Phylogenetic, biochemical, and genetic techniques reveal a novel and ancient member of the Perilipin family, termed Plin6, that functions to concentrate and traffic lipophilic skin pigment in teleost fish.
In this episode we hear about biomarkers for epilepsy, how fish can recognise faces, insect anti-anti aphrodisiacs, and why striving for novelty may hinder the progress of science.
A physical niche for neural stem cells is generated by the induction of the immediate skin epithelium, a process triggered by the arrival of neural precursors during sensory organ formation in medaka.
The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.
Müller glia cells in the medaka (Oryzias latipes) retina act as lineage restricted progenitors which only regenerate photoreceptors but can be activated to perform as potent stem cells using Sox2.
