Summary
This study investigates how water moves through Sodium Glucose Cotransporter 1 (SGLT1) and how sugar uptake inhibitors affect this process. Molecular dynamics simulations reveal SGLT1
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Sodium glucose cotransporters (SGLTs) facilitate glucose/galactose and sodium uptake across epithelial cells.
- SGLT1 is a key target for antidiabetic drug development and is crucial for oral rehydration therapy.
- While SGLT1's role in water absorption is known, the precise mechanisms and inhibitor effects remain unclear.
Purpose of the Study:
- To elucidate the influence of sugar uptake inhibitors on SGLT1's water transport.
- To determine the impact of inhibitor-induced changes in SGLT1's energetic and dynamic properties on water permeation.
Main Methods:
- Utilizing comprehensive molecular dynamics simulations.
- Analyzing energetic and dynamic properties of SGLT1 under the influence of inhibitors.
Main Results:
- Detailed insights into the mechanism of water transport through SGLT1.
- Understanding how inhibitors like phlorizin affect water permeation by altering SGLT1 dynamics.
Conclusions:
- SGLT1's water transport mechanism is significantly influenced by sugar uptake inhibitors.
- Molecular dynamics simulations provide a powerful tool for understanding SGLT1 function and inhibitor interactions.

22.9K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:26Glucose Absorption Into the Small Intestine
31.8K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

01:32Secondary Active Transport
7.2K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme "pump" embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

01:23Transcellular Transport of Solutes
3.6K
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...

01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
208
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

212
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...
