Abstract:
Background: Aberrant angiogenesis plays a fateful role in the development of diabetes
and diabetic complications. Lipids, as a diverse group of biomacromolecules, are able to relieve diabetes
through the modulation of angiogenesis.
Objectives: Owing to the present remarkable anti-diabetic effects with no or few side effects of
lipids, the aim of this study was to assess the state-of-the-art research on anti-diabetic effects of
lipids via the modulation of angiogenesis.
Methods: To study the effects of lipids in diabetes via modulation of angiogenesis, we have
searched the electronic databases including Scopus, PubMed, and Cochrane.
Results: The promising anti-diabetic effects of lipids were reported in several studies. Eicosapentaenoic
acid (EPA) and docosahexaenoic acid (DHA) from fish oil (FO) were reported to significantly
induce neovasculogenesis in high glucose (HG)-mediated endothelial progenitor cells (EPCs)
with neovasculogenesis dysfunction in type 2 diabetic mice. Linoleic acid, mono-epoxy-tocotrienol-
α (MeT3α), and ginsenoside Rg1 facilitate wound closure and vessel formation. N-Palmitoylethanolamine
(PEA), α-linolenic acid (ALA), omega-3 (ω3) lipids from flaxseed (FS) oil, ω-3
polyunsaturated fatty acids (PUFA), lipoic acid, taurine, and zeaxanthin (Zx) are effective in diabetic
retinopathy via suppression of angiogenesis. Lysophosphatidic acid, alkyl-glycerophosphate,
crocin, arjunolic acid, α-lipoic acid, and FS oil are involved in the management of diabetes and its
cardiac complications. Furthermore, in two clinical trials, R-(+)-lipoic acid (RLA) in combination
with hyperbaric oxygenation therapy (HBOT) for treatment of chronic wound healing in DM patients,
as well as supplementation with DHA plus antioxidants along with intravitreal ranibizumab
were investigated for its effects on diabetic macular edema.
Conclusion: Proof-of-concept studies presented here seem to well shed light on the anti-diabetic effects
of lipids via modulation of angiogenesis.
