Safety and Efficacy of Anlotinib in Combination With Irinotecan in Patients With Pretreated Advanced Colorectal Cancer

Project description:Patients with pretreated advanced colorectal cancer are recruited to the phase I portion of this prospective non-randomised study in an escalated dose cohort. The primary endpoint of the dose-escalation phase is to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of anlotinib when given in combination with irinotecan. The phase II (dose-expansion) portion is designed to characterize the safety and potential efficacy of the combination therapy in pretreated advanced colorectal cancer patients.

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.

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

Project description: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.

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.

Enhancing Tumor Targeting of Antitumor Drugs through Anlotinib-Mediated Modulation of Extracellular Matrix and RhoA/ROCK Signaling Pathway

Project description:In this study, our research focused on investigating the impact of Anlotinib in enhancing the tumor targeting of antitumor drugs in vivo. Through RNA-sequencing and Label-free quantitative proteomics analysis, we discovered that Anlotinib effectively regulated the expression of extracellular matrix (ECM) genes and proteins, leading to a significant reduction in ECM stiffness. Our bioinformatic analysis indicated a potential positive relationship between the ECM pathways and gefitinib resistance, poor PD-1 treatment outcomes, as well as unfavorable prognosis in lung cancer patients following chemotherapy. To evaluate the efficacy of Anlotinib, we administered it in combination with anti-PD-1/PD-L1 agents, chemotherapeutic drugs, and gefitinib, and visualized their distribution using fluorescent labeling in various tumor types. Notably, our results demonstrated that Anlotinib substantially improved the drug targeting process by prolonging the retention time of antitumor drugs at the tumor site. Moreover, the combination therapy induced a notable loosening of the tumor tissue structure compared to the control group. This reduction in stiffness was further associated with decreased interstitial fluid pressures and tumor solid pressure. Additionally, we observed that Anlotinib effectively suppressed the RhoA/ROCK signaling pathway, inhibiting the formation of stress fibers. These findings strongly suggest that Anlotinib enhances the distribution and retention of antitumor drugs in tumors by modulating ECM expression and physical properties through the RhoA/ROCK signaling pathway. These valuable insights contribute to the development of combination therapies aimed at improving tumor targeting in cancer treatment.

miRNA expression profiles of erythroid cells following hydroxyurea treatment for sickle cell anemia

Project description:We hypothesized that miRNA regulation may be invloved in hydroxyurea-mediated fetal hemoglobin induction. Microarray analysis was utilized as an initial screening tool to determine differential miRNA expression in CD71+ erythroid cells comparing cells from control individuals without sickle cell anemia to patients with sickle cell anemia prior to treatment with hydroxyurea and patients receiving the maximum tolerated dose (MTD) of hydroxurea. CD71+ cells were isolated from whole blood of control individuals (n=2), pediatric patients without hydroxyurea treatment (n=3) and pediatric patients at hydroxyurea MTD (n=3). All 8 samples were analyzed for miRNA expression.
