Regulation of C. elegans

Ultimately I am interested in how biologic changes during aging are in part responsible for Geriatric syndromes, such as delirium and frailty, and influence the unique responses of Geriatric patients to illnesses and medications.

The orphan nuclear hormone receptor DAF-12 in C. elegans plays important roles in the determination of worm lifespan through the integration of both germline and daf-2 signaling. Additionally, daf-12 appears to act independently to alter longevity in response to changes in activity of the cytochrome P450 gene daf-9. While daf-9 mutants are long-lived compared to wild-type worms, the daf-9 mutation also results in essentially permanent dauer arrest and adult sterility resulting in the inability to maintain a homozygous daf-9 stock. This limits the opportunity to obtain sufficient homozygous adults to easily perform further analysis, such as microarray. To address this technical limitation, I explored the use of daf-c and daf-d daf-12 alleles as a means to study daf-12 signaling. These alleles were previously identified due their effects on dauer formation which is an alternate larval stage that worms enter under unfavorable environmental conditions, such as crowding, starvation, or elevated temperature. The designations daf-c and daf-d relate to whether the worm either enters dauer formation constitutively despite favorable conditions, daf-c, or is unable to enter dauer formation under any condition, daf-d. These mutants are viable as homozygotes and are significantly easier to maintain than daf-9 mutants.


I hypothesized that these daf-12 alleles could have opposing effects on lifespan. Indeed I found that these mutants have the predicted effects on adult longevity, with a 38% increase in lifespan between the alleles, and also have opposing effects on resistance to both oxidative and thermal stress. Importantly characterization of the daf-d mutant revealed that this mutation resulted in accelerated aging in young adulthood. I was able to exploit these daf-12 alleles to perform microarray analysis of gene expression differences and identify differentially expressed genes. This experiment is important as it provided the first look at the effects of daf-12 signaling on gene expression in the adult and contributes to the identification of genes that alter lifespan when activated or repressed. Comparison of the expression profiles with the profiles associated with dauer formation and long-lived daf-2 mutants revealed that while the profiles are largely different, there is significant overlap among the genes down-regulated, but not up-regulated, in all profiles. My results point to daf-12 signaling modulating aging and stress responses through the repression of gene expression. My conclusion is supported by the recent report of a co-repressor, DIN-1, that binds to DAF-12 and is required for the increased lifespan seen in daf-9 mutants. Experiments using RNAi have indeed demonstrated that the repressed genes have effects on worm longevity.

Cyclin-Dependent Kinase Function in Murine Tumor Models:

The goal of the proposed research is to understand the function of cyclin-dependent kinases (Cdks) in developing tumors. Cdks are a conserved family of serine/threonine kinases that serve a central role in regulating the eukaryotic cell cycle. There are at least nine members of the Cdk family, though only Cdk1 and Cdk2 are felt to be essential for cell cycle progression in all mammalian cells. Cdk activity is regulated both by interaction with regulatory subunits and through phosphorylation events. Cdk activation requires binding to a cyclin subunit. Cyclin concentrations oscillate during the mammalian cell cycle and each Cdk can interact with only a subset of different cyclins. Cdks are activated in a cell-cycle-specific manner and regulate a precisely ordered transition to the next phase of the cell cycle. The essential role of Cdks in cell cycle progression makes them a target of great interest for the development of specific Cdk inhibitors as anti-cancer agents.

Tumor cells develop a deregulated cell cycle which may render their growth especially sensitive to Cdk inhibition. This raises the possibility that selective Cdk inhibition may be possible in an organism such that tumor cells are predominantly killed. Currently no murine model exists to validate the role of specific Cdk inhibition in developing tumors. Analysis of individual Cdk functions in vivo requires a highly specific, potent and reversible inhibitor. No such inhibitor exists which can distinguish between the highly related but functionally distinct Cdk1 and Cdk2 molecules. I am using a recently developed chemical-genetic approach to generate mutant forms of Cdks that can be selectively inhibited in vivo by a soluble small molecule inhibitor. This approach will allow the analysis of Cdk function in developing tumors and will help validate whether selective Cdk inhibition can provide anti-cancer therapy. Analysis of these tumor models may also reveal new genes that regulate Cdk function in vivo and may serve as targets for new cancer diagnostic and therapeutic agents. Christopher Haqq, M.D., Ph.D.

Role of CD45 in a Mouse Model of Autoimmunity and Lymphoproliferation

CD45, a receptor-like protein tyrosine phosphatase (RPTP), is required for antigen receptor-mediated signaling on T and B cells by its ability to dephosphorylate the carboxy-terminal negative regulatory site of tyrosine phosphorylation in Src kinase. Previous studies from our lab, suggested that CD45 catalytic function is negatively regulated by dimerization of the CD45 cytoplasmic domain. The crystal structure of the membrane-proximal catalytic domain and the juxtamembrane domain of a related RPTP, RPTPa, suggested the presence of a wedge-like structure that could block the catalytic site of a partner phosphatase domain during dimerization. Modeling studies of CD45, based on that of RPTPa, and found that the CD45 model conformed well with the structure of RPTPa. Mutating a residue at the tip of the putative wedge in CD45 abolished the inhibitory effects of dimerization of a chimeric receptor in a transformed T cell line model (3). These results suggest that dimerization of CD45 inhibits its function via a wedge-like structure in its juxtamembrane domain.

Mutation of the homologous residue glutamic acid to arginine (E613R) in the murine CD45 gene by homologous recombination verified the physiologic role of this model. The lymphoid lineages of the resultant mice develop normally. However, at approximately 12-16 weeks of age, the homozygous mutant mice develop a lymphoproliferative and an autoimmunity syndrome typical of that seen in human lupus including anti-nuclear antibodies, anti-double stranded DNA antibodies and diffuse proliferative glomerulonephritis. These observations suggest that dimerization of CD45 plays a critical role in negatively regulating its function in vivo. This is the first in vivo evidence for such negative regulation by dimerization for any RPTP.

The goal of the current research is to define the molecular and cellular basis for the breakdown in tolerance and the development of autoimmunity in CD45 E613R mice. Current studies are focused on 1) defining the cell lineages responsible for and required for the disease, 2) defining the role of antigen in the development of autoimmunity in the CD45 E613R mutant mice; and 3) defining the molecular basis for the effects of the CD45 wedge mutant

Bcl-XL expression or ARF deficiency abrogates Myc-induced islet involution and promotes pancreatic b-cell hyperplasia

The c-Myc oncoprotein is a transcription factor of the basic helix-loop-helix class encoded by the c-myc proto-oncogene that is frequently deregulated and/or over-expressed in human cancers. Although the best documented function of c-Myc is its ability to induce cell proliferation it is also a potent promoter of apoptosis, a property that is thought to act as an innate tumor suppressive mechanism that curbs expansion of cells harboring activated c-Myc. c-Myc can therefore act as both tumor promoter and tumor suppressor.

Prior attempts to determine the role of c-Myc in tumorigenesis have employed transgenic mice in which expression of activated c-Myc is targeted to various tissues with tissue-specific promoters. Unfortunately, interpretation of such classical transgenic studies is confounded by the fact that c-Myc is constitutively expressed in the tissue of choice, often throughout development of that tissue. Resulting tissues are therefore the net consequence of the protracted interplay between the various pro- and anti-proliferative activities of c-Myc in that tissue. In contrast, in naturally occurring cancers c-Myc is sporadically activated by somatic mutation in an established adult tissue. Therefore, to explore the immediate effects of acute c-Myc activation we have employed a fusion protein comprising Myc fused to a modified 4-hydroxytamoxifen (4-OHT)-dependent form of the estrogen receptor hormone binding domain. We have targeted this reversibly 4-OHT dependent c-MycERª to pancreatic § cells using the rat insulin promoter. Acute activation of physiological levels of c-Myc in § cells triggers dramatic and rapid involution of all pancreatic islets with concomitant development of diabetes mellitus. Morphological analysis indicates that islet involution occurs through massive § cell apoptosis. Subsequent c-MycERª deactivation, by withdrawal of daily 4-OHT, triggers rapid and synchronous islet regeneration over a period of weeks and affected mice become euglycemic. Thus, the oncogenic action of c-Myc in § cells is completely overwhelmed by the pro-apoptotic action of c-Myc.

We next examined the consequences for c-Myc oncogenesis of suppressing apoptosis, either through over-expression of the apoptosis suppressor Bcl-xL or through loss of the p19ARF tumor suppressor through which c-Myc activates the pro-apoptotic p53 protein. We find that apoptosis suppression by either mechanism curtails c-Myc induced § cell apoptosis and triggers immediate c-Myc-induced islet hyperplasias that progressively develop into malignant adenomas. Deletion of ARF results in a more aggressive, dysplastic, and angiogenic phenotype than does expression of Bcl-XL. We are currently using various markers of § cell differentiation, proliferation and apoptosis to define more accurately the molecular events precipitated by c-Myc activation.
