Abstract Aluminosilicate is the major component of clay minerals such as zeolite, bentonite and clinoptilolite. The minerals possess a number of beneficial activities, especially in regulating the immune system. The aims of the present study were to evaluate immune enhancing effects of dietary aluminosilicate supplement (DAS) in mice, and to demonstrate clearance effects of DAS against porcine circovirus type 2 (PCV2) in experimentally infected pigs as an initial step towards the development of an antibiotic substitute for use in pigs. Relative messenger RNA expression levels of interferon-gamma, interleukin-4 and tumor necrosis factor-alpha, phagocytic activities of polymorphonuclear leucocytes, serum antibody production level and spleen B cell ratio were significantly increased in the DAS groups of mice compared with the control group (each feeding group had three replications with 5 mice each). The results indicated that general immune activity including cellular and humoral immunity could be enhanced by DAS in mice. In experimentally PCV2-infected pigs, the load of viral genome in nasal swab, serum and lung of the DAS group of pigs was significantly decreased compared with the control group at 28 days post-infection (each group three pigs). Corresponding histopathological analyses demonstrated that pigs in the DAS group displayed mild and less severe abnormal changes compared with the control group, indicating that DAS reinforces clearance of PCV2 in experimentally infected pigs. This may relate to general immune enhancing effects of DAS in mice. Therefore DAS will help the health of animal, especially in swine. (c) 2009 Elsevier B.V. All rights reserved.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
