HE activity of xanthine dehydrogenase (XDH) in Drosophila melanogaster is affected by mutations at three loci: ma4 at locus 64ion the X chromosome, ry at locus 52 ion the third chromosome, and lxd at locus 33 ? on the third chromosome. See GLASSMAN (1965) for a discussion of these loci. The ma4 and the ry mutants are deficient in XDH while lzd flies have 20(More)
Hepatitis B virus (HBV) is a driver of hepatocellular carcinoma, and two viral products, X and large surface antigen (LHBS), are viral oncoproteins. During chronic viral infection, immune-escape mutants on the preS2 region of LHBS (preS2-LHBS) are gain-of-function mutations that are linked to preneoplastic ground glass hepatocytes (GGHs) and early disease(More)
