Title: Pattern of transcription of the homeo gene Hox-3.1 in the mouse embryo. Author: Le Mouellic H, Condamine H, Brûlet P. Journal: Genes Dev; 1988 Jan; 2(1):125-35. PubMed ID: 2895723. Abstract: A cDNA from the Hox-3.1 locus, isolated from a 10.5-day postcoitum (p.c.) mouse embryo cDNA library, and the putative encoded protein are described. The spatial distribution of Hox-3.1 gene transcripts from late gastrulation to embryonic day 14.5 p.c. was monitored by in situ hybridization, using a cDNA probe. When first detectable in 8.5-day p.c. embryos, the transcripts are distributed in all the tissues of the posterior end. At later stages, the distribution becomes progressively spatially restricted and tissue specific. By 12.5 days p.c., transcription is localized most intensely in the neural tube region lying above the heart. The early transcription pattern thus appears to be compatible with a regionalizing role for the Hox-3.1 gene.[Abstract] [Full Text] [Related] [New Search]
