Cross species hybridization of human cancer cells xenografted into different mouse organ sites
To test gene expression changes of human cancer cells and mouse surrounding tissue cells during tumor progression, 4 different types of cancer cells (MDA-MB231Br3, PC14Br4, KM12M, A375SM) were injected into mouse brain, skin and orthotopic sites. RNAs containing human cancer cells and mouse surrounding tissue cells were extracted and hybridized into human and mouse arrays at the same times and it revealed the brain microenvironment induced complete reprogramming of metasized cancer cells, result...

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
