The Mysterious World of Non‐Canonical Caps – What We Know and Why We Need New Sequencing Techniques

ChemBioChem, Volume 26, Issue 3, February 1, 2025.
This review describes sophisticated methodologies such as LC–MS that enabled the identification of 5’ non‐canonical RNA caps and also surveys so far developed sequencing methods, evaluating their advantages and disadvantages. It emphasizes the need for developing new, reliable sequencing techniques to identify RNA types with non‐canonical caps enabling

Tartary Buckwheat Bran and Fructus Aurantii Combination (TBB‐FA): A Promising Therapeutic Approach for Functional Dyspepsia via Modulation of Gut Microbiota, Short‐Chain Fatty Acids and Purine Signaling Pathway

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
Fructus aurantii, stir‐baked with Tartary buckwheat bran, was employed as a treatment for functional dyspepsia (FD). The potential of this combination to replace or supplement wheat bran was thoroughly assessed. The purinergic signaling system holds potential as a therapeutic target for gastrointestinal disorders, thereby facilitating the development ...

Nitrosative stress and pharmacological modulation of heart failure [PDF]

, 2005
Dysregulation of nitric oxide (NO) and increased oxidative and nitrosative stress are implicated in the pathogenesis of heart failure. Peroxynitrite is a reactive oxidant that is produced from the reaction of nitric oxide with superoxide anion and ...

Age‐related increase of CD38 directs osteoclastogenic potential of monocytic myeloid‐derived suppressor cells through mitochondrial dysfunction in male mice

Aging Cell, Volume 23, Issue 11, November 2024.
Aged M‐MDSCs have increased osteoclastogenesis potential. Transcriptomic analyses revealed the upregulation of mitochondrial oxidative phosphorylation and glucose metabolism genes, especially CD38 or NADase. A specific CD38 inhibitor reduced the mitochondrial oxygen consumption rate and glucose metabolism and inhibited the osteoclastogenic potential of

Neurological‐related proteomic profiling in plasma of children with metabolic healthy and unhealthy overweight/obesity

Pediatric Obesity, Volume 19, Issue 9, September 2024.
Summary Objective Children with overweight/obesity (OW/OB) exhibit poor cardiometabolic health, yet mechanisms influencing brain health remain unclear. We examined the differences in neurological‐related circulating proteins in plasma among children with metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) and the association ...

Impaired instructive and protective barrier functions of the endothelial cell glycocalyx pericellular matrix is impacted in COVID‐19 disease

Journal of Cellular and Molecular Medicine, Volume 28, Issue 16, August 2024.
Abstract The aim of this study was to review the roles of endothelial cells in normal tissue function and to show how COVID‐19 disease impacts on endothelial cell properties that lead to much of its associated symptomatology. This places the endothelial cell as a prominent cell type to target therapeutically in the treatment of this disorder.

Evolution of fungal tuberculosis necrotizing toxin (TNT) domain‐containing enzymes reveals divergent adaptations to enhance NAD cleavage

Protein Science, Volume 33, Issue 7, July 2024.
Abstract Tuberculosis necrotizing toxin (TNT) is a protein domain discovered on the outer membrane of Mycobacterium tuberculosis (Mtb), and the fungal pathogen Aspergillus fumigatus. TNT domains have pure NAD(P) hydrolytic activity, setting them apart from other NAD‐cleaving domains such as ADP‐ribosyl cyclase and Toll/interleukin‐1 receptor homology ...

Exploring NAD(+) metabolism in host-pathogen interactions [PDF]

, 2016
Nicotinamide adenine dinucleotide (NAD+) is a vital molecule found in all living cells. NAD+ intracellular levels are dictated by its synthesis, using the de novo and/or salvage pathway, and through its catabolic use as co-enzyme or co-substrate.
