Fig. 4: METTL1 deficiency reduces xenograft tumor growth in vivo.

Knockdown of METTL1 inhibited HSC-1 xenograft tumor growth (A) and reduced tumor weight (B). Knockdown of METTL1 inhibited A431 xenograft tumor growth (C) and reduced tumor weight (D). E, F The protein levels of PCNA in tumor tissues were detected by IHC and western blot. The IOD of PCNA was calculated. β-Tubulin was used for the normalization control. The relative protein level was calculated. G The mRNA level of Pcna was evaluated by qRT-PCR. Data are shown as mean ± SEM. n = 5. **P < 0.01, ***P < 0.001.
