The CpG island in the murine foxl2 proximal promoter is differentially methylated in primary and immortalized cells.

ABSTRACT: Forkhead box L2 (Foxl2), a member of the forkhead transcription factor family, plays important roles in pituitary follicle-stimulating hormone synthesis and in ovarian maintenance and function. Mutations in the human FOXL2 gene cause eyelid malformations and premature ovarian failure. FOXL2/Foxl2 is expressed in pituitary gonadotrope and thyrotrope cells, the perioptic mesenchyme of the developing eyelid, and ovarian granulosa cells. The mechanisms governing this cell-restricted expression have not been described. We mapped the Foxl2 transcriptional start site in immortalized murine gonadotrope-like cells, LβT2, by 5' rapid amplification of cDNA ends and then PCR amplified approximately 1 kb of 5' flanking sequence from murine genomic DNA. When ligated into a reporter plasmid, the proximal
