Gene amplification and insecticide resistance
AbstractPesticide resistance in arthropods has been shown to evolve by two main mechanisms, the enhanced production of metabolic enzymes, which bind to and/or detoxify the pesticide, and mutation of the target protein, which makes it less sensitive to the pesticide.

Epigenetic regulation affects gene amplification in Drosophila development
In Drosophila melanogaster, in response to developmental transcription factors, and by repeated initiation of DNA replication of four chorion genes, ovarian follicle cells, form an onion skin-type structure at the replication origins. The DNA replication

A PCA3 gene-based transcriptional amplification system targeting primary prostate cancer. [PDF]
Targeting specifically primary prostate cancer (PCa) cells for immune therapy, gene therapy or molecular imaging is of high importance. The PCA3 long non-coding RNA is a unique PCa biomarker and oncogene that has been widely studied.

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

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

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

Prognostic stratification of adult primary glioblastoma multiforme patients based on their tumor gene amplification profiles [PDF]
[EN]everal classification systems have been proposed to address genomic heterogeneity of glioblastoma multiforme, but they either showed limited prognostic value and/or are difficult to implement in routine diagnostics.

The MDM2 gene amplification database [PDF]
The p53 tumor suppressor gene is inactivated in human tumors by several distinct mechanisms. The best characterized inactivation mechanisms are: (i) gene mutation; (ii) p53 protein association with viral proteins; (iii) p53 protein association with the MDM2 cellular oncoprotein. The MDM2 gene has been shown to be abnormally up-regulated in human tumors
