ACSL1 is a key regulator of inflammatory and macrophage foaming induced by short-term palmitate exposure or acute high-fat feeding

iScience, 2023
Summary: Foamy and inflammatory macrophages play pathogenic roles in metabolic disorders. However, the mechanisms that promote foamy and inflammatory macrophage phenotypes under acute-high-fat feeding (AHFF) remain elusive.

The Effects of Temperature on Cellular Physiology.

Annual Review of Biophysics, 2022
Temperature impacts biological systems across all length and timescales. Cells and the enzymes that comprise them respond to temperature fluctuations on short timescales, and temperature can affect protein folding, the molecular composition of cells, and

Regulated adipose tissue-specific expression of human AGPAT2 in lipodystrophic Agpat2-null mice results in regeneration of adipose tissue

iScience, 2023
Summary: Genetic loss of Agpat2 in humans and mice results in congenital generalized lipodystrophy with near-total loss of adipose tissue and predisposition to develop insulin resistance, diabetes mellitus, hepatic steatosis, and hypertriglyceridemia ...

Adipocyte-derived chemerin rescues lipid overload-induced cardiac dysfunction

iScience, 2023
Summary: Chemerin, an adipocyte-secreted protein, has been recently suggested to be linked to metabolic syndrome and cardiac function in obese and diabetes mellitus.

A purinergic mechanism underlying metformin regulation of hyperglycemia

iScience, 2023
Summary: Metformin, created in 1922, has been the first-line therapy for treating type 2 diabetes mellitus for almost 70 years; however, its mechanism of action remains controversial, partly because most prior studies used supratherapeutic concentrations

Pitstop‐2 and its novel derivative RVD‐127 disrupt global cell dynamics and nuclear pores integrity by direct interaction with small GTPases

Bioengineering & Translational Medicine, 2023
Clathrin‐mediated endocytosis (CME) is an essential cell physiological process of broad biomedical relevance. Since the recent introduction of Pitstop‐2 as a potent CME inhibitor, we and others have reported on substantial clathrin‐independent inhibitory

Spatially coordinated collective phosphorylation filters spatiotemporal noises for precise circadian timekeeping

iScience, 2023
Summary: The circadian (∼24h) clock is based on a negative-feedback loop centered around the PERIOD protein (PER), translated in the cytoplasm and then enters the nucleus to repress its own transcription at the right time of day.

Regulation of glycolysis by the hypoxia‐inducible factor (HIF): implications for cellular physiology

Journal of Physiology, 2020
Under conditions of hypoxia, most eukaryotic cells can shift their primary metabolic strategy from predominantly mitochondrial respiration towards increased glycolysis to maintain ATP levels.

IL-1beta promotes the age-associated decline of beta cell function

iScience, 2021
Summary: Aging is the prime risk factor for the development of type 2 diabetes. We investigated the role of the interleukin-1 (IL-1) system on insulin secretion in aged mice.

In vitro cell models merging circadian rhythms and brain waves for personalized neuromedicine

iScience, 2022
Summary: New evidence is emerging about the dynamics of interaction between circadian rhythms and brain waves, whose coordination occurs through the entrainment process.
