  I consider production of heavy quarks in pA and AA collisions in the
framework of the Color Glass Condensate. I discuss the heavy quark production
in pA collisions in a classical approximation which takes into account all
multiple rescatterings of a proton in a nucleus. For peripheral collisions,
heavy quark production cross section can be written in $k_T$-factorized form.
The $k_T$ factorization is used to construct a simple model which takes into
account both classical and quantum effects in pA and AA collisions. I review
the main result of calculation based on that model: open charm in the central
rapidity region at RHIC gets suppressed as a function of rapidity. Although the
numbers obtained for the suppression factor are model dependent, the very fact
of suppression is the general feature of the Color Glass Condensate at RHIC
kinematical region. It indicates the onset of quantum evolution effects in a
nucleus and is universal for all inclusive processes.
