Background. The suppression of Helicobacter pylori (H. pylori) decreases H. pylori-related diseases. The probiotics have an inhibitory effect on H. pylori. Aim. We investigated the effects of long-term use of yogurt on H. pylori based on Mongolian gerbils' model. Materials and Methods. Yogurt (containing a supplement of Lactobacillus acidophilus, Bifidobacterium lactis, etc.) was used. Forty-si...
Equivalence class formation by college students was influenced through the prior acquisition of conditional discriminative functions by one of the abstract stimuli (C) in the to-be-formed classes. Participants in the GR-0, GR-1, and GR-5 groups attempted to form classes under the simultaneous protocol, after mastering 0, 1, or 5 conditional relations between C and other abstract stimuli (V, W, ...
RU40555 is a recently available glucocorticoid receptor (GR) antagonist that differs from RU486 by a methyl radical. We have used the mouse fibroblast cell line L929 to study the in vitro effects of RU40555 on GR translocation and function and on the membrane steroid hormones transporter. The results showed that: 1) RU40555 competed for the binding of labelled dexamethasone (Dex) with a K(i) of...
FKBP52 is a tetratricopeptide repeat (TPR) protein with peptidyl-prolyl isomerase activity and is found in steroid receptor complexes, including glucocorticoid receptor (GR). It is generally accepted that FKBP52 has a stimulatory effect on GR transcriptional activity. However, the mechanism by which FKBP52 controls GR is not yet clear, with reports showing effects on GR hormone-binding affinity...
The structure of purified preparations of activated (DNA-binding) glucocorticoid receptor (GR) was analyzed in the presence or absence of DNA. A 35-base pair DNA fragment harboring a strong GR-binding site from the mouse mammary tumor virus promoter (-189/-166) was used for stoichiometric analysis of the GR . DNA complex. Glycerol gradient centrifugation was utilized in order to separate the 6 ...
Abnormal glucocorticoid and neurotrophin signaling has been implicated in numerous psychiatric disorders. However, the impact of neurotrophic signaling on glucocorticoid receptor (GR)-dependent gene expression is not understood. We therefore examined the impact of brain-derived neurotrophic factor (BDNF) signaling on GR transcriptional regulatory function by gene expression profiling in primary...
Respiratory syncytial virus (RSV)-induced bronchiolitis in infants, although inflammatory in nature, is not responsive to glucocorticoids. We have recently shown that RSV-infected lung epithelial cells have impaired glucocorticoid receptor (GR)-mediated transactivation. In this study, we show that the N-terminal region of GR is required for RSV repression of GR transactivation and that RSV infe...
