Aberrant activation of platelet-derived growth factor receptor α (PDGFRA) has been implicated in tumorigenesis and radioiodine resistance of thyroid cancer, indicating its therapeutic potential. In the present study, we confirmed the association between PDGFRA and radioiodine resistance in thyroid cancer using bioinformatics analysis and constructed a prediction model of PDGFRA inhibitors using machine learning and molecular docking approaches. We then performed a virtual screening of a traditional Chinese medicine (TCM) derived compound library and successfully identified 4',5,7-trimethoxyflavone as a potential PDGFRA inhibitor. Further characterization revealed a significant inhibitory effect of 4',5,7-trimethoxyflavone on PDGFRA-MAPK pathway activation, and that it could upregulate expression of sodium iodide symporter (NIS) as well as improve radioiodine uptake capacity of radioiodine-refractory thyroid cancer (RAIR-TC), suggesting it a potential drug lead for the development of new RAIR-TC therapy.

Background: Voghera pepper (VP) extracts were demonstrated to have anti-oxidant ability in several cell types.
Purpose: This study aimed to assess whether VP-extracts could lower oxidative stress and modulate thyroid cancer (TC) cells behavior .
Methods: Extracts were analyzed using the LC-DAD-MS system.

Introduction: The prognosis of anaplastic thyroid carcinoma (ATC) remains poor. Mutation-based targeted therapies and immune checkpoint inhibitors (ICI) have gained increasing importance in the treatment of advanced tumor stages. This study aimed to investigate whether mutation-based neoadjuvant therapy can convert an initially unresectable tumor into a resectable state, optimizing local tumor control and prolonging overall survival.

Isolated ectopic secretion of corticotropin-releasing hormone (CRH) is an exceedingly rare cause of Cushing's syndrome (CS), accounting for fewer than 1% of cases. Ectopic CS is an uncommon but potentially life-threatening condition that often necessitates urgent diagnostic evaluation and treatment. Hormonal testing may suggest a pituitary origin, complicating the diagnostic process.

Objective: This study aimed to investigate comorbidity patterns and potential pathogenic mechanisms in patients with Hashimoto's thyroiditis (HT).
Methods: Patients with HT who visited the outpatient clinic of the Thyroid Department at Dongzhimen Hospital, Beijing University of Chinese Medicine, between June 2021 and December 2024 were included. Association rule analysis and logistic regression analysis were performed using SPSS 25.

Nuclear receptors (NRs) are a superfamily of ligand-activated transcription factors that regulate gene expression in response to metabolic, hormonal, and environmental signals. These receptors play a critical role in metabolic homeostasis, inflammation, immune function, and disease pathogenesis, positioning them as key therapeutic targets. This review explores the mechanistic roles of NRs such as PPARs, FXR, LXR, and thyroid hormone receptors (THRs) in regulating lipid and glucose metabolism, energy expenditure, cardiovascular health, and neurodegeneration.
