Disease relevance of NKX3-1

  • We demonstrate that PTEN loss causes reduced NKX3.1 expression in both murine and human prostate cancers [1].
  • In 12 cases that also had high-grade prostatic intraepithelial neoplasia, NKX3.1 expression levels were similar in preinvasive and invasive cancer cells and significantly lower than adjacent normal cells [2].
  • Single-strand conformational polymorphism analysis of 48 radical prostatectomy cancer specimens and 3 metastases for the entire coding region of NKX3.1 showed no tumor-specific sequence alterations in 50 specimens and total absence of the gene in 1 specimen known to have a biallelic deletion of 8p21 [3].
  • Here we show that NKX3.1 expression is dramatically down-regulated in testicular cancer of germ cell origin [4].
  • Immunohistochemical analysis on a tissue microarray containing 510 testicular tissue samples indicate that NKX3.1 is expressed at high levels in normal germ cells and in carcinoma in situ, but is sharply decreased or absent in most seminomas and all embryonal carcinomas [4].

Physical interactions of NKX3-1

  • Using NMR spectroscopy, three conserved motifs in a construct containing the N-terminal region and homeodomain of NKX3.1 were observed to interact with the MADS box domain of SRF [17].
 

Regulatory relationships of NKX3-1

  • Our results provide biochemical and cellular biologic evidence that NKX3.1 is down-regulated by p53 over-expression in prostate cancer cells [18].
  • NKX3.1 is an androgen-regulated prostate-specific homeobox gene that is thought to play an important role in prostate development and cancerogenesis [19].
