Embodiment 1

[0036] 1. Materials and methods

[0037] 1.1 Cell culture and treatment

[0038] Human retinal microvascular endothelial cells (HRMECs) were obtained from the American Type Culture Collection (USA) and grown in the presence of 10% fetal bovine serum (FBS; Invitrogen, USA), 1% penicillin / streptomycin (Invitrogen), endothelial cells Factor (EGM; SingleQuots, Clonetics, San Diego, USA) in endothelial basal medium (LonzaGroup, Switzerland); cells were incubated in 5% CO 2 Maintain the culture at 37 °C under humidified conditions. For high glucose treatment, HRMECs treated with 30 mM dextrose ((Sigma, USA) for 48 h, treated with normal glucose (5.5 mM) or mannitol (24.5 mM) plus glucose (5.5 mM) were used as controls. For cells For transfection, OE-NC (negative control plasmid), OE-SNHG7, miR-NC, miR-34a-5p mimic, inhibitor NC, miR-34a were transfected with Lipofectamine 3000 (Invitrogen, Carlsbad, CA, USA) -5p inhibitor, sh-NC, sh-XBP1 delivered in the cell.24 hours after the t...

Abstract

The invention belongs to the field of biology, and particularly relates to application of lncRNA SNHG7 in preparation of a medicine for treating retinopathy. The lncRNA SNHG7 is derived from an exosome of a bone marrow mesenchymal stem cell. Through the interaction with the miR-34a-5p / XBP1 signal pathway, the exosome SNHG7 derived from the mesenchymal stem cells can inhibit the EndMT and tube formation of HRMECs induced by high glucose exposure, which may provide a feasible therapeutic target for the treatment of diabetic retinopathy.

Description

technical field [0001] The invention belongs to the field of biology, and in particular relates to an application of lncRNA SNHG7 in the preparation of drugs for treating retinopathy. Background technique [0002] Diabetic retinopathy (DR) is one of the most serious neurovascular complications of type 2 diabetes mellitus (T2DM) and the leading cause of vision-impairing blindness. Retinal endothelial cells serve as the first barrier to monitor changes in blood glucose, and evidence has shown that high glucose (HG) initiates retinal endothelial cell proliferation and migration, which are key steps in the development of DR. Although a new generation of drugs and vitreoretinal microsurgery have been applied clinically to treat DR, the prevalence of DR has risen sharply in the past decades. Therefore, further elucidation of the etiology of DR is crucial to improving currently available treatments. [0003] Endothelial to mesenchymal transition (EndMT), characterized by decrea...
