COMPARISON OF RABBIT SEMINAL PLASMA PROTEOME BETWEEN GENETIC LINES AND SEASONS

ABSTRACT: Seminal plasma contributes to the safe environment for sperm maturation, sperm viability and fertilization in mammals (Kumar 2013). Moreover, seminal plasma is a promising source for the study of potential reproductive biomarkers, because it is a complex mixture of secretions from testis, epididymis and male accessory sex glands (González-Cadavid et al. 2014). The protein composition of mammalian seminal plasma varies among species, and has important effects on sperm function (Mortarino et al. 1998). In rabbits, seminal plasma has a positive effect in maintaining sperm motility and viability during in vitro storage (Castellini et al. 2000). To study proteins on a large scale, the application of a proteomic approach is mandatory (Dietrich 2014). Rabbit seminal plasma proteome has been proved different between rabbit genetic line A (maternal) and R (growth) (Viudes-de-Castro et al. (2004), Safaa et al. (2008), Casares-Crespo 2016) and between seasons (Casares-Crespo 2016). In these previous studies a traditional 1 dimension polyacrylamide gel was done, identifying only major proteins visible after Coomassie Colloidal Blue staining and obtaining the relative quantity of these protein bands. On the contrary, new approaches such as liquid chromatography in-gel or in-solution digestion coupled with mass spectrometric analysis are a powerful, yet relatively uncomplicated strategy to identify and characterize proteins. Mass spectrometry-based proteomics has become the tool of choice for identifying and quantifying the proteome of an organism (Karpievitch 2010). Therefore, the present study was conducted to describe the seminal plasma proteome of rabbits, compare the differentially expressed seminal plasma proteins between genetic lines A and R and study the effect of season in rabbit seminal plasma proteome.

The present study was conducted to characterise rabbit seminal plasma proteins (SP proteins) focusing on the influence of the genetic origin and seasonality. In addition, β-NGF protein quantity in SP was determined. Semen samples were recovered from January to December 2014 using 6 males belonging to genotype A and six from genotype R. For each genotype, one pooled sample at the beginning, middle and end of each season was selected to develop the experiment. A total of 24 pools (3 for each seaso ...[more]

Project description:A greater understanding of the proteins involved in reproduction can benefit animal production. New advances in proteomics are having a major impact on our understanding of how spermatozoa acquire their capacity for fertilization [1]. Sperm proteomics aims at the identification of the proteins that compose the sperm cell and the study of their function [2]. The sperm cell is one of the most highly differentiated cells and is composed of a head with a highly compacted chromatin structure and a large flagellum with midpiece that contains the required machinery for movement and therefore to deliver the paternal genetic and epigenetic content to the oocyte [3]. By being so highly differentiated, spermatozoa are advantageous cells to study proteomics of specific compartments such as the membrane, which basically is the area of major importance for its role in interacting with the surroundings and the oocyte [4]. The fusion of a sperm and an oocyte is a sophisticated process that must be preceded by suitable changes in the sperm's membrane composition [5]. Recent studies of spermatozoa from the proteomic point of view have allowed the identification of different proteins in spermatozoa that are responsible for the regulation of normal/defective sperm functions [6]. While several techniques are available in proteomics, LC-MS based analysis of complex protein/peptide mixtures has turned out to be a mainstream analytical technique for quantitative proteomics [7]. Using this method, detailed proteomic data are now available for human [8], macaque [9,10], mouse [11], rat [12], bull [13-15], stallion [16], fruit fly [17], Caenorhabditis elegans [18], carp [19], rainbow trout [20], mussel [21], ram [22], honeybee [23] and rooster [24] sperm membrane proteins. Rabbit (Oryctolagus cuniculus) is an important mammalian species worldwide, being at the same time of commercial interest and a research model animal. European rabbit meat production is approximately 500 thousand tons, corresponding to a 30% share of world production [25]. Besides, rabbits account for the seventh highest number of animals slaughtered per year in the European Union-27, with 347,603 × 1000 head in 2014 [26]. In a previous work, we identified and quantified rabbit seminal plasma proteins between two different genotypes [27], concluding the clear effect of genotype in the abundance of certain seminal plasma proteins. However, it is unknown at present whether these differences also exist at sperm proteome level. Therefore, the aim of the present study was to characterise rabbit sperm membrane proteins through NanoLC-MS/MS analysis focusing on the influence of the genetic origin.

Project description:Male factors account for approximately 40% of all infertility. Conventional semen analysis focus on seminal physicochemical property and spermatozoa morphology. They yield no information concerning the functional competence of the spermatozoa(Petrunkina et al., 2007). Owning to the essential role of proteins in the reproductive process, comprehensive and systematic identification of proteome is critical to gain new insights into spermatogenesis and infertility. Recent advances in mass spectrometry have allowed the identification of hundreds to thousands of protein in spermatozoa(Oliva et al., 2008; Amaral et al., 2014; Codina et al., 2015). In major domestic mammalian species, global spermatozoa proteomic profiles have been described in rodents(Baker et al., 2008a; Baker et al., 2008b) and bovine(Peddinti et al., 2008). Meanwhile, lacking of new protein synthesis in spermatozoa supports the current view that the regulation of sperm maturation is controlled by exogenous proteins(O'Rand et al., 2011) (e.g., during epididymal transit). Among the seminal plasma proteins, The human seminal plasma has been comprehensively described (Pilch and Mann, 2006; Batruch et al., 2011; Milardi et al., 2012; Milardi et al., 2013; Sharma et al., 2013). In domestic animal species, some studies performing a systematic analysis on using high throughput proteomics have been performed(Kelly et al., 2006; Moura et al., 2007; Souza et al., 2012; Druart et al., 2013; Soleilhavoup et al., 2014). Buffalos (Bubalus bubalis) are adapted to hot–humid tropical climatic conditions, but have low reproductive efficiency. The low sperm motility maybe contributed to protein components variation of spermatozoa and seminal plasma. The composition of buffalo spermatozoa and buffalo seminal plasma (BSP) remains unknown. Proteomic study would be beneficial to the elucidation of the roles of sperm and BSP proteins in regulation of maturation, motility and fertilization. As such, the aim of the current study was to extensively characterize the differentially expressed protein of buffalo spermatozoa and seminal plasma using a comparative proteomics.
