For RNA-seq library preparation, mRNA was enriched using the Dynabeads mRNA Purification Kit (Invitrogen), followed by library construction with the MGIEasy RNA Library Prep Kit and MGIEasy Circularization Module V2.0 (MGI). Paired-end sequencing (2  150 bp) was performed on a DNBSEQ-G400 platform (MGI) with the DNBSEQ-170 G400RS High-throughput Sequencing Set, yielding 30.7- 46.5 million reads per sample.
