Differentially expressed genes analysis of wild type K562 cells treated with vandetanib and control (DMSO)

ABSTRACT: Purpose: The aim of this study was to evaluate the difference of mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO) by high-throughput sequencing results. Methods: Total RNA was extracted using the RNAfast200 kit according to the manufacturer’s protocol. Then, 200 ng RNA was sequenced with high throughput, and then pathway and GO analysis were used for comprehensive analysis. Finally, RT-PCR method was used to validate in large sample population. Results: High-throughput sequencing results showed that there were significant differences in mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO). Conclusions: It is the first time that we have used high-throughput sequencing to study the difference of mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO). The results of sequencing show that the expression of mRNA and lncRNA is quite different in K562 cells treated with vandetanib (1.56 μM) and control (DMSO).

Project description:Baicalein, a purified flavonoid compound with defined chemical structure extracted from the dry roots of Scutellaria radix that is a broadly used herb in China, has been proved to possess significant anti-hepatoma activity by inhibiting cell proliferation, invasion, metastasis and inducing apoptosis, autophagy via several cancer-related signaling molecules. In recent years, emerging studies have demonstrated that Chinese medicinal herbs can exert their anti-tumor effects through targeting lncRNAs，such as curcumin, camptothecin, resveratrol，paclitaxel. However, there is still no related report about the effects of baicalein on lncRNA expression profile when it exerts its inhibition on hepatoma tumor growth. To investigate whether the antitumor effect of baicalein is related to its modulation of lncRNA expression in hepatocellular carcinoma (HCC), we profiled the lncRNA expression in HCC cell line Bel-7402 treated with baicalein (0, 40, 80μM) for 24 hours using lncRNA microarray and detected the changes by comparing the lncRNA expression profile of HCC cell line Bel-7402 treated with baicalein (40 and 80 μM) and its DMSO control (0 μM). These findings suggest that modulation of lncRNA expression may be an important mechanism underlying the anti-hepatoma effects of baicalein and lay the groundwork for further investigations.
