An asymptotically safe theory of quantum gravity could render a non-perturbative renormalization of general relativity, restoring its predictive power at higher energies. Assuming such UV completion does exist, we can then ask whether quantum gravity fluctuations can induce (or spoil) fixed points present in pure-matter sectors. Furthermore, the interaction of gravity with matter sectors could allow us to extract imprints from the Planck scale to the energy scales accessible by experiments and observations. In this talk, I will explore this interplay between gravity and matter, focusing on two toy models inspired by ALPs and Horndeski-like theories.
