Project description:Application of cisplatin (DDP) for treating lung cancer is restricted due to its toxicity and drug resistance. In this study, we aimed to examine whether Jinfukang (JFK), an effective herbal medicine against lung cancer, enhances DDP-induced cytotoxicity in lung cancer cells. Morphologically, we observed JFK increases DDP-induced pro-apoptosis in A549 cells in a synergistic manner. Transcriptome profiling analysis indicated that combination of JFK and DDP regulates genes involved in apoptosis-related signaling pathways. Moreover, we found the combination of JFK and DDP produces synergistic pro-apoptosis effect in other lung cancer cell lines NCI-H1975, NCI-H1650 and NCI-H2228. Particularly, we demonstrated AIFM2 is activated by the combined treatment of JFK and DDP, and partially mediate the synergistic pro-apoptosis effect. Collectively, this study gives the first evidence that activation of AIFM2 contributes to induction of pro-apoptosis by combined treatment with JFK and DDP in human lung cancer cells and provides an insight for its potential clinical application in lung cancer treatment.
Project description:Microarray studies was performed to analyze gene expression changes in NCI-H2347 cells after treatment with 50 µM pioglitazone for 12hr, 24hr and 48hrs. RNA samples, containing 3 replicates for each sample, were extracted from NCI-H2347 cells after treatment with pioglitazone or vhicle (DMSO) for 12hr, 24hr and 48hrs. After biotin labeling, samples were hybridized on the Illumina Human HT12v4.0 Expression Beadchip.
Project description:A time-course RNA-seq experiment testing the effect of drug treatment using selective CDK9 inhibitor AZD4573. The experiment was done using a pancreatic cancer cell line HPAF-II carrying KRAS G12D mutation.

Project description:We report RNAseq gene expression data following ARS-1620 treatment and shKRAS expressing cells (NCI-H358). We also compare gene expression changes following treatment with ARS-1620 or trametinib in NCI-H358, LU65 (KRAS-G12C+), and A549 (KRAS-G12S+) cells. Additionally we report a time course (4, 24, 48hr) of ARS-1620 and trametinib treated NCI-H358 cells.
Project description:Genome variation profiling of lung adenocarcinoma cells comparing untreated NCI-H1975 cells with CNX-2006-resistant untreated cells. Goal was to determine the potential mechanism of resistance to mutant EGFR-TKIs and rationally design novel strategies for the treatment of EGFR-mutant lung cancer patients. Two-condition experiment: NCI-H1975 parental cells vs CNX-2006-resistant cells. Pooled DNA from healthy volunteers was used as reference.
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.
