Project description:To investigate the impact of sorafenib treatment on gene expression in Treg cells, we performed RNA sequencing on Treg cells treated with sorafenib and on control Treg cells that were not treated with sorafenib. Specifically, our study focused on the expression of immune-suppressive related genes, and we observed an upregulation in the expression of Tgf-β1 (Transforming Growth Factor-β1), Prf1 (Perforin 1), Gzma (Granzyme A), and Il10 (Interleukin 10).

Project description:Sorafenib is associated with cardiac adverse effects, including left ventricular dysfunction. However, the precise mechanism remains unclear. Here, we aimed to establish the genes responsible for this cardiotoxicity using zebrafish. A pigmentless zebrafish line expressing green fluorescent protein in the heart were treated with or without sorafenib. In vivo fluorescent cardiac imaging revealed that the ventricular dimension of the longitudinal axis in zebrafish treated with sorafenib was significantly lower than in those without sorafenib. Transcriptome analysis of zebrafish hearts revealed that expression of stanniocalcin1 (stc1) in zebrafish treated with sorafenib was significantly lower than that without sorafenib treatment. We were able to demonstrate that the ventricular dimension of the longitudinal axis in stc1 morphant was significantly smaller than that of control zebrafish and that forced expression of stc1 normalized the decrease in ventricular diameter in stc1 morphant and zebrafish treated with sorafenib. These data suggest that stc1 is the gene responsible for sorafenib-induced cardiotoxicity.

Four independent experiments were performed for each group.

Project description:Sorafenib resistance up-regulated circRNA_104797 could be transmitted by exosomes and responsible for the spread of Sorafenib resistance among HCC cells. CircRNA_104797 was critical for Sorafenib resistance maintenance and silencing circRNA_104797 could substantially increase the efficacy of Sorafenib by inducing apoptosis. Mechanism dissection unveiled that circRNA_104797 could specifically sponge miR-103a-2-5p and miR-660-3p and act as a competing endogenous RNA (ceRNA), thus competitively activated wnt/β-catenin pathway and induced Sorafenib resistance. Meanwhile, LC-MS/MS also revealed that circRNA_104797 could specifically bind to translation related proteins, which might regulate downstream glycan biosynthesis and lipid metabolism, and finally induce Sorafenib resistance. In vivo experiments portrayed a promising clinical application by locally injection of in vivo-grade siRNA for circRNA_104797 by TACE or other manners, which could intensively enhance Sorafenib efficacy in HCC patients. The clinical application of in vivo-grade siRNA for circRNA_104797 in Sorafenib treated HCC patients might shed bright future for the management of advanced HCC.

Project description:OBJECTIVE: Sorafenib is effective in hepatocellular carcinoma (HCC), but patients ultimately present disease progression. Molecular mechanisms underlying acquired resistance are still unknown. Herein, we characterize the role of tumor-initiating cells (T-ICs) and signaling pathways involved in sorafenib resistance. DESIGN: HCC xenograft mice treated with sorafenib (n=22) were explored for responsiveness (n=5) and acquired resistance (n=17). Mechanism of acquired resistance were assessed by: 1) Role of T-ICs by in vitro sphere formation and in vivo tumorigenesis assays using NOD/SCID mice, 2) Activation of alternative signaling pathways and 3) Efficacy of anti-FGF and anti-IGF drugs in experimental models. Gene expression (microarray, qRT-PCR) and protein analyses (immunohistochemistry, western blot) were conducted. A novel gene signature of sorafenib resistance was generated and tested in 2 independent cohorts. RESULTS: Sorafenib-acquired resistance tumors showed significant enrichment of T-ICs (164 cells needed to create a tumor) vs. sorafenib-sensitive tumors (13400 cells) and non-treated tumors (1292 cells), p<0.001. Tumors with sorafenib-acquired resistance were enriched with IGF and FGF signaling cascades (FDR<0.05). In vitro, cells derived from sorafenib-acquired resistant tumors and two sorafenib-resistant HCC cell lines were responsive to IGF or FGF inhibition. In vivo, FGF blockade delayed tumor growth and improved survival in sorafenib-resistant tumors. A sorafenib-resistance 175-gene signature was characterized by enrichment of progenitor-cell features, aggressive tumoral traits and predicted poor survival in 2 cohorts (n=442 HCC patients). CONCLUSION: Acquired resistance to sorafenib is driven by tumor initiating cells with enrichment of progenitor markers and activation of IGF and FGF signaling. Inhibition of these pathways would benefit a subset of patients after sorafenib progression. Transcriptomic profile of subcutaneous Huh7 cells-derived tumors treated with sorafenib that developed acquired resistance to the drug (n=4), remain responsive to sorafenib (n=3) or were treated with brivanib after development of resistance (n=3). Gene profiling of hepatospheres generated from tumors with acquired resistance to sorafenib (n=3) and non-treated tumors (n=3) was also analyzed.

Project description:The aim of the study is to analyse whether the Sorafenib renders FLT3-ITD-positive acute myeloid leukemia (AML) cells more immunogenic . We used Ba/F3-ITD cells as a model cell line to study the effect of Sorafenib on FLT3-ITD-positive AML cells. Ba/F3-ITD cells are murine pro-B cell lines with a stable FLT3-ITD expression. Ba/F3-ITD cells were treated with DMSO or 10nM sorafenib for 24 hours. Cells were harvested and total RNA was isolated
