TTC22 promotes m6A-mediated WTAP expression and colon cancer metastasis in an RPL4 binding-dependent pattern
Open accessPublished version of a preprint
Abstract
Abstract WTAP, an essential component of the RNA N-6-methyladenosine (m6A) modification complex, guides METLL3-METLL14 heteroduplexes to target RNAs in the nuclear speckles of mammalian cells. Here, we show that TTC22 is widely coexpressed with WTAP and FTO in many human tissues by mining Genotype-Tissue Expression (GTEx) datasets. Our results indicate that the direct interaction of TTC22 with 60S ribosomal protein L4 (RPL4) promotes the binding of WTAP mRNA to RPL4, enhances the stability and translation efficiency of WTAP mRNA, and consequently increases the level of WTAP protein. Also, WTAP mRNA itself is an m6A target and YTHDF1 is characterized as an essential m6A binding protein in WTAP mRNA. TTC22 triggers a positive feedback loop between WTAP expression and WTAP mRNA m6A modification, leading to an increased m6A level in total RNA. The knockdown of RPL4, WTAP, or YTHDF1 expression diminishes the TTC22-induced increase in the m6A level of total RNA. Thus, TTC22 caused dramatic expression changes in genes related to metabolic pathways, ribosomal biogenesis, the RNA spliceosome, and microorganism infections. Importantly, TTC22 upregulates the expression of SNAI1 by increasing m6A level and thus promotes lung metastases of colon cancer cells in mice. In conclusion, our study showed that TTC22 upregulates WTAP and SNAI1 expression, which contributes to TTC22-induced colon cancer metastasis.

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.
