TFEB promotes Ginkgetin-induced ferroptosis via TRIM25 mediated GPX4 lysosomal degradation in EGFR wide-type lung adenocarcinoma.

: TFEB activation is associated with prolonged survival in LUAD patients, suggesting potential benefits of TFEB agonists in LUAD treatment. In this study, we identify ginkgetin (GK), derived from , as a natural TFEB agonist, which has demonstrated promising anticancer effects in our previous research. TFEB activation has been shown to promote GPX4 degradation, inducing ferroptosis; however, the specific E3 ligases, deubiquitinating enzymes (DUBs), and types of polyubiquitination chains involved remain unclear.

β-Elemene induced ferroptosis via TFEB-mediated GPX4 degradation in EGFR wide-type non-small cell lung cancer.

Introduction: β-Elemene (β-ELE), derived from Curcuma wenyujin, has anticancer effect on non-small cell lung cancer (NSCLC). However, the potential target and detail mechanism were still not clear. TFEB is the master regulator of lysosome biogenesis.

Roles of Fascin in Dendritic Cells.

Dendritic cells (DCs) are professional antigen-presenting cells that play a crucial role in activating naive T cells through presenting antigen information, thereby influencing immunity and anti-cancer responses. Fascin, a 55-kDa actin-bundling protein, is highly expressed in mature DCs and serves as a marker protein for their identification. However, the precise role of fascin in intratumoral DCs remains poorly understood.

CuH-Catalyzed Asymmetric Intramolecular Reductive Coupling of Allenes to Enones.

The CuH-catalyzed asymmetric intramolecular reductive coupling of allenes to enones is successfully realized, providing cis-hydrobenzofurans with promising yields and excellent enantioselectivities. Such brilliant enantioselectivities are partially contributed by CuH-catalyzed favorable kinetic resolution of the cyclization products. This protocol tolerates a broad range of functional groups, allowing for further construction of tricyclic and bridged-ring structures.

Efficient access to cis-decalinol frameworks: copper(i)-catalyzed borylative cyclization of allene cyclohexanediones.

Cu-catalyzed borylative cyclization of allene cyclohexanediones has been described through a tandem β-borylation and intramolecular allylic addition process, affording borylated cis-decalinols with excellent yields and diastereoselectivities. A good enantioselectivity is also achieved in the asymmetric version. The hemiboronate group in the cyclization products could be subjected to several useful transformations.
