During lytic replication of human cytomegalovirus (HCMV), the most abundant viral transcripts are long non-coding RNAs (lncRNAs). Viral lncRNAs can have a variety of functions, some of which are necessary for viral production and the modulation of host processes during infection. HCMV produces four lncRNAs, Beta2.

Kaposi's sarcoma-associated herpesvirus (KSHV) DNA polymerase processivity factor, ORF59, is a lytic protein essential for viral DNA synthesis as part of the core replication complex. The multifunctional nature of ORF59 has prompted the investigation into its various functional domains. Prior studies of ORF59 have identified dimerization, DNA interaction, and polymerase interaction domains.

Kaposi's sarcoma-associated herpesvirus (KSHV) relies on many cellular proteins to complete replication and generate new virions. Paraspeckle nuclear bodies consisting of core ribonucleoproteins splicing factor proline/glutamine-rich (SFPQ), Non-POU domain-containing octamer-binding protein (NONO), and paraspeckle protein component 1 (PSPC1) along with the long non-coding RNA NEAT1, form a complex that has been speculated to play an important role in viral replication. Paraspeckle bodies are multifunctional and involved in various processes including gene expression, mRNA splicing, and anti-viral defenses.

Integrated management strategies, including novel nematicides and resilient cultivars, offer sustainable solutions to combat root-knot nematodes, crucial for safeguarding global agriculture against persistent threats. Root-knot nematodes (RKN) pose a significant threat to a diverse range of host plants, with their obligatory endoparasitic nature leading to substantial agricultural losses. RKN spend much of their lives inside or in contact by secreting plant cell wall-modifying enzymes resulting in the giant cell development for establishing host-parasite relationships.

The entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into human embryonic kidney (HEK293T) cells has been shown to be a cholesterol-rich, lipid raft-dependent process. In this study, we investigated if the presence of a cholesterol uptake receptor Niemann-pick type c1-like1 (NPC1L1) impacts SARS-CoV-2 cell entry. Initially, we utilized reporter-based pseudovirus cell entry assays and a spike (S) glycoprotein-mediated cell-to-cell fusion assay.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent of coronavirus disease 2019 (COVID-19), has posed significant challenges to global health. While much attention has been directed towards understanding the primary mechanisms of SARS-CoV-2 infection, emerging evidence suggests co-infections or superinfections with other viruses may contribute to increased morbidity and mortality, particularly in severe cases of COVID-19. Among viruses that have been reported in patients with SARS-CoV-2, seropositivity for Human cytomegalovirus (HCMV) is associated with increased COVID-19 risk and hospitalization.

G-quadruplexes (G4s) are noncanonical nucleic acid structures that play significant roles in regulating various biological processes, including replication, transcription, translation, and recombination. Recent studies have identified G4s in the genomes of several viruses, such as herpes viruses, hepatitis viruses, and human coronaviruses. These structures are implicated in regulating viral transcription, replication, and virion production, influencing viral infectivity and pathogenesis.

Kaposi's sarcoma-associated herpesvirus (KSHV) establishes life-long latent infection and is linked to several human malignancies. Latency-associated nuclear antigen (LANA) is highly expressed during latency, and is responsible for the replication and maintenance of the viral genome. The expression of LANA is regulated at transcriptional/translational levels through multiple mechanisms, including the secondary structures in the mRNA sequence.

This study showcases the creation of a biosensor strip designed for the rapid, precise, and highly sensitive electrochemical detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These biosensor strips were crafted by affixing a monoclonal antibody (mAb) specific to SARS-CoV-2 onto the surface of a commercially screen-printed carbon electrode (SPCE) modified with polyaniline-titania nanotubes (PANi-TNT). The transportable sensing device was constructed by pairing the mAb functionalized strip with a portable potentiostat wirelessly connected to either a Windows or Android device.
