Prognostic value of FLT3 mutations in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline monochemotherapy

open access: yesHaematologica, 2011
Background Fms-like tyrosine kinase-3 (FLT3) gene mutations are frequent in acute promyelocytic leukemia but their prognostic value is not well established.Design and Methods We evaluated FLT3-internal tandem duplication and FLT3-D835 mutations in ...

Characterization and evolution of microRNA genes derived from repetitive elements and duplication events in plants. [PDF]

open access: yesPLoS ONE, 2012
MicroRNAs (miRNAs) are a major class of small non-coding RNAs that act as negative regulators at the post-transcriptional level in animals and plants. In this study, all known miRNAs in four plant species (Arabidopsis thaliana, Populus trichocarpa, Oryza

The shape of human gene family phylogenies [PDF]

open access: yes, 2006
Background: The shape of phylogenetic trees has been used to make inferences about the evolutionary process by comparing the shapes of actual phylogenies with those expected under simple models of the speciation process. Previous studies have focused

Intron gain by tandem genomic duplication: a novel case in a potato gene encoding RNA-dependent RNA polymerase [PDF]

open access: yesPeerJ, 2016
The origin and subsequent accumulation of spliceosomal introns are prominent events in the evolution of eukaryotic gene structure. However, the mechanisms underlying intron gain remain unclear because there are few proven cases of recently gained introns.

Independent large scale duplications in multiple M. tuberculosis lineages overlapping the same genomic region [PDF]

open access: yes, 2012
Mycobacterium tuberculosis, the causative agent of most human tuberculosis, infects one third of the world's population and kills an estimated 1.7 million people a year. With the world-wide emergence of drug resistance, and the finding of more functional

A novel regimen for relapsed/refractory adult acute myeloid leukemia using a KMT2A partial tandem duplication targeted therapy: results of phase 1 study NCI 8485

open access: yesHaematologica, 2018
KMT2A partial tandem duplication occurs in approximately 5–10% of patients with acute myeloid leukemia and is associated with adverse prognosis. KMT2A wild type is epigenetically silenced in KMT2A partial tandem duplication; re-expression can be induced ...

Comparative Analysis Reveals Different Evolutionary Fates and Biological Functions in Wheat Duplicated Genes (Triticum aestivum L.)

open access: yesPlants, 2023
Wheat (Triticum aestivum L.) is a staple food crop that provides 20% of total human calorie consumption. Gene duplication has been considered to play an important role in evolution by providing new genetic resources.

STIL binding to Polo-box 3 of PLK4 regulates centriole duplication [PDF]

open access: yes, 2015
Polo-like kinases (PLK) are eukaryotic regulators of cell cycle progression, mitosis and cytokinesis; PLK4 is a master regulator of centriole duplication.

The Tandem Duplication Distance Is NP-Hard [PDF]

open access: yes, 2020
In computational biology, tandem duplication is an important biological phenomenon which can occur either at the genome or at the DNA level. A tandem duplication takes a copy of a genome segment and inserts it right after the segment - this can be ...
