One
ACE single nucleotide polymorphism (SNP) (rs4291) and two AGT SNPs (rs 699 and rs 4762) were genotyped from genomic DNA with direct sequencing. Results: PTDM developed in 49 (16.2%) of 302 subjects. Subjects in the PTDM were older than those in the non-PTDM. There was a significant difference between the two groups in tacrolimus use (p=0.03). Of the three SNPs, the rs4762 of the AGT gene was significantly associated with Torin 1 chemical structure the development of PTDM in the dominant models (p = 0.03) after adjusting for age and tacrolimus usage. Conclusions: AGT gene rs4762 polymorphisms may serve as genetic markers for the development of PTDM. The exact molecular mechanisms still need to be clarified. Copyright (C) 2013 S. Karger AG, Basel”
“Adjuvant cancer chemotherapy can cause long-lasting, cognitive deficits. It is postulated that these impairments are due to these drugs targeting
neural precursors within the adult hippocampus, the loss of which has been associated with memory impairment.
The present study investigates the effects of the chemotherapy, methotrexate (MTX) on spatial working memory and the proliferation and survival of the neural precursors involved in hippocampal neurogenesis, and the possible neuroprotective properties of the antidepressant fluoxetine.
Male Lister hooded rats were administered MTX (75 mg/kg, two i.v. doses a week apart) followed by leucovorin rescue (i.p. 18 h after MTX at 6 mg/kg and at 26, 42 and 50 h at 3 mg/kg) and/or fluoxetine (10 mg/kg/day in drinking water for 40 days). Memory was tested using the novel location recognition Tozasertib solubility dmso (NLR) test. Using markers, cell proliferation (Ki67) and survival (bromodeoxyuridine/BrdU),
in the dentate gyrus were quantified.
MTX-treated rats showed a cognitive deficit in the NLR task compared with the vehicle and fluoxetine-treated groups. Cognitive ability was restored in the group receiving both MTX and fluoxetine. MTX reduced both the number of proliferating cells in the SGZ and their survival. This was prevented by the co-administration of fluoxetine, which alone increased cell numbers.
These results demonstrate that MTX induces an impairment in spatial working memory and has a negative long-term effect STK38 on hippocampal neurogenesis, which is counteracted by the co-administration of fluoxetine. If translatable to patients, this finding has the potential to prevent the chemotherapy-induced cognitive deficits experienced by many cancer survivors.”
“Background/Aims: To determine the effect of arterial blood pressure (BP) reduction on endocan and soluble cell adhesion molecules’ (sCAM) plasma concentration and expression of their ligands on circulatory leukocyte subpopulations. Methods: 24 hypertensive subjects of both sexes (age: 53 +/- 8 yrs) were treated with Ca-channel blocker, amlodipin (5-10 mg/day for 8 weeks; to reach BP <= 139/89mmHg). The serum sCAMs and endocan concentrations were determined by ELISA kits.
