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.

Mapping active promoters by ChIP-seq profiling of H3K4me3 in cichlid fish - a first step to uncover cis-regulatory elements in ecological model teleosts

Project description:Evolutionary alterations to cis-regulatory sequences are likely to cause adaptive phenotypic complexity, through orchestrating changes in cellular proliferation, identity and communication. For non-model organisms with adaptive key-innovations, patterns of regulatory evolution have been predominantly limited to targeted sequence-based analyses. Chromatin-immunoprecipitation with high-throughput sequencing (ChIP-seq) is a technology that has only been used in genetic model systems and is a powerful experimental tool to screen for active cis-regulatory elements. Here, we show that it can also be used in ecological model systems and permits genome-wide functional exploration of cis-regulatory elements. As a proof of concept, we use ChIP-seq technology in adult fin tissue of the cichlid fish Oreochromis niloticus to map active promoter elements, as indicated by occupancy of trimethylated Histone H3 Lysine 4 (H3K4me3). The fact that cichlids are one of the most phenotypically diverse and species-rich families of vertebrates could make them a perfect model system for the further in-depth analysis of the evolution of transcriptional regulation. examination of H3K4me3 in adult fin tissue of the Nile tilapia (Oreochromis niloticus)

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.

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.

Fecal microbiota transplantation treatment maintains post antibiotics gut function by change the gut microbiome and fecal metabolome to reduce gut inflammation and oxidative stress in nile tilapia (Oreochromis niloticus)

Project description:The imbalance of intestinal flora can affect the immune function and structural integrity of the intestinal barrier, leading to the colonization and reproduction of opportunistic pathogenic bacteria in the intestine to become the dominant flora, eventually inducing enteritis. This study aimed to investigate whether fecal microbiota transplantation (FMT) could improve the gut barrier in Nile tilapia (Oreochromis niloticus). The experiment involved administering normal saline (NS group) and fecal microbiota (FMT group) (from the negative control group (C group)) to tilapia that had been treated with oxytetracycline hydrochloride (OTC) (M group) by gavage. A total of 300 male tilapia (mean body weight 596.65 ± 47.18 g) were used, with 180 of them being fed OTC (120 mg/kg body weight/day) for 7 days to induce intestinal oxidative stress, while the rest served as the control group. After confirmation of mild chronic enteritis, the tilapia were treated in different ways.

Uncovering novel roles for thyroid hormones in teleost fishes: Differential transcriptome regulation in brain and liver by 3,5-T2 and 3’,3,5-T3

Project description:We used a RNA-seq approach to determine the effect of 3,5-di-iodothyronine (T2) and 3,5,3'-tri-iodothyronine (T3) exogenous treatment on the transcriptome of tilapia (Oreochromis niloticus) liver, cerebellum, and thalamus-pituitary. We identified a total of 169, 154 and 2863 genes that were Thyroid hormone-regulated (FDR < 0.05) in tilapia cerebellum, thalamus-pituitary and liver, respectively. Among those, 130, 96 and 349 genes were uniquely regulated by T3, whereas 22, 40 and 929 were only regulated by T2 in the cerebellum, thalamus-pituitary and liver.
