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.

Glutathione‐Responsive Acyl‐Modifications for Targeted RNA Decaging and Prolonged Protein Synthesis

Angewandte Chemie, EarlyView.
The self‐immolation of disulfide‐based mRNA modifications in response to endogenous glutathione (GSH) promotes a gradual release of translatable mRNA within the cell, leading to improved nuclease resistance, tunable release properties, and a significant increase (up to 600%) of target protein production over time. This strategy offers an exciting proof

N6-methyladenosine demethylase FTO promotes growth and metastasis of gastric cancer via m6A modification of caveolin-1 and metabolic regulation of mitochondrial dynamics

Cell Death and Disease, 2022
Gastric cancer (GC) is the fifth most common tumor and the third most deadly cancer worldwide. N6-methyladenosine (m6A) modification has been reported to play a regulatory role in human cancers.

The RNA moiety of chick embryo 5-methylcytosine- DNA glycosylase targets DNA demethylation [PDF]

Nucleic Acids Research, 1997
We have previously shown that DNA demethylation by chick embryo 5-methylcytosine (5-MeC)-DNA glycosylase needs both protein and RNA. RNA from enzyme purified by SDS-PAGE was isolated and cloned. The clones have an insert ranging from 240 to 670 bp and contained on average one CpG per 14 bases.

TET1 Inhibition Promotes Therapeutic Sensitivity in TP53‐Mutant GBM by Influencing Genome Fragility and Altering TAMs Biology

Advanced Science, EarlyView.
In TP53mut GBM cells, reduced P53 function is associated with increased TET1 expression. Genetic or pharmacological inhibition of TET1 correlates with genome fragility, including DNA damage, cellular senescence, telomere shortening, and reactive oxygen species accumulation, which may contribute to increased efficacy of antitumor therapy.

Proteome‐Wide Target Identification Using Reactive Metallo‐Scaffolds (r‐mS): A Platform for Metallodrug Discovery

Angewandte Chemie, EarlyView.
Re‐envisioning the Ligandable Proteome: Reactive Metallo‐Scaffolds (r‐mS) combine non‐covalent protein engagement by a metallo‐scaffold with covalent cysteine capture through a tethered chloroacetamide warhead. Chemoproteomic profiling reveals unique enzyme engagement including ligases, kinases and methyltransferases, highlighting opportunities for ...

YTH Domain: A Family of N6-methyladenosine (m6A) Readers

Genomics, Proteomics & Bioinformatics, 2018
Like protein and DNA, different types of RNA molecules undergo various modifications. Accumulating evidence suggests that these RNA modifications serve as sophisticated codes to mediate RNA behaviors and many important biological functions.

ALKBH5 controls the meiosis-coupled mRNA clearance in oocytes by removing the N  6 -methyladenosine methylation

Nature Communications, 2023
N 6 -methyladenosine (m6A) maintains maternal RNA stability in oocytes. One regulator of m6A, ALKBH5, reverses m6A deposition and is essential in RNA metabolism. However, the specific role of ALKBH5 in oocyte maturation remains elusive.

Targeting mitochondrial RNAs enhances the efficacy of the DNA-demethylating agents

Scientific Reports
Hypomethylating agents (HMAs) such as azacytidine and decitabine are FDA-approved chemotherapy drugs for hematologic malignancy. By inhibiting DNA methyltransferases, HMAs reactivate tumor suppressor genes (TSGs) and endogenous double-stranded RNAs (dsRNAs) that limit tumor growth and trigger apoptosis via viral mimicry.
