The research aimed at whether and how lncRNA SPAG5-AS1 (SPAG5-AS1) is involved in retinal vascular dysfunction under diabetic conditions. After determination of SPAG5-AS1, miR-1224-5p, and IRS-1 expression in high glucose (HG)-treated human retinal microvascular endothelial cells (hRMECs), their respective influences on retinal vascular dysfunction was explored by cell counting kit-8, Transwell, wound-healing assay, and tube formation assay. SPAG5-AS1/miR-1224-5p/IRS-1 interaction was identified through bioinformatics analysis and luciferase reporter gene assays. As tested, SPAG5-AS1 and IRS-1 levels were induced, while miR-1224-5p was enhanced in HG-treated hRMECs. Up-regulating SPAG5-AS1 or downregulating miR-1224-5p could inhibit hRMECs proliferation, migration, and tube formation, and vice versa. SPAG5-AS1 can promote IRS-1 expression by miR-1224-5p, and depletion of IRS-1 was functional for the reversal of up-regulated SPAG5-AS1-modified influences on HG-treated hRMECs. Additionally, in diabetic rats, SPAG5-AS1 can alleviate retinal vascular dysfunction. All in all, SPAG5-AS1 attenuates diabetic retinal vascular dysfunction through miR-1224-5p/IRS-1 axis, providing a potential therapeutic strategy for DR. We examined the association between polypharmacy-an established risk factor for nonadherence in the elderly-and medication fill nonadherence in a large national sample of adolescent and young adult cancer survivors (AYAs) in the USA. We pooled data (2008-2017) from the Medical Expenditure Panel Survey. We defined polypharmacy as ≥ 3 unique medications prescribed, based on self-report and pharmacy data, and medication fill nonadherence a
