Summary
Sirtuin 1 (SIRT1), a metabolic sensor, improves insulin sensitivity in key tissues. This suggests SIRT1 is a potential therapeutic target for insulin resistance diseases like type 2 diabetes.
Area of Science:
- Biochemistry
- Metabolic Regulation
- Molecular Biology
Background:
- Sirtuin 1 (SIRT1) is a key mammalian NAD(+)-dependent protein deacetylase.
- SIRT1 functions as a crucial metabolic sensor in various tissues.
- Emerging evidence links SIRT1 to the regulation of glucose and lipid metabolism.
Purpose of the Study:
- To review recent advancements in SIRT1 research.
- To focus on SIRT1's role in insulin resistance across metabolic tissues.
- To explore SIRT1 as a potential therapeutic target.
Main Methods:
- Literature review of recent SIRT1 research.
- Analysis of SIRT1's impact on insulin sensitivity.
- Examination of SIRT1's effects on pancreatic beta-cells.
Main Results:
- Activated SIRT1 enhances insulin sensitivity in the liver, skeletal muscle, and adipose tissue.
- SIRT1 activation protects the function and cell mass of pancreatic beta-cells.
- SIRT1 plays a significant role in mitigating insulin resistance.
Conclusions:
- SIRT1 activation improves insulin sensitivity in critical metabolic tissues.
- SIRT1 is a promising therapeutic target for insulin resistance-related diseases.
- Targeting SIRT1 could aid in preventing metabolic syndrome and type 2 diabetes mellitus.

01:28Insulin: The Receptor and Signaling Pathways
6.1K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
959
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

01:22PI3K/mTOR/AKT Signaling Pathway
6.3K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
3.1K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:23Dipeptidyl Peptidase 4 Inhibitors
1.1K
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...
