Analyzing the Interactions Between Xenopus tropicalis MC2R, MC5R, and the MRAPs: Modeling the Regulation of Frog Interrenal Cells
… of Melanocortin 2 Receptor (MC2R) in adrenal/interrenal glucocorticoid secretion has been well documented in many organisms. Studies in mammals have shown that in the adrenal gland two melanocortin receptors and two melanocortin receptor accessory proteins are expressed: MC2R, MC5R, MRAP, and …

Characterization of Andrenocortical Tissue Morphology, Histology, and Steroid Synthesis Among Finetooth (<i>Carcharhinus isodon</i>), Blacktip (<i>Carcharhinus limbatus</i>), Atlantic Sharpnose (<i>Rhizoprionodon terraenovae</i>), and Bonnethead (<i>Sphyrna tiburo</i>) Sharks
<p>Adrenocortical (interrenal) tissue is composed of steroidogenic cells that produce corticosteroids involved in the stress response and hydromineral balance. Previous research characterizing the elasmobranch interrenal suggests that the number of interrenal bodies that produce the single primary …

The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish
… is released via the hypothalamic-pituitary-interrenal (HPI) axis. This thesis examined the premise that social status, maternal experience, and reproductive status affect HPI axis function in fish. Social stress in juvenile rainbow trout (Oncorhynchus mykiss) chronically elevates circulating …

Analyzing the Interaction Between Melanocortin 5 Receptor, Melanocortin Receptor Accessory Protein 1, and Melanocortin 2 Receptor in Rainbow Trout
… role in Hypothalamic-Pituitary-Adrenal/Interrenal axis activation. This research demonstrated that rtMC5R can be successfully expressed and functionally activated in CHO cells and, in a manner similar to mammals, α-MSH is the preferred ligand for rtMC5R. The presence of MRAP1 does not …

Differential gene expression analysis reveals functional roles of cryptic orange-pigmented organ in the colorless head kidney of Antarctic icefishes
… indicate it performs functional roles of the interrenal tissue cells – the teleost homolog of the tetrapod adrenal cortex but are normally dispersed among the teleost head kidney tissue. Transcription of many cytochrome P450 enzymes participating in steroidogenesis were upregulated, …

The Effects of Neuroendocrine Stress on Larval Development
… activation of the hypothalamic-pituitary-adrenal/interrenal (HPA/I) axis speeds their development, allowing them to metamorphose and escape suboptimal aquatic habitat. Accelerated development comes at a cost, the glucocorticoid (GC) hormones secreted by the HPA/I axis affect other systems such as …

Bienestar animal en el cultivo de dorada (Sparus aurata): Mecanismos de atenuación del estrés
… regulación del sistema hipotalámico-hipofisario-interrenal (HPI), respecto a niveles de expresión de los principales factores a nivel central (cerebro e hipófisis) y periférico (riñón cefálico), así como los niveles de cortisol en plasma. Además, se han determinado las modificaciones en la …

The effects of herbicide treatment on a reservoir ecosystem
… changes due to treatment were found in goldfish interrenal, thyroid, hernatopoietic or sensory tissues; gill lesions occured at maximum concentrations. The mixture field concentration did not cause avoidance in goldfish. Higher concentrations of diquat (1.1 mg/liter) and the mixture (1.1 mg/liter …

Effects of Pre-Release Physical Stressors on Post-Release Success of Hatchery-Reared Spotted Seatrout
… of down-regulation of the Hypothalamic-Pituitary-Interrenal (HPI) axis. For 48-dph fish in the cage study, survival was high and similar in control and experimental groups, but experimental fish were shorter, lighter, and of lower K than control fish. For 80-dph fish, fewer experimental fish …

Physiological and Cellular Responses Used By Lake Whitfish (Coregonus Clupeaformis) in Response to Thermal and Hypoxic Stress at Different Points in Development
… the development of the hypothalamus-pituitary-interrenal axis (HPI-axis) and two key cellular stress responses, the heat shock response (HSR) and hypoxia response, in lake whitefish (Coregonus clupeaformis) at several life-stages, to understand when these responses could be activated in …

Identification and Characterization of Developmentally Regulated Components of the Stress Axis in Petromyzon Marinus
… pituitary (HP) axes, specifically the HP interrenal (HPI) axis in fish. A functional HPI axis has recently been suggested in the lamprey species Petromyzon marinus, a member of the ancient vertebrate superclass agnatha, by identification of pituitary and inter-renal components …

The neuroendocrine and molecular mechanisms underlying stress-induced maternal effects in the threespine stickleback
