AIMS: Vascular smooth muscle cells (SMCs) and their derivatives are key contributors to the development of atherosclerosis. However, studying changes in SMC gene expression in heterogeneous vascular tissues is challenging due to the technical limitations and high cost associated with current approaches. In this paper, we apply Translating Ribosome Affinity Purification sequencing (TRAP-Seq) to profile SMC-specific gene expression directly from tissue. METHODS AND RESULTS: To facilitate SMC-specific translatome analysis, we generated SMCTRAP mice, a transgenic mouse line expressing EGFP-tagged ribosomal protein L10a (EGFP-L10a) under the control of the SMC-specific αSMA promoter...
