Single gene drives prostate differentiation

Previous studies have found that loss of the gene Nkx3.1 results in impaired prostate differentiation in mice, prompting Aditya Dutta et al. to study the gene in greater detail. First, they confirmed that lack of Nkx3.1 in prostate cells results in reduced expression of a number of genes associated with prostate differentiation. The researchers then … Continue reading “Single gene drives prostate differentiation”

Previous studies have found that loss of the gene Nkx3.1 results in impaired prostate differentiation in mice, prompting Aditya Dutta et al. to study the gene in greater detail. First, they confirmed that lack of Nkx3.1 in prostate cells results in reduced expression of a number of genes associated with prostate differentiation.

The researchers then infected seminal vesicle epithelial cells with a virus expressing Nkx3.1, finding that inducing expression of this gene caused the seminal vesicle epithelium to convert into a prostate-like state in terms of structure, histological appearance and genetic markers.

Further investigation in human prostate cells identified several components of the regulatory network involved in this “tissue respecification” process, including certain histone-modifying enzymes. The authors suggest that further exploration of this network could help researchers understand the tissue-specificity of prostate cancer.
