MYC and Anxiety: Rats subjected to CUMS displayed defective β-catenin signaling, potentially leading to compensatory activation of 5-HT1 A. Consistently, the CUMS + MO group exhibited normalized 5-HT1 A and 5-HT signaling, accompanied by reduced pThr183-Erk and its downstream targets, c-myc and miR- 203, to mitigate pathological anxiety.
