1 In the present study, we have examined the effect of methylmethane sulfonate (MMS) to HCT-116 human colon cancer cells on the phosphorylation of p53. Methyl Methanesulfonate tumor protein p53 Homo sapiens
2 In the present study, we have examined the effect of methylmethane sulfonate (MMS) to HCT-116 human colon cancer cells on the phosphorylation of p53. Methyl Methanesulfonate tumor protein p53 Homo sapiens
3 Results show that p53 protein becomes phosphorylated at serine 15 (Ser15) and Ser392 residues after treatment with MMS in a time-dependent manner. Methyl Methanesulfonate tumor protein p53 Homo sapiens
4 Increased levels of phospho-p53(Ser15) and phospho-p53(Ser392) were maintained up to 50 h of the MMS treatment. Methyl Methanesulfonate tumor protein p53 Homo sapiens
5 Increased levels of phospho-p53(Ser15) and phospho-p53(Ser392) were maintained up to 50 h of the MMS treatment. Methyl Methanesulfonate tumor protein p53 Homo sapiens
6 We also examined the involvement of probable kinase(s), which could be responsible for MMS-induced phosphorylation of p53 at Ser15 and Ser392. Methyl Methanesulfonate tumor protein p53 Homo sapiens
7 In vitro phosphorylation assay, carried out with the immunoprecipates of MMS-treated cells, showed an increased phosphorylation of p53 by c-Jun kinase 1 (JNK1) at early time points (2.5 h). Methyl Methanesulfonate tumor protein p53 Homo sapiens
8 The MMS-induced phosphorylation of p53 correlates with our previous findings of p53"s ability for increased sequence-specific DNA-binding and transcriptional activity in the cells treated with DNA alkylating agents. Methyl Methanesulfonate tumor protein p53 Homo sapiens
