Project description:MicroRNAs (miRNAs) are 18-24 nucleotide autonomous regulatory RNA molecules found in all eukaryotes. They are involved in the regulation of a multitude of genetic and biological pathways through post transcriptional gene silencing and/or translational repression. Previous data has suggested a slow evolutionary rate for the saltwater crocodile (Crocodylus porosus) over the past several million years when compared to its closest extant relatives, the birds. Understanding genome regulation, adaptive capabilities and physiological features in the saltwater crocodile in the context of relatively slow genomic change thus holds significant potential for the investigation of genomics, evolution and adaptive studies. Utilizing eleven different tissue types and sixteen small RNA libraries, we report a catalog of 644 miRNAs in the saltwater crocodile with > 78% of miRNAs being potentially novel to crocodilians. We also predicted and identified targets for the miRNAs as well as analyzed the relationship of the miRNA repertoire to transposable elements (TEs) in the saltwater crocodile that showed an increased association of DNA transposons with miRNA biogenesis when compared to retrotransposons. Phylogenetic analysis of C. porosus miRNA expectedly revealed highest number of miRNAs in sister crocodilian clades of the American Alligator and the Indian Gharial. This work reports the first comprehensive analysis of miRNAs in Crocodylus porosus for and addresses the potential impacts of miRNAs in regulating the genome in the saltwater crocodile as well as supporting the role of TEs as a source for miRNAs, adding to the increasing evidence that TEs play a significant role in the evolution of gene regulation.

Project description:In a reproductive strategy that is considered unique to the mammalian lineage, spermatozoa must undergo a series of physiological changes, termed capacitation, in the female reproductive tract prior to developing their capacity to fertilize an ovum. Here, we have employed a comparative proteomic strategy to explore the biological significance of this form of post-testicular maturation in the ancient reptilian species of the Australian saltwater crocodile (Crocodylus porosus).

Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).
