NetSearch depicts interactions between Abp1p and both Srv2p and Act1p, consistent with the function of Abp1 in tethering Srv2p to the cytoskeleton.
Our earlier findings including a reduced number of elongated spermatids in the ABP-TG mice [ 26 ] also support the notion that higher than physiological concentrations of ABP affect spermatogenesis indirectly, through sequestration of androgens; the transformation of round spermatids to elongated spermatids is known to be the main androgen-dependent step in spermatogenesis [ 35 36 37 ] .
Apoptotic cells were identified by the TdT-mediated dUTP-biotin nick end labeling (TUNEL) method and detected either by flow cytometry [ 27 ] or by light microscopy in histological sections [ 28 ] . The results indicate that transgenic ABP alters the rate of testicular germ cell apoptosis throughout life, but it is most likely to cause its germ-cell depleting effect by promoting germ cell apoptosis during the critical pre-pubertal period ("puberty" in laboratory rodents occurs at 50-60 days of life and is defined as the first appearance of spermatozoa in the tail of the epididymis [ 29 30 ] ).
It is well established that TG mice overexpressing rat ABP [ 22 ] develop a testicular impairment [ 23 24 25 ] leading gradually to a reduced number of germ cells and infertility [ 26 ] . Various theories were proposed to explain the possible mechanisms behind this testicular impairment seen in the ABP-TG mice overexpressing rat ABP.
Taken together, the presence of increased levels of intra-testicular ABP in the TG mice after 7 days of age [ 25 26 ] and a wave of germ cell apoptosis seen in normal mice at 21 and 30 days of age in this study and by Rodriguez et al . [ 3 ] suggest that the heightened apoptotic wave found in our TG mice during the pre-pubertal period may be regulated by ABP.
