Project description:Purpose: To investigate the effect of transcorneal electrical stimulation (TES) on the retina of wildtype Brown Norway (BN) rats by gene expression profiling. Methods: TES was applied to BN adult wildtype rat retina in vivo for 1h (1ms biphasic pulses at 20Hz; current: 200 µA). RNA was isolated, processed and used for microarray-based expression profiling 4hrs after initial TES. An expression profile was generated for genes differentially expressed at 4hrs after TES vs. sham stimulated animals using a fold change cutoff of 1.2. We validated the profile by real-time quantitative reverse transcription-polymerase chain reaction (qPCR). In addition, the application of TES was verified at the structural and functional level. Results: Transcriptome changes associated with TES vs. sham stimulated BN wildtype retina were identified. 490 genes were differentially expressed in TES and included well-known genes as well as a large number of novel genes. Electrophysiological recordings showed physiological retinal function after TES and structural in vivo and ex vivo studies revealed intact retinal layers. Conclusion: Our results demonstrate that TES applied to the retina of wildtype BN rats induce a variety of transcriptome level changes and may help to understand the mechanisms underlying TES. In addition TES has no negative effect on structure and function of wildtype BN retina 24hrs after application.

Project description:Major urinary proteins (MUP) are the major component of the urinary protein fraction in house mice (Mus spp.) and rats (Rattus spp.). The structure, polymorphism and functions of these lipocalins have been well described in the western European house mouse (Mus musculus domesticus), clarifying their role in semiochemical communication. The complexity of these roles in the mouse raises the question of similar functions in other rodents, including the Norway rat, Rattus norvegicus. Norway rats express MUPs in urine but information about specific MUP isoform sequences and functions is limited. In this study, we present a detailed molecular characterization of the MUP proteoforms expressed in the urine of two laboratory strains, Wistar Han and Brown Norway, and wild caught animals, using a combination of manual gene annotation, intact protein mass spectrometry and bottom-up mass spectrometry-based proteomic approaches. Detailed sequencing of the urinary MUP isoforms reveals a less complex pattern of primary sequence polymorphism in the rat than the mouse. However, rat MUPs exhibit added complexity in the form of post-translational modifications, including the phosphorylation of Ser4 in some isoforms, and exoproteolytic trimming of specific isoforms.

Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.

Project description:Five ovariectomized (OVX) Brown Norway rats (Charles Rivers Laboratories, Wilmington, DE, USA) weighing 200-250 g received 10 µL of 17β-estradiol (E2) eye drops once daily in both eyes for three weeks [20]. The eye drops contained 0.1% (w/v) E2 in saline vehicle containing 20% (w/v) 2-hydroxypropyl-β-cyclodextrin. Five OVX control rats received 10 µL of this vehicle as eye drops for the same dosing regimen and duration. After 24 h of the last treatment, the animals were euthanized by CO2 overexposure, and their eyes were immediately enucleated followed by the isolation of the retina. The tissue samples were rinsed with saline and, then, blotted dry for preparation to label-free shotgun proteomic analyses. All procedures involving animals were reviewed and approved by the Institutional Animal Care and Use Committee at the University of North Texas Health Science Center before the initiation of the studies (approval number: 2018-0028).
