Abstract:
Objective:Our previous micro-array study revealed that long non-coding RNA (lncRNA), such as ENST00000538790 and NR_125790, were differently expressed in parathyroid carcinoma compared with those in parathyroid adenoma. Diagnostic value of lncRNAs (ENST00000538790 and NR_125790) and scoring models derived from these lncRNAs in parathyroid carcinoma were investigated in this study.Methods:Fifty-seven fresh tissue samples from patients with hyperparathyroidism were collected. Eleven patients were diagnosed with parathyroid carcinoma, while 46 patients were found with parathyroid adenoma. The expression levels of five lncRNAs (ENST00000511928, ENST00000538790, ENST00000618339, NR_125790, and ENST00000485384) were detected with realtime quantitative PCR (RT-qPCR). LncRNA scores were calculated using these lncRNAs, and their value in parathyroid carcinoma diagnosis were also assessed.Results:It was found that expression levels of ENST00000511928 and ENST00000538790 were up-regulated in parathyroid carcinoma compared with parathyroid adenoma ( P<0.05), while the levels of ENST00000618339, NR_125790, and ENST00000485384 were decreased in parathyroid carcinoma ( P<0.05). Among these lncRNAs, ENST00000538790 and NR_125790 were independent risk factors for parathyroid carcinoma ( P<0.05). Hence, "log score" and "logistic score" were calculated with ENST00000538790 and NR_125790 levels. The areas under the receiver operating characteristic curve for "log score" and "logistic score" were up to 0.935 and 0.943 respectively in parathyroid carcinoma ( P<0.05), and were found to be greater than those from single lncRNA or classic clinical indices, such as serum calcium ( P<0.05). Conclusion:LncRNA scores with lncRNA ENST00000538790 and NR_125790 may play potential role in diagnosis of parathyroid carcinoma.
