DEC1, a candidate tumor suppressor in 9q32
Contents
Annotated Information
Name
DEC1: deleted in esophageal cancer 1
Characteristics
BTB3-AS1 is a member of the TOB/BTG family of antiproliferative genes that regulates cell cycle progression in a variety of cell types
BTB3-AS1 is an antisense transcript of ANA/BTG3. it is a highly conserved gene encoded by the DNA strand opposite the ANA/BTG3 gene.
Function
In ovarian carcinoma, BTB3-AS1 promotes tumorigenesis through suppressing translation of the sense gene (ANA/BTG3) [1]. BTB3-AS1 forms duplexes with ANA/BTG3 mRNA in the nucleus and suppresses its cytoplasmic transportation, leading to negative regulation of ANA/BTG3 at protein level without changing of its mRNA level [1]. BTB3-AS1 also plays a key role in Wnt/β-catenin-mediated tumorigenesis [2]. BTB3-AS1 interacts with and recruits transcription factor 3 (TCF3) for activating transcription factor 3 (ATF3) locus and represses the expression of ATF3, resulting in proliferation and tumorigenicity of colon tumor cells [2].
Regulation
β-catenin is found to directly enhance the transcription of BTB3-AS1 [2].
Disease
Expression
BTB3-AS1 is highly expressed in stage I–III colon cancer than in normal tissues [2].
