Project description:To investigate the effect of shikonin on the proliferation and migration of lung cancer cells, we used shikonin treated with A549 and H1299 cells We then performed gene expression profiling using RNA-seq data from A549 cells.
Project description:To investigate the role of shikonin in the development of colon cancer, we treated HCT116 cells with shikonin for 24 hours We then used RNA-seq data from HCT116 cells for gene expression profiling
Project description:Aspergillus terreus is an emerging fungal pathogen in immunocompromised patients. Due to intrinsic resistance of AmB against A. terreus and acquiring resistance to azoles, alternative antifungal strategy needs investigation. Thus, we explored the activity of phytochemicals such as Shikonin, gallic acid, coumaric acid and quercetin against A. terreus. Amongst these, shikonin showed significant inhibition at MIC50;2 µg/ml, considered for proteome profiling.
Project description:We performed RNA-seq analysis using differnt breast cancer cell lines (MCF-7, SK-BR-3 and MDA-MB-231) after shikonin treatment. We reported that shikonin enhances the expression of DUSP-1 and DUSP-2. Shikonin induces apoptosis and decreases the phosphorylation of JNK1/2 through activationg DUSP-1 and DUSP2.
Project description:We investigate and define here the in vivo biological effects of shikonin, at the transcriptome and microRNA levels, in mouse skin tissues. Through cross-examination between total RNA transcripts and microRNA data sets, we predicted that shikonin treatment may affect the epithelial–mesenchymal transition (EMT) process and the expression of related microRNAs, including 200a, 200b, 200c, 141, 205 and 429 microRNAs, in test skin tissue. Indeed, further in vivo tests on mouse abdominal skin tissue confirmed the stimulatory effect of shikonin on regulatory molecules of the EMT process in epidermal tissue. In addition, RT-PCR analyses confirmed the downregulating effects of shikonin on the expression of microRNA 205 and members of the microRNA 200 family, which are known to be involved in the EMT process. Gene expression of two RNA targets of the microRNA 200 family in EMT regulation, namely Sip1 (Zeb2) and Tcf8 (Zeb1), were consistently upregulated by shikonin treatment. We demonstrate here that shikonin can confer a potent stimulatory effect on the EMT process and suppress the associated-microRNAs expression in vivo in skin tissues.

In order to systematically evaluate the effects of shikonin on mouse skin tissues, we next compared the gene expression profiles in shikonin-treated and acetone-treated skin tissues at different time points. Total RNA samples were collected at indicated time points for transcriptome and microRNA array analyses.
