Description
To examine the role of SPS1 in mammals, we generated a Sps1 knockout mouse and found that systemic SPS1 deficiency was embryonic lethal. Embryos were clearly underdeveloped by E8.5 and virtually reabsorbed by E14.5. Removal of Sps1 specifically in hepatocytes using Albumin-cre preserved viability, but significantly affected expression of a large number of mRNAs involved in cancer, embryonic development and the glutathione system. Particularly notable was the extreme deficiency of glutaredoxin 1 (GLRX1) and glutathione-S-transferase omega 1. To assess these phenotypes at the cellular level, we targeted the removal of SPS1 in F9 cells, a mouse embryonal carcinoma cell line, which recapitulated changes in the glutathione system proteins. We further found that several malignant characteristics of SPS1-deficient F9 cells were reversed, suggesting that SPS1 has a role in supporting and/or sustaining cancer. In addition, the increased ROS levels observed in F9 SPS1/GLRX1 deficient cells were reversed and became more like those in F9 SPS1 sufficient cells by overexpressing mouse or human GLRX1. The results suggest that SPS1 is an essential mammalian enzyme with roles in regulating redox homeostasis and controlling cell growth.

Description
Self-renewal and differentiation of spermatogonial stem cells (SSCs) provides the foundation for testis homeostasis, yet mechanisms that control their functions in mammals are poorly defined. We used microarray transcript profiling to identify specific genes whose expression are augmented in the SSC-enriched Thy1+ germ cell fraction of mouse pup testes. Comparisons of gene expression in the Thy1+ germ cell fraction to the Thy1-depeleted testis cell population identified 202 genes that are expressed 10-fold or higher in Thy1+ cells. This database provided a mining tool to investigate specific characteristics of SSCs and identify novel mechanisms that potentially influence their functions.
