Analysis of Epstein-Barr virus-regulated host gene expression changes through primary B-cell outgrowth reveals delayed kinetics of latent membrane protein 1-mediated NF-κB activation.
(Journal of virology, 2012-10)Epstein-Barr virus (EBV) is an oncogenic human herpesvirus that dramatically reorganizes host gene expression to immortalize primary B cells. In this study, we analyzed EBV-regulated host gene expression changes following ... -
Assessing the utility of thermodynamic features for microRNA target prediction under relaxed seed and no conservation requirements.
(PLoS One, 2011)BACKGROUND: Many computational microRNA target prediction tools are focused on several key features, including complementarity to 5'seed of miRNAs and evolutionary conservation. While these features allow for successful ... -
Complete genome sequencing and analysis of six enterovirus 71 strains with different clinical phenotypes.
(Virol J, 2013-04-11)BACKGROUND: Hand, foot and mouth diseases (HFMD) caused by enterovirus 71(EV71) presents a broad spectrum of clinical manifestations ranging from mild febrile disease to fatal neurolocal disease. However, the mechanism of ... -
Cross-platform analysis of HIV-1 RNA data generated by a multicenter assay validation study with wide geographic representation.
(J Clin Microbiol, 2012-08)HIV-1 RNA quantitation continues to be extremely important for monitoring patients infected with HIV-1, and a number of assays have been utilized for this purpose. Differences in assay performance with respect to log(10) ... -
Differential prevalence and geographic distribution of hepatitis C virus genotypes in acute and chronic hepatitis C patients in Vietnam.
(PloS one, 2019-01)BACKGROUND:The highest burden of disease from hepatitis C virus (HCV) is found in Southeast Asia, but our understanding of the epidemiology of infection in many heavily burdened countries is still limited. In particular, ... -
Durability of antiretroviral therapy and predictors of virologic failure among perinatally HIV-infected children in Tanzania: a four-year follow-up.
(BMC Infect Dis, 2014-11-07)BACKGROUND: In Tanzania, HIV-1 RNA testing is rarely available and not standard of care. Determining virologic failure is challenging and resistance mutations accumulate, thereby compromising second-line therapy. We evaluated ... -
Effective treatment of SIVcpz-induced immunodeficiency in a captive western chimpanzee.
(Retrovirology, 2017-06-02)Simian immunodeficiency virus of chimpanzees (SIVcpz), the progenitor of human immunodeficiency virus type 1 (HIV-1), is associated with increased mortality and AIDS-like immunopathology in wild-living chimpanzees ... -
Elucidation of hepatitis C virus transmission and early diversification by single genome sequencing.
(PLoS Pathog, 2012)A precise molecular identification of transmitted hepatitis C virus (HCV) genomes could illuminate key aspects of transmission biology, immunopathogenesis and natural history. We used single genome sequencing of 2,922 half ... -
Epstein-Barr virus induces global changes in cellular mRNA isoform usage that are important for the maintenance of latency.
(Journal of virology, 2013-11)Oncogenic viruses promote cell proliferation through the dramatic reorganization of host transcriptomes. In addition to regulating mRNA abundance, changes in mRNA isoform usage can have a profound impact on the protein output ... -
Functional coupling between TRPV4 channel and TMEM16F modulates human trophoblast fusion.
(eLife, 2022-06-07)TMEM16F, a Ca2+-activated phospholipid scramblase (CaPLSase), is critical for placental trophoblast syncytialization, HIV infection, and SARS-CoV2-mediated syncytialization, however, how TMEM16F is activated during cell ... -
Impact of simian immunodeficiency virus infection on chimpanzee population dynamics.
(PLoS Pathog, 2010-09-23)Like human immunodeficiency virus type 1 (HIV-1), simian immunodeficiency virus of chimpanzees (SIVcpz) can cause CD4+ T cell loss and premature death. Here, we used molecular surveillance tools and mathematical modeling ... -
Initiation of antiretroviral therapy in HIV-infected adults with skin complaints in northern Tanzania.
(Int J Dermatol, 2015-01)Abnormal skin findings are identified in over 90% of human immunodeficiency virus (HIV)-infected persons globally. A prospective cohort study of HIV-infected patients with skin complaints commencing antiretroviral therapy ... -
Lopinavir/ritonavir monotherapy after virologic failure of first-line antiretroviral therapy in resource-limited settings.
(AIDS, 2012-07-17)OBJECTIVE: To evaluate virologic response rates of lopinavir/ritonavir (LPV/r) monotherapy as second-line antiretroviral treatment (ART) among adults in resource-limited settings (RLSs). DESIGN: An open-label pilot study ... -
Lopinavir/Ritonavir Monotherapy as Second-line Antiretroviral Treatment in Resource-Limited Settings: Week 104 Analysis of AIDS Clinical Trials Group (ACTG) A5230.
(Clin Infect Dis, 2015-05-15)BACKGROUND: The AIDS Clinical Trials Group (ACTG) A5230 study evaluated lopinavir/ritonavir (LPV/r) monotherapy following virologic failure (VF) on first-line human immunodeficiency virus (HIV) regimens in Africa and Asia. ... -
MicroRNA antagonism of the picornaviral life cycle: alternative mechanisms of interference.
(PLoS Pathog, 2010-03-19)In addition to modulating the function and stability of cellular mRNAs, microRNAs can profoundly affect the life cycles of viruses bearing sequence complementary targets, a finding recently exploited to ameliorate toxicities ... -
Origin and evolution of HIV-1 in breast milk determined by single-genome amplification and sequencing.
(J Virol, 2011-03)HIV transmission via breastfeeding accounts for a considerable proportion of infant HIV acquisition. However, the origin and evolution of the virus population in breast milk, the likely reservoir of transmitted virus variants, ... -
Predicting virologic failure among HIV-1-infected children receiving antiretroviral therapy in Tanzania: a cross-sectional study.
(J Acquir Immune Defic Syndr, 2010-08)BACKGROUND: Many HIV care and treatment programs in resource-limited settings rely on clinical and immunologic monitoring of antiretroviral therapy (ART), but accuracy of this strategy to detect virologic failure (VF) among ... -
Safety, tolerability, and mechanisms of antiretroviral activity of pegylated interferon Alfa-2a in HIV-1-monoinfected participants: a phase II clinical trial.
