Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.

Ascorbic acid, also referred to as vitamin C(Vc), is an important nutrient found in fruits and vegetables that promotes produce quality and human health. Rosa roxburghii is an underutilized natural fruit that contains very high levels of Vc. However, the Vc content of R. roxburghii varies considerably during plant development and ripening. To better understand the molecular mechanisms that underlie fluctuations in Vc content of R. roxburghii fruit at different developmental stages, we performed transcriptomic and metabolomic analyses and identified two significant gene networks/modules and 168 transcription factors directly involved in Vc synthesis. Promoter analysis of two core genes involved in Vc synthesis, RrGGP and RrGalUR, revealed the presence of a retroviral long terminal repeat(LTR) insert in the RrGalUR promoter. Using yeast one-hybrid and dual-luciferase assays, we demonstrated that the transcription factors RrHY5H and RrZIP9 bind to the promoter of RrGGP to promote its expression. RrZIP6 and RrWRKY4 bind to the LTR in the RrGalUR promoter to promote its expression. Our results reveal a molecular mechanism that controls Vc synthesis and accumulation in R. roxburghii fruit.
