Multiple Interactions

AbstractLung cancer is one of the most prevalent malignancies worldwide. Local recurrence and distant metastasis remain the major causes of treatment failure. It has been recognized that the process of tumor growth and metastasis involves multiple interactions between tumor and host. Various biomarkers have been used for predicting tumor recurrence, metastasis, and prognosis in patients with lung cancer. However, these biomarkers are still controversial and require further validation. The relationship between malignancy and coagulation system disorders has been explored for more than a century. Fibrinogen is the most abundant plasma coagulation factor synthesized mainly by hepatic cells. Increased plasma fibrinogen levels were observed in various carcinomas such as gastric cancer, colon cancer, and pancreatic cancer. Recent studies have also investigated the role of fibrinogen in patients with lung cancer. This review aimed to address the role of fibrinogen in lung cancer.

Abstract Background Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer death worldwide. Lung adenocarcinoma (LUAD) is the most common type of lung cancer. Transducin-like Enhancer of split (TLE) family proteins repress transcription by multiple mechanisms. The prognostic role of TLEs in LUAD is still unclear. Methods We took TCGA dataset to analyze the relationship between the expression of TLEs and LUAD outcome. Results The expression of TLEs were different between 59 normal and 513 tumor samples. High TLE1 and low TLE2 were associated with poor PFS and OS (all p＜0.050). Multivariate analysis demonstrated that high TLE1 and low TLE2 were independent risk factors. Moreover, the combination of TLE1 and TLE2 was a better tool in prognostication. Conclusions High TLE1 and low TLE2 expressions are independent adverse prognostic factors and can be used as prognostic biomarkers in LUAD.

Knowledge of the patterns of symptom distress in adults receiving treatment for lung cancer is an important first step in developing interventions that can potentially lessen symptom distress. The purposes of this secondary analysis were to describe the changes in patterns of symptom distress over time in adults receiving treatment for lung cancer, and to examine the relationship of selected demographic and clinical characteristics to symptom distress. Complete data were available for 117 patients. The patterns of symptom distress in adults receiving treatment for lung cancer varied between treatment groups and over time. Symptom distress scores were moderate to high on entry into the study, indicating that symptom management in newly diagnosed lung cancer patients is essential and should begin early in the course of illness. Moreover, clinical interventions should be tailored to the type of treatment. Various demographic and clinical variables were weak and inconsistent predictors of symptom distress, underscoring the importance of examining the role of psychosocial factors in mediating symptom distress.

BACKGROUND: Recent studies have shown that microRNAs (miRNA) have prognostic values in cancers. This meta-analysis seeks to summarize the global predicting role of miR-155 for survival in patients with a variety of carcinomas.METHODS: Eligible studies were identified through multiple search strategies. Data were extracted from studies investigating the relationship between miR-155 expression and survival in cancer patients. Combined hazard ratios (HRs) of miR-155 for outcome were analyzed.RESULTS: A total of 16 studies dealing with various carcinomas were included for this meta-analysis. For overall survival, higher miR-155 expression could significantly predict worse outcome with the pooled HR of 2.057 (95% CI: 1.392–3.039). For relapse or progress-free survival, elevated miR-155 was also a significant predictor, with a combined HR of 1.918 (95% CI: 1.311–2.806,). In addition, subgroup analysis showed that higher expression of miR-155 had the trends to predict worse outcome in lung cancer. However, the HRs did not reach the statistical significance.CONCLUSION: Our findings suggest that miR-155 detection has a prognostic value in cancer patients. Regularly measuring miR-155 expression may be useful in clinical practice.

Mechanical Stretching

Cells and tissues in the human body are subjected to mechanical forces of varying degrees, such as tension or pressure. During tumorigenesis, physical factors, especially mechanical factors, are involved in tumor development. As lung tissue is influenced by movements associated with breathing, it is constantly subjected to cyclical stretching and retraction; therefore, lung cancer cells and lung cancer-associated fibroblasts (CAFs) are constantly exposed to mechanical load. Thus, to better explore the mechanisms involved in lung cancer progression, it is necessary to consider factors involved in cell mechanics, which may provide a more comprehensive analysis of tumorigenesis. The purpose of this review is: 1) to provide an overview of the anatomy and tissue characteristics of the lung and the presence of mechanical stimulation; 2) to summarize the role of mechanical stretching in the progression of lung cancer; and 3) to describe the relationship between mechanical stretching and the lung cancer microenvironment, especially CAFs.

SummaryThe effects of 2 intraperitoneal injections of the alkylating agent Busulphan (each of 25 mg/kg body weight, 3 days between injections) on the circulating elements of the blood and on the plasma coagulation system in rabbits have been investigated.Platelets fell progressively after a lag-phase of 7 days, reached a mean minimum level of about 3 % of the pre-injection level in 14 days, and then returned slowly towards normal values. Bleeding was an occasional complication and a rare cause of death. Granulocytopenia developed synchronously with the fall in platelets. The plasma clotting factors remained intact.We conclude that this is a useful experimental model for studies on the role of platelets in hemostasis and thrombosis.

Cancer Associated Thrombosis

AbstractPathological activation of the coagulation system occurs with virtually all forms of cancer, particularly epithelial malignancies. Accordingly, thrombosis is one of the most common comorbidities associated with cancer. Indeed, cancer-associated thromboembolism is the second leading cause of death for cancer patients, second only to the cancer itself. The identification of specific molecular mechanisms whereby tumor cells activate the coagulation system and drive thrombosis has been an active area of investigation for several decades. Studies in animal models and human trials have revealed that there is a bidirectional relationship between coagulation factor activity and cancer, whereby the pathological hemostatic system activation associated with cancer not only promotes thromboembolism but also drives progression of the malignancy. Numerous studies indicate that factors up and down the clotting cascade can contribute to various stages of cancer, including tumorigenesis, primary tumor growth, and metastasis. Although there are some mechanistic points of commonality, there are also clearly context-dependent contributions of coagulation components to cancer progression dependent on the type of cancer and stage of disease. It is also notable that in some instances, coagulation factors appear to contribute to cancer progression independently of their traditional roles in hemostasis and thrombosis. Here, the authors review the current state of the field with regard to hemostatic factor-driven cancer pathogenesis.

AimsTo unveil the role of EI2BL in non-small cell lung cancer (NSCLC) and the relationship between expression of EI2BL and the prognosis of patients with NSCLC.MethodsImmunohistochemistry (IHC), western blot analysis, immunofluorescence and real-time quantitative PCR (RT-qPCR) were used to evaluate EI2BL protein and mRNA levels in NSCLC and corresponding peritumour tissues. Cell Counting Kit-8, transwell assay and wound healing assay were used to analyse the abilities of cell proliferation, invasion and migration. In addition, the analysis of epithelial-mesenchymal transition (EMT) markers was also assessed by western blot analysis, RT-qPCR and immunofluorescence. Tissue micro-array analysis of 200 NSCLC cases was used to assess the relationship between EI2BL expression and clinicopathological characteristics. Moreover, the prognostic role of EI2BL in 200 patients with NSCLC was evaluated by Cox regression models and Kaplan-Meier methods.ResultsElevated EI2BL expression was more common in NSCLC tissues than paired peritumour tissues in both mRNA and protein level. EI2BL promoted the proliferation, invasion and migration of NSCLC cells. In addition, aberrant EI2BL expression might modulate the expression of key molecules of EMT by ERK1/2 signal pathway. The expression of EI2BL was significantly associated with tumour stage, lymph node metastasis and tumour size. Moreover, higher expression of EI2BL in patients with NSCLC had a poor overall survival rate.ConclusionsOur study illustrated that elevated expression of EI2BL promoted NSCLC cell proliferation, migration and invasion and EI2BL overexpression may be a reliable biomarker of poor prognosis.
