Quantitative proteomics analysis reveals XDH related with ovarian oxidative stress in-volved in broodiness of geese

ABSTRACT: In this study, we screened the key proteins through the detection of antioxidant level of ovary combined with proteomic analysis to reveal the mechanism of goose broodiness and provide a new perspective to enhance the egg production performance.

Studies have demonstrated significant alterations in ovarian oxidative stress levels, ovarian degeneration, and follicular atresia during the broody period in geese. The results of this study showed that during the broody period, geese exhibited degraded ovarian tissues, disrupted follicular development, a thinner granulosa cell layer, and lower levels of ovarian hormones E2, P4, and AMH. Antioxidant activity (GSH, CAT, SOD, T-AOC, and the content of H<sub>2</sub>O<sub>2</sub>) and the mRNA expr ...[more]

Project description:Interpretation of toxicogenomic experiments conducted with ovary tissue from asynchronous-spawning small fish species are complicated by background variation in the relative abundance and proportion of follicles at different stages within the ovary tissue sample. This study employed both real-time quantitative PCR and a 15,000 gene oligonucleotide microarray to examine variation in the fathead minnow (Pimephales promelas) ovarian transcriptional profile as a function of quantitative and qualitative differences in ovarian histology. Multiple lines of evidence supported the conclusion that variation in the transcriptional profile was primarily dependent on the relative abundance of previtellogenic versus vitellogenic follicles in the ovary tissue. Due to the relatively small proportions of mature ovulated follicles or atretic follicles in the overall follicle population, few putative molecular markers of maturation, ovulation, or atresia could be identified. However, among the 460 differentially expressed genes identified in the study, targets including HtrA serine peptidase 3 (htra3), tissue inhibitor of metalloproteinase 3 (timp3), aquaporin 8 (aqp8), transgelin 2 like (tagln2), Nedd4 family interacting protein 2 (ndfip2), chemokine ligand 12a (cxcl12a), midkine related growth factor (mdka), and jagged 1b (jag 1b) exhibited responses and functional properties that support them as candidate molecular markers of significant shift in gross ovarian stage. Overall, results of this study provide insights into background variation in ovary transcript profiles that should aid and enhance the interpretation of toxicogenomic data generated in experiments conducted with small, asynchronous spawning fish species. Relative abundance of approximately 15,000 RNA transcripts in 26 ovary samples and 4 expelled oocyte (egg) samples, representing the five different histoclasses defined for the present study, was evaluated using fathead minnow oligonucleotide microarrays. Fathead minnow 15,000 gene arrays were purchased from Agilent (Palo Alto, CA, USA). The Agilent one-color microarray hybridization protocol (One-Color Microarray-Based Gene Expression Analysis, version 5.7, Agilent Technologies, Palo Alto, CA) was used for microarray hybridizations following the manufacturerM-bM-^@M-^Ys protocol and recommendations. One ug of total RNA was used for all hybridizations. cDNA synthesis, cRNA labeling, amplification and hybridization were performed following the manufacturerM-bM-^@M-^Ys kits and protocols (Quick Amp Labeling kit; Agilent, Palo Alto, CA). An Axon GenePixM-BM-. 4000B Microarray Scanner (Molecular Devices Inc., city, state) was used to scan microarray images at 5 M-NM-<m resolution.
