Recent evidence has suggested that microglial activation plays an important role in the pathogenesis of depression. Activated microglia can secrete various pro-inflammatory cytokines and neurotoxic mediators, which may contribute to the development and maintenance of depression. Thus, inhibition of microglial activation may have a therapeutic benefit in the(More)
AIMS To investigate whether Oct4, Sox2 and Nanog, three core regulatory factors maintaining pluripotency and self-renewal of embryonic stem cells (ESCs), are coexpressed in human gliomas, and whether their expression might be linked to carcinogenesis and the formation of cancer stem cells (CSCs). METHODS AND RESULTS Forty cases of human glioma were(More)
Diets rich in SFA have been implicated in Alzheimer's disease (AD). There is strong evidence to suggest that microglial activation augments the progression of AD. However, it remains uncertain whether SFA can initiate microglial activation and whether this response can cause neuronal death. Using the BV-2 microglial cell line and primary microglial culture,(More)
Sustaining proliferative signaling is one of the hallmarks of cancer. Granulocyte-colony stimulating factor (G-CSF), a hematopoietic growth factor that controls proliferation and differentiation of neural stem cells, may contribute to the development of glioma. In the present study, we evaluated the expression of G-CSF and its receptor (G-CSFR) in various(More)
BACKGROUND The etiology of most premature ovarian failure (POF) cases is usually elusive. Although genetic causes clearly exist and a likely susceptible region of 8q22.3 has been discovered, no predominant explanation exists for POF. More recently, evidences have indicated that mutations in NR5A1 gene could be causative for POF. We therefore screened for(More)
Elevated plasma free fatty acid (FFA) level is common in many pathological conditions, including neurological disorders, and their deleterious effects on various cells have been well documented. However, it remains to be investigated whether elevated FFAs would have a direct effect on neural stem cells (NSCs). Here, we reported that palmitic acid (PA)(More)
Melatonin, an indolamine produced and secreted predominately by the pineal gland, exhibits a variety of physiological functions, possesses antioxidant and antitumor properties. In this study, we have shown that pharmacologic concentration (1mm) of melatonin significantly reduced cell migration and invasion of T98G and U251 glioma cells after 24-hr treatment(More)
It has become increasingly clear that there are notable parallels between normal development and tumorigenesis. Glioma is a classic model that links between tumorigenesis and development. We evaluated the expression of GRIM-19, a novel gene essential for normal development, in various grades of gliomas and several human glioma cell lines. We showed that(More)
The POU family transcription factor OCT4 is required for maintaining the pluripotency of embryonic stem cells and for generating induced pluripotent stem cells. Although OCT4 is clearly shown to be expressed in some pluripotent germ cell tumours, its expression in human somatic tumours remains controversial. Some studies have shown that OCT4 is expressed in(More)
OBJECTIVE To determine whether plasma microRNAs (miRNAs) are differentially expressed between women with and without premature ovarian failure (POF), and to uncover the association of miRNAs with risk of POF. DESIGN Microarray with real-time polymerase chain reaction validation. SETTING University hospital. PATIENT(S) A total of 140 individuals with(More)
