Sestrins are an evolutionarily conserved, stress-inducible protein family that reduces oxidative stress and regulates the adenosine monophosphate-dependent protein kinase (AMPK)-mTOR signaling pathway. The aim of this study was to investigate the potential role and significance of sestrin 2 (SESN2), a member of the sestrin family, in Hashimoto\u2019s disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross-sectional study included patients with Hashimoto\u2019s disease and healthy volunteers.

Median SESN2 levels in the patient group (1.36 ng\/mL (1.10\u20132.03)) were significantly lower than in the control group (1.83 ng\/mL (1.34\u20132.64)) (P = 0.002).

These results indicate that further research is needed to better understand the effect of regulation of SESN2 in Hashimoto\u2019s disease on the course and pathological processes of the
