Arterial stiffness and cardiac dysfunction in Hutchinson-Gilford Progeria Syndrome corrected by inhibition of Lysyl Oxidase

Purpose: Arterial stiffening is a hallmark of premature aging in Hutchinson-Gilford Progeria Syndrome (HGPS), but the molecular regulators remain unknown. Here, we show that the LMNAG609G mouse model of HGPS recapitulates the premature arterial stiffening seen in human HGPS. To gain a better understanding of potential stiffness-regulators in LMNAG609G mice, we performed RNA-sequencing analysis on cleaned descending aortas from 2- and 24-month WT and 2-month LMNAG609G mice on a C57BL6 background.Methods: Descending aortas containing the intimal, medial and adventitial layers were isolated from 2- and 24-month male WT and 2-month HGPS mice, and RNA was extracted using the RNeasy Plus Micro kit (Qiagen 74034). The high-throughput library was prepared using the TruSeq stranded total RNA (ribo-Zero) kit (Illumina 20037135). Paired-end sequencing was performed on a HiSeq4000 Sequencing System (Illumina) and generated 14-30 million reads/sample.
