miR-466 Contributes to the Enhanced Antitumor Effect of Bortezomib on Non-Small-Cell Lung Cancer by Inhibiting CCND1.

Introduction: Changes in microRNAs (miRs) contribute to the alternative chemo-resistance of cancers. Bortezomib (BTZ) is a well-characterized anticancer agent that inhibits proteasome, and its effect is associated with the function of miRs. Based on the data of microarray assay and comprehensive bioinformatics analyses, in the current study, we explored the role of miR-466 and its downstream effector CCND1 in the BTZ-resistance of non-small-cell lung cancer (NSCLC) cells.

Enhancement of E-cadherin expression and processing and driving of cancer cell metastasis by ARID1A deficiency.

The ARID1A gene, which encodes a subunit of the SWI/SNF chromatin remodeling complex, has been found to be frequently mutated in many human cancer types. However, the function and mechanism of ARID1A in cancer metastasis are still unclear. Here, we show that knockdown of ARID1A increases the ability of breast cancer cells to proliferate, migrate, invade, and metastasize in vivo.

Downregulation of PDGF-D Inhibits Proliferation and Invasion in Breast Cancer MDA-MB-231 Cells.

Background: The platelet derived growth factor-D (PDGF-D) plays an important role in breast tumor aggressiveness. However, limited study has investigated the effect of silencing PDGF-D on the biological function of breast cancer. The purpose of this study is to clarify the potential value of PDGF-D as a target for breast cancer treatment.

Genomic and Transcriptomic Characterization of Sporadic Medullary Thyroid Carcinoma.

Sporadic medullary thyroid carcinoma (MTC) is a relatively uncommon neuroendocrine malignancy and the molecular tumorigenesis of its sporadic type (sMTC) is only partially understood. In this study, we performed a study focusing on the genomic and transcriptomic characterization of sMTC. Twenty-nine sMTC patients were included.

miR-27a-3p regulates proliferation and apoptosis of colon cancer cells by potentially targeting BTG1.

microRNA (miR/miRNA)-27a-3p has been reported to be abnormally expressed in various types of cancer, including colorectal cancer (CRC). B-cell translocation gene 1 (BTG1) has also been implicated with CRC. However, the association between miR-27a-3p and BTG1 in CRC, to the best of our knowledge, has not been investigated.

Role of the brain-gut axis in gastrointestinal cancer.

Several studies have largely focused on the significant role of the nervous and immune systems in the process of tumorigenesis, including tumor growth, proliferation, apoptosis, and metastasis. The brain-gut-axis is a new paradigm in neuroscience, which describes the biochemical signaling between the gastrointestinal (GI) tract and the central nervous system. This axis may play a critical role in the tumorigenesis and development of GI cancers.

A novel fluorescein-based "turn-on" probe for the detection of hydrazine and its application in living cells.

We constructed a novel probe for hydrazine detection based on ICT and PET mechanism. Phthalimide and acetyl ester groups were used as the recognition units. Addition of hydrazine produced a turn-on fluorescence at 525nm along with the fluorescent color change from dark to yellow.

The impact of high co-expression of Sp1 and HIF1α on prognosis of patients with hepatocellular cancer.

Transcription factor specificity protein 1 (Sp1) and hypoxia-inducible factor 1α (HIF1α) serve vital roles in tumor growth and metastasis. The present study aimed to evaluate the impact of co-expression of Sp1 and HIF1α on the prognosis of patients with hepatocellular cancer (HCC) using The Cancer Genome Atlas (TCGA) database and to validate the association between the expression levels of Sp1/HIF1α in HCC specimens and patient survival using immunohistochemical analysis. A total of 214 eligible patients with HCC from TCGA database were collected for the study.

Diagnostic value of contrast-enhanced ultrasound in papillary thyroid microcarcinoma.

The aim of the present study was to explore the value and characteristics of contrast-enhanced ultrasound (CEUS) in the diagnosis of papillary thyroid microcarcinoma (PTMC). By analyzing CEUS information of 130 nodules obtained from 106 patients with PTMC, who had been diagnosed by surgery and pathological analysis, CEUS characteristics of PTMC nodules were concluded. Based on the results, the PTMC nodules were divided into three groups as follows: 32 nodules (24.

Effectiveness of Mindfulness-based Therapy for Reducing Anxiety and Depression in Patients With Cancer: A Meta-analysis.

Anxiety and depression are common among patients with cancer, and are often treated with psychological interventions including mindfulness-based therapy.The aim of the study was to perform a meta-analysis of the effectiveness of mindfulness-based interventions for improving anxiety and depression in patients with cancer.Medline, the Cochrane Library, EMBASE, and Google Scholar were searched.

Proinflammatory effects and molecular mechanisms of interleukin-17 in intestinal epithelial cell line HT-29.

Aim: To evaluate the proinflammatory effects and molecular mechanisms of interleukin (IL)-17 in intestinal epithelial cell line HT-29.

Methods: HT-29 cells were cultured with IL-17, tumor necrosis factor (TNF)-α, or the combination of both IL-17 and TNF-α. Real-time PCR and Western blot were used to measure the gene expression levels of neutrophil chemokines CXCL1, CXCL2, CXCL5, CXCL6, IL-8 and TH-17 cell chemokine CCL20, the phosphorylation levels of p38 and TNF-α, and the expression level of IL-8, after using the p38 inhibitor in HT-29 cells.

The influence of demographics, psychological factors and self-efficacy on symptom distress in colorectal cancer patients undergoing post-surgical adjuvant chemotherapy.

Purpose: To explore the influence of self-efficacy and demographic, disease-related, and psychological factors on symptom distress among Chinese colorectal cancer patients receiving postoperative adjuvant chemotherapy.

Methods: Two-hundred and fifty-two colorectal cancer patients who had undergone postoperative adjuvant chemotherapy completed Chinese versions of M. D.

[Expression and significance of Rab5a and APPL1 in breast cancer].

Objective: To investigate the expression of Rab5a and APPL1 in breast cancer and fibroma, and analyze their correlation with HER-2 expression, metastasis and development of breast cancer.

Methods: Rab5a and APPL1 in paraffin embedded tissues of 74 breast carcinomas and 40 breast fibromas were detected by immunohistochemistry. Their relationship with metastasis, pathological grade, and HER-2 expression in breast cancer was determined by statistical analysis.
