Comparison of Intron-Dependent and Intron-Independent Gene Expression [PDF]

open access: yesMolecular and Cellular Biology, 1988
Recombinant simian virus 40 viruses carrying rabbit beta-globin cDNA failed to express the beta-globin sequence unless an intron was included in the transcription unit. The addition of either beta-globin IVS1 or IVS2 caused a 400-fold increase in RNA production.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Distribution of introns in fungal histone genes. [PDF]

open access: yesPLoS ONE, 2011
Saccharomycotina and Taphrinomycotina lack intron in their histone genes, except for an intron in one of histone H4 genes of Yarrowia lipolytica. On the other hand, Basidiomycota and Perizomycotina have introns in their histone genes.

Durable B‐Cell Impairment While Sparing IgA B Cells After Ocrelizumab Therapy in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Ocrelizumab (OCR), a humanized anti‐CD20 monoclonal antibody, is highly efficient in relapsing–remitting multiple sclerosis (RR‐MS). We assessed early cellular B‐cell profiles in patients prior to OCR treatment, on OCR treatment, and after 15 months of therapy discontinuation.

Non-coding parts of genomes as the basis of epigenetic heredity

open access: yesВавиловский журнал генетики и селекции, 2017
We hypothesized that the basis of epigenetic regulation of genomes in ontogenesis is the specificity of the distribution, number and composition of transposons. Transposons constitute the major part of the genomes of multicellular eukaryotes.

Plasma Glial Fibrillary Acidic Protein Correlates With Brain Metal Burden in Wilson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuroinflammation driven by extracellular copper contributes to neuronal damage in Wilson's disease (WD). This study investigated the relationship between brain metal burden and peripheral neuroinflammation markers in WD. Methods We conducted a cross‐sectional study involving 89 participants, including patients with WD (n = 63 ...

The origin of introns and their role in eukaryogenesis: a compromise solution to the introns-early versus introns-late debate?

open access: yesBiology Direct, 2006
Background Ever since the discovery of 'genes in pieces' and mRNA splicing in eukaryotes, origin and evolution of spliceosomal introns have been considered within the conceptual framework of the 'introns early' versus 'introns late' debate.

Functional Characterization and Pathogenicity Classification of PRRT2 Splice Variants in PRRT2‐Related Disorders

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Paroxysmal kinesigenic dyskinesia (PKD) is the most common hereditary paroxysmal movement disorder. The PRRT2 gene is the first identified causative gene and accounts for the majority of PKD. In this study, we investigated the pathogenicity of PRRT2 variants in the splice regions. Methods Patients with clinically suspected PKD and no

Evolutionary dynamics of U12-type spliceosomal introns

open access: yesBMC Evolutionary Biology, 2010
Background Many multicellular eukaryotes have two types of spliceosomes for the removal of introns from messenger RNA precursors. The major (U2) spliceosome processes the vast majority of introns, referred to as U2-type introns, while the minor (U12 ...

Presence of multiple group I introns closely related to bacteria and fungi in plastid 23S rRNAs of lichen-forming Trebouxia [PDF]

open access: yes, 2009
The chloroplast-encoded large subunit ribosomal RNA gene of several free-living green algae contains group I introns at Escherichia coli genic positions 1917, 1931, 1951, and 2449.
