Aim:To identify a novel isoform of adaptin 2 beta subunit (named Ap2β-NY) and to investigate its relationship with testicular development and spermatogenesis.Methods:Using a human testis cDNA microarray,a clone (Ap2β-NY), which was strongly expressed in adult testes but weakly expressed in embryo testes,was sequenced and analyzed. Using polymerase chain reaction (PCR),the tissue distribution and expression time pattern of Ap2β-NY were determined. Results:Ap2β-NY was identified and has been deposited in the GenBank (AY341427).The expression level of Ap2β-NY in the adult testis was about 3-fold higher than that in the embryo testis.PCR analysis using multi-tissue cDNA indicated that Ap2β-NY was highly expressed in the testis,spleen,thymus,prostate,ovary,blood leukocyte and brain,but not in the heart,placenta,lung,liver,skeletal muscle,kidney and pancreas.In addition,Ap2β-NY was variably expressed in the testes of patients with spermatogenesis-disturbance and spermatogenesis-arrest but not expressed in those of Sertoli-cell-only syndrome,which implied that,in the testis,Ap2β-NY was restrictively ex- pressed in germ cells.Conclusion:Ap2β-NY is an isoform of Ap2β and may be involved in regulating the process of spermatogenesis and testis development. 展开更多
