Insights

Naringenin protects against doxorubicin-induced liver damage by reducing oxidative stress and inflammation. This study shows naringenin as a potential therapeutic agent for mitigating chemotherapy side effects.

Area of Science:

  • Biochemistry
  • Pharmacology
  • Toxicology

Background:

  • Doxorubicin (Dox) is a vital chemotherapy drug with dose-dependent hepatotoxicity.
  • Antioxidants show promise in mitigating Dox-induced liver injury.

Purpose of the Study:

  • To investigate the protective effects of naringenin against Dox-induced hepatotoxicity in Wistar rats.
  • To elucidate the mechanisms underlying naringenin's potential hepatoprotective action.

Main Methods:

  • Rats received prophylactic naringenin (50 and 100 mg/kg) orally for 20 days before a single Dox injection.
  • Hepatotoxicity was assessed via lipid peroxidation (MDA), antioxidant enzymes (CAT, GR, SOD, GPx, GSH), ROS levels, inflammatory markers (Cox-2, NF-κB), and liver histology.

Main Results:

  • Naringenin significantly reduced reactive oxygen species (ROS) production and lipid peroxidation.
  • It replenished antioxidant enzyme levels (CAT, GR, SOD, GPx, GSH) and decreased inflammatory mediators (Cox-2, NF-κB).
  • Histological analysis confirmed naringenin's protective effects on liver tissue.

Conclusions:

  • Oxidative stress and inflammation are key contributors to Dox-induced liver damage.
  • Naringenin demonstrates significant potential in preventing Dox-induced hepatotoxicity, likely by combating oxidative stress and inflammation.

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
