摘要: Loss of heterozygosity (LOH) on chromosome arm 7q31 is found in many prostate tumors. Such alterations are generally associated with inactivation tumor suppressor genes. It has been shown previously that the main region LOH at spans interval between D7S486 and D7S2460 microsatellite loci, which contains several candidate genes (TSG) such as TES, CAV2, CAV1, MET, CAPZA2, ST7 WNT2. We tested 41 human sporadic tumors for by using 5 polymorphic markers overlapping critical used a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay to study expression 7 TSGs located this genomic region. MET TES mRNA was lower than normal tissues. Our immunohistochemical results published data compartmental these messenger RNAs stromal epithelial cells suggest best gene 7q31. © 2004 Wiley-Liss, Inc.
