Ferroptosis Suppression by the M6A Reader IGF2BP1 Underlies Gemcitabine Resistance in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
IGF2BP1 promotes gemcitabine resistance in pancreatic cancer by stabilizing m6A‐modified FTH1 transcripts and protecting them in stress granules, thereby suppressing ferroptosis. Pharmacological inhibition of IGF2BP1 disrupts this protective pathway, restores ferroptotic sensitivity, and enhances gemcitabine efficacy in resistant tumors.

Structure and regulation of ZCCHC4 in m6A-methylation of 28S rRNA

Nature Communications, 2019
The N6-methyladenosine (m6A) RNA modification is an evolutionarily conserved epitranscriptomic mechanism that impacts several cellular processes. Here the authors present a structure-function analysis of the ZCCHC4, 28S RNA-specific m6A methyltransferase,

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Downregulation of m6A writer complex member METTL14 in bladder urothelial carcinoma suppresses tumor aggressiveness

Molecular Oncology, 2022
N6‐methyladenosine (m6A) and its regulatory proteins have been associated with tumorigenesis in several cancer types. However, knowledge on the mechanistic network related to m6A in bladder cancer (BlCa) is rather limited, requiring further investigation

Genome-Wide Location Analyses of N6-Methyladenosine Modifications (m6A-Seq) [PDF]

, 2017
N6-methyladenosine-sequencing (m6A-seq) is a critical tool to obtain an unbiased genome-wide picture of m6A sites of modification at high resolution. It allows the study of the impact of various perturbations on m6A modification distribution and the study of m6A functions. Herein, we describe the m6A-seq protocol, which entails RNA immunoprecipitation (

Development and validation of monoclonal antibodies against N6-methyladenosine for the detection of RNA modifications.

PLoS ONE, 2019
RNA contains various chemical modifications, among which N6-methyladenosine (m6A) is the most prevalent modified nucleotide in eukaryotic mRNA. Emerging evidence suggests that m6A plays an important role in regulating a variety of cellular functions by ...

p300‐Mediated H3K18 Lactylation Drives Radiation‐Induced Pulmonary Fibrosis via VIRMA‐Dependent m6A Modification of GATA3

Advanced Science, EarlyView.
Radiation triggers glycolytic reprogramming in alveolar epithelial type II cells, causing pathological lactate accumulation. This metabolic stress drives p300‐mediated H3K18 lactylation at the VIRMA promoter, activating transcription. Elevated VIRMA enriches m6A on GATA3 mRNA, which YTHDF1 stabilizes, ultimately driving epithelial–mesenchymal ...

Dot Blot Analysis of N6-methyladenosine RNA Modification Levels

Bio-Protocol, 2017
N6-methyladenosine (m6A) is the most prevalent internal modification of eukaryotic messenger RNA (mRNA). The total amount of m6A can be detected by several methods, such as dot blot analysis using specific m6A antibodies and quantitative liquid ...
