In the title compound, C(20)H(32)N(2)O(2)S(2), the cyclo-hexene ring is disordered over two half-boat conformations with occupancy factors of 0.71:0.29. One n-butyl chain is also disordered over two positions with occupancy factors of 0.83:0.17. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond.

SPT5 exhibits versatile functions in RNA Pol II promoter proximal pausing, pause release, and elongation in metazoans. However, the mechanism underlying the functional switch of SPT5 during early elongation has not been fully understood. Here, we report that the phosphorylation site-rich domain (PRD)/CTR1 and the prion-like domain (PLD)/CTR2, which are situated adjacent to each other within the C-terminal repeat (CTR) in SPT5, play pivotal roles in Pol II pausing and elongation, respectively.

T cell activation is accompanied by extensive changes in epigenome. However, the high-ordered chromatin organization underpinning CD8 T cell activation is not fully known. Here, we show extensive changes in the three-dimensional genome during CD8 T cell activation, associated with changes in gene transcription.

Sex differences in the murine HPA axis after acute and repeated restraint stress.

Stress

Department of Preclinical Fluid Biomarkers & Occupancy, H. Lundbeck A/S, Valby, Denmark.

Chronic stress and stress-related mental illnesses such as major depressive disorder (MDD) constitute some of the leading causes of disability worldwide with a higher prevalence in women compared to men. However, preclinical research into stress and MDD is heavily biased toward using male animals only. Aberrant activity of the hypothalamic-pituitary-adrenal (HPA) axis has been linked to the development of MDD and several animal models of MDD have been established based on HPA axis dysregulation.

The Pd-Zn γ-brass phase provides exciting opportunities for synthesizing site-isolated catalysts with precisely controlled Pd active site ensembles. Introducing a third metallic element into the γ-brass lattice further perturbs the catalytic active site ensembles. Here, we introduce coinage metallic elements M (M = Cu, Ag, and Au) into the Pd-Zn γ-brass phase and investigate the site occupation factors of each element in the γ-brass lattice.

Gene expression is regulated by chromatin DNA methylation and other features, including histone post-translational modifications (PTMs), chromatin remodelers and transcription factor occupancy. A complete understanding of gene regulation will require the mapping of these chromatin features in small cell number samples. Here we describe a novel genome-wide chromatin profiling technology, named as Nicking Enzyme Epitope targeted DNA sequencing (NEED-seq).
