Background: Diabetic nephropathy (DN) is a diabetic complication. LncRNAs are reported to participate in the pathophysiology of DN. Here, the function and mechanism of lncRNA small nucleolar RNA host gene 14 (SNHG14) in DN were explored.
Methods: Streptozotocin (STZ)-induced DN mouse models and high glucose (HG)-treated human mesangial cells (MCs) were used to detect SNHG14 expression. SNHG14 silencing plasmids were applied to examine the function of SNHG14 on proliferation and fibrosis in HG-treated MCs. Potential targets of SNHG14 were predicted using bioinformatics tools and verified by luciferase reporter, RNA pulldown, and northern blotting assays. The functional role of SNHG14 in DN in vivo was detected by injection with adenoviral vector carrying sh-SNHG14 into DN mice. Serum creatinine, blood urea nitrogen, blood glucose, 24-h proteinuria, relative kidney weight, and renal pathological changes were examined in DN mice.
Results: SNHG14 expression was elevated in the kidneys of DN mice and HG-treated MCs. SNHG14 silencing inhibited proliferation and fibrosis of HG-stimulated MCs. SNHG14 bound to miR-30e-5p to upregulate SOX4 expression. In rescue assays, SOX4 elevation diminished the effects of SNHG14 silencing in HG-treated MCs, and SOX4 silencing reversed the effects of SNHG14 overexpression. In in vivo studies, SNHG14 downregulation significantly ameliorated renal injuries and renal interstitial fibrosis in DN mice.
Conclusions: SNHG14 silencing attenuates kidney injury in DN mice and reduces proliferation and fibrotic phenotype of HG-stimulated MCs via the miR-30e-5p/SOX4 axis.

Abdominal aortic aneurysm (AAA) is a global health concern associated with high mortality. It has been reported that long noncoding RNAs (lncRNAs) are involved in the development of AAA. In this study, our objective was to investigate the roles of lncRNA small nucleolar RNA host gene 14 (SNHG14) and the associated mechanisms in the development of AAA.

Prader-Willi Syndrome (PWS) is caused by the loss of expression of paternally expressed genes in the human 15q11.2-q13 imprinting domain. A set of imprinted genes that are active on the paternal but silenced on the maternal chromosome are intricately regulated by a bipartite imprinting center (PWS-IC) located in the PWS imprinting domain.

Background: Cisplatin (DDP) is one of the commonly used chemotherapeutic drugs for nasopharyngeal carcinoma (NPC) patients, and the resistance of tumor cells to cisplatin is main obstacle for NPC treatment. This study explored effect and possible mechanism of lncRNA small nucleolar RNA host gene 14 (SNHG14) on drug resistance of NPC cells to cisplatin.
Methods: Levels of SNHG14 and Notch2 in NPC tissues and cells were confirmed using RT-qPCR.

Background: Genetic alterations have important roles in cancer development and progression. (spindle and kinetochore associated complex subunit 2) is a mitotic component that plays a critical role in maintaining the silence of the metaphase plate and spindle checkpoint. However, the exact role of in hepatocellular carcinoma (HCC) remains unclear.

Purpose: This study explored the clinical value of long non-coding RNA small nucleolar RNA host gene 14 (SNHG14) in diabetic kidney disease (DKD) and the mechanism of renal tubular injury.
Methods: Patients with DKD, type 2 diabetes mellitus (T2DM) and healthy individuals (HVs) were included, as well as the human proximal tubular epithelial cell line (HK-2) induced by high glucose was also included. The mRNA levels of SNHG14 in the serum and cells were detected using RT-qPCR.
