 Objective: The objective of this study is to analyze caspase-3 mRNA gene expression in a Wistar rat model of Alzheimer’s disease (AD) treated with Musa paradisiaca L. (MPL) ethanol extract or banana extract (BE)Methods: MPL was evaluated for its effect on the caspase-3 mRNA gene expression of rat amyloid beta (Aβ) induced, an AD model. Each model included twenty Wistar rats were randomized into five groups: K0, without AD induction and no BE; K1, AD induction and no BE; K2, AD induction+BE 250 mg/kg body weight (BW); K3, AD induction+BE 500 mg/kg; and K4, AD induction+BE 1000 mg/kg. AD induction was performed by Aβ1-42 (0.2 ug) injection at the intracerebroventricular area. mRNA caspase-3 level measurements were performed by real time-polymerase chain reaction.Results: Paired t-test analysis showed no significant differences of caspase-3 mRNA level before Aβ induction among five groups (p>0.05). At 6 weeks post-Aβ induction, there was significantly increased caspase-3 mRNA in all groups except K0 (p<0.05). Notably, after 3 weeks of BE administration, caspase-3 mRNA expression was significantly decreased in all BE-treated groups; in the K1 placebo group, caspase-3 mRNA expression increased. The maximum decreased caspase-3 mRNA expression was in group K4 (-BE 1000 mg/kg BW), and the minimum was in group K2 (-BE 250 mg/kg BW).Conclusion: The results revealed that the ethanolic extract of MPL fruit could decrease caspase-3 mRNA gene expression in AD rat.

Flavan-3-ols are a class of flavonoids that are widely distributed in fruits and beverages including red wine and apples. Consumption of flavanoid-rich food has been shown to exhibit anti-microbial, anti-oxidative, anti-inflammatory, and immune-modulating effects. To test the nutritional effects of flavanols on mRNA gene-expression of inflammatory and apoptotic marker genes, piglets were given two flavanoids-rich feeding regimens: a low flavanoid standard diet (SD) was compared with diets enriched with 3·5% apple pomace (APD) or 3·5% red-wine pomace (RWPD). The influence on mRNA expression levels was investigated in different immunological active tissues and in the gastro-intestinal tract (GIT). The investigation took place from 1 week prior weaning to 19 days post weaning in 78 piglets. The expression of expressed marker genes was determinate by one-step quantitative real-time (qRT-PCR): TNFα, NFκB as pro-inflammatory; IL10, as anti-inflammatory; caspase 3 as apoptosis; cyclin D1 as cell cycle marker; and nucleosome component histon H3 as reference gene.The feeding regimens result in tissue individual regulation of mRNA gene expression in all investigated organs. It was discovered that there were significant differences between the applied diets and significant changes during feeding time curse. Both pomace treatments caused a significant up-regulation of all investigated genes in liver. The effect on mesenterial lymph nodes and spleen was not prominent. In the GIT, the treatment groups showed a inhibitory effects on gene expression mainly in stomach and jejunum (NFκB, cyclin D1 and caspase 3). In colon the trend of caspase 3 was positive with the greatest change in the RWPD group.In jejunum and stomach the cell cycle turn over was reduced, whereas in liver the cell turn over was highly accelerate. The influence on inflammatory marker gene expression is mainly relevant in stomach. It is presume that both flavanoid rich feeding regimens have the potential to modulate the mRNA expressions of inflammatory, proliferation and apoptotic marker genes in the GIT and piglet organs.

The study was conducted to elucidate the effects of orally administered lactulose in combination with <i>Enterococcus faecium</i> on immune response of the intestinal tract in pre-ruminant calves. The mRNA expression of pro- and anti-inflammatory cytokines and proliferation and apoptosis markers were investigated in jejunum, ileum, colon and caecum. Simmental calves were fed diets containing 1% (L1) or 3% (L3) lactulose and the probiotic strain of the genus <i>E. faecium</i>, and compared with a non treated control group. Primarily the high dose feeding with lactulose showed an effect on several mRNA gene expression parameters. In the jejunum a down-regulation of the anti-apoptotic marker Bcl-xl was determined and IL-10 mRNA gene expression was 2.6-fold up-regulated (<i>P</i> < 0.05). In the colon a 1.9-fold (<i>P</i> < 0.05) up-regulation of IL-10 and only in caecum an about 2-fold increase of TGF-β1 (<i>P</i> < 0.05) was found for both lactulose feedings. Caspase 3 was up-regulated in caecum only in the 3% lactulose treated group (<i>P</i> < 0.05). The enhanced apoptotic rate of caspase 3 seems to be associated with a decrease in crypth depth due to lactulose supplementation. The results indicated that mainly the high 3% lactulose dose in probiotic-fed calves has an affect on the intestinal immune function and on diverse apoptotic markers.

The proteolytic processing of the amyloid-beta protein precursor plays a key role in the development of Alzheimer's disease. Cleavage of the amyloid-beta protein precursor may occur via two pathways, both of which involve the action of proteases called secretases. One pathway, involving beta- and gamma-secretase, liberates amyloid-beta protein, a protein associated with the neurodegeneration seen in Alzheimer's disease. The alternative pathway, involving alpha-secretase, precludes amyloid-beta protein formation. In this review, we describe the progress that has been made in identifying the secretases and their potential as therapeutic targets in the treatment or prevention of Alzheimer's disease.
