Summary: The deposition of storage fat in the form of triacylglycerol (TAG) is a conserved strategy to cope with energy availability and metabolic stress. The fruit fly Drosophila melanogaster has been established as a model system to study TAG metabolism and the etiology of lipid-associated metabolic diseases, showing potential in understanding the genetic and dietary basis of TAG storage and related disorders.

Summary: This study found that deletion of one copy of the atpD gene in M. smegmatis leads to an energy-compromised state, resulting in a major routing shift in electron flux through less efficient respiratory chain complexes and an increased reduced state. This alteration further modulates the biosynthesis of cell wall associated lipids and triacylglycerol (TAG), with an accumulation of TAG-containing lipid bodies. Moreover, the mutant shows overexpression of TAG-degrading lipase genes, indicating a shift towards utilizing TAG as an energy source.

Summary: Yarrowia lipolytica yeast is a model species capable of accumulating intracellular lipids. The synthesis of lipids can follow either a de novo pathway or an ex novo pathway. The ex novo pathway is influenced by the limitation of nitrogen source in the medium. It was also found that lipid synthesis in lipid-rich medium mainly occurs via the ex novo pathway.

Summary: This study investigates the potential of using the oleaginous fungus Mortierella alpina to bio-flocculate starchless mutants of Chlamydomonas reinhardtii. By adjusting the nitrogen regime, the lipid concentration of triacylglycerides (TAG) reaches 85%. Scanning electron microscopy reveals that cell-wall attachment and extra polymeric substances (EPS) are responsible for algal flocculation. The optimal algal-fungal biomass ratio of 1:1 results in 80-85% flocculation efficiency in 24 hours. Utilizing nutrient-deprived sta6/sta7 mutants and various strains of M. alpina achieves fatty acid profiles similar to C. reinhardtii, including arachidonic acid (ARA).

Summary: Atherosclerotic cardiovascular disease (ASCVD) is a major global cause of death. Genetic and epidemiological studies have shown a strong association between triacylglycerol-rich lipoproteins (TAGRL) and atherogenesis, even in patients receiving statin treatment. Variants in key genes involved in TAGRL metabolism have been found to be strongly linked to increased ASCVD risk. MiRNA-based therapeutic approaches, which target dysregulated miRNAs involved in TAGRL metabolism, show promise but have not yet been tested in human trials. This review provides an overview of current interventions for hypertriglyceridemia and the development of miRNA and siRNA-based drugs as potential therapeutics for ASCVD.

Summary: The emergence of sn-1,2-diacylglycerol-3-acyltransferases (DGATs) is considered a significant development in the organic world and plant evolution, but their diverse nature and functions pose many questions. However, in-depth research on DGATs holds great potential for biotechnology and genetic engineering of functional lipids in industries such as food, pharmaceuticals, and agriculture.
