Six annotated genes were selected for validation analysis: LIF interleukin 6 family cytokine (LIF) and interleukin 10 (IL10), originating from the adenomyosis gene list, and JunB proto-oncogene, AP-1 transcription factor subunit (JUNB), interleukin 6 (IL6), Fos proto-oncogene, AP-1 transcription factor subunit (FOS) and suppressor of cytokine signalling 3 (SOCS3) from the endometriosis gene list (Figure 1). The gene discussed is FOSB; the disease is endometriosis.
