Insights

Insulin promotes glucose metabolism by inhibiting microRNA-593-3p (miR-593-3p). This action upregulates Slc38a1 and CLIP3, revealing a novel mechanism for insulin-regulated glycolysis.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • Insulin is crucial for glucose metabolism, but its molecular regulation remains incompletely understood.
  • MicroRNAs (miRNAs) are emerging as key regulators in various cellular processes, including metabolism.

Purpose of the Study:

  • To elucidate the role of miR-593-3p in insulin-regulated glucose metabolism.
  • To identify novel targets of miR-593-3p involved in this process.

Main Methods:

  • Utilized hepatocellular carcinoma cell lines (HepG2 and Bel7402).
  • Investigated the regulatory effects of miR-593-3p on glucose metabolism.
  • Identified and validated Slc38a1 and CLIP3 as direct targets of miR-593-3p.

Main Results:

  • miR-593-3p was found to negatively regulate insulin-induced glucose metabolism.
  • Slc38a1 and CLIP3 were identified as novel targets of miR-593-3p.
  • Insulin treatment downregulated miR-593-3p, leading to increased Slc38a1 and CLIP3 expression and enhanced glucose metabolism.

Conclusions:

  • Insulin promotes glycolysis by downregulating miR-593-3p.
  • Slc38a1 and CLIP3 mediate the effects of insulin on glucose metabolism.
  • This study provides new insights into the molecular mechanisms of insulin-induced glycolysis.

Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

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...

Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

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.
Insulin and C-peptide are...
