recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...
یکی از چالش‌های فرایند انتقال ژن در ماهیان، توسعة سیستم‌هایی برای انتقال کارآمد DNA است. در این پژوهش از پروتئین‌های باکتریایی برای هدفمندسازی انتقال ژن به تیرة سلولی ماهی زبرا استفاده شده است. اگروباکتریوم با نام علمی Agrobacterium tumefaciens قادر به انتقال کارآمد DNA خود به صورت یک مجموعه DNA-Protein به سلول‌های گیاهی است. پروتئین‌های اگروباکتریوم VirD2 و VirE2 در این فرایند نقش مهمی را ایفا...
Glyphosate is a broad spectrum herbicide used aggressively in agricultural practices as well as home garden care. Although labeled "safe" by the chemical industry, doses tested by industry do not mimic chronic exposures to sublethal doses that organisms in the environment are exposed to over long periods of time. Given the widespread uses of and exposure to glyphosate, studies on developmental ...
Genome-wide chemical mutagenesis screens in the zebrafish (Danio rerio) have led to the identification of novel genes affecting vertebrate erythropoiesis. In determining if this approach could also be used to clarify the molecular genetics of myelopoiesis, it was found that the developmental hierarchy of myeloid precursors in the zebrafish kidney is similar to that in human bone marrow. Zebrafi...
The complexes formed by BCL10, MALT1 and specific members of the family of CARMA proteins (CBM complex), have recently focused much attention because they represent a central hub regulating activation of the transcription factor NF-κB following various cellular stimulations. In this manuscript, we report the functional characterization of a Danio rerio 241 amino acids polypeptide ortholog of th...
The zebrafish (Danio rerio) is increasingly being used as model in behavioural [1,2], neurobiological and genetic research [3]. Underlying reasons are high genetic homology to humans [4] and the many advantages over the use of rodents, such as low cost, easy handling, short reproduction cycle and high fecundity. Furthermore, its genome [5], transcriptome [6] and proteome [7] are well described,...
Liver is one of the largest internal organs in the body and its importance for metabolism, detoxification and homeostasis has been well established. In this review, we summarized recent progresses in studying liver initiation and development during embryogenesis using zebrafish as a model system. We mainly focused on topics related to the specification of hepatoblasts from endoderm, the formati...
Using zebrafish (Danio rerio) as a case study, we show that the maturity concept of Dynamic Energy Budget (DEB) theory is a useful metric for developmental state. Maturity does not depend on food or temperature contrary to age and to some extent length. We compile the maturity levels for each developmental milestone recorded in staging atlases. The analysis of feeding, growth, reproduction and ...
