EPO and triple-A syndrome: The Connectivity Map (CMap), an online platform to compare input gene signatures with gene patterns in the contexts of over 450 000 chemical compounds, is a tool to identify compounds that create gene expression patterns opposite to or strengthening specific gene expression differences with a view to repurposing old drugs to new application.[20, 21, 22, 23] With the aim of finding molecules that might prevent and reverse EPO‐induced AAA, we uploaded the intersection genes to CMap.
