Stable centromere association of the yeast histone variant Cse4 requires its essential N-terminal domain.

Chromosome segregation relies on kinetochores that assemble on specialized centromeric chromatin containing a histone H3 variant. In budding yeast, a single centromeric nucleosome containing Cse4 assembles at a sequence-defined 125 bp centromere. Yeast centromeric sequences are poor templates for nucleosome formation in vitro, suggesting the existence of mechanisms that specifically stabilize Cse4 nucleosomes in vivo.

Probing mechanical selection in diverse eukaryotic genomes through accurate prediction of 3D DNA mechanics.

Connections between the mechanical properties of DNA and biological functions have been speculative due to the lack of methods to measure or predict DNA mechanics at scale. Recently, a proxy for DNA mechanics, cyclizability, was measured by loop-seq and enabled genome-scale investigation of DNA mechanics. Here, we use this dataset to build a computational model predicting bias-corrected intrinsic cyclizability, with near-perfect accuracy, solely based on DNA sequence.

Model for Urgency for Liver Transplantation in Hepatocellular Carcinoma: A Practical Model to Prioritize Patients With Hepatocellular Carcinoma on the Liver Transplant Waiting List.

Background & Aims: Currently, patients with hepatocellular carcinoma (HCC) in the United States are assigned a uniform score relative to the median Model for End-Stage Liver Disease (MELD) at transplant after a minimum 6-month waiting period. The authors developed a risk stratification model for patients with HCC using the available and objective variables at time of listing.

Methods: Adult liver transplant candidates with approved HCC exception in the Organ Procurement and Transplantation Network database from 2015-2022 were identified.

Sex Differences in Patient-Reported Outcomes and Perception of Ascites Burden Among Outpatients With Decompensated Cirrhosis and Ascites.

Introduction: Perception of the ascites burden and its effects on quality of life may be different between sexes. This study assessed sex differences in perception of ascites burden and its impact on health-related quality of life (HRQoL) in patients with recurrent or refractory ascites.

Methods: The North American Consortium for the Study of End-stage Liver Disease prospectively enrolled outpatients with cirrhosis and large ascites requiring repeat large volume paracenteses.
