Background: Transforming growth factor beta receptor III (TGFBR3) has been shown to play a tumor suppressive role in a variety of cancers. However, its role in papillary thyroid cancer (PTC) remains unknown.

Method: TGFBR3 expression levels in PTC were analyzed utilizing TCGA and GEO database. Edu, wounding healing and Transwell assays were used to evaluate cell proliferation, migration and invasion. Transcriptome sequencing, qRT-PCR and Western blotting were used to detect the underlying mechanism of TGFBR3 in PTC progression.

Result: This study demonstrated that TGFBR3 expression was significantly down-regulated in PTC compared to normal thyroid tissues. Low expression of TGFBR3 was associated with poor prognosis of patients with PTC. Furthermore, TGFBR3 expression positively correlated with thyroid differentiation score. In investigating the biological impact of TGFBR3 over-expression in PTC cell lines, we found that the proliferation, migration and invasion of PTC cells were significantly inhibited in response to TGFBR3 overexpression. Moreover, we also demonstrated that overexpression of TGFBR3 inhibited PI3K/AKT pathway and epithelial mesenchymal transformation processes. Lastly, TGFBR3 expression was found to be involved in tumor immune infiltration, highlighting its potential influence on immune dynamics within the tumor microenvironment in PTC.

Conclusion: TGFBR3 plays a tumor suppressive role in PTC progression by inhibiting PI3K/AKT pathway and EMT.
