A Legal Approach to Cancer Epidemiology in Public Health

The Public Health Act encompasses scientific research and law enforcement as causes, distributions, and preventive factors for diseases and injuries of a particular population. Today, the Public Health Law is growing into a field that expects to cultivate and utilize lawful practitioners who can apply specialized legal skills in health policy development and public health performance. The multidisciplinary approach of the Public Health Act integrates the legal and scientific elements of the field and the workforce, characterized by a more dynamic understanding of the health impact of legislation and the rapid deployment of effective policies. Thus, legal health interventions that manage and treat diverse populations need to be evaluated more rigorously and quickly. In addition, funding for policy surveillance and other legislation and policy mapping needs to be more sophisticated to maximize utility and avoid duplication. This study investigated legal interventions to manage and treat various groups of populations for health and discussed the necessity of public health laws.     

Involvement of ER stress and reactive oxygen species generation in anti-cancer effect of CKD-516 for lung cancer

CKD-516 (Valecobulin), a vascular-disrupting agent, inhibits microtubule elongation. We evaluated the effect of CKD-516 on lung cancer cells and the underlying molecular mechanisms. The effects of S516, an active metabolite of CKD-516, were evaluated in HUVECs and three lung cancer cell lines and by a microtubule polymerization assay. Tubulin cross-linking was used to identify the binding site of S516 on tubulin, and Western blotting was performed to identify the intracellular pathways leading to cell death. Subcutaneous lung cancer xenograft models were used to assess the in vivo effect of CKD-516 on tumor growth. S516 targeted the colchicine binding site on β-tubulin. In lung cancer cells, S516 increased endoplasmic reticulum (ER) stress and induced reactive oxygen species (ROS) generation by mitochondria and the ER. In addition, CKD-516 monotherapy strongly inhibited the growth of lung cancer xenograft tumors and exerted a synergistic effect with carboplatin. The findings suggest that CKD-516 exerts an anticancer effect in company with inducing ER stress and ROS production via microtubule disruption in lung cancer cells. CKD-516 may thus have therapeutic potential for lung cancer.
