The emergence and importance of hidden local symmetry in the structure ofhadrons under extreme conditions is discussed. The topics covered are thepotentially important role played by an infinite tower of vector mesons encodedin holographic dual QCD (or AdS/QCD) in chiral dynamics of mesons and baryons,in the vector dominance and its violation in EW response functions and thepresence of the vector manifestation fixed point and its influence on theproperties of hadrons in hot temperature (i.e., in relativistic heavy ioncollisions) and in dense matter (i.e., in compact stars). Also discussed arethe natural emergence of instantons/skyrmions from the infinite tower of vectormesons coupled to pions in AdS/QCD and their (speculated) role in chiralrestoration at high density.Comment: Based in part on talks given at The 1st Asian Triangle Heavy Ion Conference, 2006, Seoul, Korea and at The Yukawa International Seminar (YKIS), 2006, "New Frontiers in QCD", Kyoto, Japa
