PRMT1 methylation of WTAP promotes multiple myeloma tumorigenesis by activating oxidative phosphorylation via m6A modification of NDUFS6 [m6A-Seq]

Project description:Epigenetic modifications play important roles during the pathogenesis of multiple myeloma (MM). Here, we found that protein arginine methyltransferase 1 (PRMT1) was highly expressed in MM patients and its expression level was positively correlated with MM stages. High PRMT1 expression were notably related to adverse prognosis in MM patients. We further showed that silencing PRMT1 inhibited MM proliferation and tumorigenesis in vitro and in vivo. Mechanistically, we revealed that knockdown of PRMT1 reduced the oxidative phosphorylation (OXPHOS) of MM cells through downregulation of NDUFS6. Meanwhile, we identified that WTAP, a key component of the m6A methyltransferase complex, was methylated by PRMT1 and NDUFS6 was identified as a bona fide m6A target of WTAP. Finally, we found that PRMT1 inhibitor and bortezomib combination synergistically inhibited MM progression. Collectively, our results demonstrate that PRMT1 plays a crucial role during MM tumorigenesis and suggest that PRMT1 could be a potential therapeutic target in MM.

TTC22 increasing total m6A RNA level and colon cancer metastasis via RPL4-WTAP-YTHDF1 axis

Project description:WTAP is an essential component of the RNA N-6-methyladenosine (m6A) modification complexes that guides METLL3-METLL14 heteroduplexes to target RNAs in the nucleus of mammalian cells. Through mining the genotype-tissue expression (GTEx) datasets, we initially found that TTC22 expression was highly correlated with WTAP and FTO in many normal human tissues. Our experimental results indicate that TTC22 could directly capture RNA binding protein RPL4, induce the binding between RPL4 and WTAP mRNA in the cytoplasm, which increased the m6A level, induced alterative splicing, enhanced the stability and translation efficiency of WTAP mRNA, and consequently upregulated the level of total m6A RNA. These results indicate that WTAP mRNA is a m6A target and there is a positive feedback loop between total m6A and WTAP expression. YTHDF1 was found to be an essential m6A WTAP mRNA binding protein. Downregulation of RPL4, WTAP, or YTHDF1 expression could reverse TTC22-enhanced total m6A RNA level. m6A-specific antibody immunoprecipitated RNA-sequencing (meRIP-seq) demonstrated that TTC22 caused dramatic expression changes of genes related to metabolic pathways, ribosome biogenesis, and RNA spliceosome. Furthermore, we also found that TTC22 upregulated the expression of epithelial-mesenchymal transition (EMT)-related gene SNAI1 via m6A, and promoted metastasis of colon cancer in vitro and in mice. In conclusion, our study illustrates that WTAP mRNA is a m6A target using YTHDF1 as the binding protein. TTC22 could upregulate the levels of WTAP expression and total m6A RNA through the PRL4 binding. The m6A-mediated upregulation of SNAI1 expression may contribute to TTC22-enhanced colon cancer metastasis.

WTAP-mediated m6A modification profiling in human nasopharyngeal carcinoma cell lines

Project description:N(6)-methyladenosine (m6A) plays an important role in the tumorigenesis and progression of cancers. However, the clinical significance of m6A and their regulatory mechanisms in nasopharyngeal carcinogenesis (NPC) remain largely unknown. In this study, we used the microarray analysis to study WTAP-mediated m6A modification profiles in human nasopharyngeal carcinoma cell line, HONE-1, by comparing 3 pairs of samples with or without WTAP knockdown.

m6A MeRIP-Seq of interscapular brown adipose tissue (iBAT) in Wtapflox/flox and BAT-specific Wtap knockout (BKO) mice

Project description:Purpose: Through mRNA m6A-profiling, we aim to characterize the mRNA m6A changes in iBAT obtained from Wtapflox/flox and Wtap-BKO mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from iBAT of Wtap flox/flox and Wtap-BKO mice at 8 weeks old. Each sample (300 μg total RNA) was pooled from 8 mice for each group. Poly(A)+ RNA was purified using Dynabeads™ mRNA Purification Kit (Invitrogen) following the manufacturer’s instructions. Fragmented mRNA was incubated with m6A antibody (Synaptic System, 202003) for immunoprecipitation. Then, immunoprecipitated mRNAs or Input was used for library construction with NEBNext ultra RNA library prepare kit for Illumina (New England Biolabs).The library preparations were sequenced on an Illumina Novaseq 6000 platform with a paired-end read length of 150 bp according to the standard protocols. The m6A peaks were detected by exomePeak R package (version 2.16.0). The motif search was detected by HOMER(version 4.9.1). Conclusion: The iBAT mRNA m6A profiles in Wtapflox/flox and BKO mice were characterized.
