Per- and polyfluoroalkyl substances (PFAS) exposure is associated with radioiodine therapy resistance and dedifferentiation of differentiated thyroid cancer.

Differentiated thyroid cancer (DTC) generally has a favorable prognosis, and radioactive iodine (RAI) therapy is typically used for metastatic DTC that continues to progress and poses life-threatening risks. However, resistance to RAI in metastatic DTC significantly impairs treatment effectiveness. This study aims to identify potential compounds that may influence RAI efficacy.

TGF-β signaling and microRNA cross-talk regulates abdominal aortic aneurysm progression.

Abdominal aortic aneurysms (AAA) are permanent and irreversible local dilatations of the abdominal aortic wall. Recent data indicate that the transforming growth factor-beta (TGF-β) signaling pathway exerts a protective effect on the development of AAA. Some dysregulated microRNAs (miRNA) also appear involved in the expansion of AAA and miRNA-based therapeutics have been shown to effectively inhibit this process.

Intestinal microbiota-farnesoid X receptor axis in metabolic diseases.

Studies have demonstrated that intestinal microbiota is associated with various metabolic diseases including obesity, nonalcoholic fatty liver, and insulin resistance. Farnesoid X receptor (FXR), also known as the bile acid receptor, belongs to the nuclear receptor superfamily, which is involved in the regulation of bile acid, glucose, and lipid metabolism. Researchers have found that intestinal microbiota can regulate FXR activity by affecting bile acid composition, and then regulate the balance of in vivo metabolism.

Extracellular vesicles in vascular calcification.

Vascular calcification is associated with adverse cardiovascular events that increase the risk of cardiovascular death. Unfortunately, the pathogenesis of vascular calcification is complex and incompletely understood. As important intercellular signaling molecules, the role of extracellular vesicles (EVs) in vascular calcification has attracted wide attention in recent years.
