Bacterial group I introns: mobile RNA catalysts

open access: yesMobile DNA, 2014
Group I introns are intervening sequences that have invaded tRNA, rRNA and protein coding genes in bacteria and their phages. The ability of group I introns to self-splice from their host transcripts, by acting as ribozymes, potentially renders their ...

Calcium Imparts Advanced Functionalities to Silk Hydrogels for Biofabrication and Biomedical Innovation

open access: yesAdvanced Functional Materials, EarlyView.
The addition of calcium ions to silk fibroin enhances the hydrogel properties and, when combined with visible light crosslinking, enables compatibility with advanced light‐based fabrication techniques. Calcium ions extend the shelf‐life of silk and facilitate the fabrication of multizonal, multilayered constructs for advanced stimuli‐responsive ...

The Cancer Spliceome: Reprograming of Alternative Splicing in Cancer

open access: yesFrontiers in Molecular Biosciences, 2018
Alternative splicing allows for the expression of multiple RNA and protein isoforms from one gene, making it a major contributor to transcriptome and proteome diversification in eukaryotes.

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.

Genome wide comparative analysis of the effects of PRMT5 and PRMT4/CARM1 arginine methyltransferases on the Arabidopsis thaliana transcriptome [PDF]

open access: yes, 2015
BACKGROUND: Methylation at arginine residues (R) is an important post-translational modification that regulates a myriad of essential cellular processes in eukaryotes, such as transcriptional regulation, RNA processing, signal transduction and DNA repair.

Conservation in first introns is positively associated with the number of exons within genes and the presence of regulatory epigenetic signals

open access: yesBMC Genomics, 2014
BackgroundGenomes of higher eukaryotes have surprisingly long first introns and in some cases, the first introns have been shown to have higher conservation relative to other introns.

Photosensitizing Lipid Nanoparticles for Ferroptosis‐Enhanced Photodynamic Cancer Therapy via GPX4 Silencing

open access: yesAdvanced Healthcare Materials, EarlyView.
Photosensitizing lipid nanoparticles (PLNPs) are engineered by incorporating cholesterol–PEG–pheophorbide a into MC3‐based LNPs and encapsulating GPX4‐targeting siRNA. Upon light activation, PLNPs generate reactive oxygen species (ROS) while silencing GPX4 to induce ferroptosis.

Horizontal Transfer and Gene Conversion as an Important Driving Force in Shaping the Landscape of Mitochondrial Introns

open access: yesG3: Genes, Genomes, Genetics, 2014
Group I introns are highly dynamic and mobile, featuring extensive presence-absence variation and widespread horizontal transfer. Group I introns can invade intron-lacking alleles via intron homing powered by their own encoded homing endonuclease gene ...

Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials

open access: yesAdvanced Materials, EarlyView.
This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,

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.
