Abstract: We performed a functional genomic analysis to study the effect of epicatechin and polyphenolic cocoa extract in the human colon adenocarcinoma cell line Caco-2. The specific Human Hematology/Immunology cDNA arrays by Clontech, containing 406 genes in duplicate, were used. The differentially expressed genes were classified according to their level of expression, calculated as the ratio of the value obtained after each treatment relative to control cells, with a statistical significance of P < 0.05 (upregulated: ratio > 1.5; downregulated: ratio < 0.6). Treatment with epicatechin decreased the expression of 21 genes and upregulated 24 genes. Upon incubation with the cocoa polyphenolic extract, 24 genes were underexpressed and 28 were overexpressed. The changes in expression for ferritin heavy polypeptide 1 (FTH1), mitogen-activated protein kinase kinase 1 (MAPKK1), signal transducer and activator of transcription 1 (STAT1), and topoisomerase 1 upon incubation with epicatechin, and for myeloid leukemia factor 2 (MLF2), CCAAT/enhancer binding protein gamma (C/EBPG), MAPKK1, ATP-binding cassette, subfamily c member 1 (MRP1), STAT1, topoisomerase 1, and x-ray repair complementing defective repair 1 (XRCC1) upon incubation with the cocoa polyphenolic extract were validated by RT-PCR. Changes in the messenger RNA levels for MAPKK1, STAT1, MRP1, and topoisomerase 1 upon incubation with either epicatechin or cocoa extract were further confirmed at the protein level by Western blotting. The changes in the expression of STAT1, MAPKK1, MRP1, and FTH1 genes, which are involved in the cellular response to oxidative stress, are in agreement with the antioxidant properties of cocoa flavonoids. In addition, the changes in the expression of C/EBPG, topoisomerase 1, MLF2, and XRCC1 suggest novel mechanisms of action of flavonoids at the molecular level..

Abstract: Ractopamine hydrochloride (RAC) has consistently led to an advantage in carcass cutting yields of finishing pigs and remains a common feed additive in US finishing pig diets. Less is known about the effect of RAC on further processing characteristics. Some researchers have reported advantages in ultimate pH of the LM in pigs fed RAC. If a greater ultimate pH was also observed in hams, the increased pH could affect further processing characteristics and lead to better protein interaction and improved textural properties. The objective of this experiment was to determine if RAC-fed pigs yielded hams with a greater ultimate pH, and if so, whether or not that advantage improves textural properties and water retention of further processed hams. Two hundred hams from barrows and gilts fed RAC or control diets were selected based on HCW. Hams were fabricated into 5 separate pieces to determine cutting yields, and 6 muscles were evaluated for ultimate pH. Hams were processed to make cured and smoked hams. Ractopamine increased cutting yields of the whole ham (P < 0.0001), inside (P < 0.01), outside (P < 0.01), and knuckle (P < 0.01) when expressed as a percentage of chilled side weight. Ultimate pH of the rectus femoris, vastus lateralis, and semitendinosus were all 0.06 pH units greater (P < 0.05), the biceps femoris was 0.04 pH units greater (P = 0.02), and the semimembranosus and adductor muscles were 0.03 pH units greater in pigs fed 7.4 mg/kg of RAC when compared with control pigs. Cured hams from RAC-fed pigs were heavier at all stages of production. No differences were detected in binding strengths (P = 0.88) or protein fat-free values (P = 0.13) between RAC (9.06 kg and 20.37) and control hams (9.01 kg and 20.13). Ractopamine increased cutting yields, total weight of cured hams, and ultimate muscle pH. Ractopamine can be fed to pigs to achieve the desired growth characteristic advantages and cutting yields without affecting further processed ham characteristics..

Abstract: Significant endeavor has been applied to identify functional therapeutic targets in glioblastoma (GBM) to halt the growth of this aggressive cancer. We show that the receptor tyrosine kinase EphA3 is frequently overexpressed in GBM and, in particular, in the most aggressive mesenchymal subtype. Importantly, EphA3 is highly expressed on the tumor-initiating cell population in glioma and appears critically involved in maintaining tumor cells in a less differentiated state by modulating mitogen-activated protein kinase signaling. EphA3 knockdown or depletion of EphA3-positive tumor cells reduced tumorigenic potential to a degree comparable to treatment with a therapeutic radiolabelled EphA3-specific monoclonal antibody. These results identify EphA3 as a functional, targetable receptor in GBM..
