The evolution of galaxies can be thought as the result of the cumulative effects of two broad classes of processes: (i) secular (internal) processes determined by the very nature of galaxies, and (ii) external processes that are determined by the environment in which the object are embedded. In this talk I will face both aspects of galaxy evolution. On one hand, I will show that the presence of a stellar bar in massive disk galaxies can quench the star formation within the first kiloparsecs from their center. In particular I will report the consequences of the presence of a stellar bar on the distribution of the gaseous component of galaxies, their star formation and their optical colors. On the other hand, I will report the MUSE observations of three different systems in the nearby cluster Abell 1367 suffering from the interaction with the environment. Above all I will focus on the description of the kinematics and physical parameters of UGC 6697, a massive spiral galaxy suffering from an extreme ram pressure event.
