Insights

Peroxisome proliferator-activated receptor (PPAR) β/δ activators show promise in combating obesity-induced insulin resistance and type 2 diabetes mellitus (T2DM). These compounds may also improve dyslipidemia and cardiovascular disease risk.

Area of Science:

  • Metabolic diseases
  • Pharmacology

Background:

  • Insulin resistance is a precursor to dyslipidemia and type 2 diabetes mellitus (T2DM).
  • Peroxisome proliferator-activated receptor (PPAR) β/δ activators have shown potential in preclinical and clinical studies for metabolic disorders.

Purpose of the Study:

  • To review the mechanistic insights into the antidiabetic effects of PPARβ/δ activators.
  • To examine findings from clinical trials regarding PPARβ/δ activators' efficacy in T2DM and dyslipidemia.

Main Methods:

  • Review of preclinical evidence on PPARβ/δ activators.
  • Analysis of clinical trial data on PPARβ/δ activators.
  • Summary of mechanistic studies on PPARβ/δ actions.

Main Results:

  • PPARβ/δ activators exhibit anti-inflammatory effects and inhibit endoplasmic reticulum (ER) stress.
  • These activators reduce hepatic lipogenesis and improve insulin sensitivity.
  • PPARβ/δ activation mimics pathways stimulated by exercise and may improve atherogenesis.

Conclusions:

  • PPARβ/δ activators offer a potential therapeutic strategy for T2DM and associated dyslipidemia.
  • Understanding PPARβ/δ ligand effects on insulin sensitivity and atherogenesis is crucial for developing new treatments.
  • Targeting PPARβ/δ may help prevent and treat T2DM and cardiovascular disease (CVD).

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...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Adrenergic Receptors: β Subtype01:26

Adrenergic Receptors: β Subtype

β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

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...
