METTL3 promotes pancreatic cancer proliferation and stemness by increasing stability of ID2 mRNA in a m6A-dependent manner
Abstract
In eukaryotes, N 6-methyladenosine (m6A) is the most prevalent epigenetic alteration. Methyltransferase-like 3 (METTL3) is a key player in the control of m6A, although its function in pancreatic cancer is incompletely understood. In this study, we examined the role that METTL3 plays in pancreatic cancer cell proliferation and stemness. We discovered that in pancreatic cancer cells, METTL3-mediated m6A alterations regulate ID2 as a downstream target. The stability of ID2 mRNA was decreased and m6A modification was effectively eliminated by METTL3 knockdown in pancreatic cancer cells. We also demonstrate that m6a-YTHDF2 is necessary for the METTL3-mediated stabilization of ID2 mRNA. Additionally, we show that ID2 controls the stemness molecules NANOG and SOX2 via the PI3K-AKT pathway to support pancreatic cancer growth and stemness maintenance. Our data suggest that METTL3 may post-transcriptionally upregulate ID2 expression in an m6A-YTHDF2-dependent manner to further promote the stabilization of ID2 mRNA, which may be a new target for pancreatic cancer treatment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
