Summary

Peroxisome proliferator-activated receptor (PPAR) influences lipid and glucose balance. This review explores PPAR's role in nonalcoholic steatohepatitis (NASH) pathogenesis, highlighting its potential therapeutic implications.

Area of Science:

  • Endocrinology
  • Metabolic Syndrome Research
  • Hepatology

Background:

  • Peroxisome proliferator-activated receptor (PPAR) is crucial for lipid and glucose homeostasis.
  • PPAR isoforms (PPARα, PPARγ) are key regulators in hepatocytes and adipocytes.
  • Emerging evidence links PPAR to inflammation, cell division, and liver disease progression.

Purpose of the Study:

  • To review the current understanding of PPAR's involvement in nonalcoholic steatohepatitis (NASH).
  • To explore the relationship between PPAR and the development or worsening of NASH.
  • To summarize existing evidence on PPAR and NASH for future therapeutic strategies.

Main Methods:

  • Literature review of studies investigating PPAR and NASH.
  • Analysis of evidence from animal models, including PPARα-deficient mice.
  • Examination of clinical data on PPARγ activator (pioglitazone) in NASH patients.

Main Results:

  • PPARα deficiency prevented NASH development in a mouse model.
  • Long-term pioglitazone administration improved NASH activity.
  • PPAR signaling pathways are implicated in NASH pathogenesis.

Conclusions:

  • PPAR plays a significant role in NASH development and progression.
  • Targeting PPAR pathways may offer therapeutic benefits for NASH.
  • Further research is needed to fully elucidate PPAR's role in NASH.
