Melatonin is produced by the pineal gland and regulates various physiological processes including osteoblast differentiation and bone formation. Bone sialoprotein (BSP) is a mineralized connective tissue-specific protein expressed in the early stage of cementum and bone mineralization. To elucidate the effects of melatonin on human BSP gene expression, we utilized human Saos2 osteoblast-like ce...

Primary pulmonary myxoid sarcoma (PPMS), classified as low to intermediate grade malignant myxoid endobronchial tumor, is rarely reported. Most reported cases occurred in lung parenchyme with an endobronchial component. Herein, we report a case of PPMS in a 29-year-old woman that developed in a major fissure of the left lung without parenchymal invasion. Histopathologically, the diagnosis was c...

MicroRNAs are involved in regulation of the central nervous system (CNS) development, and miR-181d highly expressed mature neurons. CREB is many signal pathways converged point hippocampal neurons, it plays a crucial role learning memory. In this study, we detected negative relationship between CREB1 protein expression lewis rat hippocampus development. And bioinformatic analysis showed that, m...

The programme of Epstein-Barr virus (EBV) gene expression that leads to virus-induced growth transformation of resting B lymphocytes is initiated through activation of the BamHI W promoter, Wp. The factors regulating Wp, and the basis of its preferential activity in B cells, remain poorly understood. Previous work has identified a B cell-specific enhancer region which is critical for Wp functio...

Diffuse malignant mesothelioma (DMM) is a tumor of serosal membranes with propensity for progressive local disease. Because current treatment options are largely ineffective, novel therapeutic strategies based on molecular mechanisms and the disease characteristics are needed to improve the outcomes of patients with this disease. Akt kinase interacting protein 1 (Aki1; Freud-1/CC2D1A) is a scaf...

Fibroblast growth factor 2 (FGF2), a member of the FGF family, positively regulates bone formation and osteoblast differentiation. Bone sialoprotein (BSP) is highly expressed during early bone formation and may play a role in primary mineralization of bone. In the present study, FGF2 (10 ng/mL) was found to increase the levels of Runx2 and BSP mRNA at 3 and 12 h in human osteoblast-like Saos2 c...

MicroRNAs play extensive roles in cellular development. Analysis of the microRNA expression pattern during intestinal cell proliferation in early life is likely to unravel molecular mechanisms behind intestinal development and have implications for therapeutic intervention. In this study, we isolated mouse intestinal crypt cells, examined the differences in microRNA expression upon IGF-1 stimul...

Smaller-scale evaluations suggest that common genetic variation in candidate genes related to immune function may predispose to the development of non-Hodgkin lymphoma (NHL). We report an analysis of variants within genes associated with immunity and inflammation and risk of NHL using a panel of 9412 single-nucleotide polymorphisms (SNPs) from 1253 genes in a study of 458 patients with NHL and ...

To clarify the molecular basis of human TLR9 (hTLR9) gene expression, the activity of the hTLR9 gene promoter was characterized using the human myeloma cell line RPMI 8226. Reporter gene analysis and EMSA demonstrated that hTLR9 gene transcription was regulated via four cis-acting elements, cAMP response element, 5'-PU box, 3'-PU box, and a C/EBP site, that interacted with the CREB1, Ets2, Elf1...

The prostaglandin E2 receptor, EP2 (E-prostanoid 2), plays an important role in mice glomerular MCs (mesangial cells) damage induced by TGFβ1 (transforming growth factor-β1); however, the molecular mechanisms for this remain unknown. The present study examined the role of the EP2 signalling pathway in TGFβ1-induced MCs proliferation, ECM (extracellular matrix) accumulation and expression of PGE...
