Radiation-induced amphiregulin drives tumor metastases

Project description:In this study, we demonstrate that radiation induces the epidermal growth factor receptor (EGFR) ligand amphiregulin (AREG) in tumor cells, which stimulates distant metastasis proliferation in both patients and pre-clinical murine tumor models. Using single-cell RNAseq (sc-RNAseq), we characterized the effects of AREG-induction on immune cells in the lung metastatic microenvironment of B6 mice.

Increased microalgae Chlorella sorokiniana lipid yield induced by low-dose ionizing radiation

Project description:We demonstrate that low-dose ionizing radiation from X-rays drives metabolic activation in microalgae. We exploited this phenomenon to develop a method for increased lipid yield in stationary phase Chlorella sorokiniana cultures by 25% in just 24 hours, caused by a reproducible metabolic response that includes up-regulation of >30 lipid metabolism genes. This approach avoids the need to modify the strain or cultivation conditions, and does not affect cell viability or biomass.

Association of microRNAs with colon tumor metastases

Project description:We compared the expression of microRNAs in primary colon tumors with their paired liver metastases using the Nanostring human microRNA assays version 1 23 microRNAs were found to be differentially expressed between colon primary tumors and their paired metastases Total mRNA was extracted from flash frozen primary colon tumors and paired metastases. 18 tissues from 9 donors were used for this study. 100 ng of RNA was hybridized to Nanostring Human 0microRNA assays version 1.0. Data was normalized according to manufacterer's recommendation. This included background substraction and normalizing to the geometric mean of the highest 75 microRNAs.

caArray_green-00030: 2-methoxyestradiol (2ME2) induces mammary gland differentiation through amphiregulin-EGFR mediated signaling

Project description:2-methoxyestradiol (2ME2) induces mammary gland differentiation through amphiregulin-EGFR mediated signaling: molecular distinctions from the mammary gland of pregnant mice.High levels of 2ME2 are observed in the late stages of pregnancy. We investigated the role of 2ME2 on normal mammary gland development. Large scale gene expression assays were performed using Affymetrix GeneChips in pursuit of detailed molecular basis. (1) Mammary glands of wild type FVB mice administered 75 or 150 mg/kg of 2ME2 (2) Mammary glands of normal FVB/Nj mice (i) at day 16 of pregnancy, (ii) day 2 of lactation (iii) day 30 of post-lactation, and (3) mammary epithelial SCp2 cells after 6, 24 and 48 hours of 10 micromol 2ME2 treatment were examined. In vivo studies revealed that 2ME2 treatment up regulates the expression of amphiregulin. The clue to the role of 2ME2 in differentiation comes from studies in vitro which detected down regulation of inhibitor of differentiation (Id-1) gene and consequent up regulation of amphiregulin. The differentiation of E2 negative SCp2 cells by 2ME2 indicate estradiol independent mechanism.

Radiation-induced gene translation profiles reveal tumor type and cancer specific components

Project description:The goal of this study was to compare the radiation-induced gene translation profiles generated from human tumor cell lines that are treated with radiation. Keywords: stimulus or stress design A panel of cell lines included 5 gliomas, 4 pancreatic carcinomas, 3 breast carcinomas and 2 non-small cell lung carcinomas. In addition, radiation-induced gene translation profiles were generated for 4 normal human cell lines: a skin fibroblast (BJ), 2 lung fibroblasts (MRC5, MRC9) and mammary epithelial (MEC). Specifically, cell lines were exposed to 2 Gy or sham irradiated, polysome-bound RNA was isolated 6h later and subjected to microarray analyses. Each cell line was evaluated in biological replicates.
