A comparative analysis of microarray and RPA of a subset of genes increased in the liver after allogeneic BMT. (A) ICAM-1. (B) VCAM-1. (C) RANTES. (D) MCP-1. (E) Caspase-1. (F) Caspase-6. mRNA was prepared from the livers of naive mice (N), mice after syngeneic BMT at day 7 (S7) or day 35 (S35), and mice after allogeneic BMT at day 7 (A7) or day 35 (A35). The data represent the average of microarray and RPA, and error bars indicate standard deviation. The x-axis of microarray represents PM-MM differences of each gene, while the x-axis of RPA represents the radioactivity of each gene relative to housekeeping gene L32. Statistically significant correlation of each gene was verified from the comparison of expression level between microarray and RPA using the linear regression analysis (P < .01).
