Biochem/physiol Actions
Heat shock proteins (HSPs) are molecular chaperones. They prevent aggregation of unfolded proteins. HSP27 is involved in anti-apoptosis and actin, and microtubule stabilization. It exists in unphosphorylated inactive form and phosphorylated active form. In monocytes, phosphorylated HSP27 is associated with bone mineral density and can contribute to the pathogenesis of osteoporosis. It also participates in iron metabolism and negatively regulates ferroptosis-associated cancer cell death.

We investigated the relationship between HSP27 phosphorylation and collagen-stimulated activation of platelets in patients with diabetes mellitus (DM). Platelet-rich plasma was prepared from blood of type 2 DM patients. The platelet aggregation was analyzed in size of aggregates by an

A hybrid protein containing the N-terminal part of the murine stress protein hsp25 (amino acids 1 to 110) and the C-terminal part of the human stress protein hsp27 (amino acids 111 to 208) was expressed in E. coli using a

Peripheral monocytes, precursors of osteoclasts, have emerged as important candidates for identifying proteins relevant to osteoporosis, a condition characterized by low Bone Mineral Density (BMD) and increased susceptibility for fractures. We employed 4-plex iTRAQ (isobaric tags for relative and absolute

Ferroptosis is an iron-dependent form of non-apoptotic cell death, but its molecular mechanism remains largely unknown. Here, we demonstrate that heat shock protein beta-1 (HSPB1) is a negative regulator of ferroptotic cancer cell death. Erastin, a specific ferroptosis-inducing compound, stimulates
