Bile acids play a major role in the regulation of lipid and energy metabolism. Here we propose the hepatic bile acid uptake transporter Na+ taurocholate cotransporting polypeptide (NTCP) as a target to prolong postprandial bile acid elevations in plasma. R ...
In ectotherms, increased ambient temperature requires the organism to consume substantial amounts of energy to sustain a higher metabolic rate, prevent cellular damage, and respond to heat stress. Here, we identify a heat-inducible apolipoprotein required ...
Modern methods for counting people in crowded scenes rely on deep networks to estimate people densities in individual images. As such, only very few take advantage of temporal consistency in video sequences, and those that do only impose weak smoothness co ...
In specialized cell types, lysosome-related organelles support regulated secretory pathways, whereas in nonspecialized cells, lysosomes can undergo fusion with the plasma membrane in response to a transient rise in cytosolic calcium. Recent evidence also i ...
Mendelian randomization is the use of genetic variants to assess the effect of intervening on a risk factor using observational data. We consider the scenario in which there is a pharmacomimetic (i.e., treatment-mimicking) genetic variant that can be used ...
Objective The management of occult lymph node metastasis (LNM) in head and neck squamous cell carcinoma has been a matter of controversy for decades. The vascular density within the tumor microenvironment, as an indicator of ongoing angiogenesis, could con ...
Most cells acquire cholesterol by endocytosis of circulating low-density lipoproteins (LDLs). After cholesteryl ester de-esterification in endosomes, free cholesterol is redistributed to intracellular membranes via unclear mechanisms. Our previous work sug ...
Background: Low-density lipoproteins (LDL) were used as a natural drug delivery system for the transport of hypericin (Hyp) in the bloodstream of the chicken's chorioallantoic membrane model (CAM). Hyp was chosen as a model for hydrophobic drug used in pho ...
Meticulous observations of the cell perinuclear region where the Golgi and the endoplasmic reticulum (ER) networks intermingle have revealed close contact sites of barely 20 nm between these two organelles. Recent studies demonstrate that molecular machine ...
The development of fluorescence-based molecular imaging has revolutionized cell biology allowing the visualization of specific biomolecules at the microscopic and, more recently, at the nanoscopic scale while in their relevant biological contexts. Nonethel ...
