Fatty Acylation of Synaptotagmin in PC12 Cells and Synaptosomes

Biochemical and Biophysical Research Communications, 1996
Synaptotagmin I is localized to synaptic vesicles where it functions in the calcium-triggered release of neurotransmitters. Here we demonstrate that synaptotagmin I covalently incorporated [3H]palmitate after metabolic labelling of PC-12 cells and rat brain synaptosomes.

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

Advanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

A Biomimetic cRGDyk‐Engineered Platelet Nanoplatform for ACAD11 Delivery to Trigger Pyroptosis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
A biomimetic platelet nanoplatform (OE‐ACAD11@R‐PLT) is developed for targeted hepatocellular carcinoma immunotherapy. By selectively delivering therapeutic plasmids, this system induces mitochondrial dysfunction and triggers robust NLRP3/Caspase‐1/GSDMD‐mediated pyroptosis in tumor cells.

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Metabolic crosstalk between roots and rhizosphere drives alfalfa decline under continuous cropping

Frontiers in Plant Science
Considerable biological decline of continuously cropped alfalfa may be tightly linked to rhizosphere metabolism. However, plant-soil feedbacks and age-related metabolic changes in alfalfa stands remain unexplored.

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

Advanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double‐blind, placebo‐controlled clinical trial

Hepatology, EarlyView., 2022
NRPT 1X reduces ALT and ceramide 14:0 in 65% of subjects as compared to only 28% in the placebo group. Abstract Background and Aims The prevalence of NAFLD is increasing globally and on a path to becoming the most frequent cause of chronic liver disease. Strategies for the prevention and treatment of NAFLD are urgently needed.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...
