Perturbation of cardiolipin (CL) synthesis in yeast cells leads to defective respiratory chain function and mitochondrial DNA loss, both of which have been implicated in aging in mammals. The availability of yeast CL mutants enabled us to directly investigate the role of CL synthesis in aging. In this report, we show that the replicative life span of(More)
The cytochrome P450 epoxygenase, CYP2J2, converts arachidonic acid to four regioisomeric epoxyeicosatrienoic acids (EETs). We found recently that this enzyme is dramatically up-regulated in a variety of established human carcinoma cell lines and in human cancerous tissue and promotes the neoplastic phenotype. In the present study, we tested the hypothesis(More)
We have previously shown that mutants in the cardiolipin (CL) pathway exhibit temperature-sensitive growth defects that are not associated with mitochondrial dysfunction. The pgs1Delta mutant, lacking the first enzyme of the CL pathway, phosphatidylglycerolphosphate synthase (Pgs1p), has a defective cell wall due to decreased beta-1,3-glucan (Zhong, Q.,(More)
Mesenchymal stem cells (MSCs) have been successfully used for the treatment of experimental stroke. However, the neurorestorative mechanisms by which MSCs improve neurological functional recovery are not fully understood. Endogenous cell proliferation in the subventricular zone (SVZ) after stroke is well known, but most of newly formed cells underwent(More)
MicroRNA-34a (miR-34a), a transcriptional target of p53, is a well-known tumor suppressor gene. Here, we identified Fra-1 as a new target of miR-34a and demonstrated that miR-34a inhibits Fra-1 expression at both protein and messenger RNA levels. In addition, we found that p53 indirectly regulates Fra-1 expression via a miR-34a-dependant manner in colon(More)
Insulin-like growth factor binding protein 2 (IGFBP-2) is a malignancy-associated protein measurable in tumors and blood. Increased IGFBP-2 is associated with shortened survival of advanced glioma patients. Thus, we examined plasma IGFBP-2 levels in glioma patients and healthy controls to evaluate its value as a plasma biomarker for glioma. Plasma IGFBP-2(More)
OBJECTIVE To analyze the clinical characteristics of ovarian masses in children and adolescents. MATERIALS AND METHODS We performed a retrospective analysis of patients less than 20 years of age who were treated at the Obstetrics and Gynecology Hospital of Fudan University between March 2003 and January 2012. Medical records were reviewed for age at(More)
Gliomas arising in the brainstem and thalamus are devastating tumors that are difficult to surgically resect. To determine the genetic and epigenetic landscape of these tumors, we performed exomic sequencing of 14 brainstem gliomas (BSGs) and 12 thalamic gliomas. We also performed targeted mutational analysis of an additional 24 such tumors and genome-wide(More)
Diabetic neuropathy (DNP) is the most common chronic complication of diabetes. Elevated free fatty acids (FFAs) have been recently recognized as a major cause of nervous system damage in diabetes. P2X receptors play a primary role in regulation of neuronal interleukin (IL)-6 release, which is of paramount relevance to the functional changes of nerve system.(More)
UNLABELLED A burn is a severe injury, and the resulting pain can be very significant. Currently, opioids are the primary method of pain management, but these drugs have side effects; thus, it is of prime focus to research the mechanisms of pain formation and analgesic drugs. OBJECTIVE To investigate the effects of tetramethylpyrazine (TMP) on burn pain(More)
