Insights

Drug resistance in cancer is a major challenge. This review explores how ATP binding cassette (ABC) transporters and lipid metabolism, particularly ceramide and sphingolipids, influence multidrug resistance and cellular response to anticancer agents.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Drug resistance is a significant obstacle in cancer therapy.
  • ATP binding cassette (ABC) transporters are key membrane proteins implicated in multidrug resistance.
  • ABC transporters also play roles in other diseases like malaria and leishmaniasis.

Purpose of the Study:

  • To review current understanding of ceramide, glucosylceramide synthase, and cerebrosides.
  • To elucidate the relationship between these lipids and cellular response to anticancer drugs.
  • To highlight the role of lipid metabolism in overcoming multidrug resistance.

Main Methods:

  • Literature review of current research on lipid metabolism and drug resistance.
  • Analysis of studies focusing on ceramide, glucosylceramide synthase, and cerebrosides.
  • Integration of findings on ABC transporters and their link to glycosphingolipids.

Main Results:

  • Glycosphingolipids, including ceramide and its derivatives, are increasingly recognized for their role in multidrug resistance.
  • Specific enzymes like glucosylceramide synthase are critical in modulating cellular lipid profiles and drug sensitivity.
  • Altering lipid metabolism pathways may offer novel strategies to combat cancer drug resistance.

Conclusions:

  • Lipid metabolism, particularly involving ceramide and sphingolipids, is intricately linked to cancer multidrug resistance.
  • Targeting lipid synthesis pathways presents a promising avenue for developing new anticancer therapies.
  • Further research into the precise mechanisms of glycosphingolipids in ABC transporter function is warranted.

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters01:16

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
Cellular Membranes and Drug Transport01:24

Cellular Membranes and Drug Transport

Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.
Carrier-Mediated Transport01:06

Carrier-Mediated Transport

Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
