Project description:Pain management is an important issue in veterinary medicine, requiring biomarkers with high sensitivity and specificity for the timely and effective treatment. Emerging evidence suggests that miRNAs are promising pain-related markers. The aims were to profile the circulating miRNA signature in plasma of turtles (Trachemys scripta) and point out potential candidate biomarkers of pain. Plasma of female turtles underwent surgical gonadectomy were collected 24h pre-surgery, and 2.5h and 36 h post-surgery. The expression of miRNAs was profiled by Next Generation Sequencing and the dysregulated miRNAs were validated using RT-qPCR. The diagnostic value of miRNAs was calculated by ROC curves.
Project description:The functional complexity of nucleus accumbens (NAc) has been extensively characterized in recent years. However, the molecular and cellular heterogeneity beyond the established D1 and D2 medium spiny neuron (MSN) subtypes, which likely underlie its diverse functions, are not well understand. Here, we present the cell taxonomy of mouse NAc generated from single-cell transcriptomic profiling, which not only reveals a rich cellular heterogeneity within both NAc MSN and interneuron populations, but also identified tight correlation between the transcriptional feature and spatial distribution of NAc neuron subtypes, supporting the notion that functional heterogeneity of NAc sub-regions can arises from differential distribution of molecularly distinct neuronal populations. To further test this idea, we focused on a D1 MSN subtype identified from our analysis and demonstrated that these cells possess distinct anatomic location, neural connection and more importantly, behavioral function. Collectively, our work not only created comprehensive cell taxonomy of NAc, but also provided insights into how functional heterogeneity is embedded in this brain region.
