  Galaxies undergoing ram pressure stripping in clusters are an excellent
opportunity to study the effects of environment on both the AGN and the star
formation activity. We report here on the most recent results from the GASP
survey. We discuss the AGN-ram pressure stripping connection and some evidence
for AGN feedback in stripped galaxies. We then focus on the star formation
activity, both in the disks and the tails of these galaxies, and conclude
drawing a picture of the relation between multi-phase gas and star formation.
