The in vivo mechanisms mediating these cellular and molecular actions of MSeA are currently be elucidated. Prev Next Table of Contents. However, in the prostate of MSeA-treated Pten KO mice, the staining intensity was remarkably elevated in ,ei epithelial cells by as much as 4 fold, estimated by ImagePro-Plus software Fig. Role for p53 in selenium-induced senescence.

Footnotes Disclosure of Potential Conflicts of Interest: Opposing effects of androgen deprivation and targeted therapy on prostate cancer prevention. In the G6Pase gene of a compound heterozygous patient LLPtwo mutations in exon 2 of one allele and exon 5 of the other allele were identified.
As shown in Fig. We also reported the efficacy of MSeA to inhibit prostate carcinogenesis in the transgenic adenocarcinoma mouse prostate TRAMP model which improved survival with no observable long-term adverse effect Mutations in the glucosephosphatase gene that cause glycogen storage disease type 1a. The prostate lobes were saved and processed individually for histopathology and biochemical analyses.
Selenomethionine and alpha-tocopherol do not inhibit prostate 1182 in the testosterone plus estradiol-treated NBL rat model. Prostate-specific deletion of the murine Pten tumor suppressor gene leads to metastatic prostate cancer. The critical role of androgen receptor AR signaling in PCa, even at the advanced metastatic castration-resistant stage, is well established and therapeutically exploited Superior in vivo inhibitory efficacy of methylseleninic acid against human prostate cancer over selenomethionine or selenite.
Preclinical and mechanistic research has demonstrated that SeMet has little in common with the mono-methylated methylselenol precursor Se forms MM-Sesuch as methylseleninic acid MSeAin terms of metabolism and anti-cancer activities 8 His-9, His, His, and His reside on the same side of the endoplasmic reticulum membrane as Arg Author manuscript; available in PMC Jan 1.
Unfortunately, recent studies have shown that inhibition of AR signaling by castration eli antagonist drugs inadvertently promotes the progression of stable HG-PIN to invasive carcinomas in Pten KO model 19raising concerns for utilization of these androgen deprivation strategies for chemoprevention in high risk men and PCa patients with PTEN deficiency or mutations.
Associated Data Supplementary Materials. Cancer Prev Res Phila ; 4: To our best knowledge, this study is the first 11882 which any form of Lwi has been tested in the Pten KO PCa mouse model for chemopreventive efficacy. All authors have no personal or financial conflict of interest and have not entered into any agreement that could interfere with our access to the data on the research or on our ability to analyze the data independently, to prepare articles, and to publish them.
We have previously identified six mutations in the G6Pase gene of glycogen storage disease type 1a patients and demonstrated that these mutations abolished or greatly reduced enzymatic activity of G6Pase, a leu protein of amino acids.
IHC and immunoblot Western were performed as previously described However, residues may be required for optimal G6Pase catalysis. The exon 2 mutation converts an arginine at codon 83 to pei cysteine R83C. The promising biochemical and cellular responses to the short-term MSeA intervention prompted us to evaluate its chemopreventive efficacy on Pten KO HG-PIN growth and progression in the second experiment with week administration.
Since p53 signaling 111882 likely to be intact in HG-PIN compared to advanced PCa, the selective super-activation of pmediated senescence by MSeA suggests a new paradigm of cancer chemoprevention by strengthening a cancer progression barrier pei induction of irreversible senescence with additional suppression of AR and AKT oncogenic signaling.

The long-term experiment was carried out with same design, except that the mice were weeks old at the start of the MSeA and water treatments 5 days per weeklasting for 25 weeks 8 mice per group.
At necropsy, the genitourinary GU tract was collected and weighed. Somat Cell Mol Genet. Evidence for the participation of independent translocation for phosphate and glucose 6-phosphate in the microsomal glucosephosphatase system.

National Center for Biotechnology InformationU. In addition to boosting and sustaining PP21Cip1 senescence as a cell proliferation barrier, long-term treatment with MSeA led to considerably reduced tumor burden Fig. Cancer Prev Res Phila ; 2: Disclosure of Potential Conflicts of Interest: Phase 3 clinical trial investigating the effect of selenium supplementation in men at high-risk for prostate cancer. Mouse genetic studies have demonstrated that loss of Pten in prostate epithelium rapidly causes HG-PIN that ultimately progresses to invasive adenocarcinoma and metastatic disease
