Differential gene expression in SN12C.19 renal cells with insertion of the chromosomal 3p arm

ABSTRACT: SN12C.19 is a renal carcinoma cell line with loss of heterozygosity in the 3p chromosomal region near the centromere. It is believed that a tumor suppressor gene is located in this region. In studies with athymic nude mice, tumor formation followed injection of SN12C.19 cells. Tumor formation did not follow by injection of the hybrid cell line SN19(3i)YY, which includes a very small fragment insertion of the 3p chromosomal arm. The goal of this array experiment was to identify genes differentially expressed in SN12C.19 by the introduction of a normal copy of the chromosomal 3p arm. SN12C.19 and SN19(3i)YY cells were hybridized to Affymetrix U133 Plus 2.0 Chips. Array quality was inspected with output from dChip software. Gene expression was quantified with PDNN software. There were 57 probesets showing differential expression on the 3p arm, corresponding to 46 genes. A suppression subtractive hybridization (SSH) library was previously constructed using as starting materials microcell hybrid clones which mapped the NRC-1 locus and containing defined fragments of chromosome 3p12 which were either suppressed or unsuppressed for tumorigencity following injection of microcell hybrid clones into athymic nude mice

Project description:Two miRNA arms from the same precursor, miR-574-5p and miR-574-3p, were reversely expressed and played exact opposite role in gastric cancer progression. miR-574-5p/-3p ratio was also strongly correlated with higher TNM stages and shorter survival of patients. The increase of miR-574-5p/-3p ratio, or the arm-imbalance of miR-574 was due to the dynamic expression of their highly complementary targets in gastric carcinogenesis. The arm imbalance of miR-574 in turn strongly contributed to and further promoted gastric cancer progression. Conclusion: Our findings indicated that targets mediated miR-574 arm-imbalance contributed to gastric cancer progression. Re-modification of the miR-574-targets homeostasis may represent a realistic approach for gastric cancer prevention and therapy.

Project description:Mammalian target of rapamycin (mTOR) is a serine/threonine kinase involved in multiple intracellular signaling pathways promoting tumor growth. mTOR is aberrantly activated in a significant portion of breast cancers and is a promising target for treatment. Rapamycin and its analogues are in clinical trials for breast cancer treatment. Patterns of gene expression (metagenes) may also be used to simulate a biologic process of effects of a drug treatment. In this study, we tested the hypothesis that the gene-expression signature regulated by rapamycin could predict disease outcome for patients with breast cancer. Results: Colony formation and sulforhodamine B (IC50 < 1nM) assays, and xenograft animals showed that MDA-MB-468 cells were sensitive to treatment with rapamycin. The comparison of in vitro and in vivo gene expression data identified a signature, termed rapamycin metagene index (RMI), of 31 genes upregulated by rapamycin treatment in vitro as well as in vivo (false discovery rate of 10%). In the Miller dataset, RMI was significantly associated with tumor size or lymph node status. High (>75) percentile) RMI was significantly associated with longer survival (P = 0.015). On multivariate analysis, RMI (P = 0.029), tumor size (P = 0.015) and lymph node status (P = 0.01) were prognostic. In van 't Veer study, RMI was not associated with the time to develop distant metastasis (P = 0.41). In Wang dataset, RMI predicted time to disease relapse (P = 0.09). Conclusions: Rapamycin-regulated gene expression signature predicts clinical outcome in breast cancer. This supports the central role of mTOR signaling in breast cancer biology and provides further impetus to pursue mTOR-targeted therapies for breast cancer treatment. Mol Cancer. 2009 Sep 24;8(1):75. Experiment Overall Design: Rapamycin treatment of MDA-MB-468 breast cancer cell line: Experiment Overall Design: MDA-MB-468 cell line was treated by DMSO (vehicle) and 100 nM rapamycin for 24 hours. We sought to identify differentially expressed genes. Experiment Overall Design: Rapamycin treatment of breast tumor xenografts: Experiment Overall Design: MDA-MB-468 cells were inoculated in the mammary fat pad of female nude mice. When resulting tumor volumes had reached 75-150 mm3, the mice were divided in four groups. Groups 1 and 2 received a single injection of DMSO (vehicle) or rapamycin (15 mg/kg) intraperitoneally and sacrificied 24 h later (1-day groups). Groups 3 and 4 received weekly injections of DMSO or rapamycin for 3 weeks and sacrificied 24 h after the last injection (22-day groups).
