Expression of KSHV and human genes in KS lesions. A Sections from KS skin tumor sample S9T were stained with H&E for pathology or stained by immunohistochemistry for KSHV LANA protein or human endothelial marker CD31. Scale bars = 100 µm. B The same tissue sample was analyzed by RNA in situ hybridization with probes to the KSHV RNAs ORF75 and vIL6. Scale bars = 100 µm for left and 50 µm for right image. C KS GI tumor sample G2T was stained with H&E or for KSHV LANA protein. Scale bars = 100 µm for left two images and 20 µm for image on right. D KS GI tumor sample G2T was analyzed for expression of KSHV ORF75 and vIL6 RNAs. Scale bar = 100 µm for left image and 50 µm for right image
