Targeting tumor vulnerabilities associated with loss of heterozygosity

Molecular & Cellular Oncology, 2020
We show that N-acetyltransferase 2 (NAT2) loss of heterozygosity can be targeted in >4% of colorectal cancers with the use of a small molecule. We identify and describe the effect of a compound that impairs the growth of colorectal tumors with slow NAT2 ...

Molecular clonality analysis of esophageal adenocarcinoma by multiregion sequencing of tumor samples

BMC Research Notes, 2017
Background Intratumor heterogeneity has been demonstrated in several cancer types, following a model of branched evolution. It is unknown to which extent intratumor heterogeneity is applicable to esophageal adenocarcinoma. Therefore the aim of this study

Molecular and clinicopathological analysis of three cases of gastric juvenile polyposis

JGH Open, 2022
Background and Aim Juvenile polyposis (JP) is a rare disease known to be associated with mutations either in SMAD4/BMPR1A. JP is known to often develop into malignant tumors, with a reported probability of 9–50%.

High incidence of microsatellite instability and loss of heterozygosity in three loci in breast cancer patients receiving chemotherapy: a prospective study

BMC Cancer, 2012
Background The aim of the study was to evaluate potential chemotherapy-induced microsatellite instability, loss of heterozygosity, loss of expression in mismatch repair proteins and associations with clinical findings in breast cancer patients ...

Loss of heterozygosity (LOH)--implications for human genetic identification.

Folia Histochemica et Cytobiologica, 2009
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 ...

The Genome of the Human Pathogen Candida albicans Is Shaped by Mutation and Cryptic Sexual Recombination

mBio, 2018
The opportunistic fungal pathogen Candida albicans lacks a conventional sexual program and is thought to evolve, at least primarily, through the clonal acquisition of genetic changes. Here, we performed an analysis of heterozygous diploid genomes from 21

Evaluation of Heterozygosity Loss in STR-Loci of Tumor DNA in Multiple Myeloma Patients with Plasmacytoma Based on the Molecular Analysis of Complex Archival Tumor Samples

Клиническая онкогематология, 2022
Background. Multiple myeloma (MM) is a hematological malignancy with plasma cells as substrate. Sometimes MM is characterized by plasmacytomas, i.e., intra- and extraosseous tumors.

Exploiting loss of heterozygosity for allele-selective colorectal cancer chemotherapy

Nature Communications, 2020
Allelic losses occurring in cancer cells have been suggested as potential targets for therapy. Here, the authors show how recurring loss of heterozygosity of a drug metabolic gene in colorectal cancers can be exploited using a low molecular weight ...

Value of the loss of heterozygosity to BRCA1 variant classification

npj Breast Cancer, 2022
At least 10% of the BRCA1/2 tests identify variants of uncertain significance (VUS) while the distinction between pathogenic variants (PV) and benign variants (BV) remains particularly challenging.
