LDLR and sarcoidosis: Notably, we observed the same direction in the transcript regulation, in all the 43-shared transcripts, except for one, OLR1, a low density lipoprotein receptor involved in Fas-induced apoptosis, this gene was upregulated in TB and down regulated in sarcoidosis, over-expression of OLR1 result in upregulation of NF-κB and its target pro-oncogenes [38].
