We study top-(anti)quark pair production at the Tevatron and Large Hadron Collider (LHC) in the context of the Minimal Length Scenario (MLS) of the Arkani-Hamed, Dimopoulos and Dvali (ADD) model of extra dimensions (XDs). We show that sizable effects onto both the integrated and differential cross section due to graviton mediation are expected for a String scale, M_S, of O(1-10TeV) and several XDs, \delta, all compatible with current experimental constraints. Potential limits on M_S are extracted. We also highlight clear phenomenological differences between a simple ADD scenario and its modification based on using the MLS as a natural regulator for divergent amplitudes of virtual KK graviton exchange.
