Sexual recombination and virulence in the success of African trypanosomes
In disease-causing organisms, hybridization allows for the transfer of traits such as virulence and drug resistance. Dr. Mabel Tettey will investigate how hybridization impacts African trypanosomiasis outbreaks caused by the parasite Trypanosoma brucei. Dr. Tettey will assess the degree of hybridization occurring in African trypanosome endemic areas, explore the impact of hybridization on virulence, and identify the key molecules involved in this process. She will conduct these experiments in Dr. Michael Grigg’s lab at the National Institute of Allergy and Infectious Diseases. These studies may enable the development of effective disease control strategies against African trypanosomes.
As a graduate student in Dr. Keith Matthews’ lab at the University of Edinburgh, Tettey examined the function of released peptidases in the transmission of African trypanosomes. Specifically, Dr. Tettey identified the genes that dominate quorum sensing signal in African trypanosomes. With her extensive background in trypanosome biology, Dr. Tettey will now examine the role of hybridization in trypanosome virulence.

Bookmarking the chromosomes and its role in cellular memory
Cellular memory can be defined as the ability of a cell to transmit all its identifying functions to daughter cells during cell division. This ability to ‘remember’ identity is crucial to the development of multicellular organisms, as evidenced when cells lose their identity and degenerate or become cancerous. Conversely, our ability to alter cell state, such as the generation of induced pluripotent stem (iPS) cells from differentiated cells, has become a promising therapeutic tool. Therefore, understanding how cells establish, maintain, and change identity will further our understanding of processes central to cellular development, disease progression, and therapy production. One mechanism for cellular memory is the ability to re-establish the transcriptional program following mitosis, which may function through bookmarking, the process of DNA-binding factors marking genes on condensed mitotic chromosomes to facilitate gene expression following mitosis. The main objective of this proposal is to analyze the mechanisms of bookmarking. I outline three independent approaches to characterize quantitatively the mechanisms of bookmarking. Using these approaches, I will test the hypothesis that histone variants and pluripotency factors function as bookmarkers to maintain the stem cell state. Lastly, I will perform an unbiased screen to identify putative bookmarking factors specific to embryonic stem cells.

Sex differences in glioblastoma: a microglia perspective
Cancer affects men and women differently. For example, glioblastoma, the most aggressive form of brain cancer, has a male-biased incidence rate and poorer response to standard treatments in men versus women. My research investigates the genetic and molecular basis of sex differences in glioblastoma from the perspective of microglia, the resident immune cells of the brain. Microglia are a major player in the brain tumor microenvironment and promote tumor growth and metastasis. Using XX and XY human microglia isolated from healthy brain regions and brain tumors, I am identifying sex-biased genes and biological pathways that are responsible for establishing sexually dimorphic brain tumor microenvironments. Further, I am testing how possessing an XX or XY sex chromosome complement drives the observed genome-wide sex-biased gene expression patterns in microglia, in particular, through X-linked genes that aberrantly escape X chromosome inactivation or homologous X-Y gene pairs with imbalanced expression or function. I anticipate that my research will lay the groundwork for more effective and sex-specific treatments for glioblastoma.

Deciphering cell-specific metabolic changes in PDAC
Pancreatic cancer represents 3% of all new cancer cases in the United States, yet it has the worst 5-year survival rate of all cancer types. While many cancer types display durable responses to cancer immunotherapy, which harnesses the cytotoxic activity of the immune system to treat malignancies, immunotherapy has largely failed to treat pancreatic ductal adenocarcinoma (PDAC). The complex tumor microenvironment of PDAC likely underlies the refractory response of PDAC to immunotherapy, including immune checkpoint blockade (ICB). One example of a known mechanism that aids immune evasion by PDAC is the presence of desmoplastic stroma that hinders the infiltration of cytotoxic T cells. In addition to exclusion of immune infiltrate, the cytotoxic T cells that are present within the microenvironment are dysfunctional. Nutrient availability within the tumor environment likely impacts the function of cytotoxic T cells and research in immunometabolism is of growing interest. Understanding cell-specific metabolic changes within GEMMs has been hindered by a lack of mouse models that properly recapitulate the tumor microenvironment and lack of tools able to properly isolate cells in a way that preserves the integrity of the metabolites. My project will use a GEMM of PDAC, congenic markers, and cancer cell-specific surface tags in order to rapidly purify and perform metabolomics of both cancer cells and T-cells. Using this technique, I hope to identify metabolic pathways that are hindering immune cell proliferation and cytotoxic capabilities to reinvigorate the immune microenvironment for tumor control and in response to ICB.

The role of ribosomal protein gene deletions in liver cancer
Hemizygous deletions of ribosomal protein genes (RPGs) are recurrently found across human cancers, yet their role in tumorigenesis is poorly understood. Here, I propose to systematically investigate the function of RPG hemizygosity in cancer, using hepatocellular carcinoma (HCC) as a model, by exploring two specific hypotheses. First, based on genomic data from HCC and other tumors, and emerging biochemical evidence for mRNA-specific translational control by individual RPs, I hypothesize that RPGs act as haploinsufficient tumor suppressor genes by selectively altering the translation of oncogenic and/or tumor-suppressive mRNAs. I will assess the contribution of RPG hemizygosity to tumor initiation, progression and maintenance, and analyze its impact on mRNA translation. Second, given that RPG deletions are almost invariably hemizygous and strongly associate with loss of the p53 tumor suppressor gene, I hypothesize that RPG hemizygosity renders cancer cells more vulnerable to perturbations of ribosome homeostasis. I will examine the effects of p53 restoration and further RPG depletion in RPG hemizygous cells, and perform a ribosome homeostasis-focused screen for RPG hemizygosity-specific tumor dependencies. Together, the proposed studies may provide an explanation for the striking patterns of RPG loss in human cancer, with potential broad implications for both fundamental biology and cancer treatment.

Dynamic interactions of hippocampal-prefrontal circuits for flexible behavior
Dr. Shih-Yi Tseng is interested in how the brain coordinates the many functions we use to navigate our way through the world. During her Ph.D. research she studied a large population of neurons to illustrate that neural coding enables these functions and is distributed throughout the cortex. In her fellowship, Tseng will now decipher how two areas of the brain work together to enable the flexible behavior required for navigation.
Tseng’s thesis research in Dr. Christopher Harvey’s lab at Harvard University examined the functional organization of the cortex in supporting sensing, planning, and action to navigate towards a goal location in dynamically changing environments. By tracking the activity of 90,000 brain cells in mice, Tseng found that information about tasks and behavior is spread out across the cortex. Her work suggests that this part of the brain possesses a vast capacity to integrate complex features of behavior and surroundings to guide decisions.
In Dr. Loren Frank’s lab at UC San Francisco, Tseng will now investigate the dynamic interactions between the hippocampus (HPC) and prefrontal cortex (PFC) to enable flexible behavior. The HPC is important for learning and memory, whereas the PFC is crucial for decision-making. These regions need to coordinate during tasks such as navigation, yet how such coordination occurs is not known. Tseng will use multi-area electrophysiology, optogenetic manipulations, and computational methods to determine the HPC-PFC interactions needed for flexible behavior, and to evaluate how their coupling enables these regions to perform their individual functions. This research will provide fundamental insights into HPC-PFC coupling and may reveal ways in which this process goes awry in neuropsychiatric disorders.

Effects of regulatory network divergence on drug resistance in Candida
The human pathogen Candida albicans’ genome varies substantially between clinical isolates, yet it is currently unknown how this variation affects infection. Since many genetic variants are located in gene regulatory sequences, Dr. Petra Vande Zande predicts that there is substantial divergence in gene-regulatory networks between different C. albicans isolates that modifies their fitness. Dr. Vande Zande will use gene expression data from different isolates to model gene regulatory networks and identify key differences that impact fitness. Vande Zande will conduct these experiments in Dr. Anna Selmecki’s lab at the University of Minnesota. This research will provide direct insight into genetic differences that impact C. albicans infections. It may also provide clues into other genetically diverse systems with differences in gene-regulatory networks, including human cancers.
As a graduate student in Dr. Patricia Wittkopp’s lab at the University of Michigan, Vande Zande studied gene expression in the context of adaptive evolution. In particular, Dr. Vande Zande discovered that mutations affecting a gene’s expression from a distance are more pleiotropic and more detrimental to fitness than mutations occurring proximally to the gene of interest. With her experience in the evolution of gene expression, Dr. Vande Zande is now interested in understanding divergence in gene-regulatory networks between different clinical isolates of yeast infections.
