Example sentences for: cisplatin
How can you use “cisplatin” in a sentence? Here are some example sentences to help you improve your vocabulary:
Combination of Gleevec and cisplatin synergistically inhibited the growth of A549 cells (Figure 4).
In response to DNA damage induced by ionizing radiation or chemical agents such as cisplatin, ATM kinase is activated and phosphorylates a number of downstream regulatory proteins important for cell cycle arrest, growth control, apoptosis and DNA repair [ 25 26 27 28 ] . AT patients are known to be predisposed to a variety of cancers, and the fibroblasts of AT patients are hypersensitive to ionizing radiation [ 29 ] . Although many reports showed the association of ATM mutation with risk of a number of different human malignancies, including prostate cancer, breast cancer, ovarian cancer, B-cell chronic lymphocytic leukemia and mantle cell lymphoma, the underlying molecular mechanism by which ATM gene causes these changes are not well understood [ 30 31 32 33 34 35 ] . There is so far no study showing the association of ATM gene with any solid tumor.
Cisplatin causes two types of DNA damage, DNA adducts and inter-stranded cross-linking, resulting in activation of apoptosis pathway in the target tumor cells [ 13 14 ] . Our results suggest that inhibition of tyrosine kinase activity of the potential targets by Gleevec appear to potentiate the effect of cisplatin in DNA-damage induced apoptosis in A549 cells.
Epigenetic gene silencing of the MGMT confers enhanced sensitivity to alkylating agents in cancer [ 24 25 ] . Lack of methylation, on the other hand, associates with high-risk of death [ 25 26 ] . It has been suggested that the high-levels of MGMT proteins contribute to a drug-resistant phenotype [ 27 ] . More than 90% of newly diagnosed GCTs and 70-80% of patients who present metastatic disease are cured with cisplatin-based chemotherapy [ 28 ] . However, 20-30% of the patients with metastatic disease exhibit resistance to the cisplatin curative regimen leading to high mortality in this group.
We have shown that Gleevec can exert its effect synergistically with cisplatin.
