Summary: Given the intrinsic and potential resistance of Pseudomonas aeruginosa to antibiotics, it is crucial to develop new therapeutic options for infections caused by this bacterium. Bacterial metabolic pathways are being explored as potential targets for new antibiotics. This study investigates the metabolic mechanisms of glycerol and its intermediate glycerol 3-phosphate (G3P) in P. aeruginosa PAO1. The results reveal the importance of G3P homeostasis for the growth and virulence factor production of P. aeruginosa PAO1. The enzyme GlpD, involved in G3P catabolism, is identified as a potential therapeutic target for the prevention and treatment of P. aeruginosa infections.

Summary: Recent studies demonstrate that changes in energy metabolism in activated microglia play a role in their immune responses in the ischemic brain. Noggin, an antagonist of bone morphogenetic protein, has been found to enhance myelination in the ischemic brain, and conditioned media (CM) from activated BV2 microglia treated with noggin can increase the expression of myelin basic protein (MBP) in oligodendrocytes. Metabolite analysis revealed that noggin treatment suppressed the increase in intracellular glucose and lactate levels in BV2 cells after ischemia/reperfusion (I/R), but increased extracellular levels of glucose and several amino acids. In MO3.13 cells, noggin CM reversed changes in metabolite levels induced by vehicle CM, suggesting that noggin-induced metabolic changes in microglia create a favorable environment for myelin synthesis in oligodendrocytes.

Summary: The enzyme glycerol-3-phosphate dehydrogenase 1 (GPDH1) plays essential roles in the development and metabolism of Drosophila melanogaster. Depletion of maternal and zygotic pools of GPDH1 affects larval development, lifespan, fat storage, oogenesis, and embryogenesis. Metabolomics analysis further reveals metabolic adaptations in GPDH1 mutants that differ between generations. These findings expand our understanding of GPDH1's functions in early development and provide insights into the survival mechanisms of flies lacking this key enzyme.

Summary: This study found that GPD1 acts as a tumor suppressor in breast cancer by inhibiting proliferation, migration, and invasion of cancer cells through activating lipid synthesis and the PI3K/AKT signaling pathway. Additionally, a positive correlation was observed between GPD1 level and survival rate in breast cancer patients. Therefore, GPD1 could serve as a prognostic biomarker and potential therapeutic target for breast cancer.

Summary: In this study, plasma metabolomics profiling was performed to explore the metabolic pathways involved in the tumorigenesis of medullary thyroid cancer (MTC). The results revealed perturbations in the biosynthesis of unsaturated fatty acids and amino acid metabolisms, particularly leucine, glutamine, and glutamate, which are tightly responsible for tumor cells' energy production. Furthermore, specific metabolites such as linoleic acid, linolenic acid, and leucine showed high discriminatory power in distinguishing MTC patients from healthy individuals. This research provides insights into the metabolic profile of MTC and highlights the potential of metabolomics as a diagnostic tool.

Summary: The research on sustainable alternatives for producing valuable polyunsaturated fatty acids (PUFAs) has been promoted due to the limited supply of wild deep-sea fish and the potential accumulation of toxic pollutants. In this study, an evolved strain of Phaeodactylum tricornutum microalgae was generated through adaptive evolution, resulting in enhanced biomass and PUFA production capabilities. The use of food waste hydrolysate as a carbon source further improved biomass yield and PUFA production. This study provides novel insights into sustainable microalgal-based waste valorisation for PUFA production.

Summary: Microalgae are being investigated as green cell factories for biochemistry and pollution control. This study focuses on enhancing the synthesis of selenium nanoparticles (SeNPs) in microalgae and understanding the molecular mechanisms involved. Chlorella vulgaris was fortified with quercetin to promote SeNPs biotransformation. Quercetin facilitated the formation of SeNPs within 72 hours, converting almost 97% of inorganic selenite to SeNPs. Electron microscopy confirmed the biogenic ability of the algal system. Quercetin fortification protected C. vulgaris from selenite-induced impairment and improved its growth rate, while also altering the fatty acid profile.

Summary: In this study, the genetic structure and diversity of Colletotrichum gloeosporioides, the dominant species causing citrus anthracnose, were analyzed using the Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene. A total of 19 GAPDH haplotypes were identified, with the main haplotype (haplotype 5) distributed widely among isolates from different Citrus species and locations. The genetic differentiation index (Fst) revealed significant genetic differentiation between populations from different regions and host species. The results suggest that genetic differentiation in C. gloeosporioides is mainly influenced by gene mutation, recombination, or migration within native populations rather than natural selection caused by geography or host variety.

Summary: The excessive accumulation of catechol in the environment due to its burgeoning commercial applications poses a severe ecological threat. This study investigated the potential of the microalga Crypthecodinium cohnii to degrade catechol and utilize the byproduct as a carbon source. Results showed that catechol significantly increased the growth of C. cohnii and was rapidly catabolized within 60 hours. Transcriptomic analysis identified key genes involved in catechol degradation, and real-time polymerase chain reaction (RT-PCR) analysis revealed a remarkable increase in the transcription of these genes. The study also demonstrated altered primary metabolite content and the ability of C. cohnii to tolerate catechol treatment without adverse effects.

Summary: This study conducted Life Cycle Assessments (LCA) to evaluate the environmental impact of laboratory-scale EPA production by Phaeodactylum tricornutum. The results showed that technical advancements, particularly metabolic engineering, significantly reduced the global warming potential and cumulative energy demand associated with EPA production. Electricity consumption and extraction solvents were identified as the main contributors to the environmental impact. The study suggests future directions should focus on increasing EPA productivity, adopting alternative cultivation approaches with less energy input, and implementing environmentally friendly methods for EPA recovery.

Summary: Studies have found that there are reciprocal inhibitory effects between Karenia mikimotoi and Prorocentrum shikokuense under co-cultures. RNA sequencing analysis revealed that genes involved in photosynthesis, carbon fixation, energy metabolism, nutrients absorption and assimilation were up-regulated in K. mikimotoi after co-cultured with P. shikokuense, while genes involved in DNA replication and cell cycle were down-regulated. In contrast, genes involved in energy metabolism, cell cycle, and nutrients uptake and assimilation were down-regulated in P. shikokuense under co-culture with K. mikimotoi. Additionally, the expression of PLA2G12 and nitrate reductase, which may play important roles in the allelopathy of K. mikimotoi, was significantly increased. These findings provide new insights into the interspecies competition between K. mikimotoi and P. shikokuense and offer a novel strategy for studying interspecific competition in complex systems.
