The nonperturbative properties of gauge theories in AdS4 are studied in dual supergravity by including light flavor quarks, which are introduced by a D7-brane embedding. Contrary to the Minkowski and dS4, the dilaton does not play any important dynamical role in the AdS4 case, and the characteristic properties like quark confinement and chiral symmetry breaking are realized mainly due to the geometry AdS4. The possible hadron spectra are also examined, and we find that the meson spectra are well described by the formula given by the field theory in AdS4, but the characteristic mass scale is modified by the gauge interactions for excited states.
