(Submitter supplied) A study of rat femoral fracture healing in young (6 weeks old at fracture), adult (26 weeks old at fracture), and old (52 weeks old at fracture) rats. Samples were collected at time of surgery (intact controls) and at 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after fracture. Samples were the mid third of the femoral length including the external callus, cortical bone and marrow elements. Fracture was stabilized with an intramedullary rod prior to fracture with a Bonnarens and Einhorn device. more...

(Submitter supplied) mRNA gene expression was measured in intact female Sprague-Dawley rats at 6 (young), 26 (adult) and 52 (older) weeks of age at the time of fracture. Samples were collected at 0, 0.4, 1, 2, 4, and 6 weeks after fracture. RNA from two rats were pooled for each Affymetrix Rat U34A array. Mid-shaft, simple, transverse left femoral fractures were induced after retrograde intramedullary rod fixation with a Bonnarens and Einhorn device. more...

(Submitter supplied) OBJECTIVE: To analyze genome-wide changes in chondrocyte gene expression in a surgically induced model of early osteoarthritis (OA) in rats, to assess the similarity of this model to human OA, and to identify genes and mechanisms leading to OA pathogenesis. METHODS: OA was surgically induced in 5 rats by anterior cruciate ligament transection and partial medial meniscectomy. Sham surgery was performed in 5 additional animals, which were used as controls. more...

(Submitter supplied) mRNA used for the analysis of these microarrays were previously analyzed for 34 genes by reverse transcription - polymerase chain reaction in Desai BJ et al., J.Orthop.Trauma 17: 689-698, 2003. These two data sets were subsequently studied to compare the results from these two different methods for mRNA quantitation. The comparison was publised in "Comparison of mRNA gene expression by RT-PCR and DNA microarray" by W. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Mechanical loading is a key determinant of bone mass, geometry and strength and is essential to maintain optimal skeletal health. We hypothesized that spontaneous low-impact exercise would affect global gene transcript levels in cortical bone of growing rats. We used RNA-Seq to analyse the transcriptome of the femoral mid-diaphysis in pre-pubertal male rats that were assigned to one of three exercise groups for 15 days: control (CON); bipedal stance (BPS); and wheel exercise (WEX). more...
