Pemafibrate, a selective PPARα modulator, effectively treats high triglycerides and low HDL-C. It enhances fatty acid metabolism and shows anti-inflammatory effects, benefiting patients with dyslipidemia and diabetic complications.
Area of Science:
- Biochemistry
- Pharmacology
- Molecular Biology
Background:
- Pemafibrate is the first selective peroxisome proliferator-activated receptor α modulator (SPPARMα) available.
- It effectively improves hypertriglyceridemia and low high-density lipoprotein cholesterol (HDL-C).
Purpose of the Study:
- To elucidate the molecular mechanisms of pemafibrate action on lipid metabolism and nutrient flux.
- To investigate the effects of pemafibrate on gene expression in human hepatocytes and vascular endothelial cells.
Main Methods:
- Global gene expression analysis in mouse liver and human hepatocytes.
- Analysis of specific gene induction, including HMGCS2, PDK4, ABCA1, FGF21, and VLDLR.
- Assessment of anti-inflammatory effects in vascular endothelial cells.
Main Results:
- Pemafibrate activation of PPARα induces fatty acid uptake, oxidation, and ketogenesis in mouse liver.
- In human hepatocytes, pemafibrate profoundly induces HMGCS2 and PDK4, key regulators of ketogenesis and glucose oxidation.
- Pemafibrate upregulates beneficial genes (ABCA1, FGF21, VLDLR) and exhibits anti-inflammatory effects.
Conclusions:
- PPARα activation by pemafibrate plays a crucial role in regulating nutrient flux in the human liver.
- Pemafibrate demonstrates potential therapeutic benefits for atherogenic dyslipidemia and diabetic microvascular complications.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Peroxisomes
Protein Import into the Peroxisomes
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
