Insights

Targeting abnormal metabolism offers new pharmaceutical strategies for hepatocellular carcinoma (HCC) treatment. This review highlights key metabolic pathways and agents for developing effective HCC therapies.

Area of Science:

  • Hepatology
  • Oncology
  • Metabolic Research

Background:

  • Hepatocellular carcinoma (HCC) is a prevalent and aggressive cancer with increasing global incidence.
  • Current HCC treatments like chemotherapy face limitations such as chemoresistance.
  • Tumor development is significantly influenced by metabolic reprogramming, particularly in liver cancer.

Purpose of the Study:

  • To review pharmaceutical interventions targeting metabolic pathways in HCC.
  • To highlight key metabolic targets in glucose, fatty acid, amino acid, and glutamine metabolism for HCC therapy.
  • To discuss current agents and future opportunities in developing metabolism-targeted HCC treatments.

Main Methods:

  • Literature review of pharmaceutical therapies for HCC.
  • Analysis of metabolic reprogramming in HCC pathogenesis.
  • Summary of current research on agents targeting deregulated metabolism in HCC.

Main Results:

  • Metabolic pathways, including glucose, fatty acid, amino acid, and glutamine metabolism, are crucial in HCC.
  • Abnormal metabolism presents viable targets for novel pharmaceutical interventions in HCC.
  • Existing studies show promise in targeting deregulated metabolism for HCC treatment.

Conclusions:

  • Targeting aberrant metabolism represents a promising therapeutic avenue for hepatocellular carcinoma.
  • Further research into metabolic targets and agents is essential for advancing HCC treatment strategies.
  • Addressing metabolic dysregulation may overcome limitations of current HCC therapies, such as chemoresistance.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Liver Physiology

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
