Analysis of altered mRNA expression profiles in the genetic hypercalciuric stone-forming (GHS) rat compared to normal SD rat

ABSTRACT: Urolithiasis is a common desease to human beings, and idiopathic hypercalciuria (IH) is an important risk factor of calcium urolithiasis, previous studies strongly suggested that the decreased tubular Ca2+ reabsorption played a key role of hypercalciuria. However,the molecular mechanism of IH-urolithiasis formation is still not completely elucidated. GHS rat is regarded as an ideal animal model of calcium urolithiasis, reveals many identical pathophysiologic characteristics with IH patients . We analyzed mRNA expression profiles of the kidney of GHS rat in order to find out the target genes and signaling pathways in the pathogenesis of IH. Overall design: The colony of GHS rats were created by the selective breeding of male and female SD rats with the highest 24 hour urine excretions (doi: 10.3390/ijms160716313). In the 28 generation, GHS rats have stabilized excreted significant higher level of urine calcium than wild-type normal SD rats, and reveals many identical pathophysiologic characteristics with IH patients, such as normal serum Ca2+, hypercalciuria, elevated intestinal Ca2+ resorption and a tendency to lose calcium from the bone. This present study examined the mRNAs expression of three pairs of GHS rats’ kidneys with normal SD rats by microarrays.

Background. MicroRNAs (miRNAs) influence a variety of biological functions by regulating gene expression post-transcriptionally. Aberrant miRNA expression has been associated with many human diseases. Urolithiasis is a common disease, and idiopathic hypercalciuria (IH) is an important risk factor for calcium urolithiasis. However, miRNA expression patterns and their biological functions in urolithiasis remain unknown. Methods and Results. A multi-step approach combining microarray miRNA and mRNA ...[more]

Project description:The long-term effects of neonatal intermittent hypoxia (IH), an accepted model of apnea-induced hypoxia, are unclear. We have previously shown lasting “programming” effects on the HPA axis in adult rats exposed to neonatal IH. We hypothesized that neonatal rat exposure to IH will subsequently result in a heightened inflammatory state in the adult. Rat pups were exposed to normoxia (control) or six cycles of 5% IH or 10% IH over one hour daily from postnatal day 2 – 6. Plasma samples from blood obtained at 114 days of age were analyzed by assessing the capacity to induce transcription in a healthy peripheral blood mononuclear cell (PBMC) population and read using a high-density microarray. The analysis of plasma from adult rats previously exposed to neonatal 5% IH vs. 10% IH resulted in 2,579 significantly regulated genes including increased expression of Cxcl1, Cxcl2, Ccl3, Il1a, and Il1b. We conclude that neonatal exposure to intermittent hypoxia elicits a long-lasting programming effect in the adult resulting in an upregulation of inflammatory-related genes. Apnea is the most common cause of neonatal hypoxia affecting about 50% of preterm births (30 – 31 weeks), usually due to immature respiratory development. Upregulation of inflammatory genes and pathways in children 7 – 10 years of age has been shown, and there is a known increased risk of insulin resistance in adulthood when the fetus is exposed to maternal hypoxia, but the mechanism is unclear. The long-term metabolic, endocrine, and immunological effects of neonatal intermittent hypoxia (IH) exposure, an accepted model of apnea-induced hypoxia, have not been thoroughly evaluated. Recent studies in rats have shown that perinatal IH exposure can result in oxidative stress, causing a permanent immune response subsequently resulting in features of diabetes mellitus. We have previously examined adult rats exposed to neonatal intermittent hypoxia and perinatal continuous hypoxia, and have found lasting “programming” effects on the HPA axis. We now assess the long term effects of an accepted model of apnea-induced hypoxia using a validated transcriptional bioassay to study the extracellular milieu of adult rats exposed to neonatal intermittent hypoxia. We hypothesize that exposure to neonatal intermittent hypoxia will result in an increased inflammatory state in the adult as a result of long-lasting programming. Sprague-Dawley (SD) rat pups were treated with neonatal normoxia (21% O2, control), 5% intermittent hypoxia (IH), or 10% IH on postnatal days (PD) 2-6, daily over 1 hr. They were reared normally by birth dams and weaned at PD22. Males were allowed to mature and sacrificed at age PD114 after an overnight fast. Whole blood collected by decapitation into tubes with EDTA, and plasma saved for further analysis. Two adult (~180 day) male Brown Norway (BN) rats served as PBMC donors. Cells were incubated with 20% plasma that was either autologous BN (self-control), or one of 3 pools: a) SD normoxic N=8, b) SD 5% IH treated N=5, and c) SD 10% IH N=3.

Project description:Immune modulation has been recognized as an effective anti-osteoporosis strategy since the pivotal role of the RANK/RANKL/OPG signaling in bone metabolism and remodeling was discovered. To investigate the potential preventive and/or therapeutic effects of immune modulator protein Ling Zhi-8 (LZ-8) on osteoporosis, the osteoporosis animal model was established in Wistar rats by intramuscular injection of dexamethasone (DEX), namely glucocorticoids-induced osteoporosis (GIOP) rat model. To investigate the potential preventive effect of rLZ-8 on GIOP, we co-treated the rats with DEX and rLZ-8 intraperitoneally during the GIOP modeling stage and analyze the bone mass measured by bone mineral content (BMC) and bone mineral density (BMD), as well as levels of phosphorus (Pi), calcium (Ca2+) and hydroxyproline (HOP) in femur of GIOP rats. Consistently, all results suggested that rLZ-8 could prevent bone loss in the femurs of GIOP rats. Through analyzing the trabeculae morphology and the trabeculae amount by H&E staining, we found rLZ-8 could also improve the structural deterioration in femurs of GIOP rats. In order to further verify the results and its mechanism obtained from bone analysis, multiple biomarkers, including minerals metabolism (Pi and Ca2+), bone formation markers (osteocalcin, ALP and IGF-1), bone resorption markers (TRACP5b, CTX-1 and HOP), cytokines (IL-1?, IL-6 and TNF-?), oxidative stress indicators (GSH-px, SOD and MDA) and hormone molecules (testosterone, estradiol, calcitonin and parathyroid hormone) have been detected in serum or urine of rats. Results of these biomarkers in serum or urine confirmed rLZ-8's protective effect in GIOP. Through analyzing the relative expression level of OPG and RANKL in femurs via western blot, we foundrLZ-8 could increase OPG/RANKL ratio which could impede osteoclastogenesis process. To test the potential therapeutic effect of rLZ-8 on successfully generated GIOP rats, we administrated rLZ-8 to rats for three weeks starting from the ending day of 7 weeks treatment of DEX. We found rLZ-8 could also reverse the bone loss in GIOP rats. Through the BWs and organ coefficient analysis, we found rLZ-8 has little toxicity to the rats. Our results suggested that rLZ-8 may be developed into promising anti-osteoporosis drug with both preventive and therapeutic properties.
