The bile salt content of human bile impacts on simulated intestinal proteolysis of β-lactoglobulin.

Food Res Int 2021 Jul 12;145:110413. Epub 2021 May 12.

Gdańsk University of Technology, Faculty of Chemistry, Department of Colloid and Lipid Science, Gabriela Narutowicza 11/12, 80-322 Gdańsk, Poland. Electronic address:

The gastrointestinal hydrolysis of food proteins has been portrayed in scientific literature to predominantly depend on the activity and specificity of proteolytic enzymes. Human bile has not been considered to facilitate proteolysis in the small intestine, but rather to assist in intestinal lipolysis. However, human bile can potentially influence proteins that are largely resistant to gastric digestion, and which are mainly hydrolysed after they have been transferred to the small intestine.

Food Res Int 2021 Jul 7;145:110386. Epub 2021 May 7.

Institute of Food Sciences, CNR, Avellino, Italy; E.L.F.I.D, University "Federico II" Napoli, Italy. Electronic address:

Scope: Several studies reported a role of amylase/trypsin-inhibitors (ATIs) of common wheat species in promoting immune reactions. Here, we investigated in celiac disease (CD), the immunogenic properties of ATIs from diploid compared to common hexaploid wheats after an in vitro proteolytic hydrolysis.

Methods And Results: ATIs purified from two lines of diploid Triticum monococcum (TM), Monlis and Norberto-ID331, and from Triticum aestivum (TA), Sagittario, were digested with pepsin-chymotrypsin (PC) enzymes and analyzed using a proteomic approach, and subsequently their immune stimulatory properties were investigated on jejunal biopsies and T-cell lines from CD patients.

Targeting SNARE-Mediated Vesicle Transport to Block Invadopodium-Based Cancer Cell Invasion.

Front Oncol 2021 21;11:679955. Epub 2021 May 21.

Department of Molecular and Cellular Biology, University of Guelph, Guelph, ON, Canada.

During metastasis, cancer cells can invade extracellular matrix (ECM) through a process mediated by matrix-degrading protrusions of the plasma membrane, termed invadopodia. Formation of invadopodia correlates with cells' invasive and metastatic potential, and thus presents a potential target for therapeutic approaches to target metastatic progression. Invadopodia formation is dependent on the recruitment of proteins involved in intracellular signaling, actin cytoskeleton remodeling, and proteolytic matrix modification. Read More

An Undiagnosed Case of Chronic Pancreatitis With Multiple Visceral Arteries Pseudoaneurysm.

Cureus 2021 May 1;13(5):e14789. Epub 2021 May 1.

General Medicine, Rehman Medical Institute, Peshawar, PAK.

Visceral artery aneurysms, which could be either true or pseudo, are abnormal focal dilations of vessels supplying the abdominal organs. True aneurysms, by definition, suggest dilation of the vessel in response to increased blood flow, ultimately causing a blood-filled sac to form. Pseudoaneurysm, however, is the pooling of blood in surrounding tissues secondary to trauma or rupture. Read More

UBE4B, a microRNA-9 target gene, promotes autophagy-mediated Tau degradation.

Nat Commun 2021 06 2;12(1):3291. Epub 2021 Jun 2.

Metabolism and Neurophysiology Research Group, KRIBB, Daejeon, Korea.

The formation of hyperphosphorylated intracellular Tau tangles in the brain is a hallmark of Alzheimer's disease (AD). Tau hyperphosphorylation destabilizes microtubules, promoting neurodegeneration in AD patients. To identify suppressors of tau-mediated AD, we perform a screen using a microRNA (miR) library in Drosophila and identify the miR-9 family as suppressors of human tau overexpression phenotypes.
