Deregulation of the ubiquitin/proteasome system has been implicated in the pathogenesis of many human diseases, including cancer. Ubiquitin-specific proteases (USP) are cysteine proteases involved in the deubiquitination of protein substrates. Functional connections between USP7 and essential viral proteins and oncogenic pathways, such as the p53/Mdm2 and(More)
In the general population, evaluation of lung cancer risk from radon in houses is hampered by low levels of exposure and by dosimetric uncertainties due to residential mobility. To address these limitations, the authors conducted a case-control study in a predominantly rural area of China with low mobility and high radon levels. Included were all lung(More)
The human USP7 deubiquitinating enzyme was shown to regulate many proteins involved in the cell cycle, as well as tumor suppressors and oncogenes. Thus, USP7 offers a promising, strategic target for cancer therapy. Using biochemical assays and activity-based protein profiling in living systems, we identified small-molecule antagonists of USP7 and(More)
BACKGROUND Several ecologic analyses have shown significant positive associations between mean indoor radon concentrations and risk of leukemia at all ages (acute myeloid leukemia and chronic lymphocytic leukemia) and for children (all leukemia, acute myeloid leukemia, and acute lymphoblastic leukemia [ALL]). As part of an age-matched, case-control study of(More)
Our recent study in Gansu Province, China reported an increasing risk of lung cancer with increasing residential radon concentration that was consistent with previous pooled analyses and with meta-analyses of other residential studies (Wang et al., Am. J. Epidemiol. 155, 554-564, 2002). Dosimetry used current radon measurements (1-year track-etch detectors)(More)
The etiology of pancreatic cancer remains elusive. It predominates in males and in certain ethnic populations (i.e., Polynesians and blacks). Primarily a disease of aging, it is rare in individuals under 40. Genetics is believed to play a very small part if any. While diabetics have higher than expected incidence and mortality rates, several recent studies(More)
Radon, an established lung carcinogen, remains the single most important environmental radiation exposure. Yet, an excess of lung cancer from breathing radon in homes has not been consistently demonstrated in studies conducted to date. To address several major problems that have hindered previous studies of lung cancer and radon in homes, we have embarked(More)
To test the validity of using pancreatic cancer mortality as an indicator of incidence, mortality data for 1969-1971 were compared to incidence data for those areas covered by the Third National Cancer Survey, which was conducted during the same time period. Good correlation was found for whites but not for blacks. Small numbers of black study subjects in(More)
