Ruilin Zhang et al.
Recognition of double-stranded (ds) RNA is central to antiviral defense, yet how RNA sensors are activated during infection remains unclear. Here, we demonstrate that during vaccinia virus (VacV) infection, PKR binding is enriched on viral ...
Recruitment of Cas3 enables DNA cleavage by the type I-A CRISPR-Cas system of Saccharolobus islandicus [0.03%]
Cas3的招募可激活Saccharolobus islandicus I-A型CRISPR-Cas系统DNA切割活性

System consolidation transforms temporary hippocampal representation of memory into long-term storage in cortex. The underlying neural substrate, however, remains enigmatic. Here, we tracked the spatiotemporal evolution of hippocampus (HPC)...
Hyodeoxycholic acid suppresses hepatic steatosis in a PPARα-dependent manner via distinct GLP-1- and iNKT cell-mediated pathways [0.03%]
猪去氧胆酸通过不同的GLP-1和iNKT细胞介导的途径以PPARα依赖性方式抑制肝脂肪变性疾病
Eunyoung Lee,Ryo Hatano,Mariko Takami et al.
Eunyoung Lee et al.
Hepatosteatosis is a common metabolic disorder. Bile acids influence hepatosteatosis, immune function, and incretin secretion. However, whether bile acids mediate hepatosteatosis through these immune or endocrine pathways remain unknown. He...
Neocentromeres fail to maintain DNA methylation boundaries, driving CENP-A drift, instability, and chromosome missegregation [0.03%]
新的次中着丝粒无法维持DNA甲基化边界，导致CENP-A漂移、不稳定及染色体分离异常

Megan A Mahlke et al.
Centromere identity is specified by CENP-A, a histone H3 variant that epigenetically defines centromere position. How CENP-A is maintained at one location in rapidly evolving centromeric DNA is unknown. Using single-cell-derived clones of h...
Clustered inputs engage dendritic nonlinearities and calcium signaling to support efficient place-field formation in CA1 pyramidal neurons [0.03%]
