Studies suggested that DACT2 expression in nasopharyngeal carcinoma cells is restored by TET1 which demethylates its promotor region.
Title: TET1 exerts its anti-tumor functions via demethylating DACT2 and SFRP2 to antagonize Wnt/β-catenin signaling pathway in nasopharyngeal carcinoma cells.
Results demonstrate that DACT2 is frequently inactivated epigenetically by CpG methylation in nasopharyngeal carcinoma (NPC), while it inhibits NPC cell proliferation and metastasis via suppressing beta-catenin/Cdc25c signaling. These findings suggest that DACT2 promoter methylation is a potential epigenetic biomarker for the detection of NPC.

Our findings provide a novel DACT2 demethylating stimulator to verify and expand previously established link between DACT2 and colorectal cancer (CRC), suggesting DACT2 demethylation is strongly correlated with CRC prognosis.

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.

NM_001286350.2 → NP_001273279.1 dapper homolog 2 isoform b

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks a portion of the 5' UTR and 5' coding region, and initiates translation at a downstream in-frame start codon, compared to variant 1. The encoded isoform (b) is shorter at the N-terminus, compared to isoform a.
