HSP90 inhibitors stimulate DNAJB4 protein expression through a mechanism involving N6-methyladenosine. [PDF]

, 2019
Small-molecule inhibitors for the 90-kDa heat shock protein (HSP90) have been extensively exploited in preclinical studies for the therapeutic interventions of human diseases accompanied with proteotoxic stress.

Transcription Impacts the Efficiency of mRNA Translation via Co-transcriptional N6-adenosine Methylation [PDF]

, 2017
Transcription and translation are two main pillars of gene expression. Due to the different timings, spots of action, and mechanisms of regulation, these processes are mainly regarded as distinct and generally uncoupled, despite serving a common purpose.

Tumor Intrinsic METTL5 Modulates ATF4 Translation to Prevent T Cell‐Induced Ferroptosis in Ovarian Cancer

Advanced Science, EarlyView.
An integrative analysis combining in vitro genome‐wide immune screens, in vivo ICB screens, and clinical data mining identifies METTL5 as a key tumor‐intrinsic immune factor. Mechanistic studies further reveal the importance of the METTL5‐ATF4‐SLC7A11/SLC3A2‐ferroptosis axis in modulating antitumor immune responses. These findings highlight METTL5 as a

m6A mRNA demethylase FTO regulates melanoma tumorigenicity and response to anti-PD-1 blockade [PDF]

, 2019
Melanoma is one of the most deadly and therapy-resistant cancers. Here we show that N6-methyladenosine (m6A) mRNA demethylation by fat mass and obesity-associated protein (FTO) increases melanoma growth and decreases response to anti-PD-1 blockade ...

m^6A RNA methylation promotes XIST-mediated transcriptional repression [PDF]

, 2016
The long non-coding RNA X-inactive specific transcript (XIST) mediates the transcriptional silencing of genes on the X chromosome. Here we show that, in human cells, XIST is highly methylated with at least 78 N^6-methyladenosine (m^6A) residues—a ...

HPD is an m6A Methyltransferase that Protects Colorectal Cancer Cells from Ferroptotic Cell Death by m6A Methylating SLC7A11/GPX4

Advanced Science, EarlyView.
This study reveals that the tyrosine metabolic enzyme HPD functions as a previously uncharacterized, METTL3‐independent m6A methyltransferase. It promotes colorectal tumor progression by coordinately regulating the SLC7A11/GPX4 axis to suppress ferroptosis.

Structural insights into molecular mechanism for N 6-adenosine methylation by MT-A70 family methyltransferase METTL4

Nature Communications, 2022
Here the authors combine functional and structural work to show that METTL4 functions as U2 snRNA m6Am RNA methyltransferase supporting N6-methylation of 2’-O-methyladenosine in Arabidopsis.

The Tumor‐to‐Endothelial Transfer of FTO Promotes Vascular Remodeling and Metastasis in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...
