1 Combined bortezomib-based chemotherapy and p53 gene therapy using hollow mesoporous silica nanospheres for p53 mutant non-small cell lung cancer treatment. Bortezomib tumor protein p53 Homo sapiens
2 Then we found that the tumor-suppressing effect of BTZ or HMSNs-BTZ was compromised in p53 null/mutant NSCLC. Bortezomib tumor protein p53 Homo sapiens
3 Here, HMSN-based co-delivery of BTZ and the tumor-suppressor gene p53 was developed for p53 signal impaired NSCLC therapy. Bortezomib tumor protein p53 Homo sapiens
4 Here, HMSN-based co-delivery of BTZ and the tumor-suppressor gene p53 was developed for p53 signal impaired NSCLC therapy. Bortezomib tumor protein p53 Homo sapiens
5 Live/dead staining assay for treated H1299 cells exhibited wider distribution, and higher dead staining was prominent in the HMSNs-PEI-BTZ-p53 group when compared to that of the HMSNs-BTZ group with equivalent BTZ concentration, which was consistent with accumulated p53 expression. Bortezomib tumor protein p53 Homo sapiens
6 Live/dead staining assay for treated H1299 cells exhibited wider distribution, and higher dead staining was prominent in the HMSNs-PEI-BTZ-p53 group when compared to that of the HMSNs-BTZ group with equivalent BTZ concentration, which was consistent with accumulated p53 expression. Bortezomib tumor protein p53 Homo sapiens
7 Western blotting and real time PCR results showed that several p53 downstream genes responded strongly and synergistically to BTZ function and p53 restored expression (accumulation of p21 and bax, activation of caspase 3, down-regulation of Bcl-2, etc.). Bortezomib tumor protein p53 Homo sapiens
