Analysis of neural transcriptome sequence data of BPH has revealed the presence of one AT, four types of Asts, and four corresponding receptors, allatotropin receptor (A16, ATR), AstA receptor (A2, AstAR), AstB (MIP) receptor (A10, AstBR, or MIPR), and AstC receptor (A1, AstCR) (Tanaka et al., 2014). This evidence concerns the gene ATR and benign prostatic hyperplasia.
