Objective:
To explore the effects of bears' bile on tumor cell p53 protein expression with different gene properties.
Methods:
The effects of bears' bile on the expression of p53 protein in 6 cancer cell strains were determined by Western blot and reverse transcription-polymerase chain reaction (RT-PCR) analysis. Results Western blot analysis showed that the expression of p53 protein in HaCaT, KUMA3, KUMA4 and KUMA6 cell strains with gene mutation were increased, but no change was found in HCT116 and KUMA5 cell strains without gene mutation. There was no quantitative change in p53 mRNA in all cell strains by analysis of p53 mRNA with
Conclusion:
The effects of bears' bile on p53 protein expression in cancer cell strains RT-PCR analysis system. could be different based on p53 gene properties,i. e. ,bears' bile only affect p53 protein of mutation type.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
