Post-transcriptional modifications of VEGF-A mRNA in non-ischemic dilated cardiomyopathy [PDF]
Cellular and Molecular Biology Letters, 2007 AbstractVascular endothelial growth factor (VEGF-A) is one of the most important proangiogenic factors. It has many isoforms encoded by one gene. The occurrence of these isoforms is associated with the process of alternative splicing of mRNA. Some of the splice forms are perceived as tissue specific.

International Journal of Molecular Sciences, 2023 Telomere length is associated with the proliferative potential of cells. Telomerase is an enzyme that elongates telomeres throughout the entire lifespan of an organism in stem cells, germ cells, and cells of constantly renewed tissues. It is activated during cellular division, including regeneration and immune responses.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Two-subunit enzymes involved in eukaryotic post-transcriptional tRNA modification [PDF]
RNA Biology, 2014 tRNA modifications are crucial for efficient and accurate protein translation, with defects often linked to disease. There are 7 cytoplasmic tRNA modifications in the yeast Saccharomyces cerevisiae that are formed by an enzyme consisting of a catalytic subunit and an auxiliary protein, 5 of which require only a single subunit in bacteria, and 2 of ...

Transcriptional control: Repression by local chromatin modification [PDF]
, 1998 It is becoming increasingly clear that chromatin modification plays a fundamental part in transcriptional control. Recent studies provide new insights into how transcriptional repressors, in addition to blocking activators, may recruit repression ...

FEBS Letters, EarlyView.Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Guide snoRNAs: Drivers or Passengers in Human Disease?
Biology, 2018 In every domain of life, RNA-protein interactions play a significant role in co- and post-transcriptional modifications and mRNA translation. RNA performs diverse roles inside the cell, and therefore any aberrancy in their function can cause various ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Post-transcriptional modifications and regulation of mRNAs in human mitochondria
BiochimieMitochondria contain their own circular genome (mtDNA), which encodes essential components of the oxidative phosphorylation (OXPHOS) system. Mitochondrial DNA transcription is a unique and relatively simple process, requiring a specialized transcription machinery that consists of a RNA polymerase (POLRMT), two transcription factors (TFAM and TFB2M ...

Structural landscape of base pairs containing post-transcriptional modifications in RNA [PDF]
RNA, 2017 Base pairs involving post-transcriptionally modified nucleobases are believed to play important roles in a wide variety of functional RNAs. Here we present our attempts toward understanding the structural and functional role of naturally occurring modified base pairs using a combination of X-ray crystal structure database analysis, sequence analysis ...
