The Haematococcus pluvialis extract enriched by bioaccumulation process with Mg(II) ions improves insulin resistance in equine adipose-derived stromal cells (EqASCs).

The research article examines the beneficial effects of a magnesium-enriched extract from Haematococcus pluvialis algae on insulin resistance in equine adipose-derived stromal cells.

Objective of the study

• The study researched the impact of a special extract derived from Haematococcus pluvialis algae, enriched with magnesium ions (Hp_Mg(II)), on insulin resistance in horse fat-derived mesenchymal stromal stem cells (equine adipose derived mesenchymal stromal stem cells).
• It was observed that insulin resistance was induced in these cells with the introduction of palmitic acid, forming a model of insulin-resistant cells called IR-EqASCs.
• The aim was to understand whether the algae extract treatment could improve insulin sensitivity — a crucial aspect of managing diseases like equine metabolic syndrome.

Research methodology

• The research team used several molecular biology methods and microscopic observations, including gene expression analysis, proliferative and metabolic cells activity analysis, immunofluorescence staining and Scanning Electron Microscopy (SEM).
• They investigated aspects such as cell viability, proliferation, influence on oxidative stress markers, apoptotic factors, and associated gene expressions.
• The algae sample physiochemical properties were also studied, including its mineral composition, phenolic content, carotenoid content and its capacity to scavenge free radicals (scavenging activity).

Key findings

• Results showed that Hp_Mg(II) markedly improved the proliferative and metabolic activity of the insulin-resistant stem cells.
• It also reduced the time it took for the cells to double in number and improved their clonogenic potential, which is the ability to form new colonies.
• The extract also decreased the expression of genes related to apoptosis, which correlates with less programmed cell death. Furthermore, the extract exhibited antioxidant effects, which can reduce oxidative stress.

Implications of the research

• This study highlights the potential of the magnesium-enriched Haematococcus pluvialis algae extract in managing insulin resistance, especially in the context of equine health.
• This could potentially become an alternative or complementary measure to the current fare of treatments, which primarily focus on caloric restrictions and mineral supplementation.
• More research is required to confirm these findings and explore potential applications in other species and conditions related to insulin resistance.
