RNA Modifications in Tumor Microenvironment: A New Dimension for Cancer Treatment
Tumor initiation and progression depend on a supportive and highly heterogeneous tumor microenvironment (TME). RNA modifications regulate signaling pathways and cytokine networks that shape TME dynamics, facilitating interactions between cancer cells and noncancerous stromal cells, and ultimately promoting immune evasion and tumor progression ...

The dynamic N1-methyladenosine methylome in eukaryotic messenger RNA [PDF]
Gene expression can be regulated post-transcriptionally through dynamic and reversible RNA modifications. A recent noteworthy example is N(6)-methyladenosine (m(6)A), which affects messenger RNA (mRNA) localization, stability, translation and splicing. Here we report on a new mRNA modification, N(1)-methyladenosine (m(1)A), that occurs on thousands of ...

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

The biological function of demethylase ALKBH1 and its role in human diseases
AlkB homolog 1 (ALKBH1) is a member of the AlkB family of dioxygenases that are dependent on Fe(II) and α-ketoglutarate. Mounting evidence demonstrates that ALKBH1 exhibits enzymatic activity against various substrates, including N6-methyladenosine (m6A),

The Arabidopsis TRM61/TRM6 complex is a bona fide tRNA N1-methyladenosine methyltransferase
Abstract tRNA molecules, which contain the most abundant post-transcriptional modifications, are crucial for proper gene expression and protein biosynthesis. Methylation at N1 of adenosine 58 (A58) is critical for maintaining the stability of initiator methionyl-tRNA (tRNAiMet) in bacterial, archaeal, and eukaryotic tRNAs.
