Analysis of microarrays of miR-34a and its identification of prospective target gene signature in hepatocellular carcinoma.

Background: Currently, some studies have demonstrated that miR-34a could serve as a suppressor of several cancers including hepatocellular carcinoma (HCC). Previously, we discovered that miR-34a was downregulated in HCC and involved in the tumorigenesis and progression of HCC; however, the mechanism remains unclear. The purpose of this study was to estimate the expression of miR-34a in HCC by applying the microarray profiles and analyzing the predicted targets of miR-34a and their related biological pathways of HCC.

Quantitative Analysis of Hepatic Microcirculation in Rabbits After Liver Ischemia-Reperfusion Injury Using Contrast-Enhanced Ultrasound.

Previous studies have shown that contrast-enhanced ultrasound (CEUS) can be used quantitatively to analyze microcirculation blood perfusion in hepatocellular carcinoma patients. However, limited data have described the application of CEUS in hepatic microcirculation after liver ischemic-reperfusion injury (IRI). The purpose of this study was to explore the use of CEUS quantitatively to assess liver microcirculation after liver IRI.

Expression of IL-22 in the Skin Causes Th2-Biased Immunity, Epidermal Barrier Dysfunction, and Pruritus via Stimulating Epithelial Th2 Cytokines and the GRP Pathway.

Increased expression of Th22 cytokine IL-22 is a characteristic finding in atopic dermatitis (AD). However, the specific role of IL-22 in the pathogenesis of AD in vivo has yet to be elucidated. Consistent with observations in human AD, IL-22 was significantly increased in the AD skin of mice after epicutaneous sensitization to house dust mite allergen.

AKT activation was not essential for hepatocellular carcinoma cell survival under glucose deprivation.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide, with a dismal 5-year survival rate less than 15%. The present study aimed to investigate whether AKT inhibition and glucose deprivation could synergistically kill HCC cells and the molecular mechanisms involved. HCC cells were starved in glucose deprivation, and then the resultant cell death was determined by flow cytometry and mitochondrial oxygen consumption rates using a Seahorse XF-24 Extracellular Flux Analyzer.

Relationship between TRAF6 and deterioration of HCC: an immunohistochemical and in vitro study.

Objective: To explore the relationship between tumor necrosis factor receptor-associated factor 6 (TRAF6) and the clinicopathological features in HCC as well as its biological function.

Methods: Totally, 412 liver tissues were collected, including 171 hepatocellular carcinoma (HCC) and their corresponding non-tumor tissues, 37 cirrhosis and 33 normal liver tissues. The expression of TRAF6 was assessed by immunohistochemistry.

TRPA1-dependent pruritus in IL-13-induced chronic atopic dermatitis.

Chronic debilitating pruritus is a cardinal feature of atopic dermatitis (AD). Little is known about the underlying mechanisms. Antihistamines lack efficacy in treating itch in AD, suggesting the existence of histamine-independent itch pathways in AD.

Up-regulation of heparan sulfate 6-O-sulfation in idiopathic pulmonary fibrosis.

Heparan sulfate proteoglycans (HSPGs) are integral components of the lung. Changes in HSPGs have been documented in idiopathic pulmonary fibrosis (IPF). Many of the biological functions of HSPGs are mediated by heparan sulfate (HS) side chains, and little is understood about these side chains in the pathogenesis of IPF.

Overexpression of Sulf2 in idiopathic pulmonary fibrosis.

Previously, we have shown that heparan sulfate (HS) 6-O-endosulfatase 1 (Sulf1) is a transforming growth factor-β1 (TGF-β1)-responsive gene in normal human lung fibroblasts and functions as a negative feedback regulator of TGF-β1 and that TGF-β1 induces the expression of Sulf1 as well as that of the closely related Sulf2 in a murine model of pulmonary fibrosis. In this study, we focused on the role of Sulf2 in modulating TGF-β1 function and the development of pulmonary fibrosis. We found that Sulf2 mRNA was overexpressed in lung samples from human patients with idiopathic pulmonary fibrosis (IPF), and Sulf2 protein was specifically localized to the hyperplastic type II alveolar epithelial cells (AECs).

Analysis of microRNA expression profiling identifies miR-155 and miR-155* as potential diagnostic markers for active tuberculosis: a preliminary study.

To explore biologic behaviors and disease relevance of microRNAs (miRNAs) in the development of active tuberculosis (ATB), we investigated the expression profile of Mycobacterium tuberculosis (MTB) purified protein derivative (PPD)-induced miRNAs to determine the specific miRNAs involved in the pathogenesis of ATB. The expression profile of miRNA under PPD challenge was first measured using microarray analysis in peripheral blood mononuclear cells isolated from ATB patients and healthy controls (HC). The remarkably reactive miRNAs were then validated in a larger cohort by quantitative real-time polymerase chain reaction (qRT-PCR).

Nasal administration of a novel recombinant human parathyroid hormone (1-34) analog for the treatment of osteoporosis of ovariectomized rats.

Synthetic human parathyroid (1-34) (hPTH (1-34)) is known to have the full biological activity of the holohormone for osteoporosis. This study is about designing a novel analog of hPTH (1-34) which is more suitable for intranasal administration. We likewise evaluate effectiveness of the nasal drops against osteoroporosis.

Biosynthesis of a novel recombinant peptide derived from hPTH(1-34).

A recombinant human parathyroid hormone fragment, Pro-Pro-[Arg(11)]hPTH(1-34)-Pro-Pro (MW=4550 Da), was developed by substituting Arg for Leu at position 11 and adding Pro-Pro at the carboxyl terminus. Following a single injection (0.5-13.

In vitro and in vivo activities of a new lead compound I2906 against Mycobacterium tuberculosis.

Background: Due to the long duration of treatment and the emergence of multidrug-resistant strains, new antitubercular agents are urgently needed. I2906, as a novel lead, was screened and tested for efficacy in vitro and in vivo.

Methods: To determine the efficacy of I2906,the minimum inhibitory concentrations against Mycobacterium tuberculosis and cytotoxicity were tested, and its in vivo activities were assessed by administering it to mice infected with M.
