- Abstract
Differentiated thyroid cancer (DTC) is the most prevalent endocrine malignancy worldwide and requires effective prognostic markers and therapeutic targets to optimize patient outcomes. This study investigated the potential of human serum albumin (HSA) cysteine-34 (Cys34) redox state as a prognostic indicator and therapeutic avenue for DTC. A retrospective cohort study of 99 patients with DTC undergoing radioactive iodine therapy found that higher concentrations of HSA with the reduced form of Cys34 (i.e., human mercaptalbumin [HMA]) were associated with improved progression-free survival in metastatic DTC. In vitro experiments using a DTC cell line revealed that HMA induced cytotoxic effects by triggering ferroptosis, characterized by lipid peroxidation, intracellular ROS accumulation, and decreased cell viability. Ferroptosis inhibitors rescued cell viability, confirming their role in cytotoxicity. These results implicate the HSA-Cys34 redox state is a promising avenue for precision medicine in DTC, shedding light on the prognostic relevance and therapeutic potential of HMA-induced ferroptosis. They emphasize the opportunity for personalized treatment strategies to advance the management of patients with DTC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.
