Structural Dynamics of Neutral Amino Acid Transporter SLC6A19 in Simple and Complex Lipid Bilayers.

B0AT1 (SLC6A19) is a major sodium-coupled neutral amino acid transporter that relies on angiotensin converting enzyme 2 (ACE2) or collectrin for membrane trafficking. Despite its significant role in disorders associated with amino acid metabolism, there is a deficit of comprehensive structure-function understanding of B0AT1 in lipid environment. Herein, we have employed molecular dynamics (MD) simulations to explore the architectural characteristics of B0AT1 in two distinct environments: a simplified POPC bilayer and a complex lipid system replicating the native membrane composition.

Type 2 Usher Syndrome - A Cause for Sensorineural Hearing Loss.

Usher syndrome is a genetic condition involving Sensorineural hearing loss and Retinitis pigmentosa (RP). Although considered a rare disease, it is the most frequent cause of deaf- blindness in humans. It is inherited in an autosomal recessive pattern.

Natural product-inspired [3 + 2] cycloaddition-based spirooxindoles as dual anticancer agents: synthesis, characterization, and biological evaluation by and methods.

Breast and colorectal cancers are the most common tumors, with high recurrence and low survival rates. We designed and synthesized a series of spirooxindole pyrrolidinyl derivatives, which were further evaluated for anti-proliferative activity using MDA-MB-468 and HCT 15 cell lines. The best inhibitor of this class, compound 6f, showed a very good inhibition potency, both on the MDA-MB-468 and HCT 15 cells as confirmed by molecular docking and molecular dynamic studies that predicted its binding mode into the active site of the targets.

From sugar binders to diabetes fighters: the lectin saga of antihyperglycemic activity through systematic review and meta-analysis.

Introduction: Lectins are carbohydrate-binding proteins that are extremely selective for sugar groups in the other molecules. As a result, they perform a variety of roles in biological processes involving cell, carbohydrate, and protein recognition at the cellular and molecular levels. Because lectins can bind to carbohydrates, they may play a role in determining the rate of carbohydrate digestion.
