Genetic coupling of enhancer activity and connectivity in gene expression control.

Gene enhancers often form long-range contacts with promoters, but it remains unclear if the activity of enhancers and their chromosomal contacts are mediated by the same DNA sequences and recruited factors. Here, we study the effects of expression quantitative trait loci (eQTLs) on enhancer activity and promoter contacts in primary monocytes isolated from 34 male individuals. Using eQTL-Capture Hi-C and a Bayesian approach considering both intra- and inter-individual variation, we initially detect 19 eQTLs associated with enhancer-eGene promoter contacts, most of which also associate with enhancer accessibility and activity.

Modeling the Health and Economic Impact of Pharmacologic Therapies for MASLD in the United States.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common condition leading to chronic liver disease which generates substantial health care costs. Our aim was to model the impact on disease and economic burden of a hypothetical pharmacologic therapy which halts MASLD fibrosis progression.

Methods: The U.

Phosphorylated-tau associates with HSV-1 chromatin and correlates with nuclear speckles decondensation in low-density host chromatin regions.

Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.

Diastereoselective β-hydroxy vinylsulfone isomerizations.

Vinylic phenylsulfones containing a β-hydroxyl stereocenter undergo a diastereoselective isomerization to the corresponding allylic isomer upon treatment with 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU).
