Mig and IP-10 mRNA expression in EBV-associated lymphoproliferative diseases. Total cellular RNA, extracted from paraffin-embedded tissues diagnosed with either LYG, nasal T/NK-cell lymphoma, lymphoid hyperplasia, malignant B-cell lymphoma, or Burkitt's lymphoma, was subjected to semiquantitative RT-PCR. After normalization to a standard RNA preparation and to G3PDH, the results of Phosphorimage analysis are shown as absolute numbers of normalized arbitrary units (pixels)/sample. (A) Mig mRNA expression; (B) IP-10 mRNA expression.
