Background and Objective: Gliomas are the most common primary brain tumors. Despite therapeutic advances, the majority of gliomas do not respond to either chemo or radiotherapy. CD117, the gene product of c-kit has been expressed in cells of glial tumors. Because gastrointestinal stromal tumors (GISTs) that express CD117 respond dramatically to treatment with tyrosine kinase inhibitors, ide...

Mutations in PARK7/DJ-1 are associated with autosomal recessive, early onset Parkinson disease (PD). DJ-1 is an atypical peroxiredoxin-like peroxidase that may act as a redox-dependent chaperone and a regulator of transcription. Here we show that DJ-1 plays an essential role in the expression of rearranged during transfection (RET), a receptor for the glial cell line-derived neurotrophic factor...

Glial cell line-derived neurotrophic factor (GDNF) is a growth factor promoting the survival of several neuronal populations in the central, peripheral and autonomous nervous system. Outside the nervous system, GDNF functions as a morphogen in kidney development and regulates spermatogonial differentiation. GDNF exerts its roles by binding to glial cell line-derived neurotrophic factor receptor...

Tumors of the central and peripheral nervous system were induced in rats with ethylnitrosourea. Many of these tumors were transplanted in syngeneic recipients, and several cell lines were derived from them. An antiserum raised against one such cell line in C3H mice defined two cell surface antigens in cytotoxicity tests. One, the common antigen, was present on rat brain and embryonic tissues an...

Acupuncture for the treatment of Parkinson's disease has a precise clinical outcome. This study investigated the effect of electroacupuncture at Fengfu (GV16) and Taichong (LR3) acupoints in rat models of Parkinson's disease induced by subcutaneous injection of rotenone into rat neck and back. Reverse transcription-PCR demonstrated that brain-derived neurotrophic factor and glial cell line-deri...

BACKGROUND Several shared common gene networks participate in development of interstinal ganglia and also nephron formation; the glial cell line-derived neurotrophic factor/Ret/glial cell line-derived neurotrophic factor receptor gene network is particularly important. CASE PRESENTATION We encountered a patient with total colonic aganglionosis as well as right renal agenesis and oligomeganeph...

The glial fibrillary acidic protein (GFAP) is a glial-specific intermediate filament protein, which is expressed in astrocytes in the central nervous system, as well as in astrocytoma cell lines. To investigate the function of GFAP, we have studied the human astrocytoma cell line, U251, which constitutively expresses GFAP and vimentin in the same 10-nm filaments. These cells respond to neurons ...
