Summary: Glutamic acid decarboxylase (GAD) is an enzyme responsible for the synthesis of gamma-aminobutyric acid (GABA) from glutamic acid (Glu), a key balance between neurotransmitters in the central and peripheral nervous systems. The study aimed to investigate the effects of stress and Glu on the GAD concentrations in rabbit brain structures, revealing varying levels of the enzyme under different conditions, particularly in response to stress. The study highlighted the potential impact of glutamate receptor activity on GAD concentrations and suggested the importance of further research on the Glu-GAD-GABA system in stress and homeostasis modulation.

Summary: N-oleoylglycine and N-oleoylalanine reduce the rewarding properties of palatable food, dopamine neuron firing, and the obesogenic effect of a high-fat diet by activating PPAR alpha. Olive oil-rich diets can also decrease weight gain by increasing oleoylglycine levels and enhancing gut microbial diversity.

Summary: This review focuses on the genetic and metabolic engineering of microorganisms for gamma-PGA production, including strategies to enhance raw materials utilization, precursor supply, gamma-PGA synthetase gene cluster, transcription regulation, cofactor regeneration, energy engineering, and blocking synthetic pathways of by-products. The expression of gamma-PGA synthetase, glutamate racemase, and gamma-PGA hydrolase were manipulated to obtain gamma-PGA with different configurations and molecular weights. The review also discusses the metabolic engineering of other hosts for high-level production of gamma-PGA.

Summary: Exogenous ethylene treatment significantly increased the levels of amino acids, especially umami amino acids, in Torreya grandis nuts. Glutamic and aspartic acids showed a 1.9-fold and 2.1-fold increase, respectively. Transcriptome analysis revealed differential expression of genes involved in alanine, aspartate, and glutamate metabolism. RT-qPCR confirmed upregulation of biosynthesis genes (TgGOGAT1, TgAATC1, TgAATC4) and suppression of degradation enzymes (TgGS2, TgGAD1, TgGAD3, TgASNS1) after ethylene treatment. Ethylene treatment appears to enhance umami taste-active amino acids and improve the quality of T. grandis nuts.

Summary: This study investigated the potential of glutamic acid (Glu) and poly-gamma-glutamic acid (gamma-PGA) biostimulants in enhancing the thermotolerance of Chinese cabbage under heat stress. The results showed that both Glu and gamma-PGA treatments improved the parameters of vegetative growth, gas exchange, and chlorophyll fluorescence. Moreover, these treatments increased the contents of total chlorophyll and carotenoid and reduced oxidative damage by enhancing the activity levels of antioxidant enzymes. Transcriptome analysis revealed that the expression levels of genes involved in various metabolic pathways were up-regulated by both Glu and gamma-PGA priming. Overall, Glu was found to be more effective than gamma-PGA in enhancing the thermotolerance of Chinese cabbage.

Summary: Immunotherapy has achieved significant success in treating cancer, but resistance to this treatment often occurs due to the complex metabolic networks in the tumor microenvironment. Metabolic checkpoints play a crucial role in regulating T cell development, differentiation, and function, as well as coordinating metabolic competition between tumor cells and infiltrating T cells. Thus, targeting metabolic checkpoints may enhance the efficacy of immunotherapy.

Summary: MyD88 in myofibroblasts plays a critical role in promoting hepatocellular carcinoma by affecting aerobic glycolysis in cancer cells. MyD88 deficiency in myofibroblasts attenuates liver fibrosis and liver cancer tissue. Mechanistically, MyD88 signaling in myofibroblasts increases the secretion of CCL20, which promotes aerobic glycolysis in cancer cells. This process is dependent on the CCR6 receptor and ERK/PKM2 signaling.

Summary: This study investigates the role and mechanisms of CD147 in paclitaxel resistance. It demonstrates that CD147 protects cancer cells from paclitaxel-induced apoptosis and interacts with the C-terminal tail of RanBP1 to regulate microtubule stability and dynamics as well as response to paclitaxel treatment. Targeting CD147 may be a potential strategy for preventing paclitaxel resistance.

Summary: In this study, the authors use a mouse model of rheumatoid arthritis (RA) and single-cell RNA sequencing to show that inducing ferroptosis and suppressing TNF signaling can reduce the number of fibroblasts in the synovium and improve experimental arthritis. They further identify two groups of fibroblasts with distinct susceptibility to ferroptosis and show that TNF signaling protects fibroblasts from ferroptosis through promoting cystine uptake and glutathione biosynthesis. Finally, the combination of low-dose ferroptosis inducer and TNF antagonist attenuates arthritis progression in the mouse model.

Summary: Immunotherapy targeting tumor-infiltrating lymphocytes has shown promising potential as a treatment for various cancers, but its efficacy varies across different cancer types and patients. The distribution of TIL-T and TIL-B cells and their interactions with the tumor microenvironment play a crucial role in determining the clinical outcomes. Understanding the prognostic significance of these factors can have important implications for cancer immunotherapy.

Summary: Major gaps in understanding the molecular mechanisms of colorectal cancer progression and mucosal repair have hindered therapeutic development for gastrointestinal disorders. TFF3 plays a crucial role in CRC progression and mucosal repair, with upregulated TFF3 predicting worse survival rates in CRC patients. The interaction between TFF3 and CD147 enhances CRC progression by activating STAT3 and PTGS2, leading to increased migration, proliferation, and invasion of cancer cells.

The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.
