FIG. 1.

Telomerase activity and relative expression of telomerase subunit genes during MDV strain RB-1B (MDV-RB-1B) infection. Eight-week-old chickens were inoculated intramuscularly with 1,000 PFU of highly oncogenic MDV strain RB-1B. Telomerase activity and gene expression were analyzed on days 1, 7, 14, 21, and 27 postinfection, using PBMC from infected and control chickens. Means and standard deviations are given. Values for infected chickens significantly different from those for control chickens are indicated by an asterisk.
