Identifying a novel RARγ ligand and exploring its biological function [PDF]
, 2016 视黄酸受体γ(RetinoicAcidReceptorgamma，RARγ)，作为核受体超家族重 要成员之一，在生物体生长、发育、代谢、免疫、分化、增殖、炎症、凋亡等过 程中均发挥着重要作用。RARγ一般与核受体RXRα形成异源二聚体形式，在细 胞核发挥调控基因转录的活性。但是近年来的研究发现，RARγ以及其他一些核 受体会出核与胞质中的蛋白直接相互作用进而快速参与到胞外的信号调控，发挥 核受体的“非基因型作用”。因此，RARγ一直以来都是药物干预和治疗过程中 重要且极具吸引力的靶点 ...

Rare Metals, EarlyView.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Rare Metals, EarlyView.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...
