SGLT
Sodium-dependent glucose cotransporters (or sodium-glucose linked transporter, SGLT) are a family of glucose transporter found in the intestinal mucosa (enterocytes) of the small intestine (SGLT1) and the proximal tubule of the nephron (SGLT2 in PCT and SGLT1 in PST). They contribute to renal glucose reabsorption. In the kidneys, 100% of the filtered glucose in the glomerulus has to be reabsorbed along the nephron (98% in PCT, via SGLT2). If the plasma glucose concentration is too high (hyperglycemia), glucose passes into the urine (glucosuria) because SGLT are saturated with the filtered glucose. Types The two most well known members of SGLT family are SGLT1 and SGLT2, which are members of the SLC5A gene family. In addition to SGLT1 and SGLT2, there are 10 other members in the human protein family SLC5A. Of these, SLC5A4/SGLT3 (SAAT1) is a low-affinity transporter for glucose, but seems to have more of an electric function. The other SLC5 proteins transport mannose, my ...

Dapagliflozin
Dapagliflozin, sold under the brand names Farxiga (US) and Forxiga (EU) among others, is a medication used to treat type 2 diabetes. It is also used to treat adults with heart failure and chronic kidney disease. Common side effects include hypoglycaemia (low blood sugar), urinary tract infections, genital infections, and volume depletion (reduced amount of water in the body). Diabetic ketoacidosis is a common side effect in type 1 diabetic patients. Serious but rare side effects include Fournier gangrene. Dapagliflozin is a sodium-glucose co-transporter-2 (SGLT-2) inhibitor and works by removing sugar from the body with the urine. It was developed by Bristol-Myers Squibb in partnership with AstraZeneca. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 217th-most commonly prescribed medication in the United States, with more than 2million prescriptions. Medical uses Dapagliflozin is used along with diet, exercise, and usually with oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canagliflozin
Canagliflozin, sold under the brand name Invokana among others, is a medication used to treat type 2 diabetes.

SLC5A2
The sodium/glucose cotransporter 2 (SGLT2) is a protein that in humans is encoded by the (solute carrier family 5 (sodium/glucose cotransporter)) gene. Function SGLT2 is a member of the sodium glucose cotransporter family, which are sodium-dependent glucose transport proteins. SGLT2 is the major cotransporter involved in glucose reabsorption in the kidney. SGLT2 is located in the early proximal tubule, and is responsible for reabsorption of 80-90% of the glucose filtered by the kidney glomerulus. Most of the remaining glucose absorption is by sodium/glucose cotransporter 1 (SGLT1) in more distal sections of the proximal tubule. SGLT2 inhibitors for diabetes SGLT2 inhibitors are called gliflozins. They lead to a reduction in blood glucose levels, and therefore have potential use in the treatment of type II diabetes. Gliflozins enhance glycemic control as well as reduce body weight and systolic and diastolic blood pressure. The gliflozins canagliflozin, dapagliflozin, and ...

SLC5A1
Sodium/glucose cotransporter 1 (SGLT1) also known as solute carrier family 5 member 1 is a protein in humans that is encoded by the gene which encodes the production of the SGLT1 protein to line the Intestinal absorptive cells, absorptive cells in the small intestine and the epithelial cells of the kidney tubules of the nephron for the purpose of glucose uptake into cells. Through the use of the sodium glucose cotransporter 1 protein, cells are able to obtain glucose which is further utilized to make and store energy for the cell. Structure The sodium glucose cotransporter 1 is classified as an integral membrane protein that is made up of 14 alpha-helices constructed from the folding of 482-718 amino acid residues with both the N-terminal, N and C-terminal residing upon the extracellular side of the plasma membrane. It is hypothesized that the protein contains protein kinase A and protein kinase C phosphorylation sites, which serve to regulate the proteins conformational shape t ...

Secondary Active Transport
In cellular biology, ''active transport'' is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate ( ATP), and secondary active transport that uses an electrochemical gradient. Some examples of active transport include: * Phagocytosis of bacteria by macrophages * Movement of calcium ions out of cardiac muscle cells * Transportation of amino acids across the intestinal lining in the human gut * Secretion of proteins such as enzymes, peptide hormones, and antibodies from various cells * Functioning of white blood cells to defend invading diseases Active cellular transportation (ACT) Unlike passive transport, which uses the kinetic energy and natural entropy of molecules moving down a gradient, active ...

Glucose
Glucose is a simple sugar with the molecular formula . Glucose is overall the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, the most abundant carbohydrate in the world. In energy metabolism, glucose is the most important source of energy in all organisms. Glucose for metabolism is stored as a polymer, in plants mainly as starch and amylopectin, and in animals as glycogen. Glucose circulates in the blood of animals as blood sugar. The naturally occurring form of glucose is -glucose, while -glucose is produced synthetically in comparatively small amounts and is less biologically active. Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.

Renal Glucose Reabsorption
Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glycosuria. This is associated with diabetes mellitus. Firstly, the glucose in the proximal tubule is co-transported with sodium ions into the proximal convoluted tubule walls via the cotransporter. Some (typically smaller) amino acids are also transported in this way. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 2 Diabetes
Type 2 diabetes, formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, and unexplained weight loss. Symptoms may also include increased hunger, feeling tired, and sores that do not heal. Often symptoms come on slowly. Long-term complications from high blood sugar include heart disease, strokes, diabetic retinopathy which can result in blindness, kidney failure, and poor blood flow in the limbs which may lead to amputations. The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon. Type 2 diabetes primarily occurs as a result of obesity and lack of exercise. Some people are genetically more at risk than others. Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to type 1 diabetes and gestational diabetes. In type 1 diabete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symporter
A symporter is an integral membrane protein that is involved in the transport of two (or more) different molecules across the cell membrane in the same direction. The symporter works in the plasma membrane and molecules are transported across the cell membrane at the same time, and is, therefore, a type of cotransporter. The transporter is called a symporter, because the molecules will travel in the same direction in relation to each other. This is in contrast to the antiport transporter. Typically, the ion(s) will move down the electrochemical gradient, allowing the other molecule(s) to move against the concentration gradient. The movement of the ion(s) across the membrane is facilitated diffusion, and is coupled with the active transport of the molecule(s). In symport, two molecule move in 'similar direction' at the 'same time' Example of symport:- movement of glucose along with sodium ion Examples SGLT1 in the intestinal epithelium transports sodium ions (Na+) and glucose acro ...
