Figure 2. 51 differentially-expressed RBPs and their functional enrichment. (A, B) The volcano plot (A) and the heat map (B) indicated that 51 of 1542 RBPs were differentially expressed between the control and NOA testicular samples. (C) The functional annotation of the 51 RBPs. Abbreviations: RBP: RNA-binding protein; NOA: non-obstructive azoospermia.
