Influence Of Env And Long Terminal Repeat Sequences On The Tissue Tropism Of Avian Leukosis Viruses, David Brown, Harriet Robinson
David C. Brown
Adsorption and penetration of retroviruses into eucaryotic cells is mediated by retroviral envelope glycoproteins interacting with host receptors. Recombinant avian leukosis viruses (ALVs) differing only in envelope determinants that interact with host receptors for subgroup A or E ALVs have been found to have unexpectedly distinctive patterns of tissue-specific replication. Recombinants of both subgroups were highly expressed in bursal lymphocytes as well as in cultured chicken embryo fibroblasts. In contrast, the subgroup A but not subgroup E host range allowed high levels of expression in skeletal muscle, while subgroup E but not subgroup A envelope glycoproteins permitted efficient replication in …

Alcohol And Hcv: Implications For Liver Cancer, Gyongyi Szabo, Banishree Saha, Terence Bukong

Liver cancers are one of the deadliest known malignancies which are increasingly becoming a major public health problem in both developed and developing countries. Overwhelming evidence suggests a strong role of infection with hepatitis B and C virus (HBV and HCV), alcohol abuse, as well as metabolic diseases such as obesity and diabetes either individually or synergistically to cause or exacerbate the development of liver cancers. Although numerous etiologic mechanisms for liver cancer development have been advanced and well characterized, the lack of definite curative treatments means that gaps in knowledge still exist in identifying key molecular mechanisms and pathways …
