Sex determining region Y-box 2 (SOX2) amplification is an independent indicator of disease recurrence in sinonasal cancer. [PDF]

open access: yes, 2013
The transcription factor SOX2 (3q26.3-q27) is an embryonic stem cell factor contributing to the induction of pluripotency in terminally differentiated somatic cells.

Gene Amplification in Tumor Cells: Developed De Novo or Adopted from Stem Cells

open access: yesCells, 2022
Gene amplifications have been known for several decades as physiological processes in amphibian and flies, e.g., during eggshell development in Drosophila and as part of pathological processes in humans, specifically in tumors and drug-resistant cells ...

Mechanisms of IS26-Mediated Amplification of the aphA1 Gene Leading to Tobramycin Resistance in an Acinetobacter baumannii Isolate

open access: yesMicrobiology Spectrum, 2022
Enhanced levels of resistance to antibiotics arising from amplification of an antibiotic resistance gene that impact therapeutic options are increasingly observed. Amplification can also disclose novel phenotypes leading to treatment failure.

Chromothripsis drives the evolution of gene amplification in cancer

open access: yesNature, 2020
Focal chromosomal amplification contributes to the initiation of cancer by mediating overexpression of oncogenes1–3, and to the development of cancer therapy resistance by increasing the expression of genes whose action diminishes the efficacy of anti ...

Induction of Gene Amplification Contribute to Sulfonamide Resistance in Proteus mirabilis [PDF]

open access: yesمجلة التربية والعلم, 2007
Thirty Isolates of Proteus mirabilis from different clinical sources (Urine, Bum, Ear, and Wounds) were recovered. All isolates were subjected to the series of confirming tests to insure that these isolates are Proteus mirabilis, which identified ...

Gene Amplification

open access: yesDefinitions, 2020
Gene amplification is an increase in the number of copies of a gene sequence. Cancer cells sometimes produce multiple copies of genes in response to signals from other cells or their environment. The term also can refer to polymerase chain reaction (PCR),

Viral load could be an important determinant for fomites based transmission of viral infections

open access: yesJournal of Family Medicine and Primary Care, 2021
Background and Objective: Fomites are common sources of transmission of certain infections. Infectious pathogens, such as viruses known to cause respiratory tract infections, are common examples of being transmitted by fomites.

Genomic and phenotypic evolution of Escherichia coli in a novel citrate-only resource environment

open access: yeseLife, 2020
Evolutionary innovations allow populations to colonize new ecological niches. We previously reported that aerobic growth on citrate (Cit+) evolved in an Escherichia coli population during adaptation to a minimal glucose medium containing citrate (DM25 ...

Developmentally Programmed Switches in DNA Replication: Gene Amplification and Genome-Wide Endoreplication in Tetrahymena

open access: yesMicroorganisms, 2023
Locus-specific gene amplification and genome-wide endoreplication generate the elevated copy number of ribosomal DNA (rDNA, 9000 C) and non-rDNA (90 C) chromosomes in the developing macronucleus of Tetrahymena thermophila.
