This produces a large amount of MBD2a (long isoform), which promotes FZD3 activation β-catenin by competitively binding to its CpG island, enhancing HCC cell stemness and promoting tumor progression.384 HNRNP RALY (also called heterogeneous nuclear ribonucleoprotein C-like 2) has been reported to be involved in regulating a large number of ASEs in HCC.385 It is found in the cholesterol synthesis pathway that RALY cooperates with SF3B3 to play a pro-tumor role in HCC, regulating Metastasis Associated 1 (MTA1) AS mode and leading to a decrease in MTA1-S isoform expression level. Here, HNRNPC is linked to neoplasm.
