Abstrakt: Cancer is a complex and multistage disease that causes suffering worldwide. Several mutations in tumor suppressor proteins are mostly responsible for tumorigenic development. Thus, determination of the mutations and developing a mutation targeted therapy are crucial in order to cure cancer. Moreover, since healthy cells do not have mutations in their tumor suppressor genes, mutation-specific treatment is responsible for selective treatment without harming a healthy tissue in the body. In this current study, lead borate nanoparticles (LB-Np) have been synthesized, and their effects on P53 mutant cancer cells were investigated. The synthesis method includes steps of mixing a borate buffer solution with the lead nitrate solution, washing the resulting precipitate with distilled water and eventually preparing stable LB-Np solutions. Cell viability analysis was conducted to identify the toxicity of LB-Np in HaCaT, A549, MCF7, and T47D cell lines. The changes in morphologies of breast cancer cell lines were demonstrated by using microscopical analysis. Additionally, alterations in gene expressions were determined in breast cancer cell lines after LB-Np treatment. This multidisciplinary study also identified the selective effect of LB-Np in cancer cell lines, in vitro. MTS and quantitative polymerase chain reaction assays demonstrated the effect of LB-Np were specific for p53 mutation cell line, T47D. Breast cancer cell line T47D has 580 C/T mutation which affects the activation of p53 tumor suppressor protein. However, LB-Np treatment effectively killed T47D cell lines and did not affect any other cell lines that have no p53 mutations such as MCF7, A549, and healthy HaCaT. Overall, synthesized LB-Np were found to be effective in p53-mutated cell lines and showed a remarkable selective anti-cancer activity.
