Pore Transport and Ion-Pair Transport01:17

Pore Transport and Ion-Pair Transport

Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
The Significance of Membrane Transport01:44

The Significance of Membrane Transport

The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...

Membrane Transporters01:31

Membrane Transporters

Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all genes in the human genome code for transporters or transporter-related proteins.
Transporters are mainly composed of alpha-helices, built from bundles of ten or more helices traversing the plasma membrane. The solute-binding sites are located midway, where some of the helices are broken or distorted, making space for the binding site through...
Membrane Proteins01:30

Membrane Proteins

Plasma membranes have integral transmembrane proteins involved in facilitated transport. These proteins are collectively referred to as transport proteins, and they function as either channels for the material or as carriers themselves. Channel proteins have hydrophilic domains exposed to the intracellular and extracellular fluids and a hydrophilic channel through their core that provides a hydrated opening for solutes to pass through the membrane layers. Passage through the channel allows...
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...

  • Cell Biology
  • Molecular Biology

Background:

  • Membrane transporters (MTs) play a critical role in drug disposition and response.
  • Two major MT superfamilies in mammals are ATP-binding cassette (ABC) and solute carrier (SLC) transporters.
  • Polyamines (PAs) are essential polycations involved in cellular processes, and their transport is mediated by specific systems.

Purpose of the Study:

  • To review eight SLC transporters and discuss their potential role in mediating polyamine (PA) transport in human cells.
  • To explore the involvement of known MTs in the polyamine transport system (PTS).

Main Methods:

  • Discussion of preliminary data on the role of SLC22A1 in PA uptake and MDR1 in PA-like molecule efflux.

Main Results:

  • Preliminary data suggest SLC22A1 may be involved in polyamine (PA) uptake.
  • The MDR1 protein, an ABC superfamily member, may mediate the efflux of polyamine-like molecules.
  • Several SLC transporters are identified as potential mediators of PA transport.

Conclusions:

  • Specific SLC transporters, including SLC22A1, are potential candidates for mediating polyamine (PA) transport in human cells.
  • Understanding these transporters is crucial for comprehending PA homeostasis and its implications in health and disease.
  • Further research is needed to fully elucidate the mechanisms of PA transport by MTs.
