Northwestern scientists have developed an artificial molecular pump, a device that simulates a mechanism allowing cells to metabolize and store energy. The pump could pave the way for future ...

Our cells move energy and matter to the places it is needed. But how do they do this in real time, and seen from the perspective of a single molecule? Scientists have successfully uncovered new ...

The new machine mimics the pumping mechanism of life-sustaining proteins that move small molecules around living cells to metabolize and store energy from food. For its food, the artificial pump ...

A Danish-British research team has discovered a turbo switch in the vital calcium pump in our body's cells. In studies at the X-ray source DORIS at Deutsches Elektronen-Synchrotorn DESY in Hamburg ...

Carrier proteins consume fuel in order to pump ions or molecules across cell membranes, creating concentration gradients. Their control over diffusion pathways, effected entirely through ...

Proteins charged with transportation across a cell's membrane tend to be picky, accepting only particular types of cargo, in some cases a single molecule. Sometimes cells resist medication by ...

Cells are actually able to get around the effects of medication by kicking it out; cancer cells are especially known for this striking behavior, with chemo | Cell And Molecular Biology. toggle ...

Scientists have made a breakthrough in the use of human muscle cells to 3D print a small heart pump. Researchers have known how to use genetic manipulation to reprogram adult cells so they will become ...

A cell requires functioning ribosomes to survive — but they are difficult to engineer. If the engineered molecules deviate too far from the standard design, the cell will die.

The proteins MmpL5 and MmpL4 are efflux transporters, critical pumps that help the pathogen M. tuberculosis grow by scavenging essential iron from the iron-deprived lung granulomas of its human host.

Low oxygen stops kidney cells making enough of a compound called adenosine triphosphate (ATP), which normally powers a molecular pump on their surface that keeps sodium levels low and potassium ...

Pgp is one of several molecular transporters that form the blood-brain barrier, a layer of cells that strictly limits the ability of many types of molecules --including many pharmaceuticals -- to ...
