We have recently isolated a gene, Ankyrin-repeated protein with a proline-rich region (ARPP), that is highly expressed in the skeletal and cardiac muscle. Our previous immunohistochemical analysis revealed that ARPP expression was augmented in rhabdomyosarcoma but scarcely detectable in
We report details of a family with classic Li-Fraumeni syndrome in which there is a mutation in codon 344 of the tumour suppressor gene TP53. Codon 344 is a key residue within the tetramerisation domain, and the amino acid substitution of a proline for a leucine is predicted to have profound
Activators of G-protein signaling 1-3 (AGS1-3) were identified in a functional screen of mammalian cDNAs that activated G-protein signaling in the absence of a receptor. We report the isolation and characterization of an additional AGS protein (AGS4) from a human prostate leiomyosarcoma cDNA
Type IV collagenase matrix metalloproteinases (MMPs), especially MMP-2 and MMP-9, have been found to promote invasion and metastasis of malignant tumors. Extracellular matrix (ECM) degradation by MMPs and increased expression of MMPs in cancer cells and tumor microvascular endothelial cells make
