1 Polyamines regulate intestinal epithelial restitution through TRPC1-mediated Ca2+ signaling by differentially modulating STIM1 and STIM2. Polyamines transient receptor potential cation channel subfamily C member 1 Homo sapiens
2 Here, we show that polyamines regulate intestinal epithelial restitution through TRPC1-mediated Ca(2+) signaling by altering the ratio of STIM1 to STIM2. Polyamines transient receptor potential cation channel subfamily C member 1 Homo sapiens
3 Induced STIM1/TRPC1 association by increasing polyamines enhanced Ca(2+) influx and stimulated epithelial restitution, while decreased formation of the STIM1/TRPC1 complex by polyamine depletion decreased Ca(2+) influx and repressed cell migration. Polyamines transient receptor potential cation channel subfamily C member 1 Homo sapiens
4 Induced STIM1/TRPC1 association by increasing polyamines enhanced Ca(2+) influx and stimulated epithelial restitution, while decreased formation of the STIM1/TRPC1 complex by polyamine depletion decreased Ca(2+) influx and repressed cell migration. Polyamines transient receptor potential cation channel subfamily C member 1 Homo sapiens
5 These results indicate that polyamines differentially modulate cellular STIM1 and STIM2 levels in IECs, in turn controlling TRPC1-mediated Ca(2+) signaling and influencing cell migration after wounding. Polyamines transient receptor potential cation channel subfamily C member 1 Homo sapiens
