The magnesium concentrations in plasma and cells could be affected by diet, disease and genetic factors. To characterise the genetic factors involved in the regulation of magnesium homeostasis, Low (MgL) and High (MgH) magnesium status mice were developed by bidirectional selective breeding. The effects of a low-magnesium diet on the magnesium status parameters were analysed in these mice. Usin...

The maintenance of proteome integrity is of primary importance in post-mitotic tissues such as muscle cells; thus, protein quality control mechanisms must be carefully regulated to ensure their optimal efficiency, a failure of these processes being associated with various muscular disorders. Duchenne muscular dystrophy (DMD) is one of the most common and severe forms of muscular dystrophies and...

Currently, with the increase of morbidity and mortality rate, gastric cancer (GC) is attracting increasing attention in China. Bcl‑2‑associated athanogene 4 (BAG4) has been identified as a tumor promoter in several tumors, but its role in GC remains unknown. The present study aimed to detect the expression of BAG4 and determine its function in the progression of GC. The results from reverse tra...

Bcl2-associated athanogene 3 (BAG3) has been reported to be involved in aggressive progression of many tumors. In the present study, we examined the expression of BAG3 in human cervical cancer (CC) tissues and investigated the role of BAG3 in SiHa and HeLa cell growth, migration, and invasion. Here, we found that most of CC tissues highly expressed the protein and mRNA of BAG3, while their expr...

A ubiquitously expressed nuclear receptor-associating protein of approximately 46 kDa (RAP46) was identified recently. Interaction experiments with in vitro-translated proteins and proteins contained in cell extracts revealed that a great variety of cellular regulators associate with RAP46. However, in direct interaction tests by the far-Western technique, only 70 kDa proteins showed up and wer...

Senescence is a prominent solid tumor response to therapy in which cells avoid apoptosis and instead enter into prolonged cell cycle arrest. We applied a quantitative proteomics screen to identify signals that lead to therapy-induced senescence and discovered that Bcl2-associated athanogene 3 (Bag3) is up-regulated after adriamycin treatment in MCF7 cells. Bag3 is a member of the BAG family of ...

Protein-protein interactions mediated through the C-terminal Bcl-2-associated athanogene (BAG) domain of BAG-1 are critical for cell survival and proliferation. Thioflavin S (NSC71948)-a mixture of compounds resulting from the methylation and sulfonation of primulin base-has been shown to dose-dependently inhibit the interaction between BAG-1 and Hsc70 in vitro. In human breast cancer cell line...

BCL2-associated athanogene cochaperone 6 (Bag6) plays a central role in cellular homeostasis in a diverse array of processes and is part of the heterotrimeric Bag6 complex, which also includes ubiquitin-like 4A (Ubl4A) and transmembrane domain recognition complex 35 (TRC35). This complex recently has been shown to be important in the TRC pathway, the mislocalized protein degradation pathway, an...

The Serum- and Glucocorticoid-induced Kinase 1, SGK1, exhibits a broad range of cellular functions that include regulation of the number of ion channels in plasma membrane and modulation of signaling pathways of cell survival. This diversity of functions is made possible by various regulatory processes acting upon the SGK1 gene, giving rise to various isoforms: SGK1_v1-5, each with distinct pro...
