SCI REP:GGNBP2对睾丸形态和精子发育十分重要

2017-06-07 MedSci MedSci原创

配子生成素结合蛋白2(GGNBP2)被认为是一种肿瘤抑制因子,并已经通过几项研究证实。据报道,GGNBP2通过调节滋养层干细胞,促进妊娠维持,并对其至关重要。配子生成素(GGN)是成人睾丸中表达的睾丸生殖细胞的特异性基因。作为一种潜在的GGN1的相互作用蛋白,GGNBP2在精子发生过程中的作用尚未明确。

配子生成素结合蛋白2(GGNBP2)被认为是一种肿瘤抑制因子,并已经通过几项研究证实。据报道,GGNBP2通过调节滋养层干细胞,促进妊娠维持,并对其至关重要。配子生成素(GGN)是成人睾丸中表达的睾丸生殖细胞的特异性基因。作为一种潜在的GGN1的相互作用蛋白,GGNBP2在精子发生过程中的作用尚未明确。我们构建了GGNBP2的杂合敲除小鼠,并进行杂交。我们发现,在杂交后代中,GGNBP2纯合敲除(KO)小鼠的数量严重减少。GGNBP2 的KO幼仔正常发育,但是雄性小鼠的生殖力显着降低。在这些雄性的GGNBP2 纯合KO小鼠中,唯一的病理学发现是睾丸异常形态和精子缺失。另外,在GGNBP2 KO小鼠的睾丸中观察到凋亡增加的现象。SOX9染色显示生精小管中没有SOX9阳性的支持细胞。在纯合小鼠中,增殖细胞核抗原(PCNA)阳性细胞定位于曲细精管的内腔。这些结果表明,GGNBP2通过影响SOX9阳性支持细胞的形态和功能,从而在精子发生中起关键作用。
