SOHLH2 is essential for synaptonemal complex formation during spermatogenesis in early postnatal mouse testes.

ABSTRACT: Spermatogenesis- and oogenesis-specific helix-loop-helix transcription factor 2 (SOHLH2) is exclusively expressed in germ cells of the gonads. Previous studies show that SOHLH2 is critical for spermatogenesis in mouse. However, the regulatory mechanism of SOHLH2 during early spermatogenesis is poorly understood. In the present study, we analyzed the gene expression profile of the Sohlh2-deficient testis and examined the role of SOHLH2 during spermatogenesis. We found 513 genes increased in abundance, while 492 genes decreased in abundance in 14-day-old Sohlh2-deficient mouse testes compared to wildtype mice. Gene ontology analysis revealed that Sohlh2 disruption effects the relative abundance of various meiotic genes during early spermatogenesis, including Spo11, Dmc1, Msh4, Prdm9, Sycp1,
