Ogut, Ozgur, Henk Granzier, and Jian-Ping Jin. Acidic and basic troponin T isoforms in mature fast-twitch skeletal muscle and effect on contractility. Am. J. Physiol. 276 (Cell Physiol. 45): C1162–C1170, 1999.—Developmentally regulated alternative RNA splicing generates distinct classes of acidic and basic troponin T (TnT) isoforms. In fast-twitch skeletal muscles, an acidic-to-basic TnT isofor...

Physiol. 276 (Heart Circ. Physiol. 45): H1641–H1646, 1999.—The present study addresses the hypothesis that CO produced from endogenous heme oxygenase (HO) can dilate newborn cerebral arterioles. HO-2 protein was ...

Jin, Lan, Lee Chao, and Julie Chao. Potassium supplement upregulates the expression of renal kallikrein and bradykinin B2 receptor in SHR. Am. J. Physiol. 276 (Renal Physiol. 45): F476–F484, 1999.—High potassium intake is known to attenuate hypertension, glomerular lesion, ischemic damage, and stroke-associated death. Our recent studies showed that expression of recombinant kallikrein by somati...

The vertebrate hypothalamus contains persistent radial glia that have been proposed to function as neural progenitors. In zebrafish, a high level of postembryonic hypothalamic neurogenesis has been observed, but the role of radial glia in generating these new neurons is unclear. We have used inducible Cre-mediated lineage labeling to show that a population of hypothalamic radial glia undergoes ...

Lutz, Peter L., and Liscia Manuel. Maintenance of adenosine A1 receptor function during long-term anoxia in the turtle brain. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R633–R636, 1999.—It has been established that adenosine has a critical role in the extraordinary ability of the turtle brain to survive anoxia. To further investigate this phenomenon we compared rat and turt...
