The meeting held in Mineral Hall B was called to order at 5:00 p.m. by Chair Curt Youngs. Bob Godke moved and Matt Wheeler seconded a motion to approve the minutes of last years annual meeting. The motion carried unanimously. Mark Mirando, CSREES Representative, presented a short report. Mark discussed the USDA budget for the upcoming year. He indicated that there was an additional $20 million in Hatch funds for 2007 compared to 2006. This was due to the fact that all special grant funds were rolled into Hatch funds last year. In 2008, however, these special grant funds were removed from the budget. He also indicated that there was a $1.5 million increase in Smith Lever funds and funding for integrated projects within NRI increased from 22 to 26% this past year. Mark indicated that the USDA would be moving to electronic submission of research proposals for all programs and that fillable forms in portable document format (PDF) would potentially be available next year. In addition, he promoted two upcoming Grant Writing Workshops to be held in Salt Lake City, UT and Washington, D.C. Finally, Dr. Mirando indicated that more funds were budgeted for the NRI. Practically, this means that the Animal Reproduction program could fund one additional research proposal. A good discussion with the committee followed. The W-1171 Administrative Assistant, C. Y. Hu, provided his report to the committee. First, he apologized for being unable to attend the 2007 annual meeting in Kyoto, Japan. Next, he indicated that the Western states were really hurt by the reduction in special grants last year, estimating that Hawaii lost approximately $7 million. Funds went to CSREES but not necessarily to all the experiment stations, therefore only certain stations benefitted from these additional funds. In addition, C. Y. mentioned that Congress always passes appropriations in March after the end of the fiscal year on October 1. However, last year they just approved a continuing appropriation. He also suggested that it has been a tough 1½ to 2 years for experiment station directors. The Farm Bill has required lots of haggling by the directors, utilizing much of their time. Additionally, a great deal of debate ensued over agricultural subsidies. Currently, NIFA is in both the House and Senate versions of the Farm Bill. Further, he indicated that they lost IFAFS funding as well. C. Y. indicated that the budget picture for the upcoming year looks unfavorable. There has been $195 million allocated to the NRI program. Another $195 million is budgeted for Hatch funds. Of these Hatch funds, 25% has to be used for experiment stations in each state to support formula funds. As an additional note, C. Y. mentioned that in the future, many areas of USDA would be combined in an attempt to streamline and incorporate a hierarchy similar to NIH. In regard to the W-1171 committee, C. Y. pointed out that the committee had its mid-term review this past year. He reported that the review team was very happy with the performance of the committee. In addition, he indicated that a revised project for the W-1171 committee would be due by the 2009 annual meeting. He expects a reasonably good draft by the next annual meeting. He suggested that our accomplishments were relatively easy to document. However, he stressed the importance of documenting impacts of our research. It is important to focus on integrated, multistate linkages. Again, collaborations among institutions and impacts could not be stressed enough. Both C. Y. and Mark Mirando agreed that 3 to 5 good impact statements would be sufficient for the renewal proposal and that each impact statement should be no more than 2 sentences. C. Y. warned that the majority of impact statements simply reiterate the objectives or methods, suggesting that the committee avoid this pitfall. He also indicated that the impact statement should not include the impact will be& Suggested examples of terminology to include in impact statements were: 1) Increased conception rates, reproductive efficiency or birth rates. 2) Decreased production costs. 3) Improved animal welfare. 4) Increased global competitiveness. Both C. Y. and Mark Mirando indicated that impact statements should be general in nature. It is important to identify critical gaps in the knowledge base and suggest how these gaps will be filled. Brett White will become Chair of the committee for the 2008 calendar year. Because there were no nominations for secretary, both Peter and Char Farin volunteered to serve as Co-Secretaries for the 2008 calendar year. Peter and Char will assume duties of Committee Co-Chairs for the 2009 calendar year. The 2009 W-1171 annual meeting will be held in conjunction with the IETS meetings in San Diego, California (January 4-7). It was suggested that the committee try to meet around the end of the meeting but prior to the post-conference symposia. Brett White will contact Jennifer Gavel to arrange a room and time. To avoid time constraints, individual station reports were excluded in order to allocate additional time to discuss the objectives for the upcoming rewrite. At 5:55 pm, the committee began to discuss the objectives for the renewal proposal. Discussion of Objective 1 from our last proposal revolved around the idea of incorporating physiological genomics into a similar objective. It was noted that at least six members of the committee were performing this type of research. However, the committee agreed that this terminology might be too specific for an objective encompassing the research of so many scientists and thus chose to keep the language more general. Bob Godke moved and Char Farin seconded a motion that the first objective stand as is, Understand the biology and underlying mechanisms of gamete development, fertilization, and embryogenesis. Discussion of the second objective from our previous proposal ensued. Chairman Youngs suggested including genetically enhanced animals instead of genetically modified animals in this objective. Bob Godke moved to entitle the second objective, Refine methods for production of genetically enhanced animals to improve livestock production efficiency. The motion was seconded by Peter Farin and the committee passed the motion unanimously. Next, the committee focused on the rewrite. A recommendation was brought forward to divide the writing into specific sections. Erdogan Memili, Rebecca Krisher and Brett White volunteered to serve as overall coordinators for the sections of the rewrite. Two important components of the proposal identified were the critical reviews of the literature and the project methods. The committee agreed that members assisting with the writing concentrate on the impacts and linkages among research stations. The question was raised whether the committee needed to include year by year milestones. Our Administrative Assistant, C. Y. Hu, indicated that this format was not required. Finally, Chair Youngs asked that all committee members be responsible and timely in responding to information sent out via email regarding the renewal proposal. Charlie Rosenkrans moved and Rebecca Krisher seconded a motion to adjourn the business meeting. The motion carried unanimously, and the business meeting was adjourned at 6:30 p.m. The committee met at 8:30 a.m. on January 6, 2008 in the same room to discuss collaborative projects for the rewrite. Before discussions began, Chairman Youngs suggested that we have a good draft of the rewrite by September 1, 2008, taking advantage of time flexibility over the summer months. Secretary White would send out a reminder around May 1, 2008 encouraging everyone to complete their delegated parts of the proposal. Members were reminded that the success of the multistate project hinges on productive collaborations and that the viability of W-1171 is contingent upon joint research efforts (and not on individual station research efforts). The W-1171 members broke out into the two objectives that were agreed upon the previous day. The groups were asked to identify new possibilities for collaborative research efforts. Moderators of each group were to provide a summary of the ideas derived by each group to the Secretary, Brett White, so that he could compile the findings and send them out to the committee for further input. Following group discussions, the meeting was adjourned. Respectfully submitted, Brett White 2007 W-1171 Secretary

Accomplishments

We examined gene expression in oocytes of good and poor quality, identifying alterations in the transcriptome of oocytes matured in vitro compared to those matured in vivo that correlate to developmental competence. These results indicated that gene expression is altered in oocytes matured in vitro compared to those in vivo. Based on the functional annotations of genes differentially expressed, dysregulation of gene expression resulting in altered DNA methylation and an up regulation in cell death pathways are potential developmental mechanisms influenced by in vitro culture conditions that correlate to reduced embryonic developmental potential. Of particular interest the functional category of gene expression. This category includes genes involved in the regulation of gene expression, including those genes controlling histone modifications and chromatin structure. Our microarray results demonstrate that genes in this category are specifically associated with differences in oocyte quality. Developmental potential of oocytes derived from sows and gilts was determined after in vitro maturation, fertilization and culture. This data confirms that gilt derived oocytes matured and cultured in vitro have a similar ability to undergo nuclear maturation compared to sow derived oocytes. Gilt oocytes, however, display a decreased ability to undergo embryonic developmental, suggesting that gilt oocytes have not fulfilled all the required mechanisms for cytoplasmic maturation and normal embryonic development. Member scientists used computer assisted sperm analysis (CASA) to evaluate the effects of techniques routinely used for selection of motile sperm prior to IVF on sperm quality parameters, and the effects of PHE on sperm parameters of semen varying in quality. Results suggest that the method used for selection of motile sperm can influence parameters related to motility and sperm head morphology. The beneficial effects of PHE on sperm over time, particularly those of poor quality, were identified. The effects of tobacco smoke compounds on sex ratio were investigated for potential application to sex selection in livestock. Results suggest that these tobacco compounds reduce the male to female sex ratio of bovine embryos, confirming previous reports in humans. Other researchers acquired data suggesting that oocyte receptors can be used as an estimate of oocyte quality and that the interval prior to fertilization is sensitive to heat stress in the pig. Investigators have developed and validated a simple, objective method of quantifying lipids in bovine embryos. They also found that injecting inositol triphosphate at the time of ICSI of bovine oocytes resulted in improved cleavage rates, as well as a non-significant increase in blastocyst production. Validated a method to study how bovine oocytes modify mRNA during maturation, mostly by selective degradation of specific mRNAs. The assay is sensitive enough such that one can inject labeled constructs and recover them in a modifed form some hours later in sufficient quantities to make meaningful measurements. Found that mRNA for the gene, periattachment factor, increased dramatically in elongating ovine embryos, from non-detectable on day 11 to a peak on day 16, and subsequent decline to very low levels by day 30. This timing is very similar to what is seen in bovine embryos. Since mRNA for this molecule rises sharply during elongation and falls to nearly undetectable concentrations when elongation ceases, it likely has a very important function that we are trying to understand. This molecule could be key to understanding the high incidence of embryonic death that normally occurs at this stage. Compared differences in gene expression of embryos fertilized and developed in vivo from in vivo matured oocytes to those that are fertilized in vitro but cultured in vitro from in vivo matured oocytes and those that were fertilized and cultured in vitro from in vitro matured oocytes. Developed miniaturization technologies toward microfluidics and small mechanical systems, microelectromechanical systems (MEMS), creating a means for dynamic culture on a volumetric scale, reportedly more consistent with the needs of the embryo. We have shown that either chemical (cycloheximide) or electrical methods are adequate and efficient for the activation of embryonic structures reconstructed by the hand-made cloning technique. Identified two novel Lef1 isoforms expressed in bovine preimplantation embryos. Studies using siRNA knockdown are ongoing to determine the role of this transcription factor in blastocyst formation. Determined in vitro culture conditions supporting better development of porcine oocytes in vitro. Provided functional genomics blue prints (proteomics) of bovine oocytes and spermatozoa. We have determined an important role for GnRH during embryogenesis, having a receptor mediated effect on 1-cell embryos that occurs within the first 36 hours of embryo development. Established biotin effects on oocyte maturation in mice, identified genes that are up- or down-regulated in oocytes from biotin-deficient compared to biotin-normal mice, and examined intracellular signaling cascades and molecular mechanisms underlying biotin effects on oogenesis and subsequent development. Found that production of bovine embryos in vitro using a serum based system was associated with increased body weight, normal liver and kidney morphology, and increased concentrations of blood urea nitrogen of fetuses during late gestation. Identified that bovine Air ncRNA is expressed in cattle and determined expression of bovine Air ncRNA in fetal tissue at the post-implantation and peri-implantation stages but not in preimplantations stages of development. Found that method of embryo production altered expression of bovine Air ncRNA in fetal tissue at day 70 of gestation. Determined the status of a range of imprinted genes in swine. Annotated and compared several platforms for porcine gene expression profiling studies. Identified potential candidate mRNAs associated with FSH-induced initiation of GVBD in murine and bovine cumulus-oocyte complexes matured in vitro. Used short interfering RNA approaches to assess the functional roles of NR4a1 and Egr1 mRNAs during FSH-induced oocyte maturation in cattle. Determined that a spermicidal compound can be encapsulated in cyclodextrin without loss of spermicidal activity. Found that ejaculated equine spermatozoa contain measurable amounts of various mRNAs for genes associated with testicular spermatogenesis. Determined that sperm protein (SP)-22 was specifically localized in equine spermatozoa and that SP-22 expression was altered with season of collection. Provided new information regarding the developmental biology of the early bovine embryo. Evaluated the efficacy of the commercially available semen sexing kit; HeiferPlus". Although more research is necessary (as is usual with binary data), perhaps a more compelling observation is the potential that incubation alone of bovine semen prior to AI may sway the sex ratio in favor of the female in superovulating (but not single ovulating) cows. The chemical composition of estrous synchronization implants used in this research must be manipulated to allow ease of insertion and removal, but the protein release profiles (in vitro and in vivo) are encouraging. Ultimately, the variety of the FSH loaded into the implant (recombinant or pituitary derived, glycosylated or not) may determine the type of material used to construct the implant. Further research is necessary to determine the precise FSH (and perhaps LH) release profile to reliable stimulate follicular waves to produce multiple dominant follicles, fertilizable oocytes, and developmentally competent embryos. We studied the role of disintegrin-integrin dynamics in sperm-oocyte interactions. Investigated differential gene expression of somatic cell nuclear transfer embryos and placental tissue as compared to controls. Examined the effects of nicotine on bovine meiotic maturation in vitro and subsequent embryonic development. Since the mRNA and protein of the novel importin ± are extremely abundant in oocytes and early cleavage stage embryos, but barely detectable in morula and blastocyst stage embryos, we believe that this novel importin ± is a maternal effect gene that is essential for early embryogenesis. Compared gene expression in cloned and control pigs and calves. Examined the methylation patterns of the intergenic region of H19-IGF2 in cloned calves. Found that enhanced lactation potential of transgenic gilts (bovine alpha-lactalbumin) synergizes with suckling intensity to stimulate increased milk production during early lactation, as well as stimulating piglet growth. These animals provide a method to manipulate lactation persistency in swine. Preliminary results indicate absence of the transgene in control animals after co-habitation and post-mating with transgenic animals. This work provides a critical first step toward providing rigorous scientific data for risk assessment of transgenic livestock. Determined that the use of multi-factorial directed differentiation using high-speed robotic systems will enable the examination of large matrices of culture and differentiation conditions for stem cells. Furthermore, this approach enables analysis of gene expression and other cell characteristics related to differentiation and cell function from cells cultured under essentially unlimited conditions. Using the automated microscale system in large factorial experiments allows analysis of the basic mechanisms underlying stem cell development in vitro, and ultimately in vivo. Determined that Noggin, a cytokine, helps maintain expression of the pluripotency transcription factor Nanog during ICM explant culture. Identified functional genomics (transcriptomics) of bovine cloned embryos from IVF and several rounds of chromatin transfers. Established divergent survival rates for cryopreserved embryos from Chinese Meishan and white crossbred lines of swine. This difference in survival rate occurs within the first 24 hours following thawing. Determined the most efficient method for SCNT cloning in pigs. Unlike cattle and sheep, SCNT in pigs does not generate large offspring but instead increases the incidence of IUGR. Tested different methods for enhancing homologous recombination in somatic cells. Identified single nucleotide polymorphisms in the promoter regions of the prolactin and HSP-70 genes of cattle that are related to cattle fecundity. Boar libido was not detectably reduced by lowering endogenous estrogens in an attempt to increase sperm production.

Impacts

  1. 1. Elucidation of specific molecular mechanisms critical to oocyte competence will allow development of effective strategies to alter precise pathways critical to developmental potential of oocytes.
  2. 2. Application of the results of these studies should lead to refinement and improvement of procedures for in vitro production of embryos, and possibly AI pregnancy rates.
  3. 3. Understanding gene expression differences among embryos produced by various assisted biotechnology techniques has the potential to improve culture media and embryo production efficiency through in vitro production systems.
  4. 4. Development of efficient IVP systems using microscale technologies will enable the automation of such techniques for production of large numbers of embryos in vitro, accelerating genetic improvement and selection of superior livestock.
  5. 5. Identification of specific mRNAs regulating the resumption of meiosis in mammalian oocytes may provide novel opportunities for the development of gene-targeted contraceptive methods useful for the manipulation of reproductive cycles in livestock.
  6. 6. Research in bovine embryo physiology may provide insights into aberrant mechanisms that predispose the embryo to pregnancy loss due to abnormal development and/or implantation failure.
  7. 7. Swaying the sex ratio of offspring will assist livestock producers in reaching their genetic, financial, and reproductive goals.
  8. 8. Identification of mRNAs and proteins in spermatozoa that are known to be associated with the progression spermatogenesis may provide potential markers for predicting fertility.
  9. 9. Isolation of cytokines that extend expression of the pluripotency-related transcription factor, NANOG, will aid in derivation of embryonic stem cells, providing an invaluable tool for improved production traits, disease resistance and production of biopharmaceuticals via genetic engineering.
  10. 10. Isolation and differentiation of mesenchymal lineage stem cells in vitro, as well as transplantation into live animals with corresponding proper differentiation, will allow stem cell therapy for production parameters such as lactation and muscle growth in livestock.
