Project description:Needle in a haystack? A comparison of eDNA metabarcoding and targeted qPCR for detection of great crested newt (Triturus cristatus)
Project description:The adult vertebrate red spotted newt is a champion of regeneration, demonstrating an amazing ability to regenerate damaged organs and tissues back to an uninjured state without the formation of scar or reduction in function. By developing a novel cardiac resection strategy, our group recently demonstrated that newt hearts could morphologically and functionally regenerate, without scarring, within a period of 2-3 months following injury. MicroRNAs (miRs) have been widely publicized as essential post-transcriptional gene regulators in a variety of biological processes, including regeneration. We have conducted a microarray screen for vertebrate miRs, with several candidate miRs showing significant differential expression at important time-points following injury to the newt heart. The newt microRNA expression between uninjured hearts and regenerating hearts, 7 and 21 days post-injury (dpi), was compared by microarray analysis. Three paired samples were analyzed: Uninjured, 7dpi and 21dpi newt hearts. Three arrays were hybridized comparing two-paired samples each time.
