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.

MET and NF2 alterations confer primary and early resistance to first‐line alectinib treatment in ALK‐positive non‐small‐cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

Long non‐coding RNAs as therapeutic targets in head and neck squamous cell carcinoma and clinical application

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

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.

The rise and falls of introns [PDF]

open access: yesHeredity, 2006
There has been a lively debate over the evolution of eukaryote introns: at what point in the tree of life did they appear and from where, and what has been their subsequent pattern of loss and gain? A diverse range of recent research papers is relevant to this debate, and it is timely to bring them together.

The role of circular RNAs in regulating cytokine signaling in cancer

open access: yesFEBS Open Bio, EarlyView.
Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...

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 ...

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.

Liver‐specific lncRNAs associated with liver cancers

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...

Evolution of the Exon-Intron Structure in Ciliate Genomes. [PDF]

open access: yesPLoS ONE, 2016
A typical eukaryotic gene is comprised of alternating stretches of regions, exons and introns, retained in and spliced out a mature mRNA, respectively.
