Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a novel synthetic compound that sharply inhibits the activity of a protein that plays an important role in in the progression of breast and pancreatic cancers.
In the new study, to be published in the February 2015 print edition of the journal Molecular Pharmacology, the scientists showed that the compound, known as SR1848, reduces the activity and expression of the cancer-related protein called "liver receptor homolog-1" or LRH-1.
"Our study shows that SR1848 removes LRH1 from DNA, shutting down expression of LRH-1 target genes, and halts cell proliferation," said Patrick Griffin, chair of the TSRI Department of Molecular Therapeutics and director of the Translational Research Institute at Scripps Florida. "It's a compound that appears to be a promising chemical scaffold for fighting tumors that are non-responsive to standard therapies."
