Micrometastasis primary tumors

ABSTRACT: Primary tumors from a series of breast cancer patients evaluated for the presence of tumor cells in bone marrow. Samples were taken at primary surgery, RNA isolated from fresh frozen tumors, amplified and hybridized to 42k cDNA arrays. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc.

Cell division cycle in a human cancer cell line (HeLa)

Project description:This experiment set contains the complete set of raw data for Whitfield et al. (2002)Mol.Biol.Cell. HeLa S3 cells were synchronized by three different methods (double thymidine block, thymidine-nocodazole block or mitotic shake-off)in five independent time courses. mRNA from the first and second double thymidine block experiments were converted to cDNA by standard methods using an oligo-dT/random hexamer mix and hybridized to 24K arrays; mRNA from the third double thymidine and thymidine-nocodazole block experiments were converted to cDNA using olido-dT alone and hybridized to 43K arrays; total RNA from the mitotic shake-off experiment was first amplified using a modified eberwine protocol, aRNA converted to cDNA by reverse transcription with random hexamer and hybridized to 43K arrays. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set

Array-CGH in human glial brain tumors

Project description:Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Characterization of DNA copy number changes in 54 glial brain tumors using a cDNA microarray-based comparative genomic hybridization method. Tumors: 54 fresh-frozen glioma specimens subjected to standard WHO classification. Specimens included astrocytic [3 juvenile pilocytic astrocytomas, 1 low-grade astrocytic glioma, 3 anaplastic astrocytomas, 31 glioblastomas (of these 3 secondary glioblastomas and 2 gliosarcomas)], oligodendroglial [5 oligodendrogliomas, 3 anaplastic oligodendrogliomas], and 7 anaplastic oligoastrocytomas tumors. One tumor had been classified as glioneuronal neoplasm. Human male and female genomic reference DNA was purchased from Promega (Promega, Madison, WI). The results provide insights into molecular genetic changes associated with gliomagenesis. Keywords: other

Gene expression profiling in human glial brain tumors

Project description:Gene expression profiling in 50 glial brain tumors and 4 normal brains using 42,000-feature cDNA microarrays (from total RNA). Tumors: 50 fresh-frozen glioma specimens subjected to standard WHO classification. Specimens included astrocytic [2 juvenile pilocytic astrocytomas, 1 low-grade astrocytic glioma, 1 anaplastic astrocytomas, 31 glioblastomas (of these 2 secondary glioblastomas and 2 gliosarcomas)], oligodendroglial [5 oligodendrogliomas, 3 anaplastic oligodendrogliomas], and 6 anaplastic oligoastrocytomas tumors. One tumor had been classified as glioneuronal neoplasm. Normal brain was purchased from Stratagene. Stratagene Universal Common Reference was used as reference RNA. The results provide insights into molecular mechanisms and pathways associated with gliomagenesis.

Oxidative metabolism and PGC-1 attenuate macrophage-mediated inflammation

Project description:Total RNA was prepared from three independent experimental replicates using Trizol reagent (Invitrogen) and validated by northern blot. Microarray experiments were performed with 20-25 ?g of total RNA, which was labelled with fluorescent nucleotides and hybridized to murine cDNA slides. Hybridized slides were interrogated via an Agilent scanner. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set
