Amphiphilic Polypeptides Obtained by Post-Polymerization Modification of Poly-l-Lysine as Systems for Combined Delivery of Paclitaxel and siRNA

open access: yesPharmaceutics, 2023
The development of effective anti-cancer therapeutics remains one of the current pharmaceutical challenges. The joint delivery of chemotherapeutic agents and biopharmaceuticals is a cutting-edge approach to creating therapeutic agents of enhanced ...

RNA methyltransferases involved in 5′ cap biosynthesis [PDF]

open access: yesRNA Biology, 2014
In eukaryotes and viruses that infect them, the 5' end of mRNA molecules, and also many other functionally important RNAs, are modified to form a so-called cap structure that is important for interactions of these RNAs with many nuclear and cytoplasmic proteins.

Potential Drugs Targeting Early Innate Immune Evasion of SARS-Coronavirus 2 via 2’-O-Methylation of Viral RNA

open access: yesViruses, 2020
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causing the COVID-19 respiratory disease pandemic utilizes unique 2′-O-methyltransferase (2′-O-MTase) capping machinery to camouflage its RNA from innate immune recognition.

Deciphering the RNA capping process in bacteria [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
RNA capping in eukaryotes has been studied since the 1970s, starting with the discovery of 5′ 7-methylguanylate caps in the Shatkin laboratory (1). That capping mechanism involves a pause during transcription elongation that allows the recruitment of specialized capping enzymes to modify the 5′ end of the nascent RNA.

Extensive 5′-surveillance guards against non-canonical NAD-caps of nuclear mRNAs in yeast

open access: yesNature Communications, 2020
NAD (nicotinamide adenine dinucleotide) acts as a non-canonical RNA cap structure in bacteria and eukaryotes. Here the authors demonstrate the whole landscape of budding yeast NAD-RNAs which are subject to diverse surveillance pathways, suggesting that ...

METTL1 drives tumor progression of bladder cancer via degrading ATF3 mRNA in an m7G-modified miR-760-dependent manner

open access: yesCell Death Discovery, 2022
7-methylguanosine (m7G) modification is recently found to conservatively exist in RNA internal position besides mRNA caps and mediates the various RNA metabolisms.

RNA capping by mitochondrial and multi-subunit RNA polymerases [PDF]

open access: yesTranscription, 2018
Recently, it was found that bacterial and eukaryotic transcripts are capped with cellular cofactors installed by their respective RNA polymerases (RNAPs) during transcription initiation. We now show that mitochondrial RNAP efficiently caps transcripts with ADP - containing cofactors.

RNA capping: progress and prospects [PDF]

open access: yesRNA, 2015
The 5′ m7GpppN cap, co-discovered by Shatkin, Furuichi, and Moss in 1975, is the signature feature of eukaryal cellular and viral messenger RNA that confers mRNA stability and efficient translation. Cap formation entails three sequential enzymatic modifications targeted to nascent pre-mRNAs synthesized by cellular or viral RNA polymerases. First, the 5′

Revealing the Pathogenesis of Salt-Sensitive Hypertension in Dahl Salt-Sensitive Rats through Integrated Multi-Omics Analysis

open access: yesMetabolites, 2022
Salt-induced renal metabolism dysfunction is an important mechanism of salt-sensitive hypertension. Given that the gut-liver axis is the first hit of a high-salt diet (HSD), we aimed to identify the extra-renal mechanism from hepatic metabolism and gut ...

Helix Capping in RNA Structure

open access: yesPLoS ONE, 2014
Helices are an essential element in defining the three-dimensional architecture of structured RNAs. While internal basepairs in a canonical helix stack on both sides, the ends of the helix stack on only one side and are exposed to the loop side, thus susceptible to fraying unless they are protected.
