This study revealed that the expression levels of serum ABHD11-AS1 in PTC patients were significantly higher than in healthy controls, and high levels were closely associated with poor prognosis. Cell experiments demonstrated that knocking down ABHD11-AS1 inhibited PTC cell proliferation and induced apoptosis, while overexpression had positive effects on survival indices.
This paper was aimed at exploring the correlation of long non-coding RNA (lncRNA)-ABHD11 Antisense RNA1 (ABHD11-AS1) with the poor prognosis of patients with papillary thyroid carcinoma (PTC) and at investigating its effects on the survival of PTC cells. Serum was respectively collected from 64 PTC patients who were admitted to our hospital (PTC group) and from 50 healthy controls who underwent physical examinations (HC group) both from April 2011 to April 2015. The expression levels of ABHD11-AS1 in the serum were detected, and the values of it for diagnosis and prognosis (5-year follow-ups) were analyzed. The knockdown and overexpression models of ABHD11-AS1 in were constructed to explore the effects of the models on their proliferation, cycles and apoptosis. According to the data, the expression levels of serum ABHD11-AS1 in the PTC patients were remarkably higher than those in the healthy controls, and the area under the curve (AUC) for distinguishing the patients from the controls was 0.920. In the analysis of prognosis, the levels in patients with a poor prognosis were remarkably higher than those in patients with a good prognosis. According to the curves of overall survival rates (OSRs), the high levels of ABHD11-AS1 were remarkably correlated with the poor prognosis (a lower 5-year OSR). COX analysis showed that TNM staging, lymph node metastasis and ABHD11-AS1 were the independent prognostic factors of PTC patients. In the cell experiments, knocking down ABHD11-AS1 remarkably inhibited PTC cells from proliferation, arrested them in G0/G1 phase, and induced their apoptosis, negatively affecting their survival indices. Overexpressing this RNA had positive effects on the survival indices. Taken together, high levels of serum ABHD11-AS1 are related to the poor prognosis of PTC patients, and knocking down its expression can inhibit the survival of PTC cells.
