We were highly concerned by the finding that many cell lines had controversial tp53 status including popular cell lines such as those from the nci 60 panels.
P53 status prostate cancer cell lines.
There is growing evidence that these mutant p53s have both lost wild type p53 tumor suppressor activity and gained functions that help to contribute to malignant progression.
We assessed mi 219 a small molecule inhibitor of mdm2 with improved pharmacokinetics over nutlin 3 for sensitization of prostate cancer cells to radiotherapy and androgen deprivation therapy a.
One strain lncap gw had a mutation in one of two alleles at position 273 arg.
Analysis of p53 mutation status in human cancer cell lines.
Cell lines with a wt p53 gene.
P53 gene structure and chromosome 17p alleles were studied in the three human prostate cancer cell lines lncap du 145 and pc 3.
Peitc inhibits cell proliferation induces apoptosis and reactivates p53 mutants in prostate cancer cell lines.
Although no genetic alteration is found in the p53 gene of these cell lines it is possible that.
Four tables are presented for each type of cancer.
Many different types of cancer show a high incidence of tp53 mutations leading to the expression of mutant p53 proteins.
One strain lncap gw had a mutation in one of two alleles at position 273 arg his.
Our laboratory has two separate culture lines of the lncap human.
One variable that may affect the radiosensitivity of prostate tumor cells is their p53 status because this gene controls radiation induced cell cycle arrest apoptosis and the repair of dna damage.
P53 gene structure and chromosome 17p alleles were studied in the three human prostate cancer cell lines lncap du 145 and pc 3.
Upon g2 m checkpoint activation caspase 8 cleaves the de ubiquitinase usp28 inhibiting its ability to stabilize p53.
Cell line p53 handbook v 1 0 this version of the p53 handbook includes the p53 status of 1 300 cell lines.
External beam radiation therapy is an effective therapy for localized prostate cancer although failures occur at high rates.
This leads to a de facto p53 loss enabling cancer cells to escape p53 dependent apoptosis in favor of mitotic cell division.
Berglind h pawitan y kato s ishioka c and soussi t.
Increased murine double minute 2 mdm2 expression independent of p53 status is associated with increased cancer specific mortality for men with prostate cancer treated with radiotherapy.
