Effect of actinomycin D on simian rotavirus (SA11) replication in cell culture

Brazilian Journal of Medical and Biological Research, 2002
Rotaviruses are the major cause of viral diarrhea in humans and animals. Actinomycin D (Act D) is an antibiotic that intercalates DNA and therefore inhibits DNA-dependent transcription.

Targeting Dnmt3a/m5C/RelA Axis Attenuates Microglia Inflammatory Response and Improves Postoperative Recovery in Chronic Compressive Cervical Spinal Cord Injury

Advanced Science, EarlyView.
A pro‐inflammatory microglial subset persists after decompression in chronic compressive cervical spinal cord injury and shows enhanced Dnmt3a‐driven m5C signaling. By stabilizing RelA mRNA, this axis sustains NF‐κB activation and postoperative neuroinflammation.

ZNF33B Promotes Japanese Encephalitis Virus Infection by Regulating the Stability of M6A‐Modified Trim25 to Control the Autophagy Process

Advanced Science, EarlyView.
Upon JEV infection, ZNF33B recruits METTL14 to stabilize the METTL3‐METTL14 m6A methyltransferase complex, leading to increased m6A modification of host transcripts, including Trim25 mRNA. ZNF33B selectively binds m6A‐modified sites on Trim25 mRNA and accelerates its decay, resulting in reduced TRIM25 protein abundance.

RNA‐Binding Protein RBM25 Targets the mRNA Stability of GTPase Rab22a to Restrict Viral Entry and Infection

Advanced Science, EarlyView.
This study identifies RNA‐binding protein RBM25 as a broad‐spectrum antiviral factor acting independently of type I interferon. It blocks viral entry by suppressing GTPase Rab22a via the RC3H1‐mediated destabilization of Rab22a mRNA. Viral downregulation of RBM25 enhances GTPase Rab22a expression and viral entry, revealing an unreported post ...

RBM12 Maintains Glioma Stem Cells by Activating Amino Acid‐Dependent mTORC1 Signaling via SLC7A5 mRNA Stabilization

Advanced Science, EarlyView.
This study shows that in glioma stem cells (GSCs), RBM12 recruits ALKBH5 to remove m6A from SLC7A5 transcripts, thereby enhancing mRNA stability, which elevates large neutral amino acid (LNAA) levels and activates mTORC1, promoting GSC proliferation, self‐renewal, and tumor growth.

Therapeutic Silencing of Tmprss6 Reduces Iron‐Induced Inflammation and Prolongs Survival in MDS Mice

American Journal of Hematology, EarlyView.
ABSTRACT Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders characterized by ineffective hematopoiesis, cytopenias, and an increased risk of progression to acute myeloid leukemia (AML). Despite advances in supportive and targeted therapies, disease‐modifying interventions remain limited.

Effect of Actinomycin-D on Calcium Homeostasis

Experimental Biology and Medicine, 1965
SummaryActinomycin-D produces hypocalcemia in rats 10 to 15 hours after administration. This effect can be produced in the absence of kidneys, adrenals and thyroid glands. Possible mechanisms of action are discussed.

Effect of Actinomycin D on Morphine Tolerance.

Experimental Biology and Medicine, 1965
SummaryThe inhibitor of protein synthesis, actinomycin D, is capable of decreasing the rate of development of morphine tolerance in mice and rats. This effect may be the result of the suppression of the synthesis of new RNA and consequently of proteins or peptides which counteract the effects of morphine.
