Transcriptomic profiling of S. cerevisiae wild type and aft2 mutant in response to exposure to selenite
The yeast S. cerevisiae does not require selenium for growth, so it is an excellent model to investigate the toxicity of this element without interference from its requirement as growth factor as occurs in animal cells. Exposure to selenite interferes with the yeast iron metabolism. Aft2 is a transcription factor related (with Aft1) to maintenance of iron homeostasis. We have found that aft2 cells are highly sensitive to selenite (a common environmental source for selenium). In these experiments...

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
