Using a genetic interference approach we further identify bmp2b and bmp5 as crucial components of the endodermal signals that induce epibranchial neurogenesis. Paper-11159040.
The requirement for pou2 to initiate bmp2b expression can therefore be bypassed by releasing the repressive function of Fgf signaling upon bmp2b transcription. Paper-12047657.
Moreover, swirl(tc300), a null mutation in bmp2b, is epistatic to ogo(m60) mutation, providing further evidence that ogo normally functions in a BMP-dependent manner. Paper-8296906.

Double mutant snailhouse/ bmp7; swirl/ bmp2b embryos do not exhibit additional or stronger dorsalized phenotypes, indicating that these Bmp ligands do not function redundantly in early embryonic development. Paper-2149287.
Indeed, maternal pou2 function is necessary to initiate zygotic expression of ventrally expressed genes such as bmp2b and bmp4, and for proper activation of bmp7, vox, vent and eve1. Paper-12047657.
Conversely, injected mRNA encoding a constitutively active version of Alk8 can rescue the strong dorsalization of bmp2b/swirl and bmp7/snailhouse mutants, whereas smad5/ somitabun mutant embryos do not respond. Paper-8711339.
In a search for factors differentially expressed in swirl/ bmp2b mutants compared with wild type, we isolated zebrafish Sizzled, a member of the secreted Frizzled-related protein family and putative Wnt inhibitor. Paper-9825687.
Notably, Bozozok appears to function by repressing transcription of target genes such as swr ( bmp2b) gene, and as such is the earliest acting repressor that the nascent dorsal axis is using to antagonize ventral influences. Paper-8773388.
Further observations indicate that the bmp2 gene, in addition to being expressed in the same cells of the basal layer of the epidermis as shh, is also expressed in a subset of the ptc1-expressing cells of the blastema. Paper-1643950.
The boz gene is activated in the organizer in response to beta-catenin signaling, and Boz protein has been demonstrated to contribute to organizer formation by repression of ventralizing genes, including bmp2b, vega1, and vega2. Paper-10190205.
A much stronger dorsalization, similar to that of bmp2b/swirl and bmp7/snailhouse mutants, however, is obtained by inhibiting both maternally and zygotically supplied alk8 gene products with morpholino antisense oligonucleotides. Paper-8711339.
Double mutant analyses and RNA injection experiments show that sbn and bmp2b interact and that sbn acts downstream of Bmp2b signaling to mediate Bmp2b autoregulation during early dorsoventral (D-V) pattern formation. Paper-1882735.
By analyzing genes whose expression is very sensitive to BMP signaling levels, we found that the absence of Ogon or Chordin antagonism did not increase the BMP activity remaining in swirl/ bmp2b or hypomorphic snailhouse/ bmp7 mutants. Paper-9440522.
Similar to the BMP antagonist chordino, we found that the BMP ligand mutants swirl/ bmp2b and snailhouse/ bmp7 are also epistatic to the putative BMP pathway antagonist, ogon, excluding a class of intracellular antagonists as candidates for ogon. Paper-9440522.

We demonstrate that the snailhouse/ bmp7 null mutant phenotype is identical to the presumptive null mutant phenotype of the strongest dorsalized zebrafish mutant swirl/ bmp2b, revealing equivalent genetic roles for these two Bmp ligands. Paper-2149287.
Gene co-expression during segmentation (5.5-6.5 mm SL) is similar between tetrapods and zebrafish: bmp2b, bmp4, chordin, and gdf5 in interradial mesenchyme and ZS; bapx1, col2a1, noggin3, and sox9a in chondrocytes. Paper-12588982.
However, simultaneous knockdown of mini fin and bmp1 results in severe dorsalization resembling the Swirl (swr) and Snailhouse (snh) phenotypes; caused by defects in major zebrafish ventralizing genes bmp2b and bmp7, respectively. Paper-12173049.
In the present study, we have used dorsalized swirl ( bmp2b) and ventralized chordino ( chordin) zebrafish mutants to investigate the effects of dorsoventral signalling on endoderm patterning and on the differentiation and positioning of its derivatives. Paper-9628546.
The analysis of Radar overexpression in both swirl/ bmp2b mutants and embryos expressing truncated BMP receptors shows that Radar-induced ventralization is dependent on functional BMP2/4 pathways, and may initially rely on an Alk6-related signaling pathway. Paper-8642066.
We propose that early transcriptional repression of bmp2b by Boz is one of the first steps toward formation of a stable organizer, whereas the later-acting Bmp antagonists (e.g. Chordin, Noggin) modulate Bmp activity in the gastrula to induce patterning along the dorsoventral axis. Paper-9835204.
These results implicate shh and bmp2b signaling in the proliferation and/or differentiation of specialized bone- secreting cells in the blastema and suggest shh expression may be controlled by regulatory feedback mechanisms that define the region of bone secretion in the outgrowing fin. Paper-9165239.
A similar early role for Bmp signaling is suggested in the specification of dorsal neural cell types, since the bmp2b/swirl and bmp7/snailhouse genes are only coexpressed during gastrulation and within the tail bud, and are not found in the dorsal neural tube or overlying epidermal ectoderm. Paper-2166859.
Examination of dorsally and ventrally restricted markers during gastrulation reveals a successive reduction and reciprocal expansion in nonneural and neural ectoderm, respectively, in snailhouse, somitabun, and swirl mutant embryos, with swirl/ bmp2b mutants exhibiting almost no nonneural ectoderm. Paper-1508913.
This study reports expression patterns in the lower jaw dentition of a number of key regulatory genes such as bmp2, bmp4, and sox9 and structural genes such as col1alpha 1 and osteocalcin (= bgp, Bone Gla Protein) by means of in situ hybridization using salmon-specific, digoxygenin-labeled antisense riboprobes. Paper-12959158.
Similar to the amphibian embryo, the key patterning functions of the fish dorsal organizer (i.e., dorsalization of mesoderm, ectoderm, and coordination of gastrulation movements) are performed by secreted molecules that antagonize the ventralizing activity of the swil ( zbmp-2) and zbmp-4 gene products expressed on the ventral side of the embryo. Paper-1651035.
