leaf extract promoted biogenic CuO nanoparticles for the anti-apoptotic efficacies of NCI-H661 human lung adenocarcinoma cell line and following the PI3K/AKT/mTOR signaling pathway.

Plant-developed biogenic formulation of nanoparticles (NPs) is increasingly becoming a main trend in science dealing with materials or as specified as sustainable nano-medicines. A large portion of the ongoing nano-science studies are devoted to the bio-evoked eco-friendly bio-material due to their extensive pertinency. To achieve this end, copper oxide nanoparticles have been synthesized according to an environmentally sound approach employing leaf infusion. Such materials are consumed as the internal reducing agent while not utilizing coarse chemical substances or unusual heat. The derived NPs also get balanced by the bio molecular covering. This synthesis is specified through various analytical tools (including FT-IR, FE-SEM, and so forth as well as UV-Vis spectroscopy. The biological aspects were the focus of a recent study. The MTT test was used to evaluate the cytotoxic effects of CuO NPs on HUVEC and NCI-H661 cancer cells during a 48-h period. After being exposed to CuO NPs, the cancer cell showed a reduction in viability, with an IC50 value of 96 µg/mL. An in-depth experiment of the PI3K/AKT/mTOR pathway exhibited that CuO NPs influence apoptosis and cell proliferation in NCI-H661 cells through the modulation of the pathway. The pathway may play a role in the inhibition of the cell cycle and the induction of apoptosis triggered by CuO NPs. Therefore, CuO nanoparticles may be a useful natural anti-cancer treatment.
