PHF19 and pemphigus foliaceus: mRNA analysis revealed that PHF19 was upregulated in endometrial cells treated with both control and endo PF when compared to media alone cells with the expression of PHF19 reaching almost 11.5-fold in the endo PF treated cells (p = 0.0474), suggesting that PHF19 may be working along with miR-155 to bring the PRC2 complex to its target and promote endometriosis (Figure 8).
