Also was measured the NGF concentration in the blood and seminal plasma by ELISA. Study 1 was performed at Federal University of Ceará, in Fortaleza-Ce. Semen samples were collected from 18 adult rabbits, using an artificial vagina. After collecting proceeded to the evaluation of semen quality parameters: total motility, individual progressive motility, sperm concentration, sperm morphology and functional tests: membrane integrity (HOST), acrosomal integrity and vitality. The seminal plasma was obtained by centrifugation of semen, and subjected to two-dimensional electrophoresis. Gels were stained with colloidal Coomassie, scanned and analyzed in PDQuest application. The individual spots were excised from the gels, digested with trypsin, and submitted to mass spectrometry (ESI-QUAD-TOF) to identification. The results were subjected to statistical analysis to verify the existence of associations between the presence and / or intensity of the spots present in the protein maps of seminal plasma with the semen quality parameters. The associations between the parameters of ejaculated sperm and the expression of seminal plasma proteins of rabbits were estimated by multiple regression models using the REG procedure of SAS statistical application (v.9.0, 2002) with STEPWISE selection. 232 ± 69.5 spots/gel were detected with 34 spots consistently present in all gels. These 34 spots corresponded to 15% of the total number of spots, representing 32% of the optical intensity of all the spots. Mass spectrometry identified approximately 95% of the detected spots (identified: 220 spots; analyzed: 232 spots), which corresponded to 87 different proteins. The most abundant proteins were the annexins, zeta-globin, lipocalin, FAM 115 protein and a serpins cluster. Other proteins also have been identified, such as transferrin, heat shock protein, glutathione transferase and others. The NGF (protein nerve growth factor) presence also has been identified which has been reported in other species such as ovulation induction factor. This 87 proteins identified in seminal plasma of rabbits participate mainly of biological processes associated with cellular processes (65.25%), regulation (64.25%) and response to stimuli (22.9%). Significant associations were observed between the proteins identified in seminal plasma of rabbits with sperm evaluated parameters such as individual progressive motility, sperm viability, cells with morphology and functional membranes have been associated with specific proteins. Associations were observed for several proteins with the same sperm parameter. According to literature, this is first report about the proteome of seminal plasma of rabbits and its role on the seminal parameters. Knowledge of these proteins contributes to a better understanding of the regulatory mechanisms of seminal plasma on sperm function in rabbits. Study 2 was conducted at Università Degli Studi di Perugia in the city of Perugia-Pe, Italy. It was evaluated the expression of NGF protein that was previously identified during study 1. The immunoreactivity and gene expression of NGF and cognate receptors were detected in testis, prostate and seminal vesicle. The highest levels of NGF and NTRK1 transcripts were found in prostate, while intermediate expressions were found in testis. NGFR transcripts were expressed at the same level on both the testis and prostate, and were more abundant than in seminal vesicles. The widespread distribution of NGF in all glandular cells of the prostate, coupled with its high abundance of mRNA on confirm that the prostate is a major source of this neurotrophin in rabbits. In conclusion, the present data suggest that NGF is involved in developmental system and spermatogenesis of testis rabbits and that NGF can act as a potential factor for induction of ovulation, being abundantly present in seminal plasma. / Os objetivos deste estudo foram (i) mapear e identificar as proteínas do plasma seminal de coelhos da raça Nova Zelândia Branca, utilizando as técnicas de eletroforese bidimensional associada à espectrometria de massa e estimar associações entre essas proteínas com os parâmetros espermáticos e (ii) caracterizar a expressão do fator de crescimento nervoso, poliptido beta ( -NGF), e os seus receptores cognatos neurotróficos da tirosina-quinase de tipo 1 (NTRK1) e receptor fator de crescimento nervoso (NGFR) nas gônadas e glândulas sexuais de coelhos da raça Nova Zelândia Branca, bem como as concentrações de NGF no plasma seminal de animais sexualmente maduros, utilizando as técnicas de RT - PCR e imunohistoquímica. Também foi dosada a concentração da NGF no sangue e no plasma seminal através da técnica de ELISA. O estudo 1 foi realizado na Universidade Federal do Ceará, na cidade de Fortaleza-Ce. Foram coletados amostras de sêmen de 18 coelhos adultos, utilizando- se uma vagina artificial. Após a coleta procedeu-se a avaliação dos parâmetros qualidade seminal: motilidade, vigor, concentração espermática, morfologia espermática e os testes funcionais: integridade de membrana, integridade acrossomal e vitalidade. O plasma seminal foi obtido pela centrifugação do sêmen, e submetido à eletroforese bidimensional. Os géis foram corados com Coomassie coloidal, digitalizados e analisados no aplicativo PDQuest. Os spots foram cortados individualmente dos géis, digeridos com tripsina, e submetidos à identificação por espectrometria de massa (ESI- QUAD-TOF). Os resultados obtidos foram submetidos a avaliação estatística para verificar a existência de associações entre entre a presença e/ou intensidade dos spots presentes nos mapas protéicos do plasma seminal com os parâmetros de qualidade seminal. As associações entre os parâmetros dos espermatozoides ejaculados e a expressão das proteínas do plasma seminal dos coelhos foram estimadas por modelos de regressão múltipla usando o procedimento REG do aplicativo estatístico SAS (v.9.0, 2002) com a seleção STEPWISE. Foram detectados 232 ± 69,5 spots protéicos por gel, com 34 spots presentes consistentemente em todos os géis. Esses 34 spots corresponderam a 15 % do total do número de spots, representando 32 % da intensidade óptica de todos os spots. A espectometria de massa identicou aproximadamente 95% dos spots detectados (220 spots de um total de 232), que corresponderam a 87 proteínas diferentes. As proteínas mais abundantes foram as anexinas, zeta-globina, lipocalinas, proteina FAM 115 e um grupamento de serpinas. Outras proteínas também foram identificadas, tais como: transferrina, heat shock protein, glutationa transferase, entre outras. Também foi identificada apresença da proteína fator de crescimento nervoso (NGF) que tem sido relatada em outras espécies como fator de indução à ovulação. As 87 proteínas identificadas no plasma seminal de coelhos participam principalmente dos processos biológicos associados a processos celulares (65,25 %), regulação (64,25 %) e resposta a estímulos (22,9 %). Foram observadas associações significativas entre as proteínas identificadas no plasma seminal de coelhos com os parâmetros espermáticos avaliados,tais como vigor, número de células viáveis, morfologia espermática e células com membranas funcionais foram associados com proteínas específicas. Foram observadas associações de várias proteínas com um mesmo parâmetro espermático. De acordo com a literatura, este representa o primeiro relato sobre o proteoma do plasma seminal de coelhos e seu papel sobre os parâmetros seminais. O conhecimento dessas proteínas contribuirá para uma melhor compreensão dos mecanismos de regulação do plasma seminal sobre a função espermática em coelhos. O estudo 2 foi conduzido na Università Degli Studi di Perugia, na cidade de Perugia-Pe, Itália. Foi avaliada a expressão da proteína NGF que foi previamente identificada no estudo 1. A imunorreatividade e a expressão gênica da NGF e os seus receptores cognatos foram detectados nos testículos, próstata e vesícula seminal. Os níveis mais elevados de NGF e NTRK1 transcritos foram encontrados na próstata, enquanto expressões intermediárias foram encontradas no testículo. NGFR transcritos foram expressos nos mesmos níveis em ambos os testículos e da próstata e eram mais abundantes do que nas vesículas seminais. A distribuição generalizada de NGF em todas as células glandulares da próstata, juntamente com a sua abundância de RNAm relativo, confirmam que a próstata é das principais fontes desta neurotrofina em coelhos. Em conclusão, os presentes dados sugerem que o sistema NGF está envolvido no desenvolvimento testicular e espermatogênese de coelhos e que o NGF pode atuar como um potencial fator de indução à ovulação, sendo abundantemente presentes no plasma seminal.

Los objetivos generales de esta tesis fueron desarrollar nuevos diluyentes de inseminación artificial (IA) suplementados con un análogo de GnRH y caracterizar el proteoma del semen de conejo. En el capítulo I, se evaluó la inclusión de un cóctel de inhibidores de proteasas en el diluyente de inseminación (DI) para evitar parte de la actividad proteasa del plasma seminal de conejo. La calidad seminal y la fertilidad no se vieron afectadas por el cóctel. Sin embargo, la prolificidad fue significativamente menor en el grupo experimental en comparación con los grupos de control positivo y negativo (8,2±0,22 vs. 9,3±0,23 y 9,2±0,26 gazapos por parto, respectivamente). De este capítulo, se puede concluir que la adición de una amplia variedad de inhibidores de proteasas en el diluyente de semen de conejo afecta negativamente la tasa de prolificidad y que en el futuro sería aconsejable probar inhibidores específicos de aminopeptidasas (AMIs). En el capítulo II, suplementamos el DI con AMIs (bestatina y EDTA), y estudiamos su efecto sobre la calidad seminal y el rendimiento reproductivo. La inclusión de AMIs no afectó la calidad seminal, ni la fertilidad (85,3 vs. 88,6%), ni la prolificidad (10,12 vs. 10,51 gazapos por parto) en comparación con el grupo control. Por lo tanto, concluimos que los AMIs se pueden utilizar en los DIs de conejo para inhibir parte de la actividad aminopeptidasa del plasma seminal (PS). En el capítulo III, probamos nuevos DIs de conejo que contenían AMIs con o sin nanopartículas de quitosano (CS)-sulfato de dextrano (DS) que atrapan el análogo de GnRH. Se estudiaron los siguientes diluyentes: C4 (4 µg de buserelina/coneja en medio control (MC): tris-ácido cítrico-glucosa suplementado con AMIs), C5 (5 µg de buserelina/coneja en MC), Q4 (4 µg de buserelina/coneja en nanopartículas CS-DS en MC) y grupo Q5 (5 µg de buserelina/coneja en nanopartículas CS-DS en MC). La fertilidad fue significativamente menor en el grupo C4 en comparación con los grupos C5, Q5 y Q4 (0,7 frente a 0,85, 0,85 y 0,82, respectivamente). Por el contrario, la prolificidad fue similar en los cuatro grupos experimentales. Por lo tanto, las nanopartículas de CS-DS como transportador de acetato de buserelina permiten reducir la concentración de la hormona en diluyentes con AMIs sin afectar la fertilidad ni la prolificidad. Por ello, la nanoencapsulación parece ser un sistema prometedor para proteger el análogo de GnRH en los diluyentes de IA de conejos. Por otro lado, el objetivo de los últimos tres capítulos fue caracterizar las proteínas del semen de conejo. En los capítulos IV y V, se estudiaron las proteínas del PS de conejo. Las muestras de semen se recuperaron utilizando 6 machos de cada línea genética (A y R) y seleccionando una muestra heteroespérmica del comienzo, del medio y del final de cada estación y de cada línea (24 muestras en total). En el capítulo IV, utilizamos la técnica de electroforesis en gel de poliacrilamida 1D. Siete bandas proteicas fueron significativamente diferentes entre las líneas genéticas y tres bandas entre las estaciones. En el capítulo V, se sometió el PS a nano LC-MS/MS y se identificaron y cuantificaron 402 proteínas. 23 proteínas se expresaron diferencialmente entre genotipos. Con respecto al efecto de la estación en el proteoma del PS de conejo, los resultados mostraron que no hubo un patrón claro de variación de proteína a lo largo del año. En el capítulo VI, se caracterizaron las proteínas del espermatozoide de conejo. Se recuperaron 6 muestras espermáticas utilizando 5 machos de cada genotipo y se sometieron a nano LC-MS/MS, identificándose y cuantificándose 487 proteínas. 40 proteínas se expresaron diferencialmente entre genotipos. En conclusión, los resultados de los tres últimos capítulos evidencian que el genotipo está relacionado con una abundancia específica de proteínas del PS y del espermatozoide. Finalmente, se creó la / The general objectives of this thesis were to develop new artificial insemination (AI) extenders supplemented with a GnRH analogue and to characterise the proteomic profile of rabbit semen. In chapter I, the inclusion of a protease inhibitors cocktail in the insemination extender (IE) to avoid part of the rabbit seminal plasma protease activity was evaluated. Seminal quality and fertility rate were not affected by the cocktail, having similar values between experimental and control groups. However, prolificacy rate was significantly lower in experimental group compared to positive and negative control groups (8.2 ±0.22 vs. 9.3 ±0.23 and 9.2 ±0.26 total born per litter, respectively). From this chapter, it may be concluded that the addition of a wide variety of protease inhibitors in the rabbit semen extender negatively affects prolificacy rate and it in the future it would be advisable to test specific aminopeptidase inhibitors (AMIs). Therefore, in chapter II, we supplemented the IE with AMIs (bestatin and EDTA), and we studied their effect on rabbit seminal quality and reproductive performance. Seminal quality was not affected by AMIs. Regarding reproductive performance, the inclusion of AMIs, did not affect fertility (85.3 vs. 88.6%), nor the prolificacy rate (10.12 vs. 10.51 kits per delivery) in comparison with control group. Thus, we concluded that AMIs can be used in rabbit IEs to inhibit part of the seminal plasma aminopeptidase activity. In chapter III, we test new rabbit IEs containing AMIs with or without chitosan (CS)-dextran sulfate (DS) nanoparticles entrapping the GnRH analogue. The following experimental extenders were studied: C4 (4 µg buserelin/doe in control medium (CM): Tris-citric acid-glucose supplemented with AMIs), C5 (5 µg of buserelin/doe in CM), Q4 (4 µg of buserelin/doe into CS-DS nanoparticles in CM) and Q5 group (5 µg of busereline/doe into CS-DS nanoparticles in CM). Results showed that fertility was significantly lower in C4 group compared to C5, Q5 and Q4 groups (0.7 vs. 0.85, 0.85 and 0.82, respectively). On the contrary, prolificacy was similar in the four experimental groups studied. Thus, CS-DS nanoparticles as carrier for buserelin acetate allow reducing the hormone's concentration in extenders supplemented with AMIs without affecting the fertility and prolificacy of rabbit females. Therefore, nanoencapsulation seems to be a promising system to protect the GnRH analogue in rabbit AI extenders. On the other hand, the aim of the last three chapters was to characterize rabbit semen proteins. In chapters IV and V, rabbit seminal plasma (SP) proteins were studied. Semen samples were recovered using 6 males from each genetic line (A and R). For each genotype, one pooled sample at the beginning, middle and end of each season was selected to develop the experiment (24 pools in total). In chapter IV, we used a 1D polyacrylamide gel electrophoresis approach. Seven protein bands were significantly different between genetic lines and three protein bands were significantly different between seasons. In chapter V, SP was subjected nano LC-MS/MS and 402 proteins were identified and quantified. Twenty-three proteins were differentially expressed between genotypes. Regarding the effect of season on rabbit SP proteome, results showed that there was no clear pattern of protein variation throughout the year. The results obtained in both chapters evidence that genotype is related to a specific abundance of SP proteins. In chapter VI, rabbit sperm proteins were characterised. Six samples were recovered during two months using 5 males from each genotype. Sperm proteins were subjected to nano LC-MS/MS and 487 proteins were identified and quantified. Forty proteins were differentially expressed between genotypes. In conclusion, rabbit sperm proteins showed that genotype has also a huge impact on their abundance. Finally, with these data, the first publicly accessible database of rabbit semen proteome was c / Els objectius generals d'aquesta tesi van ser desenvolupar nous diluents d'inseminació artificial (IA) suplementats amb un anàleg de GnRH i caracteritzar el proteoma del semen de conill. En el capítol I, es va avaluar la inclusió d'un còctel d'inhibidors de proteases en el diluent d'inseminació (DI) per evitar part de l'activitat proteasa del plasma seminal de conill. La qualitat seminal i la fertilitat no es van veure afectades pel còctel. No obstant això, la prolificitat va ser significativament menor en el grup experimental en comparació amb els grups de control positiu i negatiu (8,2 ± 0,22 vs. 9,3 ± 0,23 i 9,2 ± 0,26 catxaps per part, respectivament). D'aquest capítol, es pot concloure que l'addició d'una àmplia varietat d'inhibidors de proteases en el diluent de semen de conill afecta negativament la taxa de prolificitat i que en el futur seria aconsellable provar inhibidors específics de aminopeptidasas (AMIS). En el capítol II, suplementàrem el DI amb AMIs (bestatina i EDTA), i vam estudiar el seu efecte sobre la qualitat seminal i el rendiment reproductiu. La inclusió de AMIs no va afectar la qualitat seminal, ni la fertilitat (85,3 vs. 88,6%), ni la prolificitat (10,12 vs. 10,51 catxaps per part) en comparació amb el grup control. Per tant, concloem que els AMIs es poden utilitzar en els DIs de conill per inhibir part de l'activitat aminopeptidasa del plasma seminal (PS). En el capítol III, vam provar nous DIs de conill que contenien AMIs amb o sense nanopartícules de quitosà (CS)-sulfat de dextrà (DS) que atrapen l'anàleg de GnRH. Es van estudiar els següents diluents: C4 (4 µg de buserelina/conilla en medi control (MC): tris-àcid cítric-glucosa suplementat amb AMIs), C5 (5 µg de buserelina/conilla en MC), Q4 (4 µg de buserelina/conilla en nanopartícules CS-DS en MC) i grup Q5 (5 µg de buserelina/conilla en nanopartícules CS-DS en MC). La fertilitat va ser significativament menor en el grup C4 en comparació amb els grups C5, Q5 i Q4 (0,7 enfront de 0,85, 0,85 i 0,82, respectivament). Per contra, la prolificitat va ser similar en els quatre grups experimentals. Per tant, les nanopartícules de CS-DS com a transportador d'acetat de buserelina permeten reduir la concentració de l'hormona en diluents amb AMIs sense afectar la fertilitat ni la prolificitat. Per això, la nanoencapsulació sembla ser un sistema prometedor per protegir l'anàleg de GnRH en els diluents d'IA de conills. D'altra banda, l'objectiu dels últims tres capítols va ser caracteritzar les proteïnes del semen de conill. En els capítols IV i V, es van estudiar les proteïnes del PS de conill. Les mostres de semen es van recuperar utilitzant 6 mascles de cada línia genètica (A i R) i seleccionant una mostra heteroespérmica del començament, del mitjan i del final de cada estació i de cada línia (24 mostres en total). En el capítol IV, utilitzàrem la tècnica d'electroforesi en gel de poliacrilamida 1D. Set bandes proteiques van ser significativament diferents entre les línies genètiques i tres bandes entre les estacions. En el capítol V, es va sotmetre el PS a nano LC-MS / MS i es van identificar i quantificar 402 proteïnes. 23 proteïnes es van expressar diferencialment entre genotips. Pel que fa a l'efecte de l'estació en el proteoma del PS de conill, els resultats van mostrar que no hi havia un patró clar de variació proteica al llarg de l'any. En el capítol VI, es van caracteritzar les proteïnes de l'espermatozoide de conill. Es van recuperar 6 mostres espermàtiques utilitzant 5 mascles de cada genotip i es van sotmetre a nano LC-MS / MS, identificant i quantificant 487 proteïnes. 40 proteïnes es van expressar diferencialment entre genotips. En conclusió, els resultats dels tres últims capítols evidencien que el genotip està relacionat amb una abundància específica de proteïnes del PS i de l'espermatozoide.

The purpose of this study was to determine the effects of PAF treatment of rabbit spermatozoa on in vitro fertilization and subsequent blastocyst formation. Rabbit spermatozoa were exposed to PAF (10-7 M ), lyso-PAF (10-7 M ), or HIS (385 mOsm/kg) for 15 min prior to insemination of ovulated oocytes. Fertilized oocytes were cultured to the hatched blastocyst stage.

A cDNA clone encoding the entire amino acid sequence of rabbit brown adipose tissue uncoupling protein has been isolated and sequenced. The coding region of this cDNA is 80.6% identical to that of the rat uncoupling protein cDNA. In contrast to rat uncoupling protein for which there are two mRNAs of 1500 and 2000 nucleotides there is only one rabbit uncoupling protein mRNA of 2000 nucleotides. Whereas the rat cDNA hybridizes more strongly to the shorter rat uncoupling protein mRNA the rabbit cDNA hybridizes more strongly to the longer rat uncoupling protein mRNA. Primer extension and Northern blot analysis were performed to try to account for the difference of 430 ± 75 nucleotides between the two rat uncoupling protein mRNAs. Northern blot analysis indicated the presence of 355 more nucleotides in the 3'-untranslated region of the 2000 nucleotide long rat uncoupling protein mRNA than in the 1500 nucleotide long rat uncoupling protein mRNA. The two rat uncoupling protein mRNAs could therefore arise by differential processing. Primer extension revealed that the two rat uncoupling protein mRNAs have a 5'-untranslated region of approximately 186 nucleotides. The deduced amino acid sequence of rabbit UCP is 86% identical with both the rat and hamster proteins. Several regions are conserved in all three uncoupling proteins. The two longest regions of conservation are residues 52 to 69 and 82 to 100 of the mature proteins and correspond to two of several basic regions of the protein that have been suggested as possible targeting sequences. These conserved regions fall within amino acids 52 to 104 of the mature rat protein, which has been shown by others to target a passenger protein to mitochondria. Helical wheel diagrams that correspond to residues 52 to 68 and residues 72 to 92 reveal possible amphiphilic α-helical formations that may be involved in targeting. Regions corresponding to those conserved in the three UCPs are also conserved in three mammalian ADP/ATP carriers and may indicate a common role for these regions, perhaps including targeting. There is almost complete conservation of lysine, arginine, and cysteine residues that are thought to be involved in nucleotide binding and proton transport in the three UCPs. There is a threonine to alanine change at the carboxyl-terminus of the rabbit protein compared to the rat protein. This amino acid difference may explain the differential reactivities of rabbit and rat UCP with an antibody preparation against rat UCP. / Thesis / Master of Science (MSc)
