Proximity to the Promoter and Terminator Regions Regulates the Transcription Enhancement Potential of an Intron

open access: yesFrontiers in Molecular Biosciences, 2021
An evolutionarily conserved feature of introns is their ability to enhance expression of genes that harbor them. Introns have been shown to regulate gene expression at the transcription and post-transcription level.

Constructive role of dissipation for driven coupled bosonic modes [PDF]

open access: yes, 2008
We describe four cases of childhood B-cell progenitor acute lymphoblastic leukaemia (BCP-ALL) and one of T-cell (T-ALL) with unexpected numbers of interphase signals for ETV6 with an ETV6-RUNX1 fusion probe.

Intron exclusion and the mystery of intron loss [PDF]

open access: yesFEBS Letters, 2006
Mechanisms for loss and gain of introns are elusive. Reported here is a new pattern of intron loss which features a random loss of a single intron in a multiple‐intron gene with its neighboring introns remained, which process is defined as intron exclusion.

Intron or no intron: a matter for nuclear pore complexes [PDF]

open access: yesNucleus, 2015
Nuclear pore complexes (NPCs) have been shown to regulate distinct steps of the gene expression process, from transcription to mRNA export. In particular, mRNAs expressed from intron-containing genes are surveyed by a specific NPC-dependent quality control pathway ensuring that unspliced mRNAs are retained within the nucleus.

The insertion of a mitochondrial selfish element into the nuclear genome and its consequences

open access: yesEcology and Evolution, 2020
Homing endonucleases (HE) are enzymes capable of cutting DNA at highly specific target sequences, the repair of the generated double‐strand break resulting in the insertion of the HE‐encoding gene (“homing” mechanism).

An overview of RNA splicing and functioning of splicing factors in land plant chloroplasts

open access: yesRNA Biology, 2022
RNA splicing refers to a process by which introns of a pre-mRNA are excised and the exons at both ends are joined together. Chloroplast introns are inherently self-splicing ribozymes, but over time, they have lost self-splicing ability due to the ...

A new targeted CFTR mutation panel based on next-generation sequencing technology [PDF]

open access: yes, 2017
Searching for mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR) is a key step in the diagnosis of and neonatal and carrier screening for cystic fibrosis (CF), and it has implications for prognosis and personalized therapy ...

The phylogeography of red and yellow coppersmith barbets (Aves: Megalaima haemacephala)

open access: yesFrontiers in Ecology and Evolution, 2014
Understanding the evolution of color in birds is important because it is used for both inter- and intra-specific communication and is often linked to other important traits including life history, behavior, immunology and mate choice.

The Globin Gene Family in Arthropods: Evolution and Functional Diversity

open access: yesFrontiers in Genetics, 2020
Globins are small heme-proteins that reversibly bind oxygen. Their most prominent roles in vertebrates are the transport and storage of O2 for oxidative energy metabolism, but recent research has suggested alternative, non-respiratory globin functions ...

Coevolution Theory of the Genetic Code at Age Forty: Pathway to Translation and Synthetic Life

open access: yesLife, 2016
The origins of the components of genetic coding are examined in the present study. Genetic information arose from replicator induction by metabolite in accordance with the metabolic expansion law.
