A CpG Methylation Classifier to Predict Relapse in Adults with T-Cell Lymphoblastic Lymphoma.

Purpose: Adults with T-cell lymphoblastic lymphoma (T-LBL) generally benefit from treatment with acute lymphoblastic leukemia (ALL)-like regimens, but approximately 40% will relapse after such treatment. We evaluated the value of CpG methylation in predicting relapse for adults with T-LBL treated with ALL-like regimens.

Experimental Design: A total of 549 adults with T-LBL from 27 medical centers were included in the analysis.

LncRNA CASC9 Suppressed the Apoptosis of Gastric Cancer Cells through Regulating BMI1.

Long noncoding RNAs (lncRNAs) play important roles in regulating the apoptosis of gastric cancer (GC) cells. This study aims to investigate the underlying mechanism of lncRNA CASC9 in regulating the apoptosis of GC cells. The expressions of lncRNA and protein in GC tissues and cell lines were detected by qRT-PCR and western blot.

Prognostic and predictive value of a microRNA signature in adults with T-cell lymphoblastic lymphoma.

New prognostic factors are needed to establish indications for haematopoietic stem cell transplantation (HSCT) in first complete remission (CR1) for T-cell lymphoblastic lymphoma (T-LBL) patients. We used microarray to compare T-LBL tissue samples (n = 75) and fetal thymus tissues (n = 20), and identified 35 differentially expressed miRNAs. Using 107 subjects as the training group, we developed a five-miRNA-based classifier to predict patient survival with LASSO Cox regression: lower risk was associated with better prognosis (disease-free survival (DFS): hazard ratio (HR) 4.

Curative Effect of Digestive Tract Reconstruction After Radical Gastrectomy for Distal Gastric Cancer.

Objective: Short-term complications and long-term prognoses of three kinds of digestive tract reconstructions after radical gastrectomy for distal gastric cancer were compared.

Materials And Methods: Patients who underwent radical gastrectomy for distal gastric cancer were divided into three groups according to the type of digestive tract reconstruction: Billroth I, Billroth II, and Roux-en-Y anastomosis. Clinicopathological characteristics, intraoperative conditions, short-term complications, and long-term prognoses were compared among the three groups.

Wedelolactone inhibits osteoclastogenesis but enhances osteoblastogenesis through altering different semaphorins production.

Our previous study showed that wedelolactone, isolated from Ecliptae herba, enhanced osteoblastogenesis but inhibited osteoclastogenesis through Sema3A signaling pathway. This study aims to investigate the role of other semaphorins in wedelolactone-enhanced osteoblastogenesis and -inhibited osteoclastogenesis. Wedelolactone inhibited RANKL-induced Sema4D and Sema7A production, but had no effect on RANKL-reduced Sema6D expression in osteoclastic RAW264.

Long Noncoding RNA PVT1 Acts as a "Sponge" to Inhibit microRNA-152 in Gastric Cancer Cells.

Background: PVT1 was up-regulated in patients with gastric cancer (GC) and might be as a novel biomarker for predicting GC. However, the exact mechanism of PVT1 exerting functions in GC was still poorly understood. Emerging evidence suggests that long noncoding RNAs may act as endogenous microRNA (miRNA) sponges to bind to miRNAs and regulate their function.

A critical analysis of the relationship between aldehyde dehydrogenases-2 Glu487Lys polymorphism and colorectal cancer susceptibility.

Studies investigating the association between genetic polymorphism of aldehyde dehydrogenases-2 (ALDH-2) Glu487Lys and colorectal cancer (CRC) risk have reported conflicting results. Given this uncertainty, we carried out a critical analysis of published case-control studies to derive a more precise estimation of this relationship. Published literature from PubMed, EMBASE and China Knowledge Resource Integrated Database were retrieved, and the literature search was updated in June 2014.

Clinical significance of autophagic protein LC3 levels and its correlation with XIAP expression in hepatocellular carcinoma.

Autophagy is a cellular recycling process to enable cell survival in less favorable conditions through degradation of their unnecessary cellular components and utilization of the breakdown components. Autophagy also plays an important role in tumor pathology. In this study, we detected autophagy protein light chain 3 (LC3) and X-linked inhibitor of apoptosis protein (XIAP) in hepatocellular carcinoma (HCC) tissue specimens to assess their role in HCC tumorigenesis and progression.

Loss of suppressors of cytokine signaling 3 promotes aggressiveness in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common cancers with a high mortality rate. Constitutive activation of STAT3 is found in various types of tumors, including HCC. In addition, suppressors of cytokine signaling 3 (SOCS3) signals for negative feedback to STATs, and is found to be inversely correlated with STAT3 expression.

MDM2 SNP309 is an ethnicity-dependent risk factor for digestive tract cancers.

Published data on the relationship between T309G polymorphism in the murine double minute 2 (MDM2) gene and susceptibility of digestive tract cancers (DTC) are inconclusive. Thus, the aim of this study is to determine whether MDM2 T309G polymorphism is associated with the risk of diverse DTC, including esophagus, stomach, liver, bile duct, pancreas, and colorectum cancers. Relevant studies were identified up to October 1, 2013.

[Clinical features and therapeutic strategies of acute appendicitis after radical gastrectomy for gastric carcinoma].

Objective: To explore the clinical characteristic and therapeutic strategies of acute appendicitis after radical gastrectomy for gastric carcinoma.

Methods: The clinical data of 31 patients with acute appendicitis after radical gastrectomy for gastric carcinoma from January 2006 to January 2012 was analyzed retrospectively. The profiles of previous operations, symptoms, physical signs, disease duration, progression time, examination results, peri-operative complications, results of bacterial culture and use of antibiotics were used to evaluate the clinical characteristics and therapeutic strategies.

Formaldehyde up-regulates TRPV1 through MAPK and PI3K signaling pathways in a rat model of bone cancer pain.

Objective: Our previous study showed that tumor tissue-derived formaldehyde at low concentrations plays an important role in bone cancer pain through activating transient receptor potential vanilloid subfamily member 1 (TRPV1). The present study further explored whether this tumor tissue-derived endogenous formaldehyde regulates TRPV1 expression in a rat model of bone cancer pain, and if so, what the possible signal pathways are during the development of this type of pain.

Methods: A rat model of bone cancer pain was established by injecting living MRMT-1 tumor cells into the tibia.

STAT3 activation in monocytes accelerates liver cancer progression.

Background: Signal transducer and activator of transcription 3 (STAT3) is an important transcription factor ubiquitously expressed in different cell types. STAT3 plays an essential role in cell survival, proliferation, and differentiation. Aberrantly hyper-activated STAT3 signaling in cancer cells and in the tumor microenvironment has been detected in a wide variety of human cancers and is considered an important factor for cancer initiation, development, and progression.

Activation of satellite glial cells in lumbar dorsal root ganglia contributes to neuropathic pain after spinal nerve ligation.

The role of satellite glial cells (SGCs) of sensory ganglia in chronic pain begins to receive interest. The present study aims to investigate the contribution of SGC activation to the development of neuropathic pain. A neuropathic pain model was established by lumbar 5 spinal nerve ligation (SNL), and glial fibrillary acidic protein (GFAP) was used as a marker of SGC activation.

Prognostic significance of phosphorylated signal transducer and activator of transcription 3 and suppressor of cytokine signaling 3 expression in hepatocellular carcinoma.

Altered expression of phosphorylated signal transducer and activator of transcription 3 (pSTAT3) and suppressor of cytokine signaling 3 (SOCS3) has been implicated in various types of human cancers. However, the clinical role of pSTAT3 and SOCS3 in hepatocellular carcinoma (HCC) is not well established. Immunohistochemical analysis of pSTAT3, SOCS3, Ki67 and VEGF expression was performed on tissue microarrays from 138 HCC patients.
