Ovarian cancer is a gynecological cancer with a high death rate. We utilized global gene expression profiles of ovarian carcinomas obtained by complementary DNA (cDNA) microarray to identify ovarian cancer-specific proteins. CD9 was upregulated in ovarian carcinomas, and overexpression of the CD9 protein was detected in ovarian carcinomas by(More)
Proteins containing PDZ (postsynaptic density-95, discs large, zonula occludens) domains play a general role in recruiting receptors and enzymes to specific synaptic sites. In Caenorhabditis elegans, a complex of three PDZ proteins, LIN-2/7/10, mediates basolateral targeting of a receptor tyrosine kinase. Homologs of these LIN proteins have also been(More)
Protein assembly at the postsynaptic density (PSD) of neuronal synapses is mediated in part by protein interactions with PSD-95/discs large/zona occludens-1 (PDZ) motifs. Here, we identify MALS-1, -2, -3, a family of small synaptic proteins containing little more than a single PDZ domain. MALS-1, -2, and -3 are mammalian homologs LIN-7, a Caenorhabditis(More)
The actinin-associated LIM protein, ALP, is the prototype of a large family of proteins containing an N-terminal PDZ domain and a C-terminal LIM domain. These PDZ-LIM proteins are components of the muscle cytoskeleton and occur along the Z lines owing to interaction of the PDZ domain with the spectrin-like repeats of alpha-actinin. Because PDZ and LIM(More)
A novel series of diarylsulfonylurea derivatives were synthesized and evaluated for interaction with tubulin and for cytotoxicity against human cancer cell lines. These derivatives demonstrated good inhibitory activity against tubulin polymerization, which was well correlated with promising antiproliferative activity as well as G2/M phase cell cycle arrest.(More)
