AHR and hemangioma: Interestingly, group 5 (blood vessel development and related terms), consisting of 55 DE lncRNAs (Additional file 2: Table S9), contains the above mentioned TIPARP-AS1 and FOXD2-AS1. Indeed, FOXD2-AS1 has shown an involvement in the progression of hemangioma [39], while the regulation of AhR signaling is related to the control of blood pressure and TIPARP-AS1 modulates it [36, 37].
