Cannabinoid WIN 55,212-2 Inhibits Human Glioma Cell Growth by Triggering ROS-Mediated Signal Pathways. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6612592. [PMID: 33977107 PMCID: PMC8087470 DOI: 10.1155/2021/6612592] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 03/25/2021] [Accepted: 04/01/2021] [Indexed: 11/17/2022]
Abstract
Glioblastoma is a highly invasive primary malignant tumor of the central nervous system. Cannabinoid analogue WIN 55,212-2 (WIN) exhibited a novel anticancer effect against human tumors. However, the anticancer potential and underlying mechanism of WIN against human glioma remain unclear. Herein, the anticancer efficiency and mechanism of WIN in U251 human glioma cells were investigated. The results showed that WIN dose-dependently inhibited U251 cell proliferation, migration, and invasion in vitro. WIN treatment also effectively suppressed U251 tumor spheroids growth ex vivo. Further studies found that WIN induced significant apoptosis as convinced by the caspase-3 activation and release of cytochrome C. Mechanism investigation revealed that WIN triggered ROS-mediated DNA damage and caused dysfunction of VEGF-AKT/FAK signal axis. However, ROS inhibition effectively attenuated WIN-induced DNA damage and dysfunction of VEGF-AKT/FAK signal axis and eventually improved U251 cell proliferation, migration, and invasion. Taken together, our findings validated that WIN had the potential to inhibit U251 cell proliferation, migration, and invasion and induce apoptosis by triggering ROS-dependent DNA damage and dysfunction of VEGF-AKT/FAK signal axis.

Abstract
Introduction Lung cancer is the most common cancer in men living Eastern Morocco. We here present the first report on the clinical, pathological and therapeutic features of lung cancer in Eastern Morocco. Methods We conducted a retrospective study of 738 patients diagnosed with lung cancer at the Hassan II, Oncology Center between October 2005 and December 2014. Results Among the cases studied, 671 patients were men and 67 women; 95.01% of men and 1.54% of women were smokers. The average age of patients was 59.1 ± 11.9 years. Most patients (97%) were diagnosed at advanced stage disease. Only 4 out of 227 patients with advanced adenocarcinoma underwent molecular test. In addition, no patient in our series received targeted therapy. In this series, 20.46% of patients had less than 50 years. Compared to patients aged 50 years and older, cannabis consumption was higher (p<0.001) in patients less than 50 years and as well as a higher rate of adenocarcinoma (p<0.01). By contrast, in these patients, tobacco consumption was lower (p<0.001) as well as the rate of squamous cell carcinoma (p<0.01) and small cell cancer (p<0.05). Conclusion Unlike Western countries, in Eastern Morocco lung cancer is diagnosed late, affects younger people and access to molecular tests is still very limited. These results justify the need to implement effective programs against lung cancer as well as to facilitate access to molecular tests and new therapeutic tools in Eastern Morocco.

Abstract
A marked increase in the morbidity and mortality of a large number of broncho-pulmonary diseases has been documented in relation to smoking. The influence of tobacco smoking on various respiratory conditions. is discussed: incidence, severity or natural history modification of some respiratory illnesses: obstructive lung diseases (COPD, asthma), lung cancer, bacterial, viral respiratory infections, with the impact of smoking on tuberculosis. Finally, the relationship of tobacco with diffuse interstitial lung disease: protective role of smoking (controversial in sarcoidosis, real in hypersensitivity pneumonitis). The benefits of smoking cessation are described.

Abstract
Background Long-term exposure to tobacco smoke causes local inflammation in the airways that involves not only innate immune cells, including NK cells, but also adaptive immune cells such as cytotoxic (CD8+) and helper (CD4+) T-cells. We have previously demonstrated that long-term tobacco smoking increases extracellular concentration of the CD4+-recruiting cytokine interleukin (IL)-16 locally in the airways. Here, we hypothesized that tobacco smoking alters IL-16 biology at the systemic level and that this effect involves oxygen free radicals (OFR). Methods We quantified extracellular IL-16 protein (ELISA) and intracellular IL-16 in NK cells, T-cells, B-cells, and monocytes (flow cytometry) in blood samples from long-term tobacco smokers with and without chronic obstructive pulmonary disease (COPD) and in never-smokers. NK cells from healthy blood donors were stimulated with water-soluble tobacco smoke components (cigarette smoke extract) with or without an OFR scavenger (glutathione) in vitro and followed by quantification of IL-16 protein. Results The extracellular concentrations of IL-16 protein in blood did not display any substantial differences between groups. Notably, intracellular IL-16 protein was detected in all types of blood leukocytes. All long-term smokers displayed a decrease in this IL-16 among NK cells, irrespective of COPD status. Further, both NK and CD4+ T-cell concentrations displayed a negative correlation with pack-years. Moreover, cigarette smoke extract caused release of IL-16 protein from NK cells in vitro, and this was not affected by glutathione, in contrast to the decrease in intracellular IL-16, which was prevented by this drug. Conclusion Long-term exposure to tobacco smoke does not markedly alter extracellular concentrations of IL-16 protein in blood. However, it does decrease the intracellular IL-16 concentrations in blood NK cells, the latter effect involving OFR. Thus, long-term tobacco smoking exerts an impact at the systemic level that involves NK cells; innate immune cells that are critical for host defense against viruses and tumors – conditions that are overrepresented among smokers.

Abstract
Choline kinase α (CHKA), the enzyme that converts choline to phosphocholine, has been studied in human carcinogenesis widely. However, the expression and underlying clinicopathological characteristics of CHKA in lung adenocarcinoma remains elusive. In the present study, a tissue microarray of 119 pairs of lung adenocarcinoma samples and corresponding adjacent normal mucosae was used to analysis CHKA expression by immunohistochemistry, and CHKA was observed to exhibit enhanced expression in lung adenocarcinoma tissues. Elevated CHKA expression in lung adenocarcinoma tissues at the gene and protein level was observed. The levels of CHKA expression were closely associated with the poor prognosis status of lung adenocarcinoma patients. Furthermore, certain clinicopathological characteristics such as tumor diameter and differentiation were observed to be significant in those lung adenocarcinoma patients who displayed enhanced CHKA expression. The analysis of CHKA expression could provide a more precise way to predict the prognosis of lung adenocarcinoma patients. Collectively, the present study revealed a novel biomarker in lung adenocarcinoma, and indicated that CHKA may be a promising prognostic marker and therapeutic target for lung adenocarcinoma.

Abstract
BACKGROUND To compare the current histologic distribution of lung cancer in Lebanon to the worldwide trends, according to the 2004 WHO Classification. MATERIALS AND METHODS 1,760 patients with a pulmonary pathology examination at Hotel-Dieu de France University Hospital between July 2009 and July 2014 were included. RESULTS Some 676 out of the total investigated patients (38.4%) had a lung tumor. In 665 (98.4%) the tumors were malignant, with a mean age at diagnosis of 63.8 years and a male/female (M/F) sex ratio of 1.7:1. Among the malignant tumors, 86.2% were epithelial tumors with a mean age at diagnosis of 64.8 years and an M/F sex ratio of 1.9. Other malignant tumors consisted of metastatic tumors (10.2%), lymphoproliferative tumors (2.1%) and mesenchymal tumors (1.5%). Most common carcinoma subtypes were adenocarcinoma (48.0%), squamous cell carcinoma (23.0%) and small cell carcinoma (13.3%). Carcinoid tumors were the only carcinoma subtype with an M/F sex ratio below 1 (0.7). Salivary gland tumors were the carcinoma with lowest mean age at diagnosis (45.5 years). CONCLUSIONS The histologic distribution of lung tumors in Lebanon is similar to that in developed countries. We believe this resemblance is due to common smoking habits, known to be responsible for the increase of lung adenocarcinoma at the expense of other subtypes.

Abstract
Tobacco smoking is the leading cause of lung cancer. This cancer is the most specific indicator of the effects of tobacco on health. Regardless of the type of lung cancer and the stage of the disease, continued smoking has a negative impact on its development and its treatment. For this reason, smoking cessation is an essential step in the management of patients with lung cancer who smoke. It has been clearly demonstrated that quality of life is worse in smokers than in non-smokers. The aim of this general review is to study the relationship between tobacco use and quality of life specifically in patients with lung cancer. Among the twelve studies selected, six of them clearly demonstrate a deleterious effect of continued smoking tobacco or a beneficial effect of smoking cessation on the quality of life in patients with lung cancer. These findings should lead clinicians to offer support to smokers with lung cancer in order to assist them to quit smoking.

Abstract
Cannabis is the most commonly smoked illicit substance in the world. It can be smoked alone in plant form (marijuana) but it is mainly smoked mixed with tobacco. The combined smoking of cannabis and tobacco is a common-place phenomenon in our society. However, its use is responsible for severe pulmonary consequences. The specific impact of smoking cannabis is difficult to assess precisely and to distinguish from the effect of tobacco. Marijuana smoke contains polycyclic aromatic hydrocarbons and carcinogens at higher concentration than tobacco smoke. Cellular, tissue, animal and human studies, and also epidemiological studies, show that marijuana smoke is a risk factor for lung cancer. Cannabis exposure doubles the risk of developing lung cancer. This should encourage clinicians to identify cannabis use and to offer patients support in quitting.

Abstract
Marijuana (cannabis) remains a controversial drug in the twenty-first century. This paper considers current research on use of Cannabis sativa and its constituents such as the cannabinoids. Topics reviewed include prevalence of cannabis (pot) use, other drugs consumed with pot, the endocannabinoid system, use of medicinal marijuana, medical adverse effects of cannabis, and psychiatric adverse effects of cannabis use. Treatment of cannabis withdrawal and dependence is difficult and remains mainly based on psychological therapy; current research on pharmacologic management of problems related to cannabis consumption is also considered. The potential role of specific cannabinoids for medical benefit will be revealed as the twenty-first century matures. However, potential dangerous adverse effects from smoking marijuana are well known and should be clearly taught to a public that is often confused by a media-driven, though false message and promise of benign pot consumption.

Abstract
Despite all efforts at management, prognosis of advanced lung cancer is extremely poor, with a median survival time of ~1 year. The number of cancer patients aged >70 years is significantly increased among the cancer patient population. The aim of this study was to investigate the clinical importance of age in lung cancer. Data from 110 patients with histologically confirmed lung cancer, who were treated and followed up in the Institute of Oncology, University of Istanbul, were recorded from medical charts. There were 100 (91%) males with a median age of 59 years (range, 35-88 years). The majority of patients had non-small cell lung cancer (NSCLC; 84%) and metastatic stage (56%). The rate of positive response to chemotherapy was lower in elderly patients (P=0.01) and the incidence of anemia was higher compared with that in younger patients (P=0.02). The majority of mortalities occurred in elderly patients (P=0.01). The median survival time of elderly patients was significantly lower compared with that of younger patients (37.8 vs. 57 weeks; P=0.009). The 1-year survival rates in younger and elderly patients were 67.3 and 42.5%, respectively. In multivariate analysis, elderly patients also had significantly poorer survival (P=0.023). In the group of elderly patients, analyses revealed that significant prognostic factors, including stage of disease and serum lactate dehydrogenase (LDH) levels, were associated with survival. Elderly patients diagnosed with small cell lung cancer had a poorer outcome compared with those with NSCLC (P=0.009), and older patients with elevated serum LDH levels had a shorter survival time compared with those with normal levels (P=0.042). In conclusion, age is one of the major prognostic factors affecting survival in lung cancer patients; therefore, patients should be managed according to age in clinical practice.

INTRODUCTION Few data are available about primary lung cancer in the Caribbean. The purpose of this study was to provide, for the first time, the epidemiological and clinical characteristics of primary lung cancer in the archipelago of Guadeloupe (French West Indies). METHODS From the cancer registry, we identified in this retrospective study, all incident cases of primary lung cancer that had occurred between 1st January 2008 and 31st December 2009 in Guadeloupe. RESULTS Over the period from 2008 to 2009, 106 patients with primary lung cancer were identified. Males accounted for 72.6% and the women for 27.4%. Mean incidence rate over the 2 years was estimated at 13.4/100000 persons-years (95% CI: [6.0-20.8]) in men (world standardized) and 4.2/100000 persons-years (95% CI: [0.3-8.1]) in women. The median age at initial diagnosis was 65 years for men and 66 years for women. We noted a proportion of 61.3% of current smokers, 4.7% of passive smokers and 34% of non-smokers. The comorbidities were present in 41% of patients. Non-small cell lung cancer (NSCLC) accounted for 88.7% of lung cancers and small cell lung cancer for 7.5%. The most common histological type was adenocarcinoma (43%) followed by squamous cell (24%). Stage III and IV patients accounted for 64.1% of individuals with NSCLC. CONCLUSION The incidence of primary lung cancer in Guadeloupe is relatively low compared to metropolitan France. Guadeloupe is also a French department where the rate of tobacco consumption is one of the lowest.
