Summary: Fat metabolism is an important process in meat production companies, which affects the quality of meat. The source and incorporation rate of fat differ in different growth phases. The liver plays a critical role in fat metabolism during the fattening phase. Leaner pigs rely more on dietary fatty acids for fat deposition compared to fatter pigs. The activity of stearoyl-CoA desaturase is higher in the fattening phase.

Summary: A photocatalytic technique has been developed for in situ mass spectrometric identification and spatial imaging of positional isomers of lipids. It involves the use of gold nanowires to transfer plasmonic hot electrons, generating hydroxyl radicals that cause bond cleavages. The technique can determine the locations of C=C bonds through diagnostic fragment ions produced by collision or auto-fragmentation.

Summary: Disturbances in lipid metabolism caused by excessive food intake and a sedentary lifestyle are major risks for metabolic disorders. The enzyme SCD1 plays an important role in these diseases by catalyzing the synthesis of unsaturated fatty acids. Studies have shown that increased activity or over-expression of SCD1 is a contributing factor for type 2 diabetes mellitus. This research investigated the impact of a common genetic variant on SCD1 function and found that the variant could contribute to the development of obesity-related metabolic disorders, including type 2 diabetes mellitus, by increasing intracellular levels of SCD1.

Summary: Currently, there is no preventive or disease-modifying therapy available for Parkinson's Disease (PD). The failure of clinical trials calls for a re-evaluation of pre-clinical models that better replicate disease mechanisms and predict clinical outcomes. Patient-derived induced pluripotent stem cell (iPSC) models have recently emerged as attractive options to mimic disease-relevant neuropathology in vitro without artificially overexpressing disease-related proteins. In this study, iPSCs derived from early-onset PD patients with specific mutations were utilized to generate a three-dimensional cortical neurosphere model. The model showed alterations in fatty acid profiles and increased levels of pathogenic proteins, which could be attenuated by a small molecule inhibitor. These findings suggest that the 3D cortical neurosphere model is a useful tool for investigating PD and testing potential therapeutics.

Summary: This study systematically investigated the expression patterns and clinical outcomes of SCD1 in multiple human cancers and found that SCD1 is dysregulated in several types of cancers and acts as a diagnostic biomarker. Using ESCC as an example, it was found that SCD1 is upregulated in ESCC tumor tissues and is associated with clinicopathological characteristics and poor survival outcomes. Additionally, the study revealed the potential therapeutic target of the miR-181a-5p/SCD1 axis for ESCC treatment.

Summary: This study examined ethnic differences in serum fatty acid composition and desaturase indices among black and white South African women, finding that despite lower whole-body insulin sensitivity in black women, they exhibited a fatty acid pattern typically associated with higher insulin sensitivity in European populations. The results suggest that genetic factors may play a role in influencing fatty acid metabolism and insulin sensitivity among different ethnic groups.

Summary: The imbalance between pathogenic and protective T cell subsets is a key feature of autoimmune disorders such as multiple sclerosis (MS). The molecular mechanisms underlying the impact of fatty acid metabolism on T cell physiology and autoimmunity are poorly understood. The study reveals that fatty acid desaturation by SCD1 acts as an endogenous brake on regulatory T-cell differentiation and enhances autoimmunity, suggesting potential therapeutic strategies for autoimmune disorders such as MS.

Summary: Stearoyl-CoA desaturase (SCD) is a potential therapeutic target for Parkinson's and related neurodegenerative diseases. YTX-7739, a SCD inhibitor, effectively inhibits SCD in the brain and produces well-tolerated pharmacodynamic responses. It modulates the toxicity of α-synuclein by altering the ratio of fatty acids.

Summary: This study suggests that targeting MCL1 and BET may have therapeutic potential for the treatment of basal-like breast cancers. BET inhibition induces an adaptive response leading to the evasion of apoptosis in breast cancer cells driven by MCL1 protein. The mechanism involves upregulation of lipid synthesis enzymes, which affects cell motility and membrane fluidity, as well as the activation of HER2/EGFR signaling. MCL1 copy-number alterations are associated with the effectiveness of BET and MCL1 co-targeting.

Summary: Stem cell self-renewal and differentiation are regulated by metabolism, specifically lipid desaturation. Inhibiting specific metabolic enzymes can maintain stem cell characteristics and reduce cell apoptosis. Monounsaturated fatty acids are beneficial for stem cells but detrimental to trophoblast cells.
