Inhibitory effect of the peptide epitalon on the development of spontaneous mammary tumors in HER-2/neu transgenic mice.
    International journal of cancer, 2002, Sep-01, Volume: 101, Issue:1

    Female FVB/N HER-2/neu transgenic mice from the age of 2 months were subcutaneously injected with saline, the peptide Epitalon(R) (Ala-Glu-Asp-Gly) or with the peptide Vilon(R) (Lys-Glu) in a single dose of 1 microg/mouse for 5 consecutive days every month. Epitalon treatment reduced the cumulative number and the maximum size of tumors (p < 0.05). Furthermore, the number of mice bearing 1 mammary tumor was increased, whereas the number of mice bearing 2 or more mammary tumors was reduced in Epitalon-treated in comparison to saline-treated animals (p < 0.05). The size but not the number of lung metastases was reduced in Epitalon-treated compared to saline-treated mice (p < 0.05). The treatment with Vilon produced significant negative effects when compared to the control group, with an increased incidence of mammary cancer development (p < 0.05), a shorter mean latent period of tumors (p < 0.05) and an increased cumulative number of tumors (p < 0.05). A 3.7-fold reduction in the expression of HER-2/neu mRNA was found in mammary tumors from HER-2/neu transgenic mice treated with Epitalon compared to control animals. The expression of mRNA for HER-2/neu was also partially reduced in Vilon-treated mice, but it remained significantly higher in Vilon- than in Epitalon-treated animals (1.9-fold increase). The data demonstrate the inhibitory effect of Epitalon in the development of spontaneous mammary tumors in HER-2/neu mice, suggesting that a downregulation of HER-2/neu gene expression in mammary adenocarcinoma may be responsible, at least in part, for the antitumor effect of the peptide.

Effect of Vilon and Epithalon on glucose and glycine absorption in various regions of small intestine in aged rats.
    Bulletin of experimental biology and medicine, 2002, Volume: 133, Issue:5

    Vilon (Lys-Glu) and Epithalon (Ala-Glu-Asp-Gly) administered orally for 1 month improved transport characteristics of the small intestine in aged rats. Vilon enhanced passive glucose accumulation in the serous fluid in inverted sac made from the distal region of the small intestine, while Epithalon enhanced this process in the medial region. Vilon stimulated active glucose accumulation in the serous sac of the medial small intestine, Epithalon - in the proximal and distal small intestinal segments. Glycine absorption increased only in the proximal intestinal segment under the effect of Epithalon.
