LOH analysis on 4q in sporadic colorectal carcinoma
... chain reaction (PCR). PCR products were eletrophoresed on an ABI 377 DNA sequencer. Genescan 3.7 and Genotype 3.7 software were used for loss of heterozygosity
(LOH) scanning and analysis. Compared with clinicopathological features, significant relationship was observed between LOH frequencies on D4S3018 ...
New Diagnostic Tool Uncovered Gene Expression Patterns in Recessive Genetic Disorders
... for three or four harmful recessive mutations, and if the expression levels of several hundred genes are altered for each of these mutations, then heterozygosity
for recessive mutations plays a significant role in human variation and in the overall genetic architecture of complex human traits and diseases,’ ...

Mate selection more biologically determined in some human populations
... be mediated by preferences based on body odor. Some previous studies have reported a tendency for humans to prefer MHC-dissimilar mates, encouraging heterozygosity
at MHC loci in offspring and resulting in improved immune response. However, other studies, both directly in couples and also indirectly in "sweaty ...
Plant geneticists find veritas in vino
... to that of rice or poplar trees and much smaller than that of wheat or maize. Nevertheless, sequencing the genome was complicated by the degree of heterozygosity
between pairs of chromosomes, some 11.2% of the sequence differing between homologous regions. There was so much variation, in fact, that Velasco ...
Evolutionary conservation of a mechanism of longevity from worms to mammals
... genetic backgrounds tested. Moreover, when the livers of these mice where analyzed, the authors found that a subset of hepatocytes exhibited loss of heterozygosity
(effectively becoming mclk1-/- cells) and had undergone clonal expansion. The authors suggest that these mclk null cells were able to out-compete ...
Customized gene chip provides rapid detection of genetic changes in children's cancer
... researchers have pinpointed specific genetic abnormalities that influence the aggressiveness of neuroblastoma. An important abnormality is loss of heterozygosity
(LOH), the deletion of one copy of a pair of genes. When the gene involved is a tumor suppressor gene, LOH removes a brake on uncontrolled cell ...
