Liposomal encapsulated curcumin attenuates lung cancer proliferation, migration and apoptosis

Lung cancer is one of the most diagnosed types of cancer worldwide, accounting to one fifth of cancer-related deaths. The high prevalence of lung cancer (LC) is due to various factors such as environmental pollution or lifestyle factors such as cigarette smoking. Non-small cell lung cancer (NSCLC) is the most diagnosed type of lung cancer. Despite the availability of several lines of treatment for NSCLC, including surgery, chemotherapy, radiotherapy, immunotherapy, and combinations of these, this disease still has very low survival rate, highlighting the urgent need to develop novel therapeutics. Phytoceuticals, or plant-derived bioactives are a promising source of biologically active compounds. Among these, curcumin is particularly relevant due to its wide range of anticancer, antioxidant, and anti-inflammatory activity. However, its poor solubility causes low bioavailability, severely limiting its clinical application. Encapsulation of curcumin in nanoparticle-based delivery systems such as liposomes holds promise to overcome this limitation. In the present study, we demonstrate promising
