Zfp703-flox Mouse

Zfp703, with its functions still being explored, is involved in key biological pathways. It has been shown to be related to the Wnt/β -catenin signaling pathway, which controls embryonic development and adult stem cell maintenance. Malregulation of this pathway can lead to embryonic malformations and cancer, highlighting Zfp703's potential importance in these processes [1].

One study demonstrated that Zfp703 is a Wnt target gene. It inhibits Wnt/β -catenin activity in Wnt reporter assays and Wnt -dependent mesoderm differentiation in embryonic stem cells. Zfp703 binds directly to Tcf1 to prevent β -catenin/Tcf1 complex formation, functioning independently of the Groucho/Tle transcriptional corepressor [1]. Another study found that Zfp703 is among the genes whose expression is affected during retinoic acid -induced differentiation of neuromesodermal progenitors, suggesting its role in body axis extension [2]. Additionally, in the context of prostate gland adaptation to the hypoandrogenic environment, Zfp703 was identified as one of the transiently expressed transcription -regulating genes, with its mRNA present in both epithelial and stromal cells [3].

In conclusion, Zfp703 plays diverse roles in embryonic development-related processes such as mesoderm differentiation and body axis extension, as well as in the prostate gland's response to androgen deprivation. These findings from various studies enhance our understanding of Zfp703's biological functions and its potential implications in related diseases. Although no KO/CKO mouse model findings were explicitly presented in the provided references, the identified functions give a basis for further in-vivo functional studies.
