Pre-existing thyroiditis ameliorates papillary thyroid cancer: insights from a new mouse model.

Endocrinology 2021 Jul 31. Epub 2021 Jul 31.

Division of Immunology, Department of Pathology, The Johns Hopkins School of Medicine, Ross Research Building-Room 656, 720 Rutland Avenue, Baltimore, MD, 21205, USA.

Papillary Thyroid Cancer (PTC) often co-occurs with Hashimoto's thyroiditis, an association that has long been reported in clinical studies yet remains controversial. Some studies, in fact, have suggested a protective effect of thyroiditis while others have not. We generated a mouse model where PTC and thyroiditis develop in a predictable manner, combining the oncogenic drive of the BRAF v600E mutation (inducible by tamoxifen) to the thyroiditis susceptibility of the NOD.

Hashimoto thyroiditis is characterized by anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies that gradually lead to thyroid cell destruction. As hypothyroidism has been associated with insulin resistance (IR), we aimed to investigate whether IR is associated with thyroid antibody presence and whether the degree of IR correlates with their concentration in euthyroid individuals. A total of 164 non-diabetic, euthyroid individuals, average age 34 years, were included in the study, divided into two groups according to Hashimoto thyroiditis and underwent 5-hour oral glucose tolerance test.
