Abstract In a counter-balanced, cross-over study, we examined the contributions of serotonergic systems to the acquisition of social dominance in adult male vervet monkeys. Subjects were members of 12 social groups, each containing 3 adult males, at least 3 adult females, and their offspring. Animals were observed in 5 intervals including a first baseline, a first experimental, a second baseline, a second experimental, and a third baseline period. At the end of the first baseline period, the dominant male was removed from each group. In each group, one of the two remaining subordinate males was selected at random for treatment and during the first experimental period, 6 of the 12 treated males received drugs that enhanced serotonergic activity (3 were given tryptophan 40 mg/kg/day and 3 fluoxetine 2 mg/kg/day). The other 6 treated males received drugs that reduced serotonergic function (3 were given fenfluramine 2 mg/kg/day and 3 cyproheptadine 60 micrograms/kg/day). At the end of the first experimental period, the original dominant male was returned to his group and the second baseline period began. In all instances, the originally dominant male regained his dominant position. The second experimental period began with the dominant male again being removed and, the 12 treated males were given the treatment they had not received in the first experimental period. At the start of the third 12-week baseline period, the original dominant male was returned to his group and resumed his dominant status. When the 12 treated subjects received tryptophan or fluoxetine, they became dominant in all instances. When they received fenfluramine or cyproheptadine, their vehicle-treated cage mates became dominant. The sequence of the behavioral changes shown by the treated males as they acquired dominance status paralleled those seen in naturalistic conditions. These observations support the distinction between dominance and aggression and strongly suggest that when hierarchical relationships are uncertain, serotonergic mechanisms may mediate the behaviors which permit a male to attain high dominance status.

    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.
