Abstract

glut12

preimplantation embryo

2-cell

glucose transport

blastocyst

In this study we report the cloning and characterisation of the mouse Glut12 gene and examine for the first time its expression pattern in the earliest stages of development. Mouse Glut12 (m Glut12) was cloned from preimplantation embryos by 5â€²RACE RT-PCR using primers designed from an EST clone corresponding to a human GLUT12 antigenic sequence after positive immunoreactivity was observed in mouse two-cell embryos by western immunoblotting. The m Glut12 gene contains an open reading frame of 1869 base pairs, potentially encoding a polypeptide of 622 amino acids. The predicted mGLUT12 protein bears all the hallmarks of the SLC2A family of hexose transporters and shares an 83% sequence homology to human GLUT12. Consistent with its human homolog m Glut12 mRNA is found highly expressed in skeletal and cardiac muscle and fat. Additionally, it was also found in the uterus and during early embryogenesis. During early development in the mouse, Glut12 expression is clearly apparent in ovulated oocytes and two-cell embryos but declines in day 3 morulae. With the exception of some Glut12 expression apparent in blastocysts, Glut12 mRNA remains at low to undetectable levels until E11. © 2004 Elsevier B.V. All rights reserved.
