Loss of heterozygosity (LOH)--implications for human genetic identification.
The aim of this study was assessment of possible effects of loss of heterozygosity on human genetic identification of histolopathogical tissue sections. DNA templates were extracted from tumour tissue specimens excised from oncological patients and from reference blood samples. AmpFlSTR Identifiler PCR Amplification Kit and ABI 310 Genetic Analyzer (Applera) were used to obtain genetic profiles...
متن کاملDissecting Loss of Heterozygosity (LOH) in Neurofibromatosis Type 1-Associated Neurofibromas: Importance of Copy Neutral LOH
Dermal neurofibromas (dNFs) are benign tumors of the peripheral nervous system typically associated with Neurofibromatosis type 1 (NF1) patients. Genes controlling the integrity of the DNA are likely to influence the number of neurofibromas developed because dNFs are caused by somatic mutational inactivation of the NF1 gene, frequently evidenced by loss of heterozygosity (LOH). We performed a c...
متن کاملLoss of heterozygosity (LOH) on chromosomes 2q, 3p and 21q in Indian oral squamous cell carcinoma.
Around the world, 200,000 people a year are affected by oral cancer, and the incidence of this disease is 10 times higher in India than Japan, mainly due to the custom of chewing tobacco. Loss of heterozygosity (LOH) on the long arm of chromosome 2 (2q), the short arm of chromosome 3 (3p) and the long arm of chromosome 21 (21q) are observed in several human cancers. We identified novel tumor su...
متن کاملGenetic mechanisms of TP53 loss of heterozygosity in Barrett's esophagus: implications for biomarker validation.
BACKGROUND AND AIMS 17p (TP53) loss of heterozygosity (LOH) has been reported to be predictive of progression from Barrett's esophagus to esophageal adenocarcinoma, but the mechanism by which TP53 LOH develops is unknown. It could be (a) DNA deletion, (b) LOH without copy number change, or (c) tetraploidy followed by genetic loss. If an alternative biomarker assay, such as fluorescence in situ ...
متن کاملCharacterization of the human Rad51 genomic locus and examination of tumors with 15q14-15 loss of heterozygosity (LOH).
Human Rad51 (hRad51) has been found to be associated with BRCA1, BRCA2, and p53 either directly or indirectly and is one of at least eight human genes that are members of the Escherichia coli RecA/Saccharomyces cerevisiae Rad51 family thought to affect genomic stability through DNA recombination/repair processes. While inactivation of DNA mismatch repair clearly leads to instability of repeated...
