Although 30 years have passed since the description of sugar-induced cell death (SICD), the specific molecular mechanism that triggers this process remains unclear. This paper attempts to shed light on the relationship between SICD and glucose catabolism. In yeast cells, glucose is involved not only in energy-producing processes but also in the synthesis of reserve hydrocarbons.

Lacto-N-neotetraose (LNnT) is a primary solid component of human milk oligosaccharides (HMOs) with various promising health effects for infants. LNnT production by GRAS (generally recognized as safe) microorganisms has attracted considerable attention. However, few studies have emphasized Pichia Pastoris as a cell factory for LNnT's production.

Positive-strand RNA viruses build viral replication organelles (VROs) with the help of co-opted host factors. The biogenesis of the membranous VROs requires major metabolic changes in infected cells. Previous studies showed that tomato bushy stunt virus (TBSV) hijacks several glycolytic enzymes to produce ATP locally within VROs.

Background: Non-conventional yeasts hold significant potential as biorefinery cell factories for microbial bioproduction. Currently, gene editing systems used for these yeasts rely on antibiotic and auxotrophic selection mechanisms. However, the drawbacks of antibiotics, including high costs, environmental concerns, and the dissemination of resistance genes, make them unsuitable for large-scale industrial fermentation.

Studies on antiaging remedies in insect models sometimes show discrepancies in results. These discrepancies could be explained by different responses of short- and long-lived strains on the antiaging remedies. The purpose of the study was to test whether life-prolonging effects of alpha-ketoglutarate (AKG), observed in nematodes and fruit flies, would be reproduced in long-lived Drosophila melanogaster flies.
