Rationale for change

HIF1a is a transcription factor that does not leave the cell, thus it is more appropriate to say that it acts "in" renal fibroblasts instead of "on" them.

This topic isn't covered by FA or Robbins, Costanzo is where the error originated from, and I don't have access to UWorld or Amboss, so the best source I can offer is this highly cited review paper on the topic authored by the current chair of nephrology at Vanderbilt: PMID 16554418 (see second sentence of abstract). Thanks as always!
