Immune Checkpoint Inhibitors and Immunomodulators for Cancer Immunotherapy: Insights Into Resistance and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
The schematic diagram illustrates the roles of novel immune checkpoints, immunomodulatory factors, cell death and multimodal technologies in cancer immunotherapy. Abstract Cancer immunotherapy has redefined cancer treatment. However, the molecular and cellular basis of immune evasion and therapeutic resistance remains incompletely understood.

Cannabinoid-Inspired Inhibitors of the SARS-CoV-2 Coronavirus 2′-O-Methyltransferase (2′-O-MTase) Non-Structural Protein (Nsp10–16)

open access: yesMolecules
The design and synthesis of antiviral compounds were guided by computationally predicted data against highly conserved non-structural proteins (Nsps) of the SARS-CoV-2 coronavirus.

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

open access: yes, 2007
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...

Cancer‐Associated Fibroblasts Promote Tumor Immunosuppression in Hepatocellular Carcinoma via the NNMT‐ANGPTL4 Axis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Background & Aims: Cancer‐associated fibroblasts (CAFs) drive immunosuppression in hepatocellular carcinoma (HCC). However, their metabolic regulation remains poorly defined. We investigated the role of nicotinamide N‐methyltransferase (NNMT) in CAFs. Approach & Results: High NNMT expression in CAF tissues was confirmed by western blotting and

NSUN5 Attenuates Renal Injury and Ferroptosis in Hyperuricaemic Nephropathy Through YBX2‐Dependent Stabilisation of SCD1 m5C Methylation

open access: yesAdvanced Science, EarlyView.
NSUN5 is downregulated in hyperuricaemic nephropathy. Overexpression of NSUN5 enhances the stability of SCD1 mRNA through the m5C reader YBX2, ultimately inhibiting ferroptosis in renal tubular epithelial cells. Additionally, this axis suppresses the NF‐κB signaling pathway to alleviate inflammation and upregulates ABCG2 to promote uric acid excretion,

Promoter Hypermethylation‐Induced Silencing of FXYD1 Drives Breast Cancer Metastasis via DDX5‐Mediated Wnt/β‐Catenin Pathway Activation

open access: yesAdvanced Science, EarlyView.
This study identifies FXYD1 as an epigenetically silenced tumor suppressor in breast cancer. DNA methylation turns off the gene FXYD1 in breast cancer, and low levels predict worse outcomes. Restoring FXYD1 limits breast cancer cells proliferation and metastasis. In the nucleus, FXYD1 recruits the E3 ligase MAEA to K63‐ubiquitinate DDX5 for proteasomal

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

open access: yesAdvanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

open access: yesAdvanced Science, EarlyView.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

open access: yesAdvanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...
