The presence of R273H-P53 conferred the cancer cells with drug resistance not only against the widely used chemotherapeutic agents like cisplatin (CDDP) or 5-flurouracil (5-FU) but also against potent alternative modes of therapy like proteasomal inhibition.

These results indicate that mutant TP53 G245C and R273H can lead to more aggressive phenotypes and enhance cancer cell malignancy, which further uncover TP53 function in carcinogenesis and might be useful in clinical diagnosis and therapy of TP53 mutant cancers.

Many p53 cancer mutants, including the hot spot mutations (R175H, R248W and R273H), not only lose p53-dependent tumor-suppressor activities, but also acquire new oncogenic activities to promote cancer.

Our results show: (1) wild-type p53 stimulates the transcription of reporter genes with p53CON and RGC in their 5' region while most p53 mutants occurring in human cancers have lost this activity; (2) the R273H mutant retains transcriptional activity for the p53CON sequence but not RGC; (3) some mutants are temperature-sensitive for the transcriptional activity with the p53CON but not the RGC sequence; (4) p53 mutants vary in their ability to inhibit wild-type p53 transactivation but there is no difference between p53CON and RGC sequences; (5) lung cancer cells with endogenous mutant p53 proteins (M246I in H23 cells and R248L in H322 cells) retain transcriptional activity for the p53CON but not the RGC sequence.
