Recent studies have demonstrated the presence of microsatellite instability (MSI) in tumors from patients with hereditary nonpolyposis colon cancer and in a subset of patients with sporadic colorectal cancer (CRC). In sporadic CRC, three tumor phenotypes have been defined: microsatellite stable (MSS), low-frequency MSI, and high-frequency MSI (MSI-H).(More)
The RNASEL gene on chromosome 1q25 was recently identified as a candidate gene for hereditary prostate cancer (PC). To confirm these findings, we screened 326 patients from 163 families with familial PC for potential germline mutations, by use of conformation-sensitive gel electrophoresis, followed by direct sequence analysis. A total of six variants were(More)
A comprehensive analysis of somatic and germline mutations related to DNA mismatch-repair (MMR) genes can clarify the prevalence and mechanism of inactivation in colorectal carcinoma (CRC). In the present study, 257 unselected patients referred for CRC resection were examined for evidence of defective DNA MMR. In particular, we sought to determine the(More)
Microsatellite instability (MSI) is a genomic alteration observed in 15-30% of colorectal cancer (CRC). Two MSI phenotypes have been defined for CRC: MSI-H is characterized by MSI at > or =30% of the examined loci and MSI-L by MSI at 1-30% of the loci. An absence of MSI at any examined loci has been defined as a microsatellite stable (MSS) phenotype.(More)
BACKGROUND Circulating testosterone plays an important role in maintenance and growth of prostate cells. Luteinizing hormone (LH), secreted from the anterior pituitary, signals testicular Leydig cells to secrete testosterone. A genetic variant of the LH-beta protein, LH-betaV, exists in up to 40% of Caucasians and is more bioactive than the wild-type(More)
Two microsatellite instability (MSI) phenotypes have been described in colorectal cancer (CRC): MSI-H (instability at >30% of the loci examined) and MSI-L (MSI at 1-30% of the loci examined). The MSI-H phenotype, observed in both hereditary nonpolyposis colon cancer-associated CRC and approximately 15% of sporadic CRC, generally results from mutational or(More)
We have developed a three-color cytoplasmic immunoglobulin (cIg) and fluorescence in situ hybridization (FISH) technique to detect plasma cell chromosomal aneuploidy in patients with multiple myeloma (MM), monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and amyloidosis (AL). Immunofluorescent-labeled antibodies(More)
Physiological responses to exercise in dry heat were compared between six active men [maximum O2 consumption (VO2max), 51.4 +/- 1.2 ml . kg-1 . min-1] and four active women (VO2max, 47.2 +/- 1.3 ml . kg-1 . min-1) before, during, and after heat acclimatization. Subjects cycled a maximum of 2 h at 40% VO2max at 45 degrees C dry-bulb temperature, 23 degrees C(More)
