Circadian clockwork genes are expressed in the reproductive tract and conceptus of the early pregnant mouse

MH Johnson, A Lim, D Fernando, ML Day - Reproductive biomedicine …, 2002 - Elsevier
Circadian genes are expressed in some peripheral tissues, but the expression status of the
female reproductive tract and the conceptus over the preimplantation period is unknown.
Oocytes, uterine, oviducal tissues and preimplantation conceptuses from days 1–4 of mouse
pregnancy were analysed for transcript presence by reverse transcription polymerase chain
reaction. Transcripts encoded by the seven known mammalian canonical circadian genes
(Per1–3, Cry1–2, Bmal1 and Clock), plus the mammalian genetic homologue of the …
