Objective(s):In previous investigations, we have shown para-nonylphenol (p-NP) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (MSCs) in vitro. In this study, we first treat the rats with p-NP, then carried out the biochemical and morphological studies on MSCs. Materials and Methods: Proliferation property of cells was evaluated with t...
Although the nuclear envelope is known primarily for its role as a boundary between the nucleus and cytoplasm in eukaryotes, it plays a vital and dynamic role in many cellular processes. Studies of nuclear structure have revealed tissue-specific changes in nuclear envelope architecture, suggesting that its three-dimensional structure contributes to its functionality. Despite the importance of t...
Background: Endometrial remodeling occurs during each menstrual cycle in women. Reports have shown that, in a variety of cell types, processes such as proliferation, signaling complex formation and extra cellular matrix remodeling require a cytoplasmic tyrosine kinase, focal adhesion kinase (FAK). The present study has focused on the expression pattern of FAK in human endometrium during the men...
Alteration of the nuclear Ca2+ transient is an early event in cardiac remodeling. Regulation of the nuclear Ca2+ transient is partly independent of the cytosolic Ca2+ transient in cardiomyocytes. One nuclear membrane protein, emerin, is encoded by EMD, and an EMD mutation causes Emery-Dreifuss muscular dystrophy (EDMD). It remains unclear whether emerin is involved in nuclear Ca2+ homeostasis. ...
Background: During the later stages of spermatogenesis, spermatid nuclear remodeling and condensation are associated with histone modifications and the sequential displacement of histones by transition proteins and then by protamines. In humans, approximately 15% of the sperm DNA remains packaged by histones in sequence-specific areas. The histone variant H2B, member W, testis-specific (H2BFWT)...
Chromatin-remodeling factors regulate the establishment of transcriptional programs during plant development. Although 42 genes encoding members of the SWI2/SNF2 family have been identified in Arabidopsis thaliana, <10 have been assigned a precise function on the basis of a mutant phenotype, and none have been shown to play a specific role during the gametophytic phase of the plant life cycle. ...
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia in clinical practice. Unfortunately, the precise mechanisms and sensitive serum biomarkers of atrial remodeling in AF remain unclear. The aim of this study was to determine whether the expression of the transcription factors NF-AT3 and NF-AT4 correlate with atrial structural remodeling of atrial fibrillation and serum mar...
C-reactive protein (CRP) is a risk factor or biomarker for cardiovascular diseases, including hypertension. The present study investigated the functional importance of human CRP in hypertensive cardiac remodeling by a chronic infusion of angiotensin II (Ang II) into mice that express human CRP. Compared with the wild-type mice, although Ang II infusion caused an equally high systolic blood pres...
Nuclear actin family proteins, comprising of actin and actin-related proteins (Arps), are essential functional components of the multiple chromatin remodeling complexes. The INO80 chromatin remodeling complex, which is evolutionarily conserved and has roles in transcription, DNA replication and repair, consists of actin and actin-related proteins Arp4, Arp5, and Arp8. We generated Arp5 knockout...
