...Mariko Kikuchi; Miyo Yoshimoto; Tokiro Ishikawa; Yuto Kanda; Kazutoshi Mori; Toshiya Nishimura; Minoru Tanaka ABSTRACT Gametogenesis is the process through which germ cells differentiate into sexually dimorphic gametes, eggs and sperm. In the teleost fish medaka ( Oryzias latipes ), a germ cell...

... approaches. We demonstrate the applicability of the inception concept in medaka ( Oryzias latipes ) in three settings: loss of function, by introducing a pre-termination STOP codon in the open reading frame of oca2 ; locally confined multi-codon changes to generate allelic variants with different phenotypic...

We modelled a putative hypomorphic mutation described in an alpha-1,3/1,6-mannosyltransferase (ALG2) index patient (ALG2-CDG) to address the developmental consequences in the teleost medaka ( Oryzias latipes ). We...

... in the neuroretina of medaka fish ( Oryzias latipes ), a well-studied system with which to address vertebrate organ growth. We reveal that a central growth regulator, Igf1 receptor (Igf1r), is necessary and sufficient for proliferation control in the postembryonic retinal stem cell niche: the ciliary marginal zone...

... genetic programs that can interact with each other during embryogenesis. Here, we have taken advantage of the different span of embryonic development between two distantly related teleosts, zebrafish ( Danio rerio ) and medaka ( Oryzias latipes ) (3 and 9 days, respectively), to explore modularity...

... of the brain in this process is not well clarified. In the present work, we investigated the mRNA levels of corticotropin-releasing hormone b ( crhb ) and its receptors ( crhr1 and crhr2 ), and found that they were upregulated at HT during the crucial period of gonadal sex determination in medaka. In order...

... specification in progenitors that exit the stem cell niche in the ciliary marginal zone (CMZ). The proper cell-type composition arising from those progenitors is a prerequisite for retinal function. Our findings in the teleost medaka ( Oryzias latipes ) uncover that the Notch-Atoh7 axis continuously patterns...

Recently, transplantation experiments involving permanently labeled cells revealed multipotent neural stem cells (NSCs) of embryonic origin in the medaka retina. To analyze whether NSC potency is affected by developmental progression...

We found that a subset of hypomethylated domains harbor H3K27me3 (K27HMDs) and their size positively correlates with the accumulation of H3K27me3. Large K27HMDs are conserved...

We found that mutations of the guanine nucleotide exchange factor ArhGEF18 affect apicobasal polarity of the retinal neuroepithelium in medaka fish. We show that ArhGEF18 -mediated activation of the small GTPase RhoA is required to maintain apicobasal...

To address this issue, we focused on the homeobox TF Six3.2 . With genomic and functional approaches we demonstrate that, in medaka fish...

However, the identity of the pathways by which nodal flow is interpreted remains controversial as the molecular sensors of this process are unknown. In the current study, we show that the medaka left-right...
