General description
一种细胞可渗透的β-内酯酰基蛋白硫酯酶1（APT1）抑制剂（在酶促测定中IC50 = 0.67 µM），在体外和体内均能特异性阻断MDCK细胞中的Ras去棕榈酰化而不影响Ras酰化。它诱导NRas显著重新分布到内膜（1 µM），而没有明显的细胞毒性，并且显示出在同一细胞系中引起棕榈酰化Ras蛋白精确稳态定位的丧失。在50 µM时，该抑制剂在致癌的HRasG12V转化的成纤维细胞中显示出部分表型逆转。此外，它证明了APT1对磷脂酶A1、A2、Cβ和D的选择性。其′抑制作用与siRNA下调APT1的抑制作用一致。也可以作为50 mM的DMSO溶液（目录号508738）提供。

p62 is a well-characterized autophagy receptor that recognizes and sequesters specific cargoes into autophagosomes for degradation. p62 promotes the assembly and removal of ubiquitinated proteins by forming p62-liquid droplets. However, it remains unclear how autophagosomes efficiently sequester p62 droplets. Herein

Lung cancer is one of the most common cancers worldwide, causing nearly one million deaths each year. Herein, we present the effect of 2-methoxyestradiol (2-ME), the endogenous metabolite of 17β-estradiol (E2), on non-small cell lung cancer (NSCLC) cells. We observed

Abnormal activation of FAK is associated with tumor development and metastasis. Through interactions with other intracellular signalling molecules, FAK influences cytoskeletal remodelling, modulation of adhesion signalling, and activation of transcription factors, promoting migration and invasion of tumor cells. However, the
