A Restriction Endonuclease-Based Assay to Distinguish NANOGP8 Retrogene from Parental NANOG

Hamida Thakur et al. Methods Mol Biol. 2021.

Abstract

NANOG is an embryonic transcription factor, which gets reexpressed in cancer stem or tumor initiating cells. NANOGP8, a retrogene belonging to the NANOG family, is predominantly expressed in cancer cells and shows very high similarity with NANOG both at the nucleotide and at the protein level. The high similarity makes it extremely challenging to distinguish between these two transcription factors. Here we describe a highly efficient restriction endonuclease-based assay, which is performed on cDNA and allows to distinguish NANOGP8 from NANOG. This assay is critical to understand the specific role of NANOGP8 in cancer stemness, which in turn helps to unravel the therapeutic potential of targeting this undruggable transcription factor through gene therapy, for treatment of various cancers.

Keywords: AlwNI restriction endonuclease; NANOG; NANOGP8; Pseudogene.
