High MYC mRNA expression is more clinically relevant than MYC DNA amplification in triple-negative breast cancer [PDF]

open access: yes, 2019
DNA abnormalities are used in inclusion criteria of clinical trials for treatments with specific targeted molecules. MYC is one of the most powerful oncogenes and is known to be associated with triple-negative breast cancer (TNBC).

Extensive Gene Amplification as a Mechanism for Piperacillin-Tazobactam Resistance in Escherichia coli

open access: yesmBio, 2018
Although the TEM-1 β-lactamase (BlaTEM-1) hydrolyzes penicillins and narrow-spectrum cephalosporins, organisms expressing this enzyme are typically susceptible to β-lactam/β-lactamase inhibitor combinations such as piperacillin-tazobactam (TZP). However,

CATMA : a complete Arabidopsis GST database [PDF]

open access: yes, 2003
The Complete Arabidopsis Transcriptome Micro Array (CATMA) database contains gene sequence tag (GST) and gene model sequences for over 70% of the predicted genes in the Arabidopsis thaliana genome as well as primer sequences for GST amplification and a ...

High-Resolution Mapping of Genomic Imbalance and Identification of Gene Expression Profiles Associated with Differential Chemotherapy Response in Serous Epithelial Ovarian Cancer

open access: yesNeoplasia: An International Journal for Oncology Research, 2005
Array comparative genomic hybridization (aCGH) and microarray expression profiling were used to subclassify DNA and RNA alterations associated with differential response to chemotherapy in ovarian cancer.

c-Myc-Induced Extrachromosomal Elements Carry Active Chromatin

open access: yesNeoplasia: An International Journal for Oncology Research, 2003
Murine Pre-13 lymphocytes with experimentally activated MycER show both chromosomal and extrachromosomal gene amplification. In this report, we have elucidated the size, structure, functional components of c-Myc-induced extrachromosomal elements (EEs ...

XDJ1, a gene encoding a novel non-essential DnaJ homologue from Saccharomyces cerevisiae [PDF]

open access: yes, 1994
The gene encoding a novel DnaJ-like protein, termed Xdj1, has been identified by amplification of Saccharomyces cerevisiae genomic DNA. An open reading frame of 1380 bp was detected. Disruption of XDJ1 did not yield any detectable new phenotype. A double-

Assessment of Cyclin E Gene Amplification as a Biomarker in Isfahan Province Breast Cancer Patients [PDF]

open access: yesJournal of Advanced Biomedical Sciences, 2020
Background & Objective: Breast cancer is the most common cancer among women worldwide. Cell-cycle is controlled by regulatory proteins called cyclins and Cyclin-Dependent Kinases. Aberrant activity of cyclins plays an important role in cancer development

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]

open access: yes, 2019
Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Multiplex ligation-dependent probe amplification (MLPA) analysis is an effective tool for the detection of novel intragenic PLA2G6 mutations: Implications for molecular diagnosis [PDF]

open access: yes, 2010
Phospholipase associated neurodegeneration (PLAN) comprises a heterogeneous group of autosomal recessive neurological disorders caused by mutations in the PLA2G6 gene. Direct gene sequencing detects 85% mutations in infantile neuroaxonal dystrophy.

Guidelines for DNA recombination and repair studies: Cellular assays of DNA repair pathways

open access: yesMicrobial Cell, 2019
Understanding the plasticity of genomes has been greatly aided by assays for recombination, repair and mutagenesis. These assays have been developed in microbial systems that provide the advantages of genetic and molecular reporters that can readily be ...
