Analysis of the human and murine transcriptomes has identified long noncoding RNAs (lncRNAs) as major functional components in both species. Transcriptional profiling of the murine limb led to our discovery of lncRNA‐HIT, which our previous in vitro analyses suggested a potential role for this lncRNA in the development of limb, craniofacial, and genitourinary tissues (Carlson et al., 2015). To test...
To investigate microRNA (miR) functions in early eye development, we asked whether eye field transcription factors (EFTFs) are targets of miR‐dependent regulation in Xenopus embryos. Argonaute (AGO) ribonucleoprotein complexes, including miRs and targeted mRNAs, were coimmunoprecipitated from transgenic embryos expressing myc‐tagged AGO under the control of the rax1 promoter; mRNAs for all EFTFs coimmunoprecipitated...
Primordial germ cells (PGCs) are the precursors to the adult germline stem cells that are set aside early during embryogenesis and specified through the inheritance of the germ plasm, which contains the mRNAs and proteins that function as the germline fate determinants. In Drosophila melanogaster, formation of the PGCs requires the microtubule and actin cytoskeletal networks to actively segregate...
Oxygen (O2) homeostasis is essential to the metazoan life. O2‐sensing or hypoxia‐regulated molecular pathways are intimately involved in a wide range of critical cellular functions and cell survival from embryogenesis to adulthood. In this report, we have designed an innovative hypoxia sensor (O2CreER) based on the O2‐dependent degradation domain of the hypoxia‐inducible factor‐1α and Cre recombinase...
The ear drum, or tympanic membrane (TM), is a key component in the intricate relay that transmits air‐borne sound to our fluid‐filled inner ear. Despite early belief that the mammalian ear drum evolved as a transformation of a reptilian drum, newer fossil data suggests a parallel and independent evolution of this structure in mammals. The term “drum” belies what is in fact a complex three‐dimensional...
A previous animal study by our group found that sleep deprivation during preimplantation was associated with decreased pregnancy maintenance. Given its impact on human society, we aimed in the current study to assess whether sleep deprivation affects blastocyst gene expression and/or the implantation process. For this, pregnant mice (gestational day 0 [GD 0]) were assigned into paradoxical sleep deprivation...
