A new view of RNA: the 1989 discovery by Sidney Altman and Thomas Cech [PDF]

The Ukrainian Biochemical Journal, 2020
The 1989 Nobel Prize Laureates in Chemistry Sidney Altman and Thomas Robert Cech made one of the most important discoveries in molecular genetics. Independently of each other, they demonstra­ted new experimental evidence that RNA molecules can not only ...

Minigene Splicing Assays Identify 12 Spliceogenic Variants of BRCA2 Exons 14 and 15

Frontiers in Genetics, 2019
A relevant fraction of BRCA2 variants is associated with splicing alterations and with an increased risk of hereditary breast and ovarian cancer (HBOC). In this work, we have carried out a thorough study of variants from BRCA2 exons 14 and 15 reported at

CiLiQuant: Quantification of RNA Junction Reads Based on Their Circular or Linear Transcript Origin

Frontiers in Bioinformatics, 2022
Distinguishing circular RNA reads from reads derived from the linear host transcript is a challenging task because of sequence overlap. We developed a computational approach, CiLiQuant, that determines the relative circular and linear abundance of ...

Quantification of pre-mRNA escape rate and synergy in splicing [PDF]

, 2014
Splicing reactions generally combine high speed with accuracy. However, some of the pre-mRNAs escape the nucleus with a retained intron. Intron retention can control gene expression and increase proteome diversity.

Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Introns: the “dark matter” of the eukaryotic genome

Frontiers in Genetics, 2023
The emergence of introns was a significant evolutionary leap that is a major distinguishing feature between prokaryotic and eukaryotic genomes. While historically introns were regarded merely as the sequences that are removed to produce spliced ...

Multiple tandem splicing silencer elements suppress aberrant splicing within the long exon 26 of the human Apolipoprotein B gene. [PDF]

, 2013
: BACKGROUND: Apolipoprotein B (APOB) is an integral component of the chylomicron and the atherogenic lipoproteins LDL and Lp(a). Exon 26 of the APOB pre-mRNA is unusually long at 7,572 nt and is constitutively spliced.

Promoter-Bound Full-Length Intronic Circular RNAs-RNA Polymerase II Complexes Regulate Gene Expression in the Human Parasite Entamoeba histolytica

Non-Coding RNA, 2022
Ubiquitous eukaryotic non-coding circular RNAs are involved in numerous co- and post-transcriptional regulatory mechanisms. Recently, we reported full-length intronic circular RNAs (flicRNAs) in Entamoeba histolytica, with 3′ss–5′ss ligation points and 5′
