Cancer Molecular Pathology of School of Medicine and Dentistry, Menzies Health Institute Queensland, Griffith University, Gold Coast, QLD, Australia.

Histologic assessments of papillary thyroid carcinoma are crucial for management of patients with the cancer as well as research on the cancer as papillary thyroid carcinoma has different histologic subtypes and many parameters which are essential in predicting the biological aggressiveness of the cancer. The histologic assessments should be guided by universally adopted protocols including World Health Organization (WHO) classification of endocrine tumors, International Collaboration on Cancer Reporting (ICCR) dataset, American Thyroid Association initial risk stratification for differentiated thyroid carcinomas and TNM stage groupings. The essential steps in histologic assessment involve the identification of characteristic features of papillary thyroid carcinoma, correct histologic subtyping, noting the number of carcinomas, measuring the size of the carcinoma, documenting the different aggressive histological parameters (mitotic activity, presence of tumor encapsulation/circumscription, lymphatic vessel invasion, blood vessel invasion, necrosis, extrathyroidal extension), resection margin status, associated pathology, presence of parathyroid gland, lymph node and distant metastases as well as synthesis of pathological stage based on the various clinical, macroscopic, and histological features.

NOD1 activation promotes cell apoptosis in papillary thyroid cancer.

Pathol Res Pract 2022 May 11;233:153880. Epub 2022 Apr 11.

Department of Stomatology, Affiliated Hospital of Jiangnan University, Wuxi 214062, Jiangsu Province, China. Electronic address:

Background: NOD1 can promote or inhibit different types of cancers, suggesting that NOD1 functions in the progression of cancers dependent on the tumour environment. However, the expression and mechanisms of NOD1 during papillary thyroid carcinoma (PTC) progression remain unclear.

Methods: To investigate the role of NOD1 in PTC development and apoptosis, we detected NOD1 expression in three cell lines and surgical specimens from patients with PTC using immunohistochemistry, quantitative real-time PCR (Q-PCR) and Western blotting; we studied the biological functions of NOD1 by loss-of-function analysis of TPC-1 and BCPAP cells and the effect of NOD1 on the progression of PTC in terms of cell proliferation and apoptosis induced by tumour necrosis factor alpha (TNF-α), Fas ligand (Fas L), tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) or Ala-γGlu-diaminopimelic acid (TriDAP) in the presence of cycloheximide (CHX) and determined its underlying molecular mechanism using PTC cell lines in vitro and mouse xenograft models in vivo.
