Patent number: 9012145Abstract: Tyrosine phosphorylation, regulated by protein tyrosine phosphatases (PTPs) and kinases (PTKs), is important in signaling pathways underlying tumorigenesis. A mutational analysis of the tyrosine phosphatase gene superfamily in human cancers identified 83 somatic mutations in six PTPs (PTPRF, PTPRG, PTPRT, PTPN3, PTPN13, PTPN14), affecting 26% of colorectal cancers and a smaller fraction of lung, breast and gastric cancers. Fifteen mutations were nonsense, frameshift or splice site alterations predicted to result in truncated proteins lacking phosphatase activity. Five missense mutations in the most commonly altered PTP (PTPRT) were biochemically examined and found to reduce phosphatase activity. Expression of wild-type but not a mutant PTPRT in human cancer cells inhibited cell growth. These observations suggest that the tyrosine phosphatase genes are tumor suppressor genes, regulating cellular pathways that may be amenable to therapeutic intervention.Type: GrantFiled: October 18, 2011Date of Patent: April 21, 2015Assignee: The Johns Hopkins UniversityInventors: Zhenghe Wang, Victor Velculescu, Kenneth W.

Publication number: 20150051097Abstract: Methods of screening for candidate compounds capable of inhibiting activity of fyn in phosphorylating tau protein at Y394 or binding to fyn to inhibit interaction with tau protein at Y394, including determining whether, and optionally the extent, the candidate compounds have these capabilities under conditions where fyn has these capabilities in the absence of the candidate compound. Methods of screening for substances capable of promoting dephosphorylation of tau protein by a phosphatase at a site of tau protein including contacting a candidate substance, the tau protein and a phosphatase capable of dephosphorylating the tau protein under conditions where the phosphatase is capable of dephosphorylating the site in absence of the candidate substance, where the kinase is fyn; determining whether, and optionally the extent, the candidate substance promotes dephosphorylation of the tau protein at the site; and selecting the candidate substance which promotes dephosphorylation of the tau protein the sites.Type: ApplicationFiled: July 24, 2014Publication date: February 19, 2015Applicants: Proteome Sciences PLC, King's College LondonInventors: Brian Anderton, Diane Hanger, Malcolm Ward, Helen Byers
