Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

Progesterone Administration Modulates Cortical TLR4/NF-κB Signaling Pathway after Subarachnoid Hemorrhage in Male Rats

Mediators of Inflammation, 2011
Our previous study concerning brain trauma has shown that progesterone could regulate toll-like receptor 4 (TLR4) and nuclear factor-kappa B (NF-κB) signaling pathway in the brain, which also has been proved to play important roles in early brain injury (

PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

Advanced Science, EarlyView.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.

Enhanced Glycolysis‐Driven Histone H3K18 Lactylation Regulates Epileptogenesis by Modulating the E3 Ubiquitin Ligase COP1

Advanced Science, EarlyView.
Neuronal PKM2‐driven glycolysis generates excess lactate that triggers histone H3K18 lactylation (H3K18la), establishing a pathogenic metabolic‐epigenetic axis in epilepsy. Elevated H3K18la enriches the Cop1 promoter, transcriptionally upregulating the E3 ubiquitin ligase COP1, which subsequently drives proteasomal degradation of GABAARβ2 and impairs ...

Aged garlic attenuates neuroinflammation via modulating the NF-κB pathway: Insights from multi-omics analyses

Food & Nutrition Research
Background: Neuroinflammation is a key pathological feature in many neurodegenerative diseases, and the nuclear factor kappa-B (NF-κB) signaling pathway is a central mediator of this response.

A Radioresistant‐Tumor‐Targeted Nanoparticle for X‐Ray‐Controlled Nitric Oxide Release to Potentiate Radiotherapy

Advanced Science, EarlyView.
The PBTN targets GRP78 and, upon X‐ray irradiation, generates ONOO− to induce immunogenic cell death, thereby activating CD8+ T cells and establishing a systemic antitumor immune response. ABSTRACT Nitric oxide (NO) treated radioresistant tumors by relieving hypoxia and blocking DNA repair, but its nonselective toxicity has precluded therapeutic use ...

Decoding IGLL5 Mutation‐Mediated BCR Signaling: A Novel Mechanism of CD8+ T Cell Exhaustion and Ocular MALT Lymphoma Progression

Advanced Science, EarlyView.
OAML harbors recurrent IGLL5 mutations that reinforce CD79A/CD79B‐associated BCR signaling. Mechanistic analysis of the S47G and A54G variants reveals induction of CXCL10/CXCL11, enhanced CD8+ T‐cell recruitment, and exhaustion‐associated dysfunction, supporting an immune‐tolerant niche.

CHIP/STUB1 suppresses the transcription and latent reactivation of HIV-1 via the TRAF6-NF-κB-HIV-LTR axis.

PLoS Pathogens
HIV-1 replication, transcription and latency are correlated with the activation of NF-κB signaling. C-terminus of Hsc70-interacting protein (CHIP or STUB1), a cellular E3 ligase, has been reported to inhibit Tat-mediated HIV-1 LTR promoter activity by ...

p100 Deficiency is insufficient for full activation of the alternative NF-κB pathway: TNF cooperates with p52-RelB in target gene transcription.

PLoS ONE, 2012
BackgroundConstitutive activation of the alternative NF-κB pathway leads to marginal zone B cell expansion and disorganized spleen microarchitecture. Furthermore, uncontrolled alternative NF-κB signaling may result in the development and progression of ...
