Genistein affects parathyroid gland and NaPi 2a cotransporter in an animal model of the andropause.
This study aimed to examine the effects of genistein on the structural and functional changes in parathyroid glands (PTG) and sodium phosphate cotransporter 2a (NaPi 2a) in orchidectomized rats. Sixteen-month-old Wistar rats were divided into sham-operated (SO), orchidectomized (Orx) and genistein-treated orchidectomized (Orx+G) groups. Genistein (30 mg/kg/day) was administered subcutaneously for 3 weeks, while the controls received vehicle alone. PTG was analyzed histomorphometrically, while the expressions of NaPi 2a mRNA/protein levels from kidneys were determined by real time PCR and Western blots. Serum and urine parameters were determined biochemically. The PTG volume in Orx rats was increased by 30% (p<0.05), compared to the SO group. Orx+G treatment increased the PTG volume by 35% and 75% (p<0.05) respectively, comparing to Orx and SO animals. Orchidectomy led to increment of serum PTH by 27% (p<0.05) compared to the SO group, Orx+G decreased it by 18% (p<0.05) comparing to Orx animals. NaPi 2a expression in Orx animals was reduced in regards to its abundance in SO animals, although it was increased in Orx+G group compared to the Orx. Phosphorus urine content of Orx animals was raised by 12% (p<0.05) compared to that for the SO group, while Orx+G induced a 17% reduction (p<0.05) in regards to Orx animals. Our study shows that Orx increases PTG volume and serum PTH level, while protein expression of NaPi 2a is reduced. Application of genistein attenuates the orchidectomy-induced changes in serum PTH level, stimulates the expression of NaPi 2a and reduces urinary Pi excretion, implying potential beneficial effects on andropausal symptoms.
