What's a GeneRIF?

beta-GP induced VSMC calcification by activating the Wnt/beta-catenin signaling pathway. Sclerostin and Lrp4 were involved in beta-GP-induced VSMC calcification and play an important role. GBE could alleviate VSMC calcification induced by beta-GP through inhibiting the Wnt/beta-catenin signaling pathway.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
