Brain fuel usage is governed by developmental stage, fuel availability, physiological state and biochemical regulatory mechanisms, as well as disease state.
Given the transparency of the zebrafish during early developmental stages, the availability of transgenic fluorescent reporter lines and the conservation of the principal components of the innate immune system, it is now possible to study immunity by following the behavior of infiltrating cells in the living animal.
The availability of developmental markers would allow rapid comparisons to be made between leaves thought to be at the same developmental state to confirm whether like is being compared with like.
Ten candidate reference genes were screened from four ubiquitously expressed gene families by analyzing public microarray data sets that included profiles of multiple organs, developmental stages, and water availability status in rice.
A translucent morphology, availability of developmental mutants, quickly spawning embryos, established transgenic, morpholino-based gene knockdown, in situ hybridization experimental procedures and extensive EST data are some of the many advantages that make Ciona an excellent model organism to study developmental and evolutionary biology of the vertebrate-invertebrate split.
Another line of evidence implicating this family in integration of developmental, stress, and nutrient availability signals, comes from expression data.
Instead, the reactions that link individual sugar units are influenced by factors that include cellular metabolism, cell type, developmental stage, and nutrient availability.
This integration remains highly challenging because model systems offering a rich ecological and evolutionary background, together with the availability of developmental genetic tools and genomic resources, are scarce.
Concentration or spatiotemporal availability of developmental regulators might constitute a difference in regeneration capability between mammals and teleosts (Kawakami et al. 2006).
A translucent morphology, availability of developmental mutants, established transgenic experimental procedures, EST databases and quickly spawning embryos are just a few advantages that make Ciona a favourite model system for developmental biologists.
