Harnessing ROS Amplification and GSH Depletion Using a Carrier-Free Nanodrug to Enhance Ferroptosis-Based Cancer Therapy.
Small
December 2024
Department of Polymer Science and Engineering, University of Science and Technology of China, Hefei, 230026, P. R. China.
Ferroptosis, a non-apoptotic form of cell death characterized by the production of reactive oxygen species (ROS) and massive accumulation of lipid peroxidation (LPO), shows significant promise in cancer therapy. However, the overexpression of glutathione (GSH) at the tumor site and insufficient ROS often result in unsatisfactory therapeutic efficacy. A multistage, GSH-consuming, and ROS-providing carrier-free nanodrug capable of efficiently loading copper ions (Cu), sorafenib (SRF), and chlorogenic acid (CGA) (Cu-CGA-SRF, CCS-NDs) is developed to mediate enhanced ferroptosis therapy.

Department of Pathology and Pathophysiology, School of Medicine, Jianghan University, 8 Sanjiaohu Road, Wuhan, 430056, China.
Dysregulated expression of microtubule-associated protein tau (MAPT) has been reported in a variety of human cancers. However, whether and how Tau influences hepatocellular carcinogenesis remains elusive. This study was aimed to investigate the role and the underlying mechanism of Tau in the proliferation, invasion, migration and sorafenib sensitivity of hepatocellular carcinoma (HCC) cells.

Drug Dev Res
February 2025
Pharmaceutical Medicinal Chemistry and Drug Design Department, Faculty of Pharmacy (Boys), Al-Azhar University, Nasr City, Cairo, Egypt.
New phthalazine-derived inhibitors for VEGFR-2 were synthesized for anticancer evaluations. Also, docking studies were performed to explore the suggested binding orientations of the novel derivatives inside the binding site of VEGFR-2. The achieved biological data were extremely interrelated to that of docking study.

Liver cancer, encompassing hepatocellular carcinoma (HCC) and hepatoblastoma, the latter of which primarily occurs in early childhood, is the most common malignant tumor arising from liver and is responsible for a significant number of cancer-related deaths worldwide. Targeted drugs have been used for anti-liver cancer treatment in the advanced stage, while their efficacy is greatly compromised by development of drug resistance. Drug resistance is a complicated process regulated by intrinsic and extrinsic signals and has been associated with poorer prognosis in cancer patients.

We aimed to determine the effects of piperine on cell viability, cellular stresses, and apoptosis first, then the relationship of piperine's effects with the c-Jun N-terminal kinase (JNK) signaling pathway, and also the interaction of piperine with sorafenib in hepatocellular carcinoma. Hepatocellular carcinoma (HepG2 and Hep3B) and non-cancerous hepatocyte (AML12) cell lines were used. The cell viability was determined by using MTT assay.
