Administrative Information 1. In conducting this project, I agree to have my laboratory and all animals assigned to this protocol available for examination by IACUC members or Department of Comparative Medicine personnel at all times during the project. I understand that according to the regulations under which the IACUC is authorized, any time any animal is deemed to be in unacceptable distress or is receiving inhumane treatment, in the professional opinion of the attending veterinarian, the animal may be subjected to immediate euthanasia and/or the procedure immediately halted. The IACUC will be informed of any action taken. The Director of University Biological Resources may suspend a protocol, for cause, until the IACUC has reviewed the incidents leading to the suspension. If the animals assigned to this protocol are supported by a grant or contract, I further certify that the procedures described in this protocol agree with the procedures described in the grant or contract application. I agree to provide the IACUC with one copy of my grant or contract proposal to allow verification that the description of the animal use portion of the grant or contract agrees with the protocol. I understand that changes in animal use procedures during the grant or contract period must be described on the annual monitoring/review form. I understand that IACUC approval of this protocol does not guarantee availability of resources or services from the Department of Comparative Medicine. I certify the information provided herein is correct. I agree to accept responsibility for this project in accordance with all federal, state and local laws and regulations, NIH/ILAR guidelines, PHS Animal Welfare Assurance, and institutional policies and procedures. I certify I have read and agree to the above: I agree I disagree Objectives Please describe your objectives (255 characters MAX) The objective is to breed mice that lack expression of CCTalpha, the rate-limiting enzyme in phosphatidylcholine synthesis, specifically in B cells. These mice will be used to study phosphatidylcholine production in B cells. Rationale Please describe your rationale for pursing the following protocol procedures (500 character MAX) B cells produce antibodies that protect the body against infection. However, B cell cancers and antibody-mediated autoimmune diseases are major health problems. In activated B cells, there is a large increase in the synthesis of membrane lipids such as phosphatidylcholine. Therefore, we plan to further investigate the mechanisms that regulate lipid biosynthesis in activated B cells and explore their potential roles in determining the function and/or fate of activated B cells. Confidential- USA Internal Use Only xxxxxxxxxxxxxx Page 2 of 11 Description Please provide a general description of the following procedures. This protocol concerns the breeding of mice to generate pups in which the CCTalpha gene is conditionally deleted in B cells. The protocol is composed of 2 parts. In Part 1, the CD19-Cre model will be used to generate mice in which progenitor B cells undergo deletion of the CCTalpha gene at a very early step in development. In this case, the B cells "grow up" as CCTalphadeficient cells. In Part 2, the Cgamma1-Cre model will be used to generate mice in which mature B cells undergo deletion of the CCTalpha gene only after activation. Part 1: CD19-Cre mediated deletion of CCTalpha in progenitor B cells Expression of the CD19 gene begins at a very early step in B lymphocyte development in the bone marrow. Therefore, in the CD19-Cre model, floxed genes are deleted in progenitor B cells in the bone marrow. In our previous breeding protocol for these mice (#09003), we developed CCTalpha flox/flox; CD19 Cre/wt mice. These mice will be maintained as breeder pairs, and their litters will yield the pups needed for experimental purposes (experimental protocol #09031). We expect approximately 8 pups/month from each breeder pair, usually consisting of 4 CCTalpha flox/flox; CD19 Cre/wt pups (B cells lack CCTalpha), 2 CCTalpha flox/flox; CD19 wt/wt pups (B cells express CCTalpha), and 2 CCTalpha flox/flox; CD19 Cre/Cre (B cells lack both CCTalpha and CD19, not useful experimentally, these pups will be euthanized by CO2 euthanasia followed by cervical dislocation). However, this distribution can vary. Pups will be genotyped by PCR analysis of genomic DNA isolated from tail clippings. Tails will be clipped before 21 days of age, so anesthesia will not be required. Tail clipping will be done using sterile instruments on each animal. A 1 cm tail snip will be obtained and the pups will be monitored for excessive bleeding. A hole punch will be used to mark the pups' ears for identification. Tail clipping and ear punching will be performed by trained DCM personnel according to standard operating procedures. Part 2: Cgamma1-Cre mediated deletion of CCTalpha in activated B cells The Cgamma1 promoter becomes transcriptionally active only in activated B cells that have initiated isotype switching. Therefore, in the Cgamma1-Cre model, floxed genes are deleted only in mature B cells that have been activated. In our previous breeding protocol for these mice (#09003), we developed CCTalpha flox/flox; Cgamma1 Cre/wt mice. These mice will be maintained as breeder pairs, and their litters will yield the pups needed for experimental purposes (experimental protocol #11027). We expect approximately 8 pups/month from these breeder pairs, usually consisting of 4 CCTalpha flox/flox; Cgamma1 Cre/wt pups (activated B cells lack CCTalpha), 2 CCTalpha flox/flox; Cgamma1 Cre/Cre (activated B cells lack CCTalpha) and 2 CCTalpha flox/flox; Cgamma1 wt/wt pups (activated B cells express CCTalpha). However, this distribution can vary. Genotyping, tail clipping and ear punching will be done as described in Part 1 above. Breeder Replacement We will replace breeder pairs every 6 months. Retired breeders will be euthanized by CO2 euthanasia followed by cervical dislocation. Based on the previous 3 years of experience with these mouse models, we expect these mice to be healthy and to thrive under normal conditions. Thus, we do not expect health problems to arise in these animals. However, if at any time prior to the 6 month retirement, a breeder animal appears distressed as evidenced by loss of appetite, weight loss or lethargy, we will euthanize the animal by CO2 euthanasia followed by cervical dislocation. To replace retired breeders, we will use CCTalpha flox/flox; CD19 Cre/wt mice and CCTalpha flox/flox; Cgamma1 Cre/wt mice that have been set aside for this purpose from previous litters. 2. Describe the methods used to determine the number of animals needed for this project. List statistical tests or other methods used to determine these numbers. To maintain the colonies and generate the pups needed for experimental purposes, we anticipate needing 4 CCTalpha flox/flox CD19 Cre/wt breeder pairs (Part 1) and 4 CCTalpha flox/flox; Cgamma1 Cre/wt breeder pairs (Part 2) at a time. This will total 8 breeder pairs/year for Part 1 and 8 breeder pairs/year for Part 2. Assuming that a 30% failure rate is possible, we would like to plan for 11 breeder pairs/year for each Part (11 breeder pairs/yr x 3 yrs = 33 pairs x 2 parts = 66 pairs). Therefore, for this 3 year protocol, we request a total of up to 66 breeder pairs (132 mice). Confidential- USA Internal Use Only xxxxxxxxxxxxxx Page 3 of 11 Alternative Methodologies 3. Describe what alternatives to the use of animals were considered (e.g., computer modeling, tissue/cell culture, etc.) and explain why they cannot be used in place of this animal use protocol. Our goal is to further investigate the roles CCTalpha and phosphatidylcholine synthesis in the development and function of B cells in vivo. Therefore, mice with B cells that either express or lack CCTalpha are required. The complex processes that regulate B cell development, activation and fate are only partly understood and cannot be fully modeled using cell lines in vitro and/or computer modeling at this time. 4. State why a lower order would not be used in this study. Ex. mice instead of swine. The mouse remains the lowest order species appropriate for studies of immune cell development and function. 5. Describe considerations given to the use of alternatives to painful procedures which will be performed on the animal(s) in this project. If such alternative procedures cannot be used, provide justification for the use of painful procedures. There are no painful procedures in this breeding protocol. Non-Duplication of Research 6.
