Title
Time-lapse FRET images of reporter HeLa cells and producer HeLa cells
Description
Time-lapse FRET images of Booster-PKA in reporter COX-DKO (COX-1 and COX-2 deficient)-HeLa cells cocultured with producer HeLa cells. In the producer cells, optogenetic calcium channel stimulator: OptoSTIM1 (CRY2clust) is expressed, and PGE2 (prostaglandin E2) is generated after blue light flash. It is released and binds to the EP2 on the reporter cells and induces the FRET of PKA biosensor, Booster-PKA. These serial processes reveal the coverage of PGE2 around one activated cell.
This dataset includs 5 files of serial imaging. The images of iRFP were obtained at the start and the end of the imaging showing the producer cells.

Biosample
Description
Co-culture of the producer cells and the reporter cells.
Producer cells; HeLa cells expressing OptoSTIM, R-GECO1 and iRFP670.
Reporter cells; COX-1 and COX-2 (COX-DKO)-deficient HeLa cells which express Gs-coupled EP2 receptor and Booster-PKA
MeSH
Fluorescence Resonance Energy Transfer (
D031541)
Intrinsic Variable
In the reporter cells, cyclooxygenases (COX1 and COX2) were knocked out by CRISPR/Cas9 to eliminate PGE2 synthesis.
Extrinsic Variable
OptoSTIM, R-GECO1 and iRFP670 were expressed in producer cells, and EP2 receptor and Booster-PKA were expressed in reporter cells.
