Using receptor knockout mice we examined changes in sperm nucleoproteins and chromatin architecture. The expressions of transition proteins 1/2 (TP1/2) and protamine-2 (PRM-2) were greatly diminished at 21 days, but returned to normal at 35 days and 3 months after birth. However, protein components in chromatin were quite different. Western blots detected a reduction in PRM1/2 and prolonged retention of mono-ubiquitinated histone 2A (uH2A) in the epididymal sperm from adult mutants. Two forms of mono- and poly-uH2A were present in sonication-resistant testicular spermatids in normal mice, whereas only an elevated mono-uH2A was detectable in mutants. Decrease in PRM1/2 and retention of mono-uH2A was coincident with reduction in TP1/2 in premature spermatids. Thus lack of FSHR signaling impairs expression of TP1/2 and PRM-2 at an early stage of post-natal development causing delayed spermatogenesis. In the adult, absence of FSHR signaling prolongs retention of mono-uH2A, leading to impair transition of basic nucleoproteins and chromatin remodeling during mouse spermatogenesis."xsd:string |
