Chromatin accessibility analysis uncovers TFAP2A as a regulator on pro-angiogenesis of acquired resistance to anlotinib

ABSTRACT: Anlotinib, a multitarget agent a multi-target agent that inhibits tumor proliferation and angiogenesis, has been demonstrated to be effective for non-small cell lung cancer (NSCLC) at third-line or over third-line. However, the underlying mechanisms of anlotinib acquired-resistance is still unclear. Here we performed chromatin accessibility profiling on anlotinib-resistant NCI-H1975 and wild-type NCI-H1975. By integrating with transcriptome analysis, we found that anlotinib resistance was due to increased angiogenic capacity, and revealed that TFAP2A was involved in anlotinib resistance. Next, TFAP2A was knock-down in anlotinib-resistant cells and RNAseq was performed to see down-regulated genes with TFAP2A KD.

Role of Anlotinib-induced CCL2 decrease in anti-angiogensis and response prediction for Non-Small Cell Lung Cancer therapy

Project description:Purpose: Our previous clinical trials have been demonstrated that Anlotinib can inhibit tumor growth upon refractory advanced non-small cell lung cancer (NSCLC) patients with the possibility mechanism of anti-angiogenesis. The present study sought to reveal the underlying molecular mechanism of Anlotinib-induced anti-angiogenesis in advanced NSCLC. Experimental Design: Computed tomography (CT) was used to evaluate the treatment effect of Anlotinib upon refractory advanced NSCLC patients. Transcriptome profiling was performed to identify the key gene expression alteration in NCI-H1975 cells before and after Anlotinib treatment. NCI-H1975 derived xenograft model was applied to investigate treatment effect and verify anti-angiogenesis mechanism of Anlotinib. Results: Anlotinib induces tumor cytotoxicity on refractory advanced NSCLC patients, NCI-H1975 derived xenograft models and lung adenocarcinoma cell lines. Transcriptome profiling revealed CCL2 blockade could be responsible for Anlotinib-induced anti-angiogenesis. NCI-H1975 derived xenograft model demonstrated Anlotinib-induced CCL2 blockade play an important role in anti-angiogenesis. Conclusions: This study not only offered the first evidence that Anlotinib inhibits angiogenesis via blocking CCL2 expression, but also provided a novel theoretical basis for the application of Anlotinib in advanced NSCLC patients.

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

Project description: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.

Project description:Osimertinib, a third-generation EGFR-TKI, has applied to non-small cell lung cancer harboring activated EGFR mutation with or without T790M. However, the appearance of tumors resistant to osimertinib has been reported. We established and characterized osimertinib-resistant cells derived from NCI-H1975 cells harboring activating EGFR and T790M mutation.
