Hepatocellular carcinoma: Review of disease and tumor biomarkers. [PDF]

open access: yes, 2016
© The Author(s) 2016.Hepatocellular carcinoma (HCC) is a common malignancy and now the second commonest global cause of cancer death. HCC tumorigenesis is relatively silent and patients experience late symptomatic presentation. As the option for curative

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Glyco-7 alpha, 12 alpha-dihydroxy-5 beta-cholanic acid as internal standard for high-pressure liquid chromatographic analysis of conjugated bile acids.

open access: yesJournal of Lipid Research, 1985
Glyco-7 alpha, 12 alpha-dihydroxy-5 beta-cholanic acid was tested as internal standard for high-pressure liquid chromatographic analysis of the five main glycine- and taurine-conjugated bile acids present in adult human serum and bile.

Linkages in thermal copolymers of lysine [PDF]

open access: yes
The thermal copolymerization of lysine with other alpha-amino acids was studied. The identity of the second amino acid influences various properties of the polymer obtained, including the proportion of alpha and epsilon linkages of lysine.

Molecular Characterization of Thyroid Hormone Receptors (TRs) and their Responsiveness to T3 in Microhyla fissipes [PDF]

open access: yes, 2018
To explore and enrich the molecular mechanisms of thyroid hormone receptors (TRs) in the metamorphosis of amphibians, the cDNA sequences of TR alpha and TR beta in Microhyla fissipes were cloned and characterized.

Alpha-Linolenic Acid [PDF]

open access: yesCirculation, 2005
Although the fish-derived, long-chain omega-3 fatty acids (n-3 FA) may be considered “gifts from the sea” for cardiovascular health, the role of the land (or plant) -based n-3 FA α-linolenic acid (ALA) has been less clear. ALA is the 18-carbon, 3-double bond (C18:3n-3) precursor to eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Biosynthesis of hydroxyl-linked glucuronides of short-chain bile acids by rat liver 3-hydroxysteroid UDP-glucuronosyltransferase.

open access: yesJournal of Lipid Research, 1988
Microsomal preparations from livers of Sprague-Dawley rats catalyze the glucuronidation of 3 alpha-hydroxy-5 beta-H (3 alpha, 5 beta) short-chain bile acids (C20-C23), predominantly at the hydroxyl group, while the glucuronidation of 3 beta, 5 beta short-

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Lipids at the crossroad of α-synuclein function and dysfunction: Biological and pathological implications [PDF]

open access: yes, 2019
Since its discovery, the study of the biological role ofα-synuclein and its pathologicalimplications has been the subject of increasing interest. The propensity to adoptdifferent conformational states governing its aggregation and fibrillation makes ...
