RREB1 promotes the development of parafollicular carcinogenesis through the Ras-Raf-1-ELK3 signaling pathway

Thyroid cancer (TC) is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) is derived from parathyroid follicle cells (C cells) secrete calcitonin, accounting for approximately 5-10% of all thyroid cancers. The malignancy is between differentiated and undifferentiated thyroid cancer and undifferentiated thyroid cancer and has a relatively poor prognosis. In MTC tumor cells, RREB1 regulates the differentiation of parathyroid cells via RAS-Raf-1-ELK3 signaling and induce calcitonin secretion. Therefore, it is easy to induce parathyroid parafollicular cells canceration and medullary thyroid carcinoma. Here, we investigated the correlation between RREB1, RAS-Raf-1-ELK3 signaling pathway and medullary thyroid carcinoma with various phases. Our results suggest that RREB1 promotes parafollicular carcinoma through the Ras-Raf1-elk3 signaling pathway, providing a rationale to further investigate the role of RREB1 in parafollicular carcinoma. It provides theoretical guidance for the clinical treatment of medullary thyroid cancer.
