Cohesin residence time gates 3D genome response to histone hyperacetylation

Rebecca G. Smith, Kathleen L Schiela, Hannah M. Wilson, Ryan A Williams, James Johnson, Carson Cohen, Wei-Ting Yueh, Amy M. Whitaker, Neil Johnson, Masato T. Kanemaki, Yu Liu

This study shows that cohesin residence time, not just its presence, determines how histone hyperacetylation affects 3D genome structure.

Hyper-variability in Circulating Insulin and Physiological Outcomes in Male High Fat-fed Ins1-/-:Ins2+/- Mice in a Conventional Facility

Arya Mehran, Nicole M Templeman, Xiaoke Hu, James Johnson

This study examines insulin variability and physiological outcomes in male Ins1-/-:Ins2+/- mice on high fat diets, finding unexpected hyper-variability in circulating insulin levels and body weight changes.

Hyper-variability in Circulating Insulin Levels and Physiological Outcomes to High Fat Feeding in Male Ins1-/-:Ins2+/- Mice in a Specific Pathogen-free Facility

Nicole M Templeman, Arya Mehran, James Johnson

The paper examines insulin variability and physiological responses to high fat feeding in male Ins1-/-:Ins2+/- mice, finding inconsistent insulin levels and phenotypic outcomes across cohorts.
