Spinal Lymphatic Dysfunction Aggravates the Recovery Process After Spinal Cord Injury.

We aimed to evaluate the role of the spinal lymphatic system in spinal cord injury and whether it has an impact on recovery after spinal cord injury. Flow cytometry was used to evaluate the changes in the number of microvesicles after spinal cord injury. Evans blue extravasation was used to evaluate the function of the lymphatic system.

F-FDG PET/CT SUV and serum CEA levels as predictors for EGFR mutation state in Chinese patients with non-small cell lung cancer.

The epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) contribute to an increased response rate, compared with chemotherapy, in patients with inhibitor-sensitive EGFR mutations. The present study evaluated the association between the maximum standardized uptake value (SUV) of F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT), as well as serum carcinoembryonic antigen (CEA) levels and EGFR mutations prior to treatment, in patients with non-small cell lung cancer (NSCLC). Patients with histologically confirmed NSCLC (n=167), who underwent an F-FDG PET/CT scan, EGFR mutation analysis and a serum CEA test participated in the present study.

Shenqi Fuzheng Injection Ameliorates Radiation-induced Brain Injury.

Shenqi Fuzheng injection (SFI) has been confirmed to be able to alleviate brain injury in mice. This study examined the brain-protective effect of SFI on patients after cranial radiation. Lung cancer patients with brain metastasis were randomly assigned to two groups.

Catecholamines contribute to the neovascularization of lung cancer via tumor-associated macrophages.

Purpose: Elevated catecholamines in the tumor microenvironment often correlate with tumor development. However, the mechanisms by which catecholamines modulate lung cancer growth are still poorly understood. This study is aimed at examining the functions and mechanisms of catecholamine-induced macrophage polarization in angiogenesis and tumor development.

The role of sema4D in vasculogenic mimicry formation in non-small cell lung cancer and the underlying mechanisms.

Vasculogenic mimicry (VM) is a special vascular pattern in malignant tumors, which is composed of highly aggressive tumor cells. This tumor cell-mediated blood supply pattern is closely associated with a poor prognosis in cancer patients. The interaction of axon guidance factor Sema4D and its high affinity receptor plexinB1 could activate small GTPase RhoA and its downstream ROCKs; this process has an active role in the migration of endothelial cells and tumor angiogenesis.

Correction to: MicroRNA-330-3p promotes cell invasion and metastasis in non-small cell lung cancer through GRIA3 by activating MAPK/ERK signaling pathway.

The original article [1] contained incorrect affiliations for the authors.

MicroRNA-330-3p promotes cell invasion and metastasis in non-small cell lung cancer through GRIA3 by activating MAPK/ERK signaling pathway.

Background: Brain metastasis (BM) is associated with poor prognosis in patients with non-small cell lung cancer (NSCLC). Recent studies demonstrated that microRNA-330-3p (miR-330-3p) was involved in NSCLC brain metastasis (BM). However, the exact parts played by miR-330-3p in BM of NSCLC remain unknown.

Clinical features and prognostic factors of small cell lung cancer: A retrospective study in 148 patients.

To better understand the outcomes of small cell lung cancer (SCLC), we examined the clinical features and prognostic factors of SCLC in this study. A total of 148 patients who were diagnosed as having SCLC between January 2009 and December 2013 in Cancer Center of Union Hospital, Wuhan, China, were enrolled and their clinical features and prognostic factors were retrospectively analyzed. Log-rank test and Cox regression model were employed for analysis of prognostic factors.

JNK in spinal cord facilitates bone cancer pain in rats through modulation of CXCL1.

In patients with advanced cancer, cancer-induced bone pain (CIBP) is a severe and common problem that is difficult to manage and explain. As c-Jun N-terminal kinase (JNK) and chemokine (C-X-C motif) ligand 1 (CXCL1) have been shown to participate in several chronic pain processes, we investigated the role of JNK and CXCL1 in CIBP and the relationship between them. A rat bone cancer pain model was established by intramedullary injection of Walker 256 rat gland mammary carcinoma cells into the left tibia of Sprague-Dawley rats.

Rho Kinase Inhibitor Fasudil Suppresses the Vasculogenic Mimicry of B16 Mouse Melanoma Cells Both In Vitro and In Vivo.

The aim of this study was to investigate the biologic role of the Rho kinase inhibitor fasudil in the vasculogenic mimicry (VM) of B16 mouse melanoma cells. It was previously reported that RhoA plays a critical role in angiogenesis by coordinating endothelial cell cytoskeleton remodeling and promoting endothelial cell motility. Although RhoA has been implicated in the regulation of angiogenesis, little has been described regarding its control of these tumor cell-lined channels.

Radiosensitivity enhancement of human hepatocellular carcinoma cell line SMMC-7721 by sorafenib through the MEK/ERK signal pathway.

Purpose: Sorafenib, an oral multikinase inhibitor, is the first agent that has demonstrated an improved overall survival benefit in advanced hepatocellular carcinoma, setting a new standard for first-line treatment. However, the association between radiosensitivity and sorafenib remains unclear. The purpose of this study was to investigate whether sorafenib could enhance radiosensitivity and the possible mechanisms of sorafenib-mediated radiosensitization in human hepatocellular carcinoma cell line SMMC-7721.

[Effects of GM3 on proliferation, apoptosis and VEGF expression in human lung adenocarcinoma cell line A549 cells].

Objective: To determine the effect of exogenous GM3 on proliferation, apoptosis and VEGF expression in human lung adenocarcinoma cell line A549 cells.

Methods: A549 cells were treated with GM3 at different concentrations for 48 hours. MTT assay was used to detect the cell proliferation and flow cytometry was applied to analyze cell apoptosis.

Sp1 inhibition-mediated upregulation of VEGF 165 b induced by rh-endostatin enhances antiangiogenic and anticancer effect of rh-endostatin in A549.

Recombinant human endostatin (rh-endostatin), a potential antiangiogenic agent, is used in non-small cell lung carcinoma treatment and represses vascular endothelial cell growth factor (VEGF) levels in tumor cell. However, precise affection of rh-endostatin on the proangiogenic VEGF isoforms (VEGF(165)) or antiangiogenic VEGF isoforms (VEGF(165)b) is not clear. We therefore tested the hypothesis that rh-endostatin could alter expression of these isoforms to regulate tumor growth.

Expression of CDK5/p35 in resected patients with non-small cell lung cancer: relation to prognosis.

Overall outcome of those patients with non-small cell lung cancer (NSCLC) remains poor. Recently, several studies demonstrated that cyclin-dependent kinase-5 (CDK5) activity with its specific activator protein p35 was important for spontaneous metastasis in various types of carcinomas. Our objective was to explore the expression of CDK5 and its prognostic indicator in patients with NSCLC.

Acquired cisplatin resistance in human lung adenocarcinoma cells is associated with enhanced autophagy.

Activation of autophagy is a hallmark in tumor cells treated with chemotherapy, but the role of autophagy in acquired resistance of lung adenocarcinoma to cisplatin-based chemotherapy remains to be clarified. Our aim was to address that question by surveying the autophagic activity in parental lung adenocarcinoma cell line A549 and its 8-fold, more resistant subcell line, A549/DDP, which was obtained by treating cisplatin with increasing concentrations. A549/DDP and A549 cells were exposed to serum-free culture medium or ionizing radiation.
