Page: << Prev | 1 | 2 Mice that were categorized as non-obese/severe combined immunodeficient (NOD/SCID) and treated with cisplatin (the standard chemotherapy agent) were found to have a 16 percent longer median survival time than untreated mice. NOD/SCID mice treated with α-CbT had an increased median survival time of 1.7-fold over the cisplatin-treated mice and 2.1-fold over untreated mice.
"The results of this study show that α-CbT, a powerful, high-affinity α-7-nAChR inhibitor, induces antitumor activity against NSCLC by triggering apoptosis," wrote Patrizia Russo of the Lung Cancer Unit of the National Cancer Research Institute in Genoa, Italy, in the news release.
Noncancerous cells did not appear to be affected by α-CbT, suggesting limited toxicity, the researchers found, but they noted that cancer cells with the most receptor binding sites seemed have the greatest treatment sensitivity.

"The goal of this research line is to explore the widest range of possibilities of intervention on the α7-nAChRs," Russo said. "We hope to move further on towards the clinical setting experimentation phase for the assessment of potentially new treatment strategies for NSCLC."
