Induction of metamorphosis with potassium ions requires development of competence and an anterior signalling centre in the ascidian Herdmania momus [0.03%]
钾离子诱导海鞘Herdmania momus发生 competence发育和前部信号中心的变态反应

B M Degnan et al.
Increased K+ concentration in seawater induces metamorphosis in the ascidian Herdmania momus. Larvae cultivated at 24°C exhibit highest rates of metamorphosis when treated with 40 mM KCl-elevated seawater at 21°C. At 24°C, H. momus larva...
Distribution of Pax6 protein during eye development suggests discrete roles in proliferative and differentiated visual cells [0.03%]
帕克斯六蛋白在眼发育过程中的分布暗示了其在增殖和分化视觉细胞中起着不同的作用

Although Pax6 is required during eye development in rodents and humans, little is known about the precise role of the protein in this process. To aid in the interpretation of functional studies, we have determined the precise spatial and te...
Thyroid hormone-dependent repression of α1-microglobulin/bikunin precursor (AMBP) gene expression during amphibian metamorphosis [0.03%]
甲状腺激素诱导两栖类变态时期AMBP基因表达下降研究
A Kawahara,Akira Hikosaka,T Sasado et al.
A Kawahara et al.
A Xenopus AMBP (xAMBP) cDNA clone was isolated from a subtracted liver cDNA library by differential hybridization screening. The deduced amino acid sequence shared 50-60% identity with its mammalian counterparts, which are the precursors of...
Expression of a zebrafish Cathepsin L gene in anterior mesendoderm and hatching gland [0.03%]
斑马鱼Cathepsin L基因在前肠内胚层和孵化腺中的表达

Andreas M Vogel
During a differential display-based screen for developmentally regulated genes in zebrafish, we have isolated a cDNA for zebrafish cathepsin L, termed catL. The gene shows abundant expression in the anteriormost cells of the head process wh...
Skeletogenic potential of induced secondary mesenchyme cells derived from the presumptive ectoderm in echinoid embryos [0.03%]
海胆胚中来源于预构外胚层的诱导产生的次生间充质细胞的骨化潜能

T Minokawa
During the normal development of echinoids, an animal cap consisting of 8 mesomeres in a 16-cell stage embryo differentiates exclusively into ectoderm. Micromeres in an embryo at the same stage differentiate into primary mesenchyme cells (P...
Muscle-specific regulation of tropomyosin gene expression and myofibrillogenesis differs among muscle systems examined at metamorphosis of the gastropod Haliotis rufescens [0.03%]
海扇贝Haliotis rufescens变态期不同肌肉系统中肌动蛋白基因表达及肌原纤维生成的肌肉特异性调节差异
B M Degnan,Sandie M Degnan,Daniel E Morse
B M Degnan
The spatial and temporal association of muscle-specific tropomyosin gene expression, and myofibril assembly and degradation during metamorphosis is analyzed in the gastropod mollusc, Haliotis rufescens. Metamorphosis of the planktonic larva...
Transient expression of a novel serine protease in the ectoderm of the ascidian Herdmania momus during development [0.03%]
海鞘Herdmania momus在发育过程中外胚层中新型丝氨酸蛋白酶的瞬时表达
J M Arnold,C Kennett,Bernard M Degnan et al.
J M Arnold et al.
We have studied gene expression during ascidian embryonic development using the technique of differential display and isolated partial cDNA sequences of 12 genes. Developmental regulation of these genes has been confirmed by northern hybrid...
Pair-rule patterning in the honeybee Apis mellifera: Expression of even-skipped combines traits known from beetles and fruitfly [0.03%]
意蜂蜜蜂Apis mellifera的偶数规则图案：even-skipped的表达结合了甲虫和果蝇已知的特征
P Binner,Klaus Sander
P Binner
We have studied the binding pattern of antibody mAB 2B8 directed against even-skipped orthologous proteins (EVE) in honeybee embryos. Primary and secondary EVE stripes form in roughly anterior-to-posterior succession; there are 8 primary an...
Expression of HvRACK1, a member of the RACK1 subfamily of regulatory WD40 proteins in Hydra vulgaris, is coordinated between epithelial and interstitial cells in a position-dependent manner [0.03%]
水螅HvRACK1的表达方式是一种WD40调节亚科成员，在表皮细胞和间充质细胞之间以位置依赖性方式进行协调的方式表达
Martin R Hornberger,M Hassel
Martin R Hornberger
A gene encoding a member of the growing family of regulatory WD-repeat proteins has been identified in Hydra vulgaris. About 80% of its deduced amino acids are identical to RACK1, which has recently been identified in rat as a receptor for ...
Planarian pharynx regeneration in regenerating tail fragments monitored with cell-specific monoclonal antibodies [0.03%]
