WebIf the canonical Wnt signaling is activated, beta-catenin will translocate to the nucleus to associate with TCF/LEF transcription factors to activate transcription of Wnt target genes. Since this is a luciferase plasmid, you should see an increase in relative luciferase activity when substrate is added. jelica informatikajelica jeaWebHow does optogenetics work? Algae found in ponds and lakes contain light sensitive proteins called rhodopsins. These rhodopsins become active when exposed to light. For example, when a nerve cell containing rhodopsins is exposed to a certain colour of light, the rhodopsins becomes stimulated and change shape which in turn changes the activity ... jelica koršičWebMay 19, 2024 · Optogenetics combines optics, genetics, and virology to allow researchers to use light to control brain cells genetically engineered to respond to specific wavelengths.
