Insights into Molecular Mechanisms and Therapeutic Potential of Arborvitae Essential Oil (Thuja plicata) on Cervical Cancer Cells

ABSTRACT: This analysis aimed to assess the effect of arborvitae (Thuja plicata) essential oil (AEO) in an in vitro model of cell lines derived from cervical cancer, namely HeLa and SiHa, by examining its influence on gene expression modulation. The working cell lines were HeLa, and SiHa. Total RNA sequencing was performed on the Illumina NovaSeq 6000 platform by Novogene Bioinformatics Technology Co., Ltd, Beijing, China, with two independent replicate sequences for each cell model. Methodology: The execution of the bioinformatics pipeline analysis was carried out as follow: R (ver. 4.3.1), RStudio (ver. 2023.09.1 +494) and Galaxy (https://www.usegalaxy.orgaccessed on 02 February 2024) open-source platforms were used to analyze the Illumina raw data. The Quality Check was conducted through the FastQC tool (v0.74+galaxy0). Afterward, all the reads were processed by the Rsubread package (v2.14.2); at that point, the reads were trimmed and aligned to the Human Genome Reference (GRCh38.p14 v44). The obtained output was the BAM files, of which the number of reads was counted by the FeatureCounts tool (v2.0.3); at the final step, the Differential Expression Analysis was settled by the DESeq2 package for R (ver. 1.42. 0). The differential gene expression measurements were normalized by DESeq2's median of ratios (median of ratio of gene counts relative to geometric mean per gene) method. All genes with an adjusted p-value (p-adj) minus or equal to 0.05 and fold change (Log2FC) up to 2 or less than minus 2 were selected as differentially expressed genes (DEGs). Conclusions: Our study found that AEO regulates genes related with cell cycle regulation, cell growth, differentiation, and cell death in both cell lines, mainly through downregulation; however, its effect appears to be mediated by different pathways in each cell line.

Project description:Purpose: We identified novel methyl reader domain protein in P. falciparum. Using Next Generation Sequencing, we studied the differential gene expression in PfCDP conditionally deleted P. falciparum versus wild type. Methods: Transcriptome analysis of PfCDP KO vs WT P. falciparum using high throughput RNA sequencing in triplicate (Three controls and three KO samples). The total RNA was isolated from P. falciparum WT and PfCDP KO lines, the quality of RNA was assessed using Nanodrop2000, and Bioanalyzer 2100. RNA sequencing libraries were prepared with Illumina-compatible NEBNext® Ultra™ II Directional RNA Library Prep Kit. The double stranded cDNA was purified using JetSeq Beads and the purified cDNA was end-repaired, adenylated and ligated to Illumina multiplex barcode adapters as per NEBNext® Ultra™ II Directional RNA Library Prep protocol. The libraries were sequenced on IlluminaHiSeq 4000 sequencer for 150 bp paired-end chemistry. The data obtained from the sequencing run was de-multiplexed using Bcl2fastq software v2.20 and FastQ files were generated based on the unique dual barcode sequences. The sequencing quality was assessed using the FastQC software ver. 0.11.9. The adaptor sequences and low quality bases (phred quality cutoff set at 30) were trimmed from the reads using the Trim Galore tool ver. 0.6.5. The reads that survived quality check were aligned to the Plasmodium falciparum 3D7 isolate genome (ver. 46) using the Hisat2 read alignment tool. The library strandedness was set as firststrand in accordance with the strand specific library preparation protocol. The alignement output files in the sam format were sorted and converted to the bam format using the Samtools utilities (ver 1.10). Results: The transcript abundance count data was generated using the HTSeq-count function (ver. 0.12.4). Differential gene expression analysis was performed using the DESeq2 package (ver. 3.11) in R programming environment. Genes were classified as deregulated on the basis of log2fold-change cutoff of +1 (for upregulation) and -1 (for downregulation) and p-value cutoff of 0.05. Gene Ontology analysis was performed using the GO tool hosted by the PlasmoDB web database. Data visualisation of the DGE was performed using custom scripts in R programming environment and with DESeq2 package utilities. The DGE analysis has revealed that up regulation of a subsets virulence genes family with significant p values. Conclusions: Our study represents the first detailed analysis of retinal transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.
