Frequent loss of heterozygosity on chromosome 9 in adenocarcinoma and squamous cell carcinoma of the esophagus.
Loss of heterozygosity (LOH) affecting chromosome 9p has been shown to occur frequently in head and neck cancer, glioma, mesothelioma, melanoma, lung cancer, and numerous other tumor types. Chromosome 9p is therefore presumed to contain a tumor suppressor gene or genes. Since esophageal cancer shares characteristics with some of the above tumor types, we performed a detailed examination of 60 p...
متن کاملFrequent loss of heterozygosity on chromosome 14q in neuroblastoma.
Using 29 polymorphic DNA markers which detect allelic deletion of genes at specific loci on 19 different chromosomes, we analyzed 14 neuroblastomas for possible loss of chromosomal heterozygosity. The incidence of loss of heterozygosity was high at the D14S1 locus on chromosome 14q, being detected in six of 12 patients (50%). In spite of the cytogenetic finding suggesting high frequency of chro...
متن کاملFrequent Loss of Heterozygosity at the Retinoblastoma
Mice bearing retinoblastoma susceptibility gene (RB) germ-line muta tions almost invariably develop pituitary neoplasms. We therefore tested 17 patients with pituitary tumors for loss of heterozygosity (LOH) using an RB sequence polymorphism and 5 polymorphic microsatellite markers surrounding the RB gene on the long arm of chromosome 13. In all of the 13 malignant or highly invasive pituitary ...
متن کاملLoss of heterozygosity at chromosome 9p21 is a frequent finding in enteropathy-type T-cell lymphoma.
Enteropathy-type T-cell lymphoma (ETL) and ulcerative jejunitis (UJ) are rare disorders often occurring in patients with coeliac disease. The genetic events associated with the accumulation of intraepithelial lymphocytes in coeliac disease and tumour development are largely unknown. Deletions at chromosome 9p21, which harbours the tumour suppressor genes p14/ARF, p15/INK4b, and p16/INK4a, and 1...
متن کاملFrequent loss of heterozygosity at chromosome 3p14.2-3p21 in human pancreatic islet cell tumours.
OBJECTIVE Pancreatic islet betacell tumours occur either sporadically or as part of inherited neoplastic syndromes, most commonly multiple endocrine neoplasia (MEN) type 1. Recently, a transgenic mouse model has been established in which the expression of the SV40 large T antigen was targeted to betacells by the rat insulin promoter, leading to the development of multiple pancreatic betacell tu...
