Cadmium sulfide nanoparticles (CdSNPs) modulate key oncogenic pathways in PA1 ovarian cancer cells: Insights from...

Transcriptomics has become a useful tool for comparing the levels of gene expression in healthy and malignant cells, holding potential for the discovery of new cancer therapies. This study used RNA-sequencing and transcriptome analysis on the PA1 ovarian cancer cell line to examine the potential of Cadmium Sulfide Nanoparticles (CdSNPs) as a therapeutic agent. A total of 5.42 Gb of high-quality reads was estimated based on the findings of gene expression techniques, comprising 2.25 Gb of treated PA1 cells and 3.17 Gb of control cells. Of these, 1641 genes with padj<0.001 and log2 foldchange >2 were found to be significantly regulated DEGs (differentially expressed genes). Analysis of gene ontology (GO) assays demonstrates the molecular mechanism behind CdSNPs anticancer effects. GO:0006915, GO:0012501, GO:1903561, and GO:0070588 are a few significant highlights of elevated GO (enriched DEGs) that are involved in apoptotic pathways, extracellular vesicles, programmed cell death, and Ca++ signaling. KEGG analysis elucidated that up and downregulated DEGs were enriched in a few pathways: calcium signaling pathway, Apoptosis, and TNF signaling pathway. Important pathways like MAP kinase, JAK/STAT, cAMP, and folate biosynthesis, showed inhibitory effects on ovarian cancer cell proliferation. The results of this work provide insight into possible therapeutic approaches employing CdSNPs and encourage additional research using a variety of cell lines and in vivo models to improve ovarian cancer treatment.
