ubiquitin, α-crystallin, Hsp20 and others. The common functions of sHsps are chaperone activity, thermotolerance, inhibition of apoptosis, regulation of cell development, and cell differentiation. They also take part in signal transduction.Hsp70 member proteins, including Hsp72, inhibit apoptosis by acting on the caspase-dependent pathway and against apoptosis-inducing agents such as tumor necrosis factor-α (TNFα), staurosporin, and doxorubicin. This role leads to its involvement in many pathological processes, such as oncogenesis, neurodegeneration, and senescence. In particular, overexpression of HSP72 has been linked to the development some cancers, such as hepatocellular carcinoma, gastric cancers, colonic tumors, breast cancers, and lung cancers, which led to its use as a prognostic marker for these cancers.[25] Notably, phosphorylated Hsp27 increases human prostate cancer (PCa) cell invasion, enhances cell proliferation, and suppresses Fas-induced apoptosis in human PCa cells. Unphosphorylated Hsp27 has been shown to act as an actin capping protein, preventing actin reorganization and, consequently, cell adhesion and motility. OGX-427, which targets HSP27 through an antisense mechanism, is currently undergoing testing in clinical trials.
