Insights

Targeting tumor metabolism with fatty acid synthase (FASN) inhibitors is a promising new cancer therapy. Newer FASN inhibitors are advancing, with some entering clinical trials for cancer treatment.

Area of Science:

  • Oncology
  • Cancer Metabolism
  • Drug Development

Background:

  • Cancer cells rely on lipid synthesis for growth and survival.
  • Fatty acid synthase (FASN) is crucial for producing lipids, making it a key oncologic target.
  • Targeting tumor metabolism represents a novel therapeutic strategy in oncology.

Purpose of the Study:

  • To review the role of FASN in cancer.
  • To discuss the development of FASN inhibitors as anticancer therapies.
  • To highlight the potential of FASN inhibition in clinical settings.

Main Methods:

  • Review of preclinical and clinical studies on FASN inhibitors.
  • Analysis of the pharmacologic properties and side-effect profiles of FASN inhibitors.
  • Identification of novel FASN inhibitors in development.

Main Results:

  • Early-generation FASN inhibitors faced limitations in pharmacology and side effects.
  • A new generation of FASN inhibitors, including TVB-2640, is under investigation.
  • TVB-2640 is the only FASN inhibitor that has advanced to clinical trials.

Conclusions:

  • FASN inhibition is a promising therapeutic approach for cancer patients.
  • Combination therapies involving FASN inhibitors may offer enhanced efficacy.
  • Further clinical investigation of FASN inhibitors is warranted.

Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Amino Acid Biosynthetic Pathways01:29

Amino Acid Biosynthetic Pathways

Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

Biosynthesis of Lipids

Microbial membranes exhibit remarkable diversity in lipid composition, reflecting evolutionary adaptations to various environmental conditions. The three domains of life—Bacteria, Archaea, and Eukarya—synthesize membrane lipids through distinct biosynthetic pathways, leading to fundamental structural differences that impact membrane stability, function, and adaptability.Fatty Acid-Based Lipids in Bacteria and EukaryaBacteria and eukaryotes share a common fatty acid biosynthesis...

Respiration Pathways

Cellular respiration is a fundamental metabolic process that enables organisms to generate energy from organic molecules. One of its central pathways is the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle, which plays a crucial role in energy production and biosynthetic processes.Conversion of Pyruvate to Acetyl-CoAThe pyruvate generated from glycolysis undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, producing acetyl-CoA, one molecule of NADH, and one...

Lipid Catabolism01:25

Lipid Catabolism

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Synthesis of Phosphatidylcholine in the ER Membrane01:27

Synthesis of Phosphatidylcholine in the ER Membrane

The ER synthesizes lipids for building cell membranes and performing cellular functions such as energy storage and signaling. The lipid synthesis machinery embedded in the ER membrane primarily collects all reactants from the cytosol. Following synthesis, the secretory pathway and the ER contact sites distribute these lipids to other cellular organelles. Additionally, the energy-rich triacylglycerides are transported from the ER via lipid droplets.
The major components of all eukaryotic cell...
