Transcriptome of the vomeronasal organ in Vmn2r1 knock out mice

ABSTRACT: <1. The vomeronasal organ (VNO) in the nose of most tetrapods is a sensory structure for the detection of pheromones and kairomones (intra-specific and inter-specific chemical signals) that initiate innate behaviours. It has two neuronal layers, each expressing distinct receptor sub-families coupled to different G-proteins. Neurones in the apical layer express a single vomeronasal receptor type 1 and the G?i2 G-protein. On the other hand, neurons in the basal layer express two or more vomeronasal receptors type-2 (V2Rs) and the G?o G-protein. In mice, V2Rs are organized into four families, A, B, D and C, with family-A and -C sub-divided into subfamilies A1-A10 and C1-C2. These gene families are expressed in a unique combinatorial pattern. Families A (subfamilies A1-A6), B and D are expressed monogenically and coexpress with the recently expanded family-C2 (6 genes, Vmn2r2 to Vmn2r7). While neurons expressing the phylogenetically ancient subfamily-C2 (1 gene, Vmn2r1) coexpress with family-BD and subfamilies A8-A10.We have generated a knock-out mouse for gene Vmn2r1 gene, using a Eucomm tm1b allele. This mouse is a valuable resource for further understanding the molecular organization of the VNO and its behavioural implications, in an evolutionary context. We propose here, to sequence the VNO of Vmn2r1 mutant mice. By studying the VNO transcriptome we hope to advance our knowledge of the genetic coding of pheromonal communication.
