There was no significant difference in the four groups in adenyl cyclase activity stimulated by forskolin, NaF, and isoproterenol. The decrease in PTH-induced adenyl cyclase activity was associated with an approximately 2-fold increase in PTH/PTHrp receptor mRNA expression in the kidneys of the D-...
Renal responsiveness to pth in fetuses mothers and newborns kidneys in the ratThe psychrotrophic bacterium Pseudomonas fluorescens is a milk contaminant known to secrete a lipase that is a nuisance for the dairy industry but may have a biotechnological interest. Strain MFO secretes this enzyme upon ...
1,2PTH, together with vitamin D and calcitonin, brings about mobilization ofcalcium and phosphate from the skeletal system and increases the uptakeof calcium in the intestine and the excretion of phosphate via the kidneys.The constancy of the blood calcium level is ensured by the interaction of...
PTH modulates bone turnover by binding to the PTH/PTH-related peptide (PTHrP) type 1 receptor (PPR), a G-protein-coupled receptor highly expressed in bone and kidneys. Osteocytes, the most abundant cells in adult bone, also express PPR. However, the physiological relevance of PPR signaling ...
Parathyroid hormone (PTH) plays a critical role in controlling calcium, phosphate and calcitriol (active vitamin D) levels in the blood and bone. Through its primary actions, PTH directly involves the kidneys, bone and other organs in maintaining key biological functions. Hypoparathyroidism (hypo...
and headache. Patients often experience decreased quality of life, and, over the long term, this complex disorder can increase risk of major complications, such as calcium deposits in the brain, blood vessels, eye, and other soft tissues – including the ...
Which hormone, produced by the adrenal cortex, increases sodium reabsorption in the kidneys? Which of the following is not a hormone released from the anterior pituitary? a. prolactin inhibiting hormone b. follicle stimulating hormone c. luteinizing ho...
This suggests that 25(OH)D3 is involved in the early stages of fracture repair and that there is some form of physiological communication between the fractured bone and the kidneys leading to an increase of renal 24-hydroxylase and the circulating concentration of this metabolite [9]. In mice...
