OBJECTIVE To investigate the expression of LncRNA TUG1 in hypertensive patients and its relationship with the change state of illness. PATIENTS AND METHODS A prospective analysis was carried out. Eighty-two patients with hypertension admitted to our hospital from March 2016 to February 2019 were regarded as a research group, and 79 healthy people admitted to our hospital during the same period were regarded as a control group. The serum LncRNA TUG1, platelet activating factor (PAF), endothelin-1 (ET-1), serum tumor necrosis factor-α (TNF-α), high sensitive C-reactive protein (hsCRP), and the relationship between the expression of LncRNA TUG1 and the clinicopathological characteristics of patients with hypertension in the two groups were detected, and finally, the risk factors of hypertension were analyzed. RESULTS The expression levels of LncRNA TUG1, PAF, ET-1, TNF-α, and hsCRP in the serum of patients in research group were significantly higher than those in control group (p<0.05). LncRNA TUG1 has a positive correlation with the severity of an illness of hypertensive patients (r=0.881, p<0.001), and also has a positive correlation with the expression levels of PAF, ET-1, TNF-α, and hsCRP (r=0.735, p<0.001; r=0.756, p<0.001; r=0.712, p<0.05; r=0.723, p<0.05). The expression of LncRNA TUG1 in the serum of patients with hypertension was related to hypertension mode, severity of disease, hyperlipidemia, and obesity (p<0.05). Obesity (OR: 3.469, 95% CI: 2.175-4.095), drinking (OR: 3.677, 95% CI: 1.695-4.892), hyperlipidemia (OR: 3.374, 95% CI: 1.759-6.988), and the high expression of TUG1 (OR: 2.693, 95% CI: 1.679-7.472) are independent risk factors for the attack of hypertension. CONCLUSIONS LncRNA TUG1 is highly expressed in the serum of hypertensive patients and it is closely related to the progression of hypertension. Also, it may be one of the independent risk factors for hypertension and a new molecular target for hypertension treatment.
