ITSN1 and inflammatory bowel disease: However, in this study, we only performed qPCR to detect gene expressions, which was due to the fact that: (1) lnc-ITSN1-2 was observed to serve as a ceRNA for IL-23R via binding miR-125a in our subsequent in vitro experiments, which meant lnc-ITSN1-2 functioned in IBD based on RNA dimensions; however, (2) an insufficient budget limited our application of ELISA and antibodies purchasing for this experiment.
