Clinical implication of xenotropic and polytropic retrovirus receptor 1 in papillary thyroid carcinoma / 浙江大学学报·医学版

ABSTRACT

To investigate the expression of xenotropic and polytropic retrovirus receptor 1 （） in papillary thyroid cancer （PTC） and its clinical implication. The HPA and UALCAN databases were used to explore the expression of XPR1 in PTC and normal tissues. The cBioPortal database was used to obtain the clinical data of PTC patients and gene expression profile. The correlation of expression with gender，age，sub-types，T stage，N stage，M stage and clinical stage of patients were analyzed. Cox regression was conducted to analysis the factors affecting the prognosis of PTC patients. The mutation of was assessed through cBioPortal database. GO and KEGG analyses were used to explore the related biological pathway of involved in PTC. HPA database analysis showed that XPR1 was highly expressed in PTC tissue compared with normal tissues. UALCAN analysis displayed that expression was significantly higher in PTC tissue compared with normal tissues （0.05）. Cox regression analysis showed that was an independent prognostic factor of PTC patients （=2.894，<0.05）. The cBioPortal database indicated that the mutation appeared in 6% PTC patients; the mutation type mainly was missense and the mutation point was located at the E615K. Enrichment analysis indicated that might affect the PTC progression through involvement in metabolic pathway. is highly expressed in PTC tissues，which is associated with the prognosis of patients. Metabolic pathway associated with might play an important role in PTC progression，indicating that might be a novel biomarker for diagnosis and treatment of PTC.
