Tumor suppressor BLU exerts growth inhibition by blocking ERK signaling and disrupting cell cycle progression through RAS pathway interference.

We have previously reported that the 3p21 tumor suppressor regulates cell cycle by blocking JNK/MAPK signaling. Another member of the MAPK family, extracellular signal response kinase (ERK), is induced by the RAS-RAF-MEK-ERK pathway and is targeted in anticancer therapy. The effects of on tumor growth were evaluated by measuring the size of nasopharyngeal carcinoma (NPC) xenografted tumors intra-tumorally injected with adenovirus 5 ( Ad5) and the viability of NPC cells transferred with .

Elevated circulating miR-126-3p expression in patients with acute myocardial infarction: its diagnostic value.

Acute myocardial infarction (AMI) therapy has not remarkably improved due to delay in the diagnosis to a great extent. Circulating microRNAs have shown some potential for diagnosis of cardiovascular diseases. The aim of this study was to estimate the diagnostic value of circulating miR-126-3p for AMI.

Study of natural IgG antibodies against vascular endothelial growth factor receptor 1 in hepatocellular carcinoma.

Natural antibodies have been found to have anti-tumorigenic function. This study was designed to investigate whether natural IgG antibodies against vascular endothelial growth factor receptor 1 (VEGFR1) could suppress the growth of hepatocellular carcinoma (HCC) cells. Three HCC cell lines and A549 lung cancer cells were used for this study.

Small molecular peptide-ScFv αvβ3 conjugates specifically inhibit lung cancer cell growth and .

Integrin αvβ3 (ITG) is highly expressed in various cancers and is considered a major target for anti-angiogensis cancer therapy. The single chain fragment variable of which (ScFv αvβ3) has been reported to inhibit tumor growth both and . Here, we conjugated cdGIGPQc which can exclusively bind to NSCLC cells according to our previous study synthesized by SPPS with ScFv αvβ3 expressed in E.

Circulating low IL-23: IL-35 cytokine ratio promotes progression associated with poor prognosisin breast cancer.

The interleukin (IL)-12 family, composed of heterodimeric cytokines including IL-12 (formed by IL-12p35 and IL-12p40 subunits), IL-23 (formed by IL-23p19 and IL-12p40 subunits), IL-27 (formed by IL-27p28 and EBI3 subunits) and IL-35 (formed by IL-12p35 and EBI3 subunits), establishes a link between innate and adaptive immunity that involves different immune effector cells and cytokines to tumors. However, the role of IL-12 family in breast cancer (BC) progression and prognosis remains unclear. In the present study, we demonstrated evidence indicating that EBI3, IL-12p35 and IL-12p40 but not IL-23p19 or IL-27p28 were highly expressed in BC tissues, suggested that tumor derived EBI3, IL-12p35 and IL-12p40 were associated with tumor progression.

Further study of circulating IgG antibodies to CD25-derived peptide antigens in nonsmall cell lung cancer.

A recent study reported that circulating antibodies to CD25-derived peptide antigens were significantly higher in patients with nonsmall cell lung cancer (NSCLC) than control subjects. The present study was, thus, undertaken to replicate the initial finding with different sample sets. An in-house ELISA was applied to determine circulating IgG antibodies to linear peptide antigens derived from CD25.

Niflumic acid exhibits anti-tumor activity in nasopharyngeal carcinoma cells through affecting the expression of ERK1/2 and the activity of MMP2 and MMP9.

Niflumic acid (NFA) was known to inhibit cell proliferation or migration in several types of cancer. However, the function of NFA in human nasopharyngeal carcinoma (NPC) cells was not clarified. The proliferation of NPC cell line CNE-2Z cells with NFA treatment was detected using the cell counting kit-8 method and transwell assay was employed to assess the effect of NFA on the CNE-2Z cell migration and invasion.

The tumor protection effect of high-frequency administration of whole tumor cell vaccine and enhanced efficacy by the protein component from Agrocybe aegerita.

Whole tumor cell vaccines have been widely studied and elicits limited immune responses because of the poor immunogenicity. In the present study, we discovered that high-frequency administration of irradiated whole tumor cell vaccine triggered rejection of tumor cells (90% or 100% of the mice that were vaccinated with irradiated H22 cells or S180 respectively were protected), and provided cross-protection and long-term anti-tumor immunity in BALB/c mouse models. The antitumor activity required CD4+, CD8+ T cells and macrophage that was proved in the nude mice and cell depletion mouse models.

Association between glutathione S-transferases M1 and T1 gene polymorphisms and esophageal cancer prognosi.

Objective: To investigate the independent factors affecting the prognosis of patients after resection of esophageal cancer, and to inquire into the relationship between GSTM1, GSTT1 gene polymorphisms and esophageal cancer prognosis.

Methods: The clinical data of 273 patients with esophageal cancer were retrospectively analyzed. The patients were followed-up after their surgery, and the gene polymorphisms of GSTM1 and GSTT1 in each individual were detected by polymerase chain reaction (PCR).
