Transcriptomic Analysis of Zebrafish Immune Response Induced by Green Synthesis Zinc Oxide Nanoparticles using Propolis Extract

ABSTRACT: The present study aims to synthesize zinc oxide nanoparticles using propolis extract and evaluate its effect on zebrafish immune response following caudal fin amputation model on zebrafish (Danio rerio). The phytochemical composition of extract was identified using Gas Chromatography Mass Spectrometry (GC-MS). The synthesized Pro-ZnO NPs were characterized using UV-Vis spectrophotometer, Fourier transform infrared (FTIR) and transmission electron microscopy (TEM) analysis. The toxicity of Pro-ZnO NPs was evaluated in zebrafish larvae, with the LC50 values of 4 mg/L which classified as toxic. Male zebrafish (n = 5 per group, triplicate) underwent caudal fin amputation and were divided into two groups to assess their immunological response: a control group and a Pro-ZnO 2 mg/L treatment group for a duration of four days. Total RNA was extracted from the caudal fin blastema four days post-amputation (dpa), and subsequently subjected to strand-specific mRNA sequencing using Illumina Platform. The principal component analysis (PCA) yielded a clear delineation between the ZnO-treated group and the control group, thereby indicating a distinct grouping pattern.

Transcription profiling of zebrafish adult and larval fin to investigate mechanisms of regeneration

Project description:Zebrafish have the remarkable ability to regenerate body parts including the heart, spinal cord and fins by a process referred to as epimorphic regeneration. Recent studies have illustrated that similar to adult zebrafish, early life stage-larvae also possess the ability to regenerate the caudal fin. A comparative genomic analysis was used to determine the degree of conservation in gene expression among the regenerating adult caudal fin, adult heart and larval fin. Results indicate that these tissues respond to amputation/injury with strikingly similar genomic responses. Comparative analysis revealed raldh2, a rate-limiting enzyme for the synthesis of Retinoic acid (RA), as one of the highly induced genes across the three regeneration platforms. Experiment Overall Design: The caudal fin of zebrafish larvae at 2days post fertilization were amputated. Caudal fin tissue at 2dpf and regenerating fins were isolated at 1, 2and 3 days post amputation. Three replicates were collected at each time point. 150 fins were pooled to comprise one replicate.

Small RNA and mRNA expression profiling during zebrafish caudal fin regeneration

Project description:Previous studies of zebrafish caudal fin regeneration have shown that multiple genetic programs are moduled through regulatory factors. MicroRNAs are short highly conserved non-coding genes that suppress expression of target genes and thereby control multiple genetic programs. Given their important regulatory roles and evolutionary conservation, we hypothesize that microRNAs define a conserved genetic regulatory circuit important for appendage regeneration. We characterized microRNA expression during zebrafish caudal fin regeneration using small RNA sequencing. The stages of caudal fin regeneration were assayed for mRNA expression using mRNA sequencing. Small RNA and mRNA gene expression profiling during 0 and 4 days post amputation.

Zebrafish caudal fin amputation models the effects of diabetes on inflammation and regeneration

Project description:Aim: In this study, we aim to establish a diabetic zebrafish model and examine the effects of high glucose on inflammation and tissue regeneration. Materials and Methods: Tübingen strain zebrafish (wild type, WT), Tg (mpo: EGFP), and Tg (coro1a: EGFP) zebrafish were employed. Caudal fin amputation was performed to study tissue regeneration and inflammation. Results: Our results showed that high glucose increased the recruitment of neutrophils and macrophages after amputation. Most importantly, limb regeneration was severely impaired after amputation in zebrafish larvae exposed to 222 mM glucose for 14 days. In addition, inflammatory factors IL-1β, IL-6, TNF-α, VCAM-1, and MCP-1, which are closely related to the development of diabetic wound, increased significantly in caudal fin amputation after glucose exposure. The p38 inhibitor SB203580 can reduce the expression of inflammatory factors and promote regeneration in high glucose. It showed that caudal fin amputation after glucose exposure resulted in genes enrichment of several pathways involved in amino acid metabolism, lipid metabolism, and inflammation based on high-throughput transcriptome sequencing. Conclusions: Overall, this experimental system using zebrafish larvae provides a wide spectrum of genetic and molecular profile recapitulating human diabetes which will be beneficial for basic research of inflammation and regeneration in diabetic background and promote translational research for diabetes therapy.

Gene expression data from time course of fin regeneration in Danio rerio (part 1)

Project description:Olsen et al (2010) have shown that induced Diabetes mellitus (DM) in adult Zebrafish results in an impairment of tissue regeneration as monitored by caudal fin regeneration. In those studies, streptozocin was used to induce hyperglycemia in adult zebrafish, and then, following streptozocin withdrawal, a recovery phase was allowed to re-establish euglycemia, due to pancreatic b-cell regeneration. DM-associated impaired fin regeneration continued indefinitely in the metabolic memory state (MM); allowing for subsequent molecular analysis of the underlying mechanisms of MM. This study focuses on elucidating the molecular basis explaining DM-associated impaired fin regeneration and why it persists into the MM state. The analysis of microarray data indicated that of the 14,900 transcripts analyzed, aberrant expression of 71 genes relating to tissue developmental and regeneration processes were identified in DM fish and the aberrant expression of these 71 genes persisted into the MM state. Key regulatory genes of major signal transduction pathways were identified among this group of 71; and therefore, these findings provide a possible explanation for how hyperglycemia induces impaired fin regeneration and why it continues into the MM state. Total RNA was extracted from caudal fin at 0, 12, 24 and 48 hours post amputation from untreated controls and metabolic memory zebrafish.

Single-cell RNA sequencing of the cut and uncut caudal fin of zebrafish larvae

Project description:Purpose: The goal of this study was to establish the first detailed cell atlas of the regenerating caudal fin of zebrafish larvae. Intact and regenerating caudal fin were used for single-cell RNA-sequencing with the aim to provide the first integrated model of epimorphic regeneration in zebrafish larvae and demonstrate the diversity of the cells required for blastema formation. Methods: 150 of regenerating caudal fin (cut) and intact caudal fine (uncut) samples were dissociated and loaded into the 10x Genomics Chromium Platform, and sequenced using Illumina NovaSeq 6000. Conclusion: Our study constitutes a resource of the gene expression profile in intact and regenerating caudal fin of zebrafish larvae. We report the application of single-molecule-based sequencing technology for high-throughput profiling of both intact (uncut) and regenerating caudal fin samples (cut) at 24hpA. We confirmed the presence of macrophage subsets, previously described by our group to govern zebrafish fin regeneration, and identified a novel blastemal cell population.

Transcription profiling of Zebrafish 1 Day post amputation vehicle or beclomethasone exposed to study regeneration

Project description:Zebrafish caudal fin regeneration is an established model to study tissue regeneration. In order to identify novel molecular signaling pathways critical for regeneration, we developed a rapid throughput in vivo regeneration assay. We screened a 2000 member structurally diverse small molecule library, followed by assessment of regenerative progression at three days post amputation. A cluster of glucocorticoids was identified among the âpositive hitsâ. To identify the molecular targets of the activated glucocorticoid receptor, microarray analysis was performed using RNA isolated from the regenerates of control and glucocorticoid exposed zebrafish. We identified 673 transcripts that were differentially regulated. The level of expression and spatial expression pattern of select genes were completed by qPCR and by in situ hybridization, respectively. Altogether, these studies demonstrate the power of chemical genetics to identify chemical probes and their targets which will provide a path towards defining conserved regenerative pathways. Experiment Overall Design: The caudal fin of zebrafish larvae at 2days post fertilization were amputated and exposed to vehicle control alone or Beclomethasone . Regenerating fins were isolated at 1days post amputation. Three replicates were collected at each time point. 150 fins were pooled to comprise one replicate.
