  The observed correlation between the EMC effect and the contribution of
short-range correlations (SRCs) in nuclei suggests that the modification of the
quark distributions of bound protons and neutrons might occur within SRCs. This
raises the possibility that the EMC effect may have an isospin dependence
arising from the np dominance of SRCs. We discuss previous attempts to test
this possibility and perform a new analysis of existing data. We find no
experimental support for the observation of an isospin dependence of the EMC
effect.
