Abstract:
The zinc finger CCCH-type containing 11A (ZC3H11A) gene encodes a well-conserved zinc finger protein that may function in mRNA export as it has been shown to associate with the transcription export (TREX) complex in proteomic screens. Here, we report that ZC3H11A is a stress-induced nuclear protein with RNA-binding capacity that localizes to nuclear splicing speckles. During an adenovirus infection, the ZC3H11A protein and splicing factor SRSF2 relocalize to nuclear regions where viral DNA replication and transcription take place. Knockout (KO) of ZC3H11A in HeLa cells demonstrated that severa

Abstract:
AbstractN6-methyladenosine (m6A) is the most prevalent modification of mammalian cellular RNAs. m6A methylation is linked to epigenetic regulation of several aspects of gene expression, including RNA stability, splicing, nuclear export, RNA folding, and translational activity. m6A modification is reversibly catalyzed by methyltransferases (m6A writers) and demethylases (m6A erasers), and the dynamics of m6A-modified RNA are regulated by m6A-binding proteins (m6A readers). Recently, several studies have shown that m6A methylation sites have been identified in hepatitis B virus (HBV) transcripts

Abstract:
Human immunodeficiency viruses type 1 and 2 (HIV-1 and HIV-2) are the causative agents of the acquired immunodeficiency syndrome (AIDS). While both viruses share a similar structural and genomic organization, a difference in replication dynamics and the clinical course of infection is evident between the two. Patients dually infected were shown to have lower viral loads and generally a slower rate of progression to AIDS than those who are mono-infected. While the roles of the unique accessory proteins have been studied in detail for HIV-1, those of HIV-2, including viral protein X (Vpx), remai

Abstract:
ABSTRACTReplication of the integrated HIV-1 genome is tightly regulated by a series of cellular factors. In previous work we showed that transactivation of the HIV-1 promoter is regulated by the cellular splicing factor SRSF1. Here we report that SRSF1 can downregulate the replication of B, C, and D subtype viruses by >200-fold in a cell culture system. We show that viral transcription and splicing are inhibited by SRSF1 expression. Furthermore, SRSF1 deletion mutants containing the protein RNA-binding domains but not the arginine serine-rich activator domain can downregulate viral replicat

To elucidate further the barriers against HIV-1 replication in mouse cells, we analyzed the replication of the virus in lymphocytes from human CD4/CXCR4 transgenic mice.

Abstract:
ABSTRACT Splicing and posttranscriptional processing of eukaryotic gene transcripts are linked to their nuclear export and cytoplasmic expression. Unspliced pre-mRNAs and intronless transcripts are thus inherently poorly expressed. Nevertheless, human and animal viruses encode essential genes as single open reading frames or in the intervening sequences of other genes. Many retroviruses have evolved mechanisms to facilitate nuclear export of their unspliced mRNAs. For example, the human immunodeficiency virus RNA-binding protein Rev associates with the soluble cellular export receptor CRM 1 (e

ABSTRACTCell-to-cell transmission is an efficient mechanism to disseminate human immunodeficiency virus type 1 (HIV-1) and human T cell lymphotropic virus type 1 (HTLV-1). However, it has been challenging to quantify the level of cell-to-cell transmission because the virus-producing cells cannot be easily distinguished from infected target cells. We have previously described replication-dependent vectors that can quantify infection events in cocultured cells. These vectors contain an antisense-oriented promoter and reporter gene interrupted by a sense-oriented intron from the human gamma-globi

My research focuses on structures of the genomes of single-stranded RNA viruses. The first project is concerned with the sequence and secondary structure of HIV-1 RNA. Based on the secondary structure that Watts et al. determined, I performed a series of analysis and the results suggested that the abundance of Adenosines at the wobble position of the codons leads to an unusual structure with numerous unpaired nucleotides. The findings indicated how the virus balances evolutionary pressures on the genomic RNA secondary structure against pressures on the sequence of the viral proteins. The secon

Abstract:
HIV is a member of the lentivirus subfamily of retroviruses. Two distinct groups of viruses are pathogenic in humans: HIV-1 and HIV-2. Both are transmitted sexually and known to cause immunodeficiency disease. HIV enters the cell through use of the CD4 receptor and chemokine co-receptors, primarily CCR5 and CXCR4. The viral genome is transcribed from RNA to DNA by reverse transcriptase and integrated into the host genome by integrase. The HIV genome encodes 15 proteins, comprising three categories: structural, regulatory, and accessory. After budding from the host cell, the virus matures into

It is obvious that the process of developing cancer—oncogenesis—is a multistep process. We know that smoking, obesity, and a family history are strong independent predictors of developing malignancy; yet, in clinics, we often see that some heavy smokers live into their nineties and that some people with close relatives affected by cancer spend many years worrying about a disease that, in the end, they never contract.

Abstract:
‘Kill or be killed’ shows how viruses survive—they must reproduce before the host either dies or its immune system recognizes and eliminates them. The transmission routes of viruses such as flu, measles, common cold, herpes simplex virus, HIV, Epstein–Barr, and hepatitis B are discussed. How do we fight viruses? All living organisms have defences against invading viruses. Vertebrates, and possibly some invertebrates, are immune to re-infection by the same virus. Another protective mechanism, used by plants, but also by insects and other animal species, is gene silencing by RNA interference. The human immune response is explained, discussing the role of lymphocytes and immunopathology, where the immune response may actually harm the body.

Abstract:
Human diseases caused by single-stranded, positive-sense RNA viruses, are among the deadliest of the 21st Century. In particular, there are two notable standouts: human immunodeficiency virus (HIV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Detection of these disease-causing viral transcripts, by next-generation RNA sequencing (RNA-Seq), represents the most immediate opportunity for advances in diagnostic, therapeutic, and preventive applicability in infectious diseases (e.g., AIDS and COVID-19). Moreover, RNA-Seq technologies add significant value to public health studies by first, providing real-time surveillance of known viral strains, and second, by the augmentation of epidemiological databases, construction of annotations and classifications of novel sequence variants. This chapter intends to recapitulate the current knowledge of HIV and SARS-CoV-2 transcriptome architecture, pathogenicity, and some features of the host immune response. Additionally, it provides an overview of recent advances in diagnostic sequencing methodologies and discusses the future challenges and prospects on the utilization of RNA-Seq technologies.
