Chemokines and Their Receptors: Predictors of Therapeutic Potential in Tumor Microenvironment on Esophageal Cancer.

Esophageal carcinoma (ESCA) is an aggressive solid tumor. The 5-year survival rate for patients with ESCA is estimated to be less than 20%, mainly due to tumor invasion and metastasis. Therefore, it is urgent to improve early diagnostic tools and effective treatments for ESCA patients.

miR-133b Promotes Esophageal Squamous Cell Carcinoma Metastasis.

Background: Evaluation of biological changes at the molecular level has important clinical implications for improving the survival rate of esophageal squamous cell carcinoma (ESCC). Therefore, we plan to analyze and elucidate the expression of microRNA-133b (miR-133b), M2 pyruvate kinase (PKM2), and signal transducer and activator of transcription 3 (STAT3) in ESCC and their associated clinicopathological significance.

Methods: The 72 patients with ESCC were selected as the experimental study group.

A new isoflavone from the stems of How.

A preliminary screening test was performed to discover new antihyperlipidaemic active compounds from the leguminous plant How. A new compound, derris-isoflavone F (), and derrubone dimethyl ether (), a known synthetic compound of natural origin, were isolated from the stems of alongside eight recognised compounds. To our knowledge, this is the first instance of documenting the identification of compounds - from this plant.

Dual-energy spectral detector computed tomography differential diagnosis of adrenal adenoma and pheochromocytoma: Changes in the energy level curve, a phenomenon caused by lipid components?

Background And Objectives: Pheochromocytoma and adrenal adenoma are common space-occupying lesions of the adrenal gland, and incorrect surgery may lead to adrenal crisis. We used a new method, dual-energy spectral detector computed tomography (SDCT), to differentiate between the two.

Materials And Methods: We analysed the imaging images of patients with SDCT scans and pathologically confirmed adrenal adenomas (n=70) and pheochromocytomas (n=15).

Promotion of Lung Cancer Metastasis by SIRT2-Mediated Extracellular Protein Deacetylation.

Acetylation of extracellular proteins has been observed in many independent studies where particular attention has been given to the dynamic change of the microenvironmental protein post-translational modifications. While extracellular proteins can be acetylated within the cells prior to their micro-environmental distribution, their deacetylation in a tumor microenvironment remains elusive. Here it is described that multiple acetyl-vWA domain-carrying proteins including integrin β3 (ITGB3) and collagen 6A (COL6A) are deacetylated by Sirtuin family member SIRT2 in extracellular space.

Acetylation licenses Th1 cell polarization to constrain Listeria monocytogenes infection.

T helper 1 (Th1) immunity is typically viewed as a critical adaptation by vertebrates against intracellular pathogens. Identifying novel targets to enhance Th1 cell differentiation and function is increasingly important for anti-infection immunity. Here, through small-molecule screening focusing on epigenetic modifiers during the in vitro Th1 cell differentiation process, we identified that the selective histone deacetylase 6 (HDAC6) inhibitors ricolinostat and nexturastat A (Nex A) promoted Th1 cell differentiation.

A high-fat diet induces obesity and impairs bone acquisition in young male mice.

The postnatal development of obesity is highly associated with the excessive consumption of a high-calorie, high-fat diet (HFD). However, the correlation between HFD-induced pediatric obesity and skeletal development remains to be elucidated. In the present study, postnatal day 17 (PND17) mice were weaned on a HFD for eight weeks ad libitum to induce obesity.

A modified triple incision technique for women with locally advanced vulvar cancer: a description of the technique and outcomes.

Objective: Women with locally advanced vulvar carcinoma have an excellent chance of a cure by undergoing a radical vulvectomy with an "en bloc" inguinofemoral lymphadenectomy, but the morbidity associated this surgical approach is substantial. To achieve an outcome comparable with the traditional radical method in terms of oncologic safety, and an improved post-operative quality of life, we modified the classic triple-incision technique and suggested it as an alternative for these patients. The aim of this study was to report this new technique.

An effective and safe supplement for stem cells expansion ex vivo: cord blood serum.

Mesenchymal stem cells (MSCs) are potential and optimal stem cells in clinical cell therapy, and fetal bovine serum (FBS) is widely used for expansion of MSCs, despite the risks of infectious disease transmission and immunological reaction of the xenogenic origin. This study was designed to compare human four blood group cord blood serum (CBS) with FBS in culturing human placenta-derived mesenchymal stem cells (hPDMSCs), which were derived from four blood group donors. The expansion medium included: 10% FBS, 10% A-CBS, 10% B-CBS, 10% O-CBS, and 10% AB-CBS.

The status of phosphorylated p38 in esophageal squamous cell carcinoma.

The p38 mitogen-activated protein kinase (MAPK) is a member of the MAPK family, which is initially found to be activated by stress stimuli, proinflammatory cytokines, and growth factors. However, its role in the pathogenesis of esophageal squamous cell carcinoma (ESCC) is largely unkown, so we investigate the role of phosphorylated p38 (p-p38) MAPK in ESCC. First of all, in vitro cell line ECa109, SB203580 as selective inhibitor of p38, can suppress the growth of esophageal cancer cell in a dose- and time-dependent way, suggesting that ECa109 cell growth and proliferation was closely associated with p-p38.

Northwestern China: a place to learn more on oesophageal cancer. Part two: gene alterations and polymorphisms.

In the first part of this review, some behavioural and environmental risk factors playing important roles in the development of Kazakh's oesophageal squamous cell carcinoma (OSCC) were presented. Although all individuals have been exposed to the same environment and share the same behaviour, some of them will not develop OSCC. Thus, gene susceptibility and/or gene polymorphism are unavoidably involved.

[Expression of ERK1/2 MAPK signaling transduction pathway in esophageal cancers in Kazakh patients].

Objective: To investigate the expression variation and significance of ERK1/2 MAPK signaling transduction pathway in the pathogenesis of esophageal squamous cell carcinoma (ESCC) in Kazakh patients.
