Rhox1-KO Mouse

Rhox1, a member of the reproductive homeobox on the X chromosome (RHOX) gene family, is crucial for reproduction. Rhox genes are mainly expressed in reproductive tissues and have a role in regulating various reproductive features, especially gametogenesis in mammals [1,2].

In the mouse, Rhox genes are organized into three clusters (α, β, and γ) on the X chromosome. Rhox1, belonging to the α-cluster, has been shown to play a role in the differentiation of primordial germ cells and in spermatogenesis [1].

In conclusion, Rhox1 is essential for reproductive processes, specifically in the differentiation of primordial germ cells and spermatogenesis as revealed through studies in mouse models. Understanding its function can potentially contribute to a better understanding of infertility and associated human phenotypes related to impaired spermatogenesis [1].
