Effects of increasing dietary palmitoleic acid compared with palmitic and oleic acids on plasma lipids of hypercholesterolemic men.

Journal of Lipid Research, 1994
Palmitoleic acid is a minor monounsaturated fatty acid in the human diet and in blood plasma. Because macadamia oil is at least one potentially large source of palmitoleic acid, we tested its effect on plasma lipid levels against two other dietary fatty ...

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Intestinal peroxisome proliferator‐activated receptor α‐fatty acid‐binding protein 1 axis modulates nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Abstract Background and Aims Peroxisome proliferator‐activated receptor α (PPARα) regulates fatty acid transport and catabolism in liver. However, the role of intestinal PPARα in lipid homeostasis is largely unknown. Here, intestinal PPARα was examined for its modulation of obesity and NASH. Approach and Results Intestinal PPARα was activated and fatty

Fatty acid desaturation in lung: inhibition by unsaturated fatty acids

Journal of Lipid Research, 1980
The activity of the enzyme system involved in desaturation of palmitic and stearic acid has been examined in lungs of rats fed fat-free diets supplemented either with 4% safflower oil (controls) or 4% tripalmitin (essential fatty acid (EFA) deficient ...

Regulating PPARG Reduces Lipid Accumulation in Microglia and Promotes Functional Recovery After Spinal Cord Injury

Advanced Science, EarlyView.
Macrophages infiltrate the spinal cord post‐injury, decreasing over time. Microglia phagocytose myelin debris, increasing lipid accumulation. Macrophage deletion improves outcomes, while microglial deletion worsens them. The LD+ microglia subtype shows abnormal Pparg signaling.

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

Hepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

Advanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

Stages of uptake and incorporation of micellar palmitic acid by hamster proximal intestinal mucosa

Journal of Lipid Research, 1972
The stages of uptake and incorporation of micellar palmitic acid by hamster proximal intestinal mucosa were investigated by incubation of everted sacs at 4°C and 37°C for 2, 5, 10, and 15 min in a micellar solution (10 μmoles of [l-14C]palmitic acid, 10 ...

Acetylation of the Mitochondrial Chaperone GRP75 Governs ER‐Mitochondrial Calcium Homeostasis and Hepatocyte Insulin Resistance

Advanced Science, EarlyView.
Overnutrition exacerbates insulin resistance (IR) and is linked to excessive mitochondrial protein acetylation. However, it remains unclear whether and how mitochondrial protein acetylation influences IR. GCN5L1‐dependent downregulation of GRP75 acetylation at K567/612 consequently enhances ER‐mitochondrial calcium flux and induces ER stress.

Nonalcoholic Fatty Liver Disease Exacerbates the Advancement of Renal Fibrosis by Modulating Renal CCR2+PIRB+ Macrophages Through the ANGPTL8/PIRB/ALOX5AP Axis

Advanced Science, EarlyView.
The ANGPTL8/PIRB/ALOX5AP axis mediates liver‐kidney crosstalk. Hepatocytes secrete ANGPTL8, which binds to CCR2+PIRB+ macrophages in the kidneys, affecting the expression of ALOX5AP and enhancing the activation of these macrophages. Activated cells produce TGF‐β, IL‐6, and IL‐23, driving Th17 activation and promote the formation of myofibroblasts ...
