Insights

Multicellular resistance (MR) in cancer occurs when cells stick together, making treatments less effective. This review explores how cell adhesion contributes to MR and suggests ways to overcome it in ascites tumors.

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • Multicellular resistance (MR) is a significant challenge in cancer therapy.
  • MR arises from cell-cell adhesion, particularly in three-dimensional culture models.
  • Understanding MR mechanisms is crucial for developing effective cancer treatments.

Purpose of the Study:

  • To review existing studies on multicellular resistance (MR).
  • To investigate the role of cell adhesion molecules in MR.
  • To propose strategies for overcoming MR in ascites tumors.

Main Methods:

  • Literature review of studies on intrinsic and acquired multicellular resistance.
  • Examination of cell adhesion molecules and their contribution to MR.
  • Analysis of in vitro three-dimensional culture models.

Main Results:

  • Multicellular resistance (MR) is observed at the multicellular level.
  • Cell adhesion is critical for recapitulating MR in vitro.
  • Cell adhesion molecules play a direct or indirect role in MR.

Conclusions:

  • Multicellular resistance (MR) poses a therapeutic challenge.
  • Cell adhesion is a key factor in MR development.
  • Targeting cell adhesion may offer a strategy to circumvent MR in ascites tumors.

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...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
Adherens Junctions are Dynamic
The endothelial cells...
Drug Absorption Mechanism: Carrier-Mediated Membrane Transport01:19

Drug Absorption Mechanism: Carrier-Mediated Membrane Transport

Certain large, lipid-insoluble drug molecules that resemble amino acids, peptides, or glucose, require specialized carrier proteins to facilitate their diffusion across cell membranes. This transport can occur through either facilitated diffusion, which does not require energy input, or active transport, which does require energy input.
Facilitated diffusion is a passive process that utilizes human Solute Carrier (SLC) transporters. These transporters bind to the drug, undergo structural...
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.

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport

Drugs need to permeate cell membranes to reach their target sites after administration. Orally administered drugs must transcend intestinal epithelial membrane barriers to infiltrate the systemic circulation. Drugs with a molecular weight of less than 500 Daltons diffuse through gaps between neighboring cells, called paracellular pathways.
However, most drugs use the transcellular route, traversing directly through the cell membranes via two mechanisms: passive and active transport. Passive...
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...
