Structural and functional properties of proteins interacting with small heat shock proteins

HDAC Inhibitors and Heat Shock Proteins (Hsps)

Epigenetic alterations, including DNA acetylation, hypermethylation and hypomethylation, and the associated transcriptional changes of the affected genes are central to the evolution and progression of various human cancers, including pancreatic cancer. Cancer-associated epigenetic alterations are attractive therapeutic targets because such epigenetic alterations, unlike genetic changes, are po...

The Relationship between the Expression of Small Heat-Shock Proteins and Suppression of OCT4B1

Background: OCT4B1, a variant of OCT4, is expressed in both cancer cells and tissues. This variant has a main role in the regulation of both apoptotic and stress (heat-shock proteins) pathways. The aim of this study was to investigate the effects of OCT4B1 silencing on the expression of small heat-shock proteins (sHSPs)in three human tumor cell lines. Methods:...

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Multiple small heat shock proteins in rhizobia.

Seven genes coding for small heat shock proteins (sHsps) in Bradyrhizobium japonicum have been identified. They are organized in five operons that are coordinately regulated by ROSE, a negatively cis-acting DNA element. The deduced sHsps can be divided into two separate classes: class A, consisting of proteins that show similarity to Escherichia coli IbpA and IbpB, and class B, whose members di...

Heat shock and the heat shock proteins.

As all biologists appreciate, there is constant interaction between life and the environment, and temperature plays a critical role. It establishes distribution limits, it affects rates of function as well as the survival of organisms. Notoriously sensitive to temperature is plant growth. Critical steps in plant life such as germination, flowering and breaking of dormancy can be manipulated by ...
