  摘要：Selective degradation of pathological protein aggregates while sparing monomeric forms is of major therapeutic interest. The E3 ligase tripartite motif-containing protein 21 (TRIM21) degrades antibody-bound proteins in an assembly state-specific manner due to the requirement of TRIM21 RING domain clustering for activation, yet effective targeting of intracellular assemblies remains challenging. Here, we fused the RING domain of TRIM21 to a target-specific nanobody to create intracellularly exp...

  摘要：Chromosome-containing micronuclei are a hallmark of aggressive cancers. Micronuclei frequently undergo irreversible collapse, exposing their enclosed chromatin to the cytosol. Micronuclear rupture catalyzes chromosomal rearrangements, epigenetic abnormalities, and inflammation, yet mechanisms safeguarding micronuclear integrity are poorly understood. In this study, we found that mitochondria-derived reactive oxygen species (ROS) disrupt micronuclei by promoting a noncanonical function of charg...

• Stereodivergent access to non-natural α-amino acids via enantio- and Z/E-selective catalysis AI翻译

  摘要：The precise control of Z and E configurations of the carbon-carbon double bond in alkene synthesis has long been a fundamental challenge in synthetic chemistry, even more pronounced when simultaneously striving to achieve enantioselectivity [(Z,R), (Z,S), (E,R), (E,S)]. Moreover, enantiopure non-natural alpha-amino acids are highly sought after in organic and medicinal chemistry. In this study, we report a ligand-controlled stereodivergent synthesis of non-natural alpha-quaternary amino acids ...

  摘要：Humans cooperate to build complex structures with culture-specific architectural styles. However, they are not the only animals to build complex structures nor to have culture. We show that social groups of white-browed sparrow weavers (Plocepasser mahali) build structures (nests for breeding and multiple single-occupant roosts for sleeping) that differ architecturally among groups. Morphological differences are consistent across years and are clear even among groups with territories a few met...
