Make Your Own Cell Survival Kit! - Synthetic glycopolymers in the membrane hold up programmed cell death

Latest News

Make Your Own Cell Survival Kit!

Synthetic glycopolymers in the membrane hold up programmed cell death.
Glycoproteins such as the mucins are assumed to be heavily involved in oncogenesis and metastasic spread. They are part of a strategy developed by malignant cells to resist or dodge the cell death machinery specialized for cells that show insufficient signaling through adhesions. Developing models for the mucins is very challenging, but American scientists have now synthesized glycopolymers that are not only recycled in the membrane, but also prolong the lifetime of healthy cells, as described in the journal Angewandte Chemie.
