TERT-immortalized primary human fetal foreskin fibroblasts (HFFF-TERTs) were infected with HCMV strain Merlin at a multiplicity of infection (MOI) of 10 for 48 h, with application of MG132 (or the equivalent amount of dimethyl sulfoxide (DMSO) as a control) for the final 12 h of infection (Fig. 2A). Here, TERT is linked to infection.
