Total RNA sequencing of the liver tissues of Oreochromis niloticus (Nile Tilapia) and of Pundamilia nyerei

Project description:Cichlids fishes exhibit extensive phenotypic diversification and speciation. In this study we integrate transcriptomic and proteomic signatures from two cichlids species, identify novel open reading frames (nORFs) and perform evolutionary analysis on these nORF regions. We embark comparative transrcriptomics and proteogenomic analysis of two metabolically active tissues, the testes and liver, of two cichlid species Oreochromis niloticus (Nile tilapia, ON) and Pundamilia nyererei (Makobe Island, PN). Our results suggest that the time scale of speciation of the two species can be better explained by the evolutionary divergence of these nORF genomic regions.

Genome-wide microRNA screening in Nile tilapia reveals pervasive transcription of isomiRs, sex-biased arm switching and increasing complexity of expression throughout development

Project description:The elucidation of microRNA function and evolution depends on the identification and characterization of miRNA repertoire of strategic organisms, as the fast evolving cichlid fishes. Using RNA-seq and comparative genomics we carried out an in-depth report of miRNAs in Nile tilapia (Oreochromis niloticus). Our results enlarge vertebrate miRNAs collection and reveal a notable differential expression of miRNAs arms and isoforms influenced by sex and developmental life stage, providing a better picture of the evolutionary and spatiotemporal dynamics of miRNAs.

Leptin stimulates cellular glycolysis through a STAT3 dependent mechanism in tilapia

Project description:Purpose: The goal of this study was to assess the differential gene expression between control and leptin treated pituitary rostral pars distalis' of the tilapia (Oreochromis mossambicus). Methods: Pituitary mRNA profiles from control (PBS) and leptin (100nM) treated tilapia (Oreochromis mossambicus) pituitary rostral pars disatalis were generated by deep sequencing using Illumina MiSeq. The sequence reads that passed quality filters were analyzed at the transcript abundance level using ANOVA (ANOVA) and BowTie2 followed by Cufflinks. Results: Differential gene expression identified 1995 genes that were differentially expressed in the pituitary rostral pars distalis treated with leptin compared to PBS treated controls. These genes were indicated to be functionally involved in numerous biological processes including glycolyiss. Conclusions: Our study represents the first detailed pituitary rostral pars distalis transcriptomes in the tilapia and identifies leptin as a major stimulator of glycolysis at the cellular level in teleost fishes.

Development of gene expression signatures for the HDF and MDA-MB-231 cells that received TP4 (a cationic antimicrobial peptide) treatment

Project description:Triple-negative breast cancer (TNBC) lacks therapeutic target and is difficult to treat. We report a cationic antimicrobial peptide (CAP), tilapia piscidin 4 (TP4), derived from Nile tilapia (Oreochromis niloticus), selectively toxic to TNBC. Here we aim to identify potential target in TNBC cell response to TP4 treatment by microarray study and to further address the role of TP4-resposive genes involved in TNBC cell death.

Global DNA methylation changes in Nile tilapia gonad during high-temperature induced masculinization

Project description:In fish, the sex determining mechanisms can broadly be classified as genotypic (GSD), temperature-dependent (TSD), or genotypic plus temperature effects (GSD+TE). For the fish species with TSD or GSD+TE, extremely high or low temperature can affect its sex determination and differentiation. For long time, the underlying changes in DNA methylation that occur during high or low temperature induced sex reversal have not been fully clarified. In this study, we used Nile tilapia as a model to perform a genome-wide survey of differences in DNA methylation in female and male gonads between control and high temperature induced groups using methylated DNA immunoprecipitation (MeDIP). We identified the high temperature induction-related differentially methylated regions (DMRs), and performed functional enrichment analysis for genes exhibiting DMR. These identified differentially methylated genes were potentially involved in the connection between environmental temperature and sex reversal in Nile tilapia. In this study, four samples (control females, CF; control males, CM; induced females, IF; induced males, IM) were analyzed.
