Nobel Prize recognizes scientists who laid groundwork for COVID-19 vaccines : Shots - Health News https://www.npr.org/1202941256

The 2023 Nobel Prize for Physiology or Medicine has been awarded to Hungarian-born Katalin Karikó and American Drew Weissman for work that enabled the development mRNA COVID-19 vaccines. Their work, undertaken at the University of Pennsylvania, made it possible to develop vaccines based on genetic material called messenger RNA. The scientists discovered that changing a chemical building block of mRNA – substituting pseudouridine for uridine — eliminated an inflammatory side effect that was a barrier to development of this new kind of vaccine. They published their work 15 years before the COVID pandemic.

Study of the #RNA splicing kinetics via in vivo 5-ethynyl uridine labelling [Article]

Splicing, a process of intron removal from eukaryotic RNA transcripts, is an important step of gene expression in all eukaryotes. Splice sites might be used with different efficiency giving rise to alternative splicing products. At the same time, splice sites might be utilised at a variable rate. We used 5-ethynyl uridine labelling to sequence a nascent transcriptome of HeLa cells and deduce the rate of splicing for each donor and acceptor splice site. The following correlation analysis allowed us to assess a correspondence of primary transcript features with the rate of splicing. Some dependencies we revealed were anticipated, such as splicing rate decrease with a decreased complementarity of donor splice site to U1 and acceptor sites to U2 snRNAs, or an acceleration of donor site usage if an upstream acceptor site is located at a shorter distance. Other dependencies were more surprising, like a negative influence of a distance to the 5' end on the rate of acceptor splicing site utilization, or the differences in splicing rate between long, short and RBM17-dependent introns. We also observed a deceleration of last intron splicing with an increase of the distance to the polyA site, which might be explained by a cooperativity of the splicing and polyadenylation. In addition, we performed the analysis of splicing kinetics of SF3B4 knockdown cells which suggested the impairment of U2 snRNA recognition step. As a result, we deconvoluted the effects of several examined features on the splicing rate into a single regression model. The data obtained here are useful for further studies in the field as it provides general splicing rate dependencies as well as helps justify the existence of slowly removed splice sites, e.g. to ensure alternative splicing. http://rnajournal.cshlp.org/cgi/content/short/rna.079937.123v1?rss=1&utm_source=dlvr.it&utm_medium=tumblr

Nucleotide synthesis involves various pathways and processes, with multiple chemical pathways contributing to the abiotic synthesis of nucleotides.

Abiotic Nucleotide Synthesis: Recent research has identified multiple chemical pathways for the abiotic synthesis of nucleotides, with mineral surfaces such https://urjamedicalfoundation.org/p2np-unveiled-exploring-the-chemical-landscape as clay minerals, zeolites, and hydroxides proposed as key participants in the origin of life by providing scaffolds for nucleotide synthesis

Pentose Phosphate Pathway: The synthesis of nucleotides requires a source of ribose 5-phosphate, which is produced from glucose 6-phosphate via the pentose phosphate pathway. This pathway not only produces ribose 5-phosphate but also serves as a major source of NADPH, a coenzyme required for anabolism and the repair of oxidative damage

Pyrimidine Synthesis: The synthesis of pyrimidine nucleotides, including cytidine, uridine, and thymidine, involves the formation of uridine from aspartate, glutamine, bicarbonate, and ATP molecules. This process requires PRPP to provide ribose-monophosphate, and the synthesis of uridine-monophosphate precedes the formation of uridine-triphosphate (UTP) and subsequent conversion to cytidine-triphosphate (CTP)

Regulation and Energy Intensity: Nucleotide synthesis is an energy-intensive process that uses multiple metabolic pathways across different cell compartments and several sources of carbon and nitrogen. It is regulated at the transcription level by master transcription factors and at the enzyme level by allosteric regulation and feedback inhibition. This regulation is particularly important during cell proliferation, where increased nucleotide synthesis is necessary for DNA replication and RNA production to support protein synthesis

Metabolomics unveiled the impact of alterations in nucleotide glucose metabolism on palmitic acid-induced TLR4 activation in THP-1 macrophages

Objective: The association of palmitic acid with macrophage inflammation and its promotion of the expression of inflammatory factors through TLR4 have been demonstrated. It has been observed that immature TLR4 localizes to the endoplasmic reticulum and Golgi apparatus, necessitating glycosylation for migration to the cell membrane. The objective of this study was to identify potential biomarkers associated with N-glycosylation subsequent to the activation of TLR4 inflammatory signaling in human macrophages by palmitic acid. Approach and Results: The co-cultivation of palmitic acid with THP-1 macrophages was conducted for a duration of 24 hours, followed by the collection of cell extracts for subsequent metabolomic and lipidomic analyses using high performance liquid chromatography-tandem mass spectrometry. Multivariate and univariate statistical analyses were conducted to identify potential biomarkers, in accordance with established scientific protocols. The impact of palmitic acid on the TLR4 signaling pathway and macrophage N-glycosylation was assessed at various time points using Western blot analysis, immunofluorescence staining, Elisa assays, and chemical labeling techniques. The TLR4 inflammatory signaling pathway was examined in macrophages at different time points, revealing that PA induced the upregulation of MyD88 and TRAF6 expression as well as NF-{kappa}B phosphorylation, indicating the activation of classical NF-{kappa}B signaling. After 24 hours, TLR4 translocated from the cell membrane to the cytoplasm and initiated internalization, accompanied by significant colocalization with GalAz in the cytosol. In addition, the metabolites in the cell extract were found to be altered in both the control and model groups. Significantly alterations in two N-glycosylation related metabolites were observed in the model group, including guanosine diphosphate-L-fucose and uridine diphosphate-N-acetylglucosamine/uridine diphosphate-N-acetylgalactosamine. Conclusion: THP-1 macrophages incubated with palmitic acid exhibited a distinct metabolomic profile compared to the control group. Our findings suggest that metabolomics analysis holds promise in identifying disease-specific biomarkers for diagnosing fatty acid-induced inflammatory responses in macrophages. http://dlvr.it/T0wF97
