Decay/Annihilation of Dark Matter particles in astrophysical environments produces besides gamma photons comparable amounts of protons, neutrinos and electrons (and their antiparticles). In particular electrons loose most of their energy through synchrotron and inverse Compton processes interacting with magnetic fields and interstellar radiation. I will describe the constraints achievable looking at this secondary radiation in particular in relation to the DM interpretation of the recent Pamela/Fermi e+e- anomalies. As second DM sensitive observable I will consider the anisotropies that DM would imprint in the gamma sky as a result of its anisotropic distribution at cosmological scales and, in the case of galactic DM, as a result of the presence of substructures in the Milky Way Galactic Halo. The sensitivity of the Fermi satellite to this channel will be also discussed.
