Significance of CASP8AP2 and H2AFZ expression in survival and risk of relapse in children with acute lymphoblastic leukemia.
Leuk. Lymphoma
PUBLISHED: 02-24-2014
Show Abstract
Hide Abstract
Novel biomarkers for risk refinement and stratification in childhood acute lymphoblastic leukemia (ALL) are needed to optimize treatment results. We studied the expression of CASP8AP2 and H2AFZ associated with relapse and survival in bone marrow samples from newly diagnosed children with ALL. We found: (a) an increased risk for early relapse in those patients with low expression of CASP8AP2 (odds ratio [OR] 3.93, 95% confidence interval [CI] 1.40-11.02, p < 0.05) confirming its usefulness as a predictive risk marker, although H2AFZ did not present the same effect; (b) patients with low expressions of CASP8AP2 and H2AFZ had inferior survival rates (p < 0.001); (c) the predictive values regarding low expressions of H2AFZ and CASP8AP2 and high white blood cell count suggest that these features could help to identify more accurately patients at greater risk of relapse.

The consumption of n-3 polyunsaturated fatty acids differentially modulates gene expression of peroxisome proliferator-activated receptor alpha and gamma and hypoxia-inducible factor 1 alpha in subcutaneous adipose tissue of obese adolescents.

Hide Abstract
The aim of this study was to evaluate the effect of long-chain omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation on metabolic state and gene expression in subcutaneous adipose tissues of obese adolescents. Obese adolescents (n = 26, 10 girls and 16 boys) aged 12.4 ± 2.1 years were assigned to a 12-week regimen of n-3 PUFA intake. Five times per day, subjects received a food supplement consisting of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (3 g per day, 944 mg EPA, and 2,088 mg DHA). Blood parameters were measured, and subcutaneous adipose tissue biopsies were analyzed to determine gene expression at baseline and after 12 weeks. Students t test and the Wilcoxon signed-rank test were used to estimate differences in arithmetic means of pre- and post-dietary supplementation for various anthropometric, biochemical, clinical, and gene expression parameters. After 12 weeks, n-3 PUFA consumption was associated with decreased body mass index (29.7 ± 4.6 vs. 27.8 ± 4.4 kg/m(2); P < 0.001), waist circumference (93.2 ± 9.9 vs. 90.5 ± 10.0 cm; P < 0.003), hip circumference (102.9 ± 10.9 vs. 101.1 ± 10.9 cm; P < 0.014), and blood triglyceride levels (220.8 ± 27.4 vs. 99.7 ± 32.7 mg/dL; P < 0.001). Fatty acid supplementation/n3 PUFA supplementation was associated with a downregulated expression of the genes encoding PPAR? and PGC-1? (P < 0.001), and an upregulated expression of the genes encoding PPAR? (P < 0.007) and SREBP1 (P < 0.021). The expressions of SOD2 (P < 0.04), CAT (P < 0.001), GPX3 (P < 0.032) and HIF-1? protein also decreased. Our study demonstrated that n-3 PUFA consumption and dietary restriction improved the anthropometric parameters and decreased the triglycerides levels of the adolescents, suggesting a reduction in hypoxia in subcutaneous adipose tissue.

Association of the I148M/PNPLA3 variant with elevated alanine transaminase levels in normal-weight and overweight/obese Mexican children.
Gene
PUBLISHED: 01-29-2013
Show Abstract
Hide Abstract
Non-alcoholic fatty liver disease (NAFLD) and elevated alanine transaminase (ALT) levels are common in obese Hispanic adults and children. Recently, a PNPLA3 gene variant (I148M) was strongly associated with NAFLD and higher ALT levels in obese adults, including Hispanics. The aims of this study were to estimate the frequency of elevated ALT levels, and to address the influence of obesity and PNPLA3/I148M on ALT levels in a general population sample of Mexican school-aged children.

Transcript levels of Toll-Like Receptors 5, 8 and 9 correlate with inflammatory activity in Ulcerative Colitis.
BMC Gastroenterol
PUBLISHED: 12-20-2011
Show Abstract
Hide Abstract
Dysregulation of innate immune response by Toll-Like Receptors (TLRs) is a key feature in Ulcerative Colitis (UC). Most studies have focused on TLR2, TLR3, and TLR4 participation in UC. However, few studies have explored other TLRs. Therefore, the aim of this study was to evaluate the mRNA profiles of TLR1 to 9 in colonic mucosa of UC patients, according to disease activity.

We undertook this study to determine the baseline gene expression of IFI27, IFIT1, IFI6, ISG15, IRF-1, IRF-3, OAS-2 and CXCL10 and its usefulness as molecular markers of response to antiviral treatment with peg-IFN? 2b/RBV in patients with hepatitis C virus genotype 1 (HCV-1).

Hide Abstract
Influenza viruses pose a threat to human health because of their potential to cause global disease. Between mid March and mid April a pandemic influenza A virus emerged in Mexico. This report details 202 cases of infection of humans with the 2009 influenza A virus (H1N1)v which occurred in Mexico City as well as the spread of the virus throughout the entire country.

Hide Abstract
In March 2009, public health surveillance detected increased numbers of influenza-like illness presenting to hospitals in Mexico City. The aetiological agent was subsequently determined to be a novel influenza A (H1N1) triple reassortant, which has spread worldwide. As a consequence the World Health Organisation has declared the first Influenza pandemic of the 21st century.

Changes in peripheral blood mononuclear cells glutamine synthetase mRNA after exercise in healthy volunteers: exploring an alternative proposal for non hepatic ammonia metabolism.
Rev. Invest. Clin.
Show Abstract
Hide Abstract
Glutamine synthetase (GS) plays a central role in the inter-organ metabolism of ammonia and hepatic encephalopathy. The main objective of the present work was to disclose the possible effect of exercise on GS mRNA expression in peripheral blood mononuclear cells (PBMC) within a group of healthy volunteers.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
