Maspin expression in CIN 3, microinvasive squamous cell carcinoma, and invasive squamous cell carcinoma of the uterine cervix.

Maspin is a serine protease inhibitor with tumor suppression activity. It is expressed in normal breast and prostate tissue but is downregulated or absent in breast and prostate tumors. Recent reports have shown that decreased expression is associated with a greater propensity for metastasis in oral squamous cell carcinomas.

The von Hippel-Lindau tumor suppressor stabilizes novel plant homeodomain protein Jade-1.

The von Hippel-Lindau disease gene (VHL) is the causative gene for most adult renal cancers. However, the mechanism by which VHL protein functions as a renal tumor suppressor remains largely unknown. To identify low occupancy VHL protein partners with potential relevance to renal cancer, we screened a human kidney library against human VHL p30 using a yeast two-hybrid approach.
