This study was carried out to identify the HSPA1A, TNF, IL1B and IL6 mRNA gene expression levels of Holstein dairy cattle sheltered in different floor types. Nineteen Holstein cows were used in this study. The cattle taken into research were divided into two groups as concrete (CON; n= 10) or rubber mat (RUB; n=9). HSPA1A, TNF, IL1B and IL6 mRNA genes are isolated from milk somatic cells and the gene expression is identified by Real-Time PCR. Between the groups, the HSPA1A (P less than 0.01) and IL1B (P less thann 0.05) gene expression levels were found to be statistically significant, while IL6 and TNF gene expressions were not significant. While the IL6 and TNF gene expression differences are insignificant between the groups, numerically higher level of gene expression was observed in the CON group. Overall results of the study suggested that the rubber mat floor type has a positive impact on both the animal welfare and the udder health.

Objective: We recently reported that post-resuscitation normoxic therapy attenuates oxidative stress in multiple organs and improves post-cardiac arrest (CA) organ injury, oxygen metabolism, and survival. Yet, detailed mechanisms of gene expression patterns and signaling pathways mitigated by normoxic therapy have not been elucidated. Therefore, we assessed post-resuscitation normoxic therapy-modified gene expression of oxidative stress-related signaling molecules. Methods: Rats were resuscitated from 10 minutes of asphyxial CA and divided into 2 groups: those that inhaled 100% supplemental O 2 (CA-FIO2 1.0) and those that inhaled 30% supplemental O 2 (CA-FIO2 0.3). Control groups were also prepared for comparison (control-FIO2 1.0, control-FIO2 0.3). At 2 hours after resuscitation, brain and heart tissues were collected, and mRNA purifications followed by real-time PCR measurements were performed to compare gene expression of hyperoxia-induced inflammatory and apoptosis-related signaling pathways amongst these groups. Results: In the brain, relative IL-1 beta mRNA gene expression levels, which represent inflammatory signaling pathways, increased post-CA (8.1±2.3 in CA-FIO2 1.0 and 1.0±0.4 in control-FIO2 0.3, p<0.05), but were significantly attenuated by normoxic therapy (2.3±0.2 in CA-FIO2 0.3, p<0.05). Likewise, normoxic therapy significantly reduced oxidative stress-induced inflammatory (NFKB1, TGFB1, MAPK14, TRAF6) and apoptosis-related (BAX, EGF) mRNA gene expression levels in the brain, whereas no statistical differences were detected in the heart. Conclusions: Post-CA normoxic therapy significantly attenuated the gene expression of oxidative stress-induced inflammation and apoptosis in the brain, while there were no remarkable changes in the heart. Therefore, it is inferred that the heart is more tolerant to hyperoxic injury compared to the brain.

Recently, it has been demonstrated that aggressive B-cell non-Hodgkin lymphomas (B-NHL) split up into distinct subgroups such as molecular Burkitt (mBL) and molecular non-Burkitt lymphomas (non-mBL). The non-mBL group can further be devided in activated B-cell (ABC) and germinal center B-cell (GCB) like lymphomas. In the present investigation we aimed at unravelling correlations of single or multiple chromosomal imbalances, their respective regional mRNA gene expression levels and the above mentioned molecular subgroups. Aggressive B-NHL samples (n=255) were investigated within the German network project Molecular Mechanisms in Malignant Lymphomas (MMML). Data from genomic arrayCGH analysis were evaluable for 213 lymphoma cases. Consensus review diagnoses according to WHO criteria were: DLBCL (n=154), atypical BL (n=20), typical BL (n=15) and other aggressive B-NHL (n=24). For all cases gene expression analysis was done using the Affymetrix U133A GeneChip. FISH data were available for translocations involving the MYC locus and for t(14;18). Using arrayCGH, chromosomal gains in more than 10% of all cases have been identified on 18q(24.4%), 3q(19.8%), 1q(19.1%), 12q(16.7%) 2p(16.3 %), 7p and 7q(16.3%), 6p(13.2%) and 11q(12.5%). Deletions occurred most frequently on chromosome arm 6q(20.3%), 17p(15.4%), 9p(14.8%) and 8p(10%). Molecular BLs had significantly less chromosomal aberrations than non-mBLs but frequently show gains of chromosome arm 1q. Non-mBLs show higher genomic complexity and strikingly differing aberration patterns for GCB (more than 20% gains on 1q, 2p, 7q, 11q, 12q) and ABC (more than 20% gains on 3q, 9p, 18q, loss on 6q) type lymphomas. These findings were also supported by results of genomic clustering algorithms such as non negative matrix factorization. For a large number of recurrent chromosomal aberrations we were able to delineate minimal aberrant chromosomal regions and to correlate respective regional mRNA gene expression levels. Strong proportional correlations were found for gains of 18q21.1-q21.33 and losses of 6q21-q24.3. In conclusion, genomic aberration patterns closely correlate with distinct molecular subtypes of aggressive B-NHL. These aberration patterns might serve as surrogate markers providing diagnostic and prognostic information as well as a basis for targeted gene investigations and risk adapted therapy studies.

BACKGROUND: Some of colorectal cancers (CRCs) are familial, however, heterozygote relatives have approximately 80% lifetime risk of cancer. Risk assessment of CRC’s family could be calculated by direct measurement of mRNA gene expression and Bayesian theorem which is modifying initial background of pedigree risk with additional conditional information. This application has not been reported.METHODS: The cross-sectional translational sequential studies were performed: (1) adenomatous polyposis coli (APC) and MutS homolog (MSH)2 mRNA quantitative RT PCR gene expressions in tissue and whole blood CRC patients; (2) gene expression was determined in matched controls; and (3) pedigree and Bayesian analysis was calculated in the patient’s family of Proband.RESULTS: Fourty CRC and 31 control subjects were enrolled. The mean blood APC level control’s group was 13,261±670 fold-change (fc) and blood MSH2 level was 12,219±756 fc. The cut-off points for hereditary APC was 12,195 fc and MSH2 was 11,059 fc. The mean APC blood level in CRC subject was 11,578±2,638 fc and MSH2 blood level was 11,411±2,912 fc. There were significant differences APC and MSH level between tissue and blood level in CRC. Eight of 40 CRC subjects had a history of familial CRC. Four patients and 10 Probands were available for recurrence risk evaluation of pedigree analysis, RNA PCR quantitative and Bayesian calculation.CONCLUSION: There was determined a cut-off point of hereditary mRNA quantitative expression. The APC and MSH2 levels in CRC subjects were significantly lower than controls. Bayesian analysis allowed for the calculation of relative risk in CRC family members and considered in clinical practice.KEYWORDS: hereditary CRC, APC gene, MSH gene, Bayesian analysis

Abstract Although expression of the genes ERG (ETS-related gene) and BAALC (brain and acute leukemia, cytoplasmic) predicts outcome in acute leukemia, there is little information about their utility as markers of minimal residual disease (MRD). A real-time quantitative reverse transcriptase-polymerase chain reaction (RQ-PCR) was used to examine relative levels of ERG and BAALC gene expression in 11 patients with acute leukemia. Pretreatment and post-chemotherapy bone marrow (BM) samples were analyzed to quantify these transcripts. Peripheral blood (PB) samples were also obtained to evaluate the correlation of ERG and BAALC expression levels in BM and PB samples. Significant levels of ERG gene were expressed in all patients. In contrast with ERG, the levels of BAALC gene expression were significantly lower in some patients. Continuous monitoring of the ERG mRNA was performed and assessed a correlation between MRD levels and subsequent clinical courses. In patients with relative high expression of BAALC transcripts (>7x10exp-3/GAPDH), high levels of ERG gene expressions were consistently observed whether they were in remission status or not. In 2 patients with acute promyelocytic leukemia (APL), MRD was simultaneously monitored by RQ-PCR using primers for PML/RAR alpha. Changes in expression levels of PML/RAR alpha and ERG presented poor correlation. While, in other patients with relative low expression of BAALC transcripts (<7x10exp-3/GAPDH), ERG gene expression levels gradually decreased after the induction therapy and following consolidation treatments. In patients unable to attain remission, ERG expression levels remained high. Thus, the quantitation of the ERG gene expression made it possible to assess MRD in patients with acute leukemia (except for APL) carrying low BAALC expression. To our knowledge, this is the first report concerning the use of ERG mRNA expression for MRD monitoring.

Sampling for DUS test of flower colors should be fixed at the stages and sites that petals are fully colored, and besides, flower colorations are uniform among individuals and stable for a period of time to allow testers to get consistent results. It remains a problem since spatial and temporal flower colorations are reported a lot but their change traits are little discussed. In this study, expression state, uniformity and stability of color phenotypes, anthocyanin contents, and gene expression levels were taken into account based on measurements at 12 development stages and three layers (inner, middle, and outer petals) of two varieties of Ranunculus asiaticus L. to get their best sampling. Our results showed that, outer petals of L9–L10 (stage 9–stage 10 of variety ‘Jiaoyan zhuanhong’) and C5–C6 (stage 5–stage 6 of variety ‘Jiaoyan yanghong’) were the best sampling, respectively. For DUS test, it is suggested to track flower colorations continuously to get the best sampling as well as representative colors since different cultivars had different change traits, and moreover, full expression of color phenotypes came later and lasted for a shorter duration than those of anthocyanin contents and gene expressions. Our innovation exists in following two points. Firstly, a model of change dynamic was introduced to illustrate the change traits of flower colorations, anthocyanin contents, and gene expressions. Secondly, genes used for expression analysis were screened on account of tentative anthocyanins, which were identified based on comparison between liquid chromatography–mass spectrometry (LC–MS) results and molecular mass and mass fragment pattern (M2) of each putative anthocyanin and their fragments deduced in our previous study. Gene screening in this regard may also be interest for other non-model plant genera with little molecular background.

Abstract: Infection with Escherichia coli (E. coli) is a common disease in poultry industry. The use of antibiotics to treat diseases is facing serious criticism and concerns. The medicinal plants may be effective alternatives because of their multiplex activities. The aim of this study was to investigate the effects of cinnamon extract on the levels of liver enzymes, tumor necrosis factor-alpha (TNF-α) and nuclear factor-kappa B (NF-κB) gene expressions in liver of broiler chickens infected with E. coli. Ninety Ross-308 broilers were divided into healthy or E. coli-infected groups, receiving normal or cinnamon extract (in concentrations of 100 or 200mg/kg of food) supplemented diets. E. coli suspension (108cfu) was injected subcutaneously after 12 days cinnamon administration. Seventy-two hours after E. coli injection, the blood samples were taken for biochemical analysis of liver enzymes in serum (spectrophotometrically), and liver tissue samples were obtained for detection of gene expression of inflammatory markers TNF-α and NF-κB, using real-time PCR. Infection with E. coli significantly increased the levels of TNF-α and NF-κB gene expressions as well as some liver enzymes including creatine-kinase (CK), lactate-dehydrogenase (LDH), alanine-transferase (ALT) and aspartate-transferase (AST) as compared with control group (P<0.05). Pre-administration of cinnamon extract in broilers diet (in both concentrations) significantly reduced the tissue levels of TNF-α and NF-κB gene expressions and enzymes CK and ALT in serum of broiler chickens inoculated with E. coli in comparison with E. coli group (P<0.05 and P<0.01). The levels of LDH and AST were significantly decreased only by 200mg/kg cinnamon extract in infected broilers. The level of alkaline-phosphatase (ALP) was not affected in any groups. Pre-administration of cinnamon extract in diets of broiler chickens inoculated with E. coli could significantly reduce the gene expression levels of pro-inflammatory mediators and liver enzymes activities, thereby protecting the liver against this pathologic condition.

4647 Background: Lapatinib (GW572016) is a dual tyrosine kinase inhibitor of EGFR and HER2. In SWOG0413 trial, advanced or metastatic gastric cancer patients were treated with lapatinib. In this study, we investigated whether gene expressions and polymorphisms of EGF and angiogenesis pathway genes were associated with clinical outcome in the patients enrolled in SWOG0413 trial. Methods: A total of 46 patients were enrolled in SWOG0413 trial and treated with lapatinib. Blood and tissue samples were available from 42 and 37 patients, respectively. RT-PCR was performed for intratumoral gene expression levels of EGFR, HER2, VEGF, IL-8, COX2 and cyclin D1 genes. We also analyzed 8 polymorphisms in the EGF, EGFR, HER2, VEGF, IL-8, COX2 and cyclin D1 genes by PCR-RFLP. Results: Patients who have lower IL-8 [median overall survival (OS), 6 vs 3 months, p=0.03] and higher HER2 (6 vs 3 months, p=0.005) gene expression levels showed better OS. According to gene polymorphisms, patients who have A allele of IL-8 T251A polymorphism showed improved OS (A/A, 10 months vs T/A, 5 months vs T/T 3 months, p=0.04). And patients with A allele of IL-8 T251A and T allele of VEGF C936T polymorphisms showed better response rates (p<0.01, p<0.01, respectively). All other polymorphisms and gene expressions did not show significant association with clinical outcome. Conclusions: Our results suggest that intratumoral gene expression levels of HER2 and IL-8 and polymorphism in IL-8 are potential molecular predictors for survival in patients with advanced or metastatic gastric cancer treated with lapatinib. And polymorphisms in IL-8 and VEGF genes may be potential markers in predicting response in this population. A larger prospective study is needed to validate and confirm these preliminary findings.

Objective: This study was conducted to explore the expression levels of HTR1A gene in a sample of Egyptian autistic children. Methods: Thirty autistic patients (18 boys, 12 girls) and 20 controls were enrolled in the study. From each child, we isolated RNA samples from whole blood. Quantitative Real-Time PCR (qRT-PCR) was used to measure the gene expressions of HTR1A and normalized to the house keeping gene, beta-actin. Results: The HTR1A gene expression of healthy controls and ASD subjects were varied significantly (p =0.0062). As compared to control healthy subjects, the HTR1A expressions were greatly reduced in samples of ASD. Conclusion: HTR1A gene expression level is a candidate gene for further studies to explore its potential roles in ASD related pathways.

Stochastic dependence between gene expression levels in microarray data is of critical importance for the methods of statistical inference that resort to pooling test statistics across genes. The empirical Bayes methodology in the nonparametric and parametric formulations, as well as closely related methods employing a two-component mixture model, represent typical examples. It is frequently assumed that dependence between gene expressions (or associated test statistics) is sufficiently weak to justify the application of such methods for selecting differentially expressed genes. By applying resampling techniques to simulated and real biological data sets, we have studied a potential impact of the correlation between gene expression levels on the statistical inference based on the empirical Bayes methodology. We report evidence from these analyses that this impact may be quite strong, leading to a high variance of the number of differentially expressed genes. This study also pinpoints specific components of the empirical Bayes method where the reported effect manifests itself.
