Figure Lengend Snippet: METTL3 reduces TACSTD2 mRNA stability via an m6A-YTHDC2-dependent signaling. A : Prediction of m6A sites of TACSTD2 by SRAMP database. B : Analyzing m6A modification sites in the TACSTD2 coding sequence region through database. C : METTL3 expression level of THCA in GEPIA2 databases. D : RT-qPCR was used to evaluate the mRNA level adjusted to GAPDH of methyltransferases and demethylases in THCA and paired tissues. The expression levels of TACSTD2 in METTL3-overexpressing and METTL3 knockdown PTC cells were detected by WB (E) and qRT-PCR (F) . G : MeRIP-qPCR analysis was employed to demonstrate METTL3-mediated TACSTD2 m6A modifications. The m6A modification of TACSTD2 was increased on upregulation of METTL3, while it was depleted on METTL3 silencing. H-I : TACSTD2 mRNA level in METTL3-overexpressing PTC cells treated with actinomycin D at the indicated time points were detected by qRT-PCR. METTL3 overexpression reduced the half-life of TACSTD2 transcript. J : YTHDC2 expression level of THCA in GEPIA2 databases. K : RT-qPCR was used to evaluate the mRNA level adjusted to GAPDH of N6-methyladenosine readers in THCA and paired tissues. L : The expression levels of TACSTD2 in YTHDC2-overexpressing PTC cells were detected by qRT-PCR. M : The expression levels of TACSTD2 in YTHDC2-overexpressing and YTHDC2 knockdown PTC cells were detected by WB. N : RIP-qPCR evaluated enrichment level of TACSTD2 in PTC cells after YTHDF2 knockdown. O : TACSTD2 mRNA level in YTHDC2 overexpression PTC cells treated with actinomycin D at the indicated time points were detected by qRT-PCR. YTHDC2 overexpression reduced the half-life of TACSTD2 transcript. P: WB was used to assess TACSTD2 level in PTC cells transfected with NC or OE-METTL3 with sh-NC or sh-YTHDC2.

Article Title: CircYthdc2 generates polypeptides through two translation strategies to facilitate virus escape

doi: 10.1007/s00018-024-05148-9

Figure Lengend Snippet: Schematic diagram of the mechanism underlying Ythdc2-170aa and Ythdc2 both promoted K11 and K48-linked ubiquitination of STING. Under normal circumstances, circYthdc2 does not translate to produce polypeptides. When SCRV virus infects the host, the pathway of circYthdc2 translating polypeptides is activated. There are two pathways for circYthdc2 to be translated into polypeptides, the one is IRES-mediated translation pathway and another m 6 A modification mediated translation pathway. In addition, Ythdc2 will preferentially promote the RNA degradation of circYthdc2 when circYthdc2 is produced in large quantities. Ythdc2-170aa and Ythdc2 both could promote the STING protein degradation and represses STING-mediated antiviral responses, thereby regulating viral replication. Ythdc2-170aa and Ythdc2 both promoted K11 and K48-linked ubiquitination of STING, thereby inhibited the antiviral responses and help the virus escape
