Studies on mammalian species with naturally reduced eyes can provide valuable insights into the evolutionary developmental mechanisms underlying the reduction of the eye structures. Because few naturally microphthalmic animals have been stu...
Sex-lethal gene of the Chinese mitten crab Eriocheir sinensis: cDNA cloning, induction by eyestalk ablation, and expression of two splice variants in males and females [0.03%]
中华绒螯蟹性连锁性别决定基因sex-lethal的克隆、眼柄切除对其诱导及两种剪接变异体在雄蟹和雌蟹中的表达差异

Sex-lethal (Sxl) plays an important role in sex determination in insects. In this study, the full-length complementary DNA (cDNA) of Sxl of the Chinese mitten crab Eriocheir sinensis (EsSxl) was cloned. EsSxl is expressed during different d...
Inhibitors of the p53-Mdm2 interaction increase programmed cell death and produce abnormal phenotypes in the placozoon Trichoplax adhaerens (F.E. Schulze) [0.03%]
p53-Mdm2相互作用抑制剂增加了黏附platydonton的程序性细胞死亡并产生异常表型

Recent identification of genes homologous to human p53 and Mdm2 in the basal phylum Placozoa raised the question whether the network undertakes the same functions in the most primitive metazoan organism as it does in more derived animals. H...
Expression of arthropod distal limb-patterning genes in the onychophoran Euperipatoides kanangrensis [0.03%]
节肢动物肢芽模式基因在鳃足类Euperipatoides kanangrensis中的表达

A current hypothesis states that the ancestral limb of arthropods is composed of only two segments. The proximal segment represents the main part of the modern leg, and the distal segment represents the tarsus and claw of the modern leg. If...
Evidence for maternal imprinting of 45S ribosomal RNA genes in Xenopus hybrids [0.03%]
蛙类杂种中母系印记45S核糖体RNA基因的证据

We discovered that gene clusters of 45S ribosomal RNA in Xenopus hybrid frogs are maternally imprinted, similar to X chromosome inactivation in marsupial females. Paternal expression was partly restored after chemical inhibition of histone ...
Patterns of molecular evolution of the germ line specification gene oskar suggest that a novel domain may contribute to functional divergence in Drosophila [0.03%]
欧卡什基因分子进化模式表明在一个新型功能区在果蝇系谱发育式样中可能起到重要作用
Abha Ahuja,Cassandra G Extavour
Abha Ahuja
In several metazoans including flies of the genus Drosophila, germ line specification occurs through the inheritance of maternally deposited cytoplasmic determinants, collectively called germ plasm. The novel insect gene oskar is at the top...
Identification of the key stages for sex determination in the silkworm, Bombyx mori [0.03%]
家蚕性别的鉴定关键阶段

Hiroki Sakai
In general, the master switch gene for sex determination is expressed for a limited period during the early embryonic stage. To increase our understanding of the sex determination mechanism in Bombyx mori, it is important to understand when...
Timelines in the insect brain: fates of identified neural stem cells generating the central complex in the grasshopper Schistocerca gregaria [0.03%]
昆虫脑中的时间线：产生成蝇中央复杂的鉴定神经干细胞的命运

George Boyan
This study employs labels for cell proliferation and cell death, as well as classical histology to examine the fates of all eight neural stem cells (neuroblasts) whose progeny generate the central complex of the grasshopper brain during emb...

Pumilio proteins (PUMs), members of the pumilio/fem-3 mRNA-binding factor (PUF) family, are eukaryote-specific RNA-binding proteins. We isolated a 2,048-basepair cDNA fragment of a pumilio homolog from the planarian flatworm Polycelis sp. T...
Aryl hydrocarbon receptor (AHR) in the cnidarian Nematostella vectensis: comparative expression, protein interactions, and ligand binding [0.03%]
刺胞动物Nematostella vectensis中的芳香烃受体(AHR):表达分析、蛋白相互作用及配体结合比较

Adam M Reitzel et al.
The aryl hydrocarbon receptor (AHR) is a member of the basic helix-loop-helix/Per-ARNT-Sim (bHLH-PAS) family of transcription factors and has diverse roles in development, physiology, and environmental sensing in bilaterian animals. Studyin...
