Article Title: Expression profiling identifies genes involved in emphysema severity
doi: 10.1186/1465-9921-10-81
Figure Lengend Snippet: Comparison of mRNA expression in seven candidate genes between TPCH test (n = 30, microarray) and training set (n = 62 qRT-PCR data), with two public microarray datasets of lung tissue samples (Spira et al , , n = 34; and Golpon et al , n = 10) . Fold change represents mean expression ratio of moderate versus mild emphysema (TPCH training set), severe/mild emphysema versus normal (Spira et al ), or severe emphysema versus normal samples (Golpon et al ). The absence of a bar indicates the gene was not represented on the microarray platform.
Article Snippet: Lung and universal reference RNA (Stratagene, La Jolla, CA, USA) was reverse transcribed, labeled with Cy5 and Cy3 (Amersham/GE Healthcare, Buckinghamshire, England) respectively and co-hybridized onto a 22K Operon V2.1 Human Genome Oligo Microarray chip http://www.operon.com containing 21,329 70 mer probes representing ~14,200 named transcripts printed by the British Columbia Gene Array Facility http://www.microarray.prostatecentre.com .
