BTB3-AS1, an antinsense transcript required for tumorogenicity of ovarian and colorectal cancer cells

Annotated Information

Name

BTB3-AS1: BTG3 antisense RNA 1 ASBEL [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 [2]

ASBEL is transcribed from the DNA strand opposite to ANA/BTG3[1].

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 [3]. 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 [3].

Regulation

β-catenin is found to directly enhance the transcription of BTB3-AS1 [3].

Disease

  • Colorectal cancer [3]
  • Ovarian carcinoma [1]

Expression

BTB3-AS1 is highly expressed in stage I–III colon cancer than in normal tissues [3].
