Fig. 11. Experimental activation of “shadow interactome” in Gallus gallus.
a Histogram (top left) shows the distribution of palindrome size in gga-miRHR region. Box plot (top right) shows ΔG for miR-4673/gga-miRHR hybridisation. The gga-miRHR genes are central to several developmental signalling networks interfacing at Wnt cascade. Amongst gga-miRHR genes several NPS from the Wnt cascade nearly achieved structural features of functional miRNAs. b Application of miR-4673 and activation of the identified gga-miRHR shadow interactome boosted angiogenic activity in chorio-allantoic membrane (top). Blue pseudo-colourised elements demonstrate expansion of microvessels (black arrow) along with increased hematopoiesis. The miRNA also amplified hematopoiesis (red pseudo-colour) and neurogenesis (black arrows) in the explanted embryo (frontal cortex: white arrow) (error bars: s.d; ** indicates p < 0.01).
