Open AccessRing finger protein 39 genetic variants associate with HIV-1 plasma viral loads and its replication in cell culture
The human immunodeficiency virus (HIV-1) exploits host proteins to complete its life cycle. Genome-wide siRNA approaches suggested that host proteins affect HIV-1 replication. However, the results barely overl...

Open AccessSorting nexin 24 genetic variation associates with coronary artery aneurysm severity in Kawasaki disease patients
The sorting nexin (SNX) family is involved in endocytosis and protein trafficking and plays multiple roles in various diseases. The role of SNX proteins in Kawasaki disease (KD) is not known. We attempted to t...

Open AccessTombusvirus P19 RNA silencing suppressor (RSS) activity in mammalian cells correlates with charged amino acids that contribute to direct RNA-binding
Tombusvirus P19 is a protein encoded by tomato bushy stunt virus and related tombusviruses. Earlier studies have demonstrated that P19 is an RNA silencing suppressor (RSS) in plant cells. However, it has not b...

Open AccessRNAi in the regulation of mammalian viral infections
Although RNA interference (RNAi) is known to play an important part in defense against viruses of invertebrates, its contribution to mammalian anti-viral defense has been a matter of dispute. This is surprisin...

Open AccessUnstabilized DNA breaks in HTLV-1 Tax expressing cells correlate with functional targeting of Ku80, not PKcs, XRCC4, or H2AX
Expression of the human T-cell leukemia virus type 1 (HTLV-1) Tax oncoprotein rapidily induces a significant increase of micronuclei (MN) and unstabilized DNA breaks in cells. Unstabilized DNA breaks can have ...

Open AccessReplication competent HIV-1 viruses that express intragenomic microRNA reveal discrete RNA-interference mechanisms that affect viral replication
It remains unclear whether retroviruses can encode and express an intragenomic microRNA (miRNA). Some have suggested that processing by the Drosha and Dicer enzymes might preclude the viability of a replicatin...

Open AccessA proteomic study of TAR-RNA binding protein (TRBP)-associated factors
The human TAR RNA-binding protein, TRBP, was first identified and cloned based on its high affinity binding to the small hairpin trans-activation responsive (TAR) RNA of HIV-1. TRBP has more recently been foun...

A Method to Study the Role of DDX3 RNA Helicase in HIV-1
Viral replication requires the use of host cell proteins and enzymes. Many viruses utilize viral helicases at various stages of their life cycle; these viruses have evolved to encode directly helicase or helic...

The retroviral oncoprotein Tax targets the coiled-coil centrosomal protein TAX1BP2 to induce centrosome overduplication
Emerging evidence suggests that supernumerary centrosomes drive genome instability and oncogenesis1,2,3. Human T-cell leukaemia virus type I (HTLV-I) is etiologically associated with adult T-cell leukaemia (ATL)4

MicroRNAs in Human Immunodeficiency Virus-1 Infection
Initially reported for Caenorhabditis elegans, microRNA (miRNA) has been shown to regulate gene expression in plants, flies, and mammals (1,2). Recently, findings of miRNA have been extended to viruses (3,4). Her...

siRNA, miRNA and HIV: promises and challenges
Small interfering RNA (siRNA) and microRNA (miRNA) are small RNAs of 18-25 nucleotides (nt) in length that play important roles in regulating gene expression. They are incorporated into an RNA-induced silencin...

A non-proteolytic role for ubiquitin in Tat-mediated transactivation of the HIV-1 promoter
The human immunodeficiency virus type 1 (HIV-1) encodes a potent transactivator, Tat, which functions through binding to a short leader RNA, called transactivation responsive element (TAR). Recent studies sugg...
