JI017 Induces Cell Autophagy and Apoptosis via Elevated Levels of Reactive Oxygen Species in Human Lung Cancer Cells.

Lung cancer is one of the most common malignant tumors and a leading cause of cancer-related death in the worldwide. Various anticancer drugs, such as cisplatin and pemetrexed, have been developed for lung cancer treatment but due their drug resistance and side effects, novel treatments need to be developed. In this study, the efficacy of the natural drug JI017, which is known to have few side effects, was tested in lung cancer cells. JI017 inhibited A549, H460, and H1299 cell proliferation. JI017 induced apoptosis, regulated apoptotic molecules, and inhibited colony formation. Additionally, JI017 increased intracellular ROS generation. JI017 downregulated PI3K, AKT, and mTOR expression. JI017 increased the cytosolic accumulation of LC3. We found that JI017 promoted apoptosis through ROS-induced autophagy. Additionally, the xenograft tumor size was smaller in JI017-treated mice. We found that JI017 treatment increased MDA concentrations, decreased Ki-67 protein levels, and increased cleaved caspase-3 and LC3 levels in vivo. JI017 decreased cell proliferation and increased apoptosis by inducing autophagy signaling in H460 and H1299 lung cancer cells. Targeting JI017 and autophagy signaling could be useful in lung cancer treatment.

Perception, attitudes, knowledge of using complementary and alternative medicine for cancer patients among healthcare professionals: A mixed-methods systematic review.

BACKGROUND: With the rapid increase in the prevalence of cancer worldwide, the utilization of complementary and alternative medicine (CAM) has increased among cancer patients. This review aimed to understand the perception, attitudes, and knowledge of healthcare professionals toward using CAM for cancer patients. METHODS: A mixed-methods systematic review was undertaken in four databases. Inclusion criteria were primary studies reporting perception, attitudes, and knowledge of healthcare professionals for using CAM for cancer patients were eligible. A mixed-methods convergent synthesis was carried out, and the findings were subjected to a GRADE-CERQual assessment of confidence. RESULTS: Forty-two studies were chosen. The majority of the studies were quantitative and had less than 100 participants. Most publications were from European countries, and oncology was the highest among the specialties. The review found the following themes: feasibility of having negative adverse effects, low expectations of using CAM among HCPs, potential positive effects of using CAM, specific CAM training may be helpful, no concrete regulations to promote CAM practice, and poor physician-patient communication. CONCLUSIONS: Nurses had more positive views than other professions; oncologists were concerned regarding herb-drug interactions; integration of CAM into the healthcare system was favorable; HCPs felt the need to participate in specific CAM training; and HCPs agreed that CAM education should be provided more regularly. Future studies should explore the studies views of cancer patients and details of in-depth evidence of CAM in oncology settings.
