Project description:Lizards cannot naturally regenerate limbs but are the closest known relatives of mammals capable of epimorphic tail regrowth. However, the mechanisms regulating lizard blastema derivation and chondrogenesis remain unclear. We utilized single-cell RNA sequencing analyses of regenerating lizard tails throughout the course of regeneration to assess diversity and heterogeneity in regeneating tail cell populations.

Project description:Protemics of anolis carolinensis tails undergoing regeneration.
As amniote vertebrates, lizards are the most closely related organisms to humans capable of appendage regeneration. Lizards can autotomize, or release their tails as a means of predator evasion, and subsequently regenerate a functional replacement. Green anoles (Anolis carolinensis) can regenerate their tails through a process that involves differential expression of hundreds of genes, which has previously been analyzed by transcriptomic and microRNA analysis. To investigate protein expression in regenerating tissue, we performed whole proteomic analysis of regenerating tail tip and base. This is the first proteomic data set available for the green anole lizard. We identified 976 proteins only in the regenerating tail base, 796 only in the tail tip, and 874 in both tip and base. For 90% of these proteins in these tissues, we were able to assign a clear orthology to gene models in either the Ensembl or NCBI databases. For 20 proteins in the tail base (2.5%), 7 proteins in the tail tip (0.9%), and 7 proteins in both regions (0.8%), the gene model in Ensembl and NCBI matched an uncharacterized protein, confirming that these predictions are present in the proteome. Ontology and pathways analysis of proteins expressed in the regenerating tail base identified categories including actin filament-based process, ncRNA metabolism, regulation of phosphatase activity, small GTPase mediated signal transduction, and cellular component organization or biogenesis. Analysis of proteins expressed in the tail tip identified categories including regulation of organelle organization, regulation of protein localization, ubiquitin-dependent protein catabolism, small GTPase mediated signal transduction, morphogenesis of epithelium, and regulation of biological quality. These proteomic findings confirm pathways and gene families activated in tail regeneration in the green anole as well as identify uncharacterized proteins whose role in regrowth remains to be revealed.

Project description:Anolis carolinensis embryos were collected 0-1 days post egg laying, and total RNA was extracted for RNA-Seq analysis (Illumina Hi-Seq2000). Transcriptome sequence from these stages in the green anole, equivalent to mouse 9.5-10.5 dpc embryos, will help to improve gene annotations in A. carolinensis and provide expression level information for key organogenesis and patterning processes. Anolis carolinensis embryos were collected 0-1 days post egg laying for RNA-Seq analysis. The two embryos collected were at 28 somite-pair (28S) and 38 somite-pair (38S), equivalent to mouse 9.5 dpc and 10.5 dpc embryos, respectively. Total RNA was extracted using the total RNA component of the mirVana (Ambion) kit, RNA-Seq library prep was carried out using the NuGEN Ovation RNA-Seq kit, and sequencing was carried out on an Illumina HiSeq 2000, following the manufacturer's protocol. The untrimmed data was then aligned to the Anolis carolinensis reference genome (Anocar2.0) using tophat.
