哺乳动物基因组编码大量反义非编码RNA,这些RNA被认为参与有义基因表达的调节。然而,它们的作用机制和参与疾病发展的机制尚未得到很好的阐明。 ANA/BTG3 蛋白是一种抗增殖蛋白,其表达在前列腺癌和肺癌中下调。在这里,我们发现 ANA/BTG3 基因的反义转录本(称为 ASBEL)负向调节 ANA/BTG3 蛋白的水平,但不负向调节 ANA/BTG3 mRNA 的水平,并且是卵巢透明细胞癌增殖和致瘤性所必需的。我们进一步表明,ANA/BTG3 的敲低可以挽救 ASBEL 敲低引起的生长抑制。此外,我们证明 ASBEL 与细胞核中的 ANA/BTG3 mRNA 形成双链体并抑制其细胞质运输。我们的研究结果说明了反义转录物的一种新功能,它通过抑制有义基因的细胞质运输来抑制有义基因的翻译,从而严重促进肿瘤发生。
Mammalian genomes encode numerous antisense non-coding RNAs, which are assumed to be involved in the regulation of the sense gene expression. However, the mechanisms of their action and involvement in the development of diseases have not been well elucidated. The ANA/BTG3 protein is an antiproliferative protein whose expression is downregulated in prostate and lung cancers. Here we show that an antisense transcript of the ANA/BTG3 gene, termed ASBEL, negatively regulates the levels of ANA/BTG3 protein, but not of ANA/BTG3 mRNA and is required for proliferation and tumorigenicity of ovarian clear cell carcinoma. We further show that knockdown of ANA/BTG3 rescues growth inhibition caused by ASBEL knockdown. Moreover, we demonstrate that ASBEL forms duplexes with ANA/BTG3 mRNA in the nucleus and suppresses its cytoplasmic transportation. Our findings illustrate a novel function for an antisense transcript that critically promotes tumorigenesis by suppressing translation of the sense gene by inhibiting its cytoplasmic transportation.
