Project description:Chinese lung adenocarcinoma cancer cells (SPC-A-1) and human larger cell lung cancer cells (NCI-H460) were injected into left cardiac ventricle of nude mice for bone metastases model, respectively. Bone metastatic lesions were detected by bone scintigraphy with 99mTc-methylene diphophonate, removed bone metastatic lesions for cell primary culture, chromosome analysis for determine the bone metastatic cells have a characterization of unchanged humanization, in the anesthesia death mice. Through eight in vivo ~ in vitro selections, the 4th, 8th generation cells of SPC-A-1, 8th generation cells of NCI-H460 and their parental cells were used for microarray analysis, respectively. Bone metastatic clones 4th and/or 8th generation SPC-A-1 vs. SPC-A-1, 8th generation NCI-H460 vs. NCI-H460, respectively. Biological replicates: one replicate for every group, independently grown and harvested. One replicate per array.
Project description:Widespread metastasis is the major cause of human lung cancer-related deaths, but there is much to be elucidated about underlying mechanism. Based on the genome-wide expression analysis of the highly metastatic lung cancer cell line NCI-H460-LNM35 (LNM35), we identified a cancer metastasis signature composed of 45 genes with previously uncharacterized features but well-known associations with human cancers including CXCL1, IER3, PTTG1, DAD1, METAP2, E-cadherin and galectin 3. In addition, the 45-gene metastasis signature gene set was significantly associated with a subset of primary tumors with poor prognosis not only in the lung but also the breast. Keywords: cell-line morphologic comparison
Project description:Human lung adenocarcinoma cell lines (CPA-Yang1, CPA-Yang2, CPA-Yang3, SPC-A-1) and human larger cell lung cancer cell line NCI-H460 were injected into left cardiac ventricle of nude mice for bone metastases clone, respectively. Bone metastatic lesions were detected by bone scintigraphy with 99mTc-methylene diphophonate and X ray. Removed bone metastatic lesions for cell primary culture, chromosome analysis for determine the bone metastatic cells have a characterization of unchanged humanization, in the anesthesia death mice. Through in vivo ~ in vitro selections, the bone-seeking clones 1st, 3th, 4th, 8th, 8th passage cells of CPA-Yang1, CPA-Yang2, CPA-Yang3, SPC-A-1, NCI-H460 and their parent cells were used for microarray analysis, respectively.
