dsRNA-mediated reduction of virus in honey bees.

, 2013
(A) Schematic of experiment. Honey bees were inoculated with SINV-GFP or co-injected with (B) nucleic acid treatments including: virus-specific dsRNA (SINV dsRNA); non-specific dsRNA corresponding to Drosophila C virus (DCV) sequence (DCV dsRNA); poly(I ...

Characterization of the VPg-dsRNA linkage of infectious pancreatic necrosis virus

Journal of General Virology, 1991
By the use of strong denaturing agents, a genome-linked protein (VPg)-RNA complex was purified from infectious pancreatic necrosis virus. Ribonuclease treatment of 125I-labelled VPg-RNA released a 90K polypeptide identical to the minor structural polypeptide VP1 (the putative RNA polymerase), as determined by peptide mapping.

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

Diversity of Citrus Tristeza Virus Isolates Indicated by dsRNA Analysis

Intervirology, 1987
One major dsRNA of molecular weight (MW) 13.3 X 10(6) and two others (MW 1.9 X 10(6) and 0.8 X 10(6] were routinely detected by polyacrylamide gel electrophoresis in extracts from sweet orange (Citrus sinensis) or citron (Citrus medica) infected with each of 66 isolates of citrus tristeza virus (CTV).

The Novel Viral Non‐Coding RNA LMP2A‐IT1 Promotes the Lytic Replication of EBV

Advanced Science, EarlyView.
Decades after its discovery, EBV's genome still harbours unannotated “dark matter”. LMP2A‐IT1, a novel EBV‐encoded transcript identified in this work, is strongly upregulated during lytic replication and promotes BZLF1 expression, likely through activation of inflammatory responses, thereby enhancing viral propagation in a self‐reinforcing positive ...

SUMOylated DDX3 Promotes HBV Replication and Tumor Growth of Hepatocellular Carcinoma via TRIM28‐DDX3‐KLF4α Signaling Axis

Advanced Science, EarlyView.
TRIM28 binds to DDX3 protein to catalyze the SUMOylation of DDX3 (S‐DDX3), thus the S‐DDX3 involves in aberrant alternative splicing of KLF4 mRNA, and the splicing variant KLF4α‐mediated cell cycle and signal transduction, weakens tumor suppressor function of DDX3 protein, which promotes progression of HBV‐HCC.

Those magnificent molecular machines: logistics in dsRNA virus transcription [PDF]

The EMBO Reports, 2002
Double‐stranded (ds) RNA viruses face two major challenges when infecting a cell: the cellular replicative machinery does not operate on dsRNA genomes, and dsRNA provokes a strong apoptotic response. To overcome these problems, dsRNA viruses conceal their genomes from the host cell in an enclosed icosahedral viral core, but then need to carry with them

Synthetic Particulate Subunit Vaccines Co‐Delivering Multiple Antigens Induce Protective Immunity Against Melioidosis

Advanced NanoBiomed Research, EarlyView.
Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...

Reduction in Acute Bee Paralysis Virus Infection and Mortality in Honey Bees (Apis mellifera) by RNA Interference Technology

Insects
In Argentina, various studies have reported the detection of multiple viruses in honey-producing and queen-rearing apiaries, with Aparavirus apisacutum, the causal agent of acute bee paralysis (ABP), demonstrating a particularly high prevalence.
