The pig jejunal explants were homogenized using 2 mL plastic bead tubes (MT Biomedicals, Illkirch, France) in 1 mL of Extract-All reagent (Eurobio, Courtaboeuf, France) in a Precellys Evolution tissue homogenizer (Bertin Technologies, Montigny-le-Bretonneux, France). ARN isolation and RT-qPCR were performed as described elsewhere [70 (link),71 (link)]. Data analysis was carried out using LinRegPCR freeware [72 (link)], and normalized against two reference genes, TATA-Box Binding Protein (TBP) and Hypoxanthine guanine phosphoribosyl transferase 1 (HPRT1). Primers are described in Supplementary Table S2.
