Although basic fibroblast growth factor (bFGF/FGF-2) is found outside cells, it lacks a conventional signal peptide sequence; the mechanism underlying its export from cells is therefore unknown. Using a transient COS-1 cell expression system, we have identified a novel membrane-associated transport pathway that mediates export of FGF-2. This export pathway(More)
Valproic acid is commonly and effectively used in the treatment of idiopathic generalized epilepsies, including juvenile absence epilepsy. Although several adverse effects are associated with this drug, it has only rarely been known to exacerbate seizures. Similar to antiarrhythmic drugs aggravating particular arrhythmias, antiepileptic drugs can(More)
OBJECTIVE To investigate the prognostic importance of an identified putative underlying risk factor in patients undergoing surgery for intractable temporal lobe epilepsy (TLE). PATIENTS AND METHODS A retrospective study of 400 consecutive patients who underwent TLE surgery between December 21, 1987, and September 11, 1996, was performed. Demographic(More)
The rate-limiting enzyme for mevalonate synthesis in mammalian cells is 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Products of mevalonate synthesis are required for cell cycle progression as well as cell growth and survival. In tumor cells, HMG-CoA reductase is generally elevated because of attenuated sterol-mediated regulation of(More)
Previously we demonstrated that secondary products of plant mevalonate metabolism called isoprenoids attenuate 3-hydroxy-3-methylglutaryl coenzyme A reductase mRNA translational efficiency and cause tumor cell death. Here we compared effects of "pure" isoprenoids (perillyl alcohol and gamma-tocotrienol) and a "mixed" isoprenoid-genistein-on the PKB/Akt/mTOR(More)
To determine the localizing value of electroencephalography (EEG) for seizures during sleep versus seizures during wakefulness, we compared scalp EEG for 58 seizures that occurred during sleep with 76 seizures during wake in 28 consecutive patients with temporal lobe epilepsy. Regression analysis showed that seizures during sleep are 2.5 times more likely(More)
We used regression analysis to compare the semiologic features of temporal lobe seizures that occur during sleep (TLS-S) and wake (TLS-W) in the same patient. Most semiologic features correctly lateralized seizure activity during either sleep or wake. No significant differences were found between TLS-S and TLS-W in the 18 semiologic features analyzed.
