Transcriptome and Proteome analysis of Hemidactylus frenatus during initial stages of tail regeneration
2019
Epimorphic regeneration of appendages is a complex and complete phenomenon found in selected animals. Hemidactylus frenatus, the common house gecko has the remarkable ability to regenerate the tail tissue upon autotomy involving epimorphic regeneration mechanism. This study has identified and evaluated the molecular changes at gene and protein level during the regeneration of tail tissue. Based on next generation transcriptomics and De novo analysis the transcriptome and proteome library of the gecko tail tissue was generated. A total of 417 genes and 128 proteins were found to be associated with the regeneration of gecko tail tissue upon amputation at 1, 2 and 5-day post amputation against control, 0dpa through differential analysis. The differentially expressed genes and proteins expressed a similar pattern for the commonly identified 36 genes/proteins involved in regeneration of the tail tissue. Similarly, the expression analysis of 50 genes were further validated involving real time PCR to authenticate the transcriptomics analysis. 327 genes/proteins identified from the study showed association for GP6 signaling pathway, Protein kinase A signaling, Telomerase signaling BAG2 signaling, paxiling signaling, VEGF signaling network pathways based on network pathway analysis. This study empanelled list of genes/proteins associated with tail tissue regeneration and its association for the mechanism.
