Analysis of the Interaction of Small Heat Shock Proteins with Unfolding Proteins

INTERACTION OF PROTEINS WITH SMALL MOLECULES

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:...

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...

Interaction of viral oncogenic proteins with the Wnt signaling pathway

It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...

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...
