RNA‐Binding Proteins Shape Mammalian Retroelement RNA Fate: Lessons From HIV‐1, LINE‐1, and Related Reverse‐Transcribing Elements

Animal Research and One Health, EarlyView.
RNA‐binding proteins (RBPs) and RNA‐associated factors shape retroelement RNA fate by regulating RNA processing, translation, RNP assembly and remodeling, reverse transcription, nuclear trafficking, chromatin engagement, and RNA surveillance. These pathways balance productive retroviral replication or retrotransposon insertion with RNA decay ...

Retrovirus Restriction Factors [PDF]

Molecular Cell, 2004
A number of cellular genes have recently been identified that actively inhibit retrovirus replication and so protect cells from infection. The genes target many distinct steps in the viral life cycle: entry, viral DNA synthesis, intracellular movement of viral nucleic acids, and viral gene expression.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

Arthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Feasibility Assessment of a Single‐pH Connected Polishing Train for Monoclonal Antibody Purification Using Mildly Acidic Protein A Elution and an Acidic‐Window Anion Exchange Membrane

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Monoclonal antibody downstream processing often requires multiple pH adjustments between Protein A capture and polishing steps. These adjustments increase process complexity and make direct unit‐operation connection more difficult. We evaluated a connected post‐capture polishing block operated at approximately pH 5.0 using mild‐pH Protein A ...

Synergistic effects of HDAC inhibitor tucidinostat and ENT inhibitor dipyridamole in T-cell malignancies

Scientific Reports
Achieving both selectivity and cytotoxicity against cancer cells remains a major challenge in cancer therapy. Histone deacetylase (HDAC) inhibitors, such as tucidinostat, suppress tumor growth by epigenetically regulating tumor suppressor gene expression

DNA concentration in harvest affects retrovirus clearance capabilities of protein A chromatography

Biotechnology Progress, EarlyView.
Abstract Protein A chromatography is a key unit operation in biopharmaceutical purification, widely used to capture monoclonal antibodies (mAbs) from harvest cell culture fluid (HCCF). In addition to its primary function, protein A chromatography is also frequently tested for its ability to remove viruses. Although protein A specifically binds mAbs and

Retrovirus silencer blocking by the cHS4 insulator is CTCF independent

, 2003
Silencing of retrovirus vectors poses a significant obstacle to genetic manipulation of stem cells and their use in gene therapy. We describe a mammalian silencer blocking assay using insulator elements positioned between retrovirus silencer elements and
