Unintegrated parton distributions in the proton and nucleus are predicted by a modified Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) equation incorporating the shadowing corrections, which include exact energy-momentum conservation in each splitting and fusion vertices. We find that the nuclear shadowing effects are obvious, although they are far from the saturation limit. On the other hand, we point out that the suppression of the unintegrated gluon distribution toward lower k{sub t}{sup 2} may arise from the valence-like input rather than the saturation effects.
