To examine the positive correlation between high SMARCD3 expression levels and increased tumour metastasis, analyses of transcriptomics and proteomics datasets4,19 revealed that patients with metastases from all types of MB and G3 exhibited higher levels of SMARCD3 mRNA and protein expression than those in patients without metastases (Fig. 1i and Extended Data Fig. 1e). Here, SMARCD3 is linked to neoplasm.
