HALPIN, P. M.; HOFMANN, G. E.; Univ. of California, Santa Barbara; Univ. of California, Santa Barbara: Relationship between heat shock response and body temperature in natural population of intertidal mussels during spring Organisms must quickly respond to environmental changes at the physiological level. In the heat shock response (HSR), heat shock proteins (Hsps) are rapidly […]

JOHN-ALDER, H.B.*; CARSIA, R.V.; Rutgers Univ., New Brunswick; UMDNJ School of Osteopathic Medicine, Stratford: Inflence of the Testis on Adrenocortical Cell Function in Sceloporus undulatus (Eastern Fence Lizard) Adrenal steroidogenic cells from male Sceloporus undulatus undergo dramatic seasonal changes in sensitivity to ACTH. Here, we examine possible testicular influences on adrenocortical cell function. Intact (CON) […]

LANDRY, CA; MANNING, S; CHEEK, AO; Southeastern Louisiana University, Hammond; Gulf Coast Research Laboratory, Ocean Springs; Southeastern Louisiana University, Hammond: Hypoxia Affects Reproduction in Gulf Killifish, Fundulus grandis Hypoxia is a naturally occurring consideration of water quality. The longevity and range of low dissolved oxygen occurrences can be exacerbated by eutrophication, now listed as a […]

SELCER, Kyle W.; NESPOLI, Lisa; MANGUS, Lisa; Duquesne University: Estrogen Induction of Vitellogenin Protein and mRNA in Tiger Salamanders In oviparous vertebrates, estrogen stimulates the liver to produce the egg-yolk precursor protein vitellogenin. Knowledge of serum vitellogenin levels is valuable in studies of vertebrate reproductive cycles; furthermore, vitellogenin induction is now widely used as a […]

COX, Robert M; JOHN-ALDER, Henry B; Rutgers University: Energetic mechanisms for testosterone-mediated growth inhibition in male eastern fence lizards, Sceloporus undulatus Conceptual energetic models predict that growth will be traded off against other important functions (i.e., maintenance, activity, reproduction) when energy is limited, but the implications of sexual differences in such trade-offs with regard to […]

WEISS, S.L.; JENNINGS, D.H.; PAINTER, D.L.; MOORE, M.C.; Arizona State Univ, Tempe; Arizona State Univ, Tempe; Arizona State Univ, Tempe; Arizona State Univ, Tempe: Endocrine capacity of oviductal tissues of oviparous (Urosaurus ornatus, Sceloporus virgatus) and viviparous (S. Jarrovi) lizards Studies of the evolution of viviparity largely focus on specific mechanisms that allow for viviparous […]

FREAMAT, M.*; SOWER, S.A.; University of New Hampshire, Durham; University of New Hampshire, Durham: A Putative Gonadotropin Hormone Receptor from Sea Lamprey (Petromyzon marinus) Testes. The sea lamprey (Petromyzon marinus) is the only Agnathan in which the existence of an endocrine hypothalamo-pituitary-gonadal (HPG) axis has been clearly established. Knowledge of the HPG axis in lamprey […]

KRISTAN, D.M.*; AUSTAD, S. N.; California State University, San Marcos; University of Idaho: Whole animal longevity and cellular resistance to oxidative stress in primary kidney fibroblasts of birds and rodents Oxidative damage to DNA occurs during normal metabolism and the effects of this damage accumulate with age, making oxidative stress one of the foremost proximate […]

ORTH, ME*; MONCURE, KG; WILLIAMS, EE; Salisbury University; Salisbury University; Salisbury University: The comparative effects of DHA on T27A murine leukemia cells and CHSE and ZFL fish cells Docosahexaenoic acid (DHA) is the longest and most unsaturated of the omega 3 fatty acids commonly found in cell membranes. As a component of cell membranes, it […]
