ABSTRACT
PURPOSE:
Vascular calcification is a frequently occurring complication of end-stage renal disease (ESRD). This study focused on the significance of long non-coding RNA Fas cell surface death receptor-antisense 1(lncRNA FAS-AS1) in ESRD-related vascular calcification aiming to explore a potential biomarker for the detection.METHODS:
The study enrolled 65 healthy individuals, 79 ESRD patients (48 patients with vascular calcification), and 93 early-stage (I-IV) chronic kidney disease (CKD) patients. The expression of FAS-AS1 in serum was evaluated by real-time quantitative polymerase chain reaction (PCR). The diagnostic potential of FAS-AS1 was assessed in discriminating ESRD patients, vascular calcification, and the severity of vascular calcification. In vitro, the vascular smooth muscle cells (VSMCs) were treated with a hyperphosphatemia medium to evaluate the effect of FAS-AS1 on VSMCs calcification.RESULTS:
Elevated serum FAS-AS1 was observed in ESRD patients, which could discriminate from healthy individuals and early-stage CKD patients. FAS-AS1 was associated with the development of ESRD and the occurrence of vascular calcification. FAS-AS1 was also upregulated in vascular calcification patients, especially the patients with severe calcification, which showed diagnostic significance in evaluating vascular calcification degrees. Calcified VSMCs showed significantly increased levels of Ca2+, reactive oxygen species (ROS), tumor necrosis factor-α (TNF-α), and interleukin 6 (IL-6), which was attenuated by silencing FAS-AS1.CONCLUSIONS:
FAS-AS1 discriminated ERSD patients and was associated with the occurrence of vascular calcification. The knockdown of FAS-AS1 suppressed hyperphosphatemia-induced vascular calcification via alleviating oxidative stress and inflammation.Key words
