Next-generation sequencing quantitative analysis of the transcriptome of intrahepatic cholangiocarcinoma cell line treated with or without anlotinib.

To examine the potential mechanism of anlotinib to inhibit intrahepatic cholangiocarcinoma, we used RNA-seq to analyze the effect of anlotinib treatment on the transcriptome changes of intrahepatic cholangiocarcinoma cell lines HCCC9810 and RBE. HCCC9810 and RBE cells were treated with DMSO or anlotinib at 5 μM for 24 hours, and then subjected to total RNA isolation and deep sequencing. We used Venn diagrams of RNA-seq results of HCCC9810 and RBE cells treated with anlotinib to indicate genes that were up- or down-regulated (adjusted P value <0.05, fold = 2.0). There are 420 genes in both groups (Figure 4A, 273 genes up-regulated and 147 genes down-regulated). In summary, the above sequencing results were analyzed by bioinformatics, and it was concluded that by inactivating the VEGF / PI3K / AKT signaling pathway and through cell cycle arrest, anlotinib treatment inhibited the proliferation and invasion of tumor cells and promoted Apoptosis. Intrahepatic cholangiocarcinoma cell lines (HCCC9810, RBE) in two groups were examined for changes in transcriptomics at anlotinib (24 hours after 5 μM concentration treatment). There were three biological replicates in each group.，3 treatment vs 3 control
