Microarray analysis of T-cell death-associated gene 8 (TDAG8)-mediated gene expression in mouse Lewis lung carcinoma (LLC) cells.

ABSTRACT: We previously identified an extracellular pH-sensing G protein-coupled receptor T cell death associated gene 8 (TDAG8) as an extracellular pH sensor of tumor cells that promotes cell growth/survival in vitro and tumor development in vivo. To determine genes regulated by TDAG8 in vitro, mouse Lewis lung carcinoma (LLC) cells stably expressing TDAG8 (TDAG8-LLC cells) and control vector (control LLC cells) were cultured under acidic conditions. Transcriptome microarray analysis using Affymetrix GeneChip Mouse Genome 430 2.0 Arrays was performed with total RNA prepared from these cells.

Gene expression profiling of mature dendritic cells from mice s. c. treated with GM-CSF-gene transduced LLC cells (LLC/SeV/GM) or control cells (LLC, LLC/SeV/GFP)

Project description:Irradiated granulocyte macrophage-colony stimulating factor (GM-CSF)-transduced autologous tumor cells induce substantial antitumor immunity through the maturation and migration of dendritic cells (DCs). However, little is known about the key molecules involved in GM-CSF-sensitized DCs (GM-DCs) in tumor draining lymph nodes (TDLNs). We initially confirmed that mice subcutaneously injected with poorly immunogenic syngeneic Lewis lung carcinoma (LLC) cells transduced with Sendai virus encoding GM-CSF (LLC/SeV/GM) significantly rejected the tumor growth. Using microarray expression profiling, we obtained a large number of gene expression data files from GM-DCs and control DCs in TDLNs, and subjected them to network-based cluster analysis and unexpectedly unraveled the expression levels of type I IFNs-related genes specifically expressed in plasmacytoid DCs (pDC) were robustly up-regulated in GM-DCs. In vivo depletion assay showed that pDC-depleted mice treated with subcutaneous LLC/SeV/GM cells abrogated the antitumor effects observed in control mice. Moreover combination use of imiquimod for TLR7 triggering on pDC with irradiated LLC/SeV/GM cells induced a significant therapeutic antitumor effect with marked induction of CD9+ pDC with antitumor phenotype, whereas other control mice groups had only minimal to-modest antitumor responses, implicating that this combined vaccine strategy using imiquimod could be promising for improvement of GM-CSF-induced antitumor immunity. Mouse GM-CSF induced gene expression in mature dendritic cells in tumor draining lymph nodes from C57/BL6N female mouse was measured at 2 days after s.c. tumor challenge with GM-CSF gene-transduced LLC cells (LLC/SeV/GM) or control cells (LLC, LLC/SeV/GFP).

Lewis lung carcinoma cells and TDAG8 overexpression

Project description:We observed the effects of TDAG8-overexpression in Lewis lung carcinoma (LLC) cells on the gene expression pattern. TDAG8-overexpressing or vector-transfected control LLC cells (5 × e5 in 200 µL of HBSS) were injected into the lateral tail veins of 6–8-week-old C57BL/6 mice. Lungs were removed on day 19 post-injection, and total RNA was extracted.

Expression data from the subclones of Lewis Lung Carcinoma (LLC) cells

Project description:Medium conditioned by LLC cells stimulates thermogenic gene expression when added onto primary adipocytes. We generated single cell colonies from parental LLC cells. Media conditioned by the subclones stimulated thermogenic gene expression in primary adipocytes at varying degrees. Subclones 2, 3, 6 and 28 produce significantly larger amount of thermogenic activity than the subclones 18, 19, 23 and 24. We compared gene expression profiles of these subclones to identify secreted factors enriched in the more thermogenic clones. LLC subclones were cultured under conditioned medium preparation conditiones and total RNA was extracted from biological replicates.

Transcriptomic computational analysis of mastic oil-treated Lewis lung carcinomas

Project description:Mastic oil from Pistacia lentiscus variation chia, a blend of bioactive terpenes with recognized medicinal properties, has been recently shown to exert anti-tumor activity. Lewis lung carcinoma (LLC) cells are mastic oil-susceptible cells and were used in this work to study the effects of mastic oil at the transcriptomic level.

Project description:Purpose: To study the alteration of whole transcriptome of Lewis lung carcinoma (LLC) cells after the decreasing of malignant properties of tumor by treatment of tumor-bearing mice with RNase A. Methods: Whole transcriptome profile of Lewis lung carcinoma before and after RNase A treatment were generated by deep sequencing using SOLiD 5.5. The sequence reads were mapped by Bioscope 1.3 software, differential expression was evaluated by Cufflinks v.2.0.1 package. Results: Difference in expression was found for 966 genes. Conclusions: Our study represents the first detailed analysis of alteration of transcriptome of Lewis lung carcinoma after the decrease of malignant prtoperties of the tumor (proliferation and invasion) by RNase A.
