RNA was isolated as modified from previous studies (Gumucio et al., 2014 (link); Grinstein et al., 2018 (link); Disser et al., 2019 (link)). Tendons were finely minced and then pulse homogenized in Qiazol (Qiagen, Germantown, MD, USA) containing 1μg of glycogen (Qiagen) using a TissueRuptor (Qiagen). RNA was isolated with an miRNA Micro Kit (Qiagen) supplemented with DNase I (Qiagen), and quality was assessed using a BioAnalyzer RNA Pico kit (Agilent Technologies, Santa Clara, CA, USA).
