The Leadership Team is the organizing body for Center-level planning and decision-making. The group i) monitors progress toward workforce strategy and excellence, ii) reviews intracenter pilot projects, iii) plans annual site visits with NCI staff and the External Advisory Board, and iv) discusses candidate cross-consortium projects in consultation with the NCI.
Data Management
Investigator

The Data Manager is the interface between the MC2 Center Research Coordinating Hub and the specific resource-development activities of the SASCO Center. The data manager i) ensures standards and platforms put forth by the Resource and Data Sharing Working Group are transmitted to the Center, ii) communicates Center-specific challenges with resource sharing to the MC2 Center, and iii) facilitates the timely sharing of data and resources.
Andrea Denton presented an update of the SASCO Data Management effort in November 2023.
In December 2024, Andrea presented a Citation Strategy in Practice seminar.
Andrea led the January 2025 SASCO Seminar, leading a LabArchives primer. You will find her slides, video and follow-up comments HERE.
Intra-Center Pilot Projects
The SASCO Center offers Intra-Center Pilot Projects with cost-matched support from the UVA Comprehensive Cancer Center and UVA Office of the Vice-President for Research. Details on the Intra-Center Pilot Projects are released as an annual Request For Applications.
The Systems Analysis of Stress-Adapted Cancer Organelles (SASCO) Center is an NCI-funded U54 Cancer Systems Biology Consortium research center at UVA. SASCO investigators are dedicated to the study of cancer cell biology using integrated experimental and computational methods, especially where computational inferences inform experimental hypotheses. In such projects, a “measure-model-test” cycle is typical. Read more about specific SASCO research themes on oncogenic stress on organelles in three cancer settings, the collaborative research core, and the investigator team at the SASCO website.
In its second year (beginning September 1), the Center will support $100,000 of pilot funding to UVA principal investigators. The broad goal of pilot funding is to introduce investigators to cancer systems biology research questions and approaches. While alignment with the theme of oncogenic stress on organelles is preferred, it is not a required component of a successful pilot project application. Pilot funding applicants can propose projects that integrate with existing SASCO themes, or they can propose new cancer systems biology projects. To aid applicants in designing their approach, the overall aims of the SASCO proposal are available upon request. Prospective applicants are encouraged to contact U54 Center MPI Matthew Lazzara with questions and to discuss project alignment.

High-Content Imaging & Analysis Core
Investigators


The High-Content Imaging & Analysis Core provides the three SASCO Center projects with experimental and computational resources to analyze different biological samples by multiplexed fluorescence microscopy and to extract quantitative data from microscopy-based images. The core will develop, validate, and apply highly multiplexed (iterative) imaging approaches, integrate subcellular imaging data collected across multiple rounds of iterative imaging, and build customized tools for image analysis, feature recognition, and extraction. The generated multi-parametric datasets will address specific needs of each project, enabling model-experiment iterations involving diverse cancer drivers, signaling pathways, and subcellular organelles in multiple biological contexts. Aim #1 supports the development, validation, and application of highly multiplexed immunofluorescence staining and imaging procedures to measure molecular features at cellular, subcellular, and organelle resolution. These procedures will enable the molecular analysis of mitotic signaling pathways and recruitment patterns in metaphase chromosomes derived from breast cancer organoids (Project 1), mitochondrial morphology, cell signaling and metabolic enzymes in colorectal cancer cells and tumors (Project 2), and post-translational modifications of key EGFR signaling molecules, protein-protein interactions, and their subcellular localization in glioblastoma cells (Project 3). Aim #2 customizes tools for quantitative image analysis, including image alignment and tracking, segmentation of cells and subcellular structures, as well as feature extraction and recognition. The High-Content Imaging & Analysis Core provides all three projects the necessary expertise and tools for quantifying information about cells, cultures, and tissues from image data to support hypothesis generation and model testing related to the overall hypotheses of the SASCO Center.
The SASCO Outreach Core serves to promote the broad use of systems biology in cancer research beyond the University of Virginia (UVA); disseminate and increase accessibility of computational and experimental approaches developed within the SASCO Center to the cancer research enterprise; and recruit the involvement of investigators, cancer biologists, and clinicians to enrich the research and environment of the Center. The Outreach Core has three initiatives. First, undergraduates from around the country will participate in summer research experiences in SASCO laboratories through existing outstanding summer research internship programs at the Schools of Medicine and Engineering & Applied Science. Second, we will develop a series of videos designed to introduce clinicians to systems concepts and approaches toward enabling stronger collaborations between clinicians and systems biologists. The videos will be piloted for effectiveness within a Clinical and Translational Science Award program that includes UVA and other health centers in the Commonwealth of Virginia. Third, the SASCO Outreach Core will enable summer scholar-in-residence positions for faculty from other colleges and universities to develop research projects in SASCO laboratories. The goal of this third aim is to both establish new systems-based research projects at colleges and to increase the visibility of systems approaches in their curricula.

Initiative One - 2025: Quantifying mitochondrial morphology and topology in colorectal cancer
A project under the SASCO umbrella focusing on studying the effect, and ultimately mechanism by which mitochondrial morphology and topology influences the distribution of proteins within the cell. My role in the project is to work with mitochondrial immunofluorescence data in order to develop a meaningful way to quantitatively describe mitochondrial morphology and topology, ultimately aiming to develop a set of features that can serve as a mitochondrial “fingerprint” for cell lines with distinct mitochondrial networks.

Initiative One - 2025: Investigating the Feedback loop between FOXM1 and Cyclin F in Breast Epithelial Cells
My project will investigate how CCNF regulates FOXM1 activation throughout the cell cycle by combining protein measurements with transcriptional snapshots and computational modeling. First, I’ll synchronize cells at key cycle phases and directly quantify Foxm1 and Cyclin F protein levels at each stage. Next, I’ll use RNA-seq data from those synchronized cultures—and from breast cancer samples—to infer stage-specific FOXM1 transcriptional activity. Finally, I’ll map those activity profiles onto a model to reveal how CCNF-driven timing shapes FOXM1 dynamics and downstream regulatory programs.
