A novel anti-HER2/EGFR bispecific antibody-drug conjugate demonstrates promising antitumor efficacy and overcomes resistance to HER2- or EGFR-targeted ADCs.

HER2 and EGFR are frequently co-expressed in various tumors. While antibody-drug conjugates (ADCs) targeting HER2, such as T-DM1 and T-Dxd, have shown remarkable antitumor effects in clinical responses, their effectiveness is constrained by drug resistance. EGFR amplification or high expression is one of the factors that lead to resistance against HER2-targeted ADCs.

Ginger protects against vein graft remodeling by precisely modulating ferroptotic stress in vascular smooth muscle cell dedifferentiation.

Vein graft (VG) failure (VGF) is associated with VG intimal hyperplasia, which is characterized by abnormal accumulation of vascular smooth muscle cells (VSMCs). Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition, also known as dedifferentiation. There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation, exerting vasoprotective functions; however, the precise mechanisms have not been fully characterized.
