Apoptotic block in colon cancer cells may be rectified by lentivirus mediated overexpression of caspase-9

Price: €10,00

Background and aim : At present, the inhibition of apoptosis during pathogenesis of colorectal cancer is widely recognized while the role of caspase-9 in this process remains controversial. We aimed to investigate the differential expression of caspase-9 and evaluate the therapeutic potential of expression intervention in this study. Methods : We first examined the different expression of caspase- 9 in normal colon mucosa, adenoma and cancer, investigating the relationship between its expression and clinico-pathological characteristics. Secondly, overexpression of caspase-9 was established in colon cancer cell lines by lentivirus infection to study the changes in growth, proliferation and apoptosis. Results : Compared with normal colon mucosa, the expression of caspase-9 was higher in adenoma while lower in cancer both at mRNA and protein level (P ver, a non-apoptotic role of caspase-9 facilitating differentiation was also implied.

Interferon mono-therapy for symptomatic HCV-associated mixed cryoglobulinemia: meta-analysis of clinical studies

Price: €10,00

Abstract Objective : Mixed cryoglobulinemia (MC) is an important complication of hepatitis C virus (HCV) infection. Antiviral therapy is now an important approach for symptomatic HCV-MC ; some information exists on IFN mono-therapy for symptomatic HCVMC in the non-transplant setting, but its efficacy is still unclear. Methods : We evaluated efficacy and safety of mono-therapy with standard or pegylated interferon (IFN) for symptomatic HCV-associated MC in non-immunosuppressed individuals by performing a systematic review of the literature with a meta-analysis of clinical studies. We used the random-effects model of DerSimonian and Laird with heterogeneity and sensitivity analyses. The primary outcome was sustained viral response (SVR, as a measure of efficacy), and the secondary outcome was the drop-out rate due to side-effects (as a measure of tolerability). Results : We identified eleven clinical studies (n = 235 unique patients) ; the rate of baseline kidney involvement ranged between 11% and 74%. The summary estimate of frequency of sustained viral response was 0.15 with a 95% Confidence Interval (CI) of 0.08 ; 0.22 (random-effects model). Significant heterogeneity occurred (P = 0.001 ; Chi2 = 28.9%). Stratified analysis did not meaningfully change the results. The frequency of patients stopping antiviral agents was 3.4% ; most patients experienced minor side effects which did not require interruption of therapy. Baseline cirrhosis (P [Product Details...]

MicroRNA Expression Profiles of Circulating Microvesicles in Hepatocellular Carcinoma

Price: €10,00

Background : Microvesicles (MVs) packaged with microribonucleic acids (miRNAs) have been shown to be released mainly from tumor cells. However, little information is known for miRNAs from MVs in hepatocellular carcinoma (HCC). Hence, we explored the MVs’ miRNAs expression profiles in HCC. Methods : MVs were collected from peripheral blood of HCC, chronic hepatitis B (CHB) and normal controls. miRNA from MVs were labeled and analyzed by Agilent miRNA microarry. Bioinformatics tools were used to analyze function of the differentially expressed MVs’ miRNAs. Results : A total of 242 aberrantly expressed miRNAs were identified in HCC-MVs compared with CHB-MVs and the control. Among them, 115 miRNAs were over-expressed with up to 31 fold difference (miR-671-5p) and 127 were down-expressed with up to 0.041 fold difference (miR-432) in HCC. By software miRror2.0, nucleolar protein 3 (NOL3) was found to be the core player among 300 target genes of top ten up-regulated miRNAs and serine/ arginine repetitive matrix 1(SRRM1) was central among the 219 targets of the top ten down-regulated miRNAs. We also analyzed GO categories for these predicted genes : cellular component, biological processes, and molecular function. The deregulation of MVs’ miRNAs and their target genes were closely involved in the pathways of HCC. Conclusions : Our study firstly demonstrated that miRNAs were differentially expressed in HCC-MVs compared with CHB and normal controls. Aberrant HCC-MVs miRNAs may play important roles in the development of HCC. (Acta gastroenterol. belg., 2013, 76, 386-392). [Product Details...]

Prevalence of and risk factors for H. pylori infection in healthy children and young adults in Belgium anno 2010/2011

Price: €10,00

Objective : Estimation of prevalence and risk factors for Helicobacter pylori (H. pylori) infection in children and young adults in Belgium. Study design : Five hundred and sixteen schoolchildren between 12 and 25 years old were tested for H. pylori infection using 13CUBT in different regions in Belgium. A questionnaire was used to evaluate risk factors. Results : Fifty six (11%) tested positive. In children born in Belgium, with parents from Belgium, 13 (3,2%) tested positive. In children born in a foreign country, 20 (60%) tested positive ; if born in Belgium but 1 or 2 parents were from a foreign country, 15 (30%) tested positive. Differences were significant (p [Product Details...]
