Hydration and nutritional status in patients on home-dialysis-A single centre study.

Background: Over-hydration (OH) and malnutrition are prevalent among patients on dialysis therapy. The prevalence of OH and malnutrition as well as the risk factors associated with OH and malnutrition in our patients on home peritoneal dialysis (PD) and home haemodialysis (HD) are examined.

Design And Methods: This was a cross-sectional study.

Promyelocytic leukemia (PML) protein plays important roles in regulating cell adhesion, morphology, proliferation and migration.

PML protein plays important roles in regulating cellular homeostasis. It forms PML nuclear bodies (PML-NBs) that act like nuclear relay stations and participate in many cellular functions. In this study, we have examined the proteome of mouse embryonic fibroblasts (MEFs) derived from normal (PML(+/+)) and PML knockout (PML(-/-)) mice.

Comparative proteomic analysis reveals a function of the novel death receptor-associated protein BRE in the regulation of prohibitin and p53 expression and proliferation.

The brain and reproductive organ expressed (BRE) gene encodes a highly conserved stress-modulating protein. To gain further insight into the function of this gene, we used comparative proteomics to investigate the protein profiles of C2C12 and D122 cells resulting from small interfering RNA (siRNA)-mediated silencing as well as overexpression of BRE. Silencing of BRE in C2C12 cells, using siRNA, resulted in up-regulated Akt-3 and carbonic anhydrase III expression, while the 26S proteasome regulatory subunit S14 and prohibitin were down-regulated.

Tissue specific expression and sequence analysis of a stress responsive gene Bre in adult golden hamster (Mesocricetus auratus).

Bre (brain and reproductive organ-expressed) is a new and putative stress-modulating gene of yet unknown function. BRE has previously been shown to interact with type 1 tumor necrosis factor receptor (TNFR1) and modulate the action of TNF. Apart from the brain and reproductive organs, Bre and BRE are highly expressed in steroid producing tissues such as the adrenal gland.

Nucleophosmin/B23 is a proliferate shuttle protein associated with nuclear matrix.

It has become obvious that a better understanding and potential elucidation of the nucleolar phosphoprotein B23 involving in functional interrelationship between nuclear organization and gene expression. In present study, protein B23 expression were investigated in the regenerative hepatocytes at different periods (at days 0, 1, 2, 3, 4, 7) during liver regeneration after partial hepatectomy on the rats with immunohistochemistry and Western blot analysis. Another experiment was done with immunolabeling methods and two-dimensional (2-D) gel electrophoresis for identification of B23 in the regenerating hepatocytes and HepG2 cells (hepatoblastoma cell line) after sequential extraction with detergents, nuclease, and salt.

Expression of a conserved mouse stress-modulating gene, Bre: comparison with the human ortholog.

Mouse Bre, an evolutionarily conserved stress-modulating gene, like its human counterpart, is expressed in multiple alternative transcripts. The main transcript, which is ubiquitously expressed, encodes a protein that binds tumor necrosis factor receptor 1 (TNF-R1) and downregulates TNF-induced activation of NF-kappaB. Alternative splicing of mouse Bre occurs only at the 5' region of the gene, generating either nonfunctional transcripts or transcripts that can encode putative protein isoforms differ at the N-terminal sequence.

[Expression and relocation of B23 in the process of rat liver cell hyperplasia and liver regeneration].

Objective: To study the B23 expression and relocation in the process of liver regeneration at different time periods after partial hepatectomy (PH) on healthy rats, and to study the feasibility of using B23 as a proliferation marker.

Methods: Eighteen rats underwent partial hepatectomy (PH). The regenerative liver tissues were obtained at day 1, 2, 3, 4,and 7 after PH.
