Session: Ras-related signaling Poster: Protein-level regulation of wild-type and mutant RIT1 by the deubiquitinase USP9X Monday, April 17, 2023, 1:30-5 p.m. Presenter: Amanda Riley (On LinkedIn)
Mutations in the gene RIT1 account for about 13,500 cases of non-small cell lung cancer diagnoses each year, with limited treatment options. Graduate student Amanda Riley, working in the Fred Hutch lab of Alice Berger, Ph.D., will give an update on their work to find targeted therapies for RIT1-driven cancers. They’ve identified a regulator of RIT1, a protein called USP9X. Using mouse models and existing inhibitors of USP9X, the researchers are evaluating this potential drug target. The project is part of Berger’s 7-year NIH MERIT award to pursue targeted therapies for mutations in lung cancer. Berger holds the Innovators Network Endowed Chair at Fred Hutch, follow her on Twitter.
Cancer biology
Major symposium: Targeting RNA splicing in cancer and the immune system Presentation: From splicing to polyadenylation in tumor immunity Sunday, April 16, 2023, 1:55-2:15 p.m. Presenter: Robert Bradley, Ph.D. (On Twitter)
Computational biologist and biophysicist Robert Bradley, Ph.D. will present new work on a biological process that’s growing in attention for its role in controlling cancer growth. Alternative polyadenylation is part of making mRNA and it’s disrupted in many cancers, though it’s not clear how the dysregulation contributes to tumors. Bradley, who holds the McIlwain Family Endowed Chair in Data Science at Fred Hutch, will discuss a CRISPR-Cas9-based screen to test the functional importance of alternative polyadenylation to tumor growth.
Cellular immunotherapy
Minisymposium: Genetically engineered anticancer T cells Presentation: NKTR-255, a polymer-conjugated IL-15, dramatically improves ROR1 CAR-T cell persistence and anti-tumor efficacy in an autochthonous model of ROR1+ lung cancer Sunday, April 16, 2023, 4:10-4:25 p.m. Presenter: Sam Nutt
Using a mouse model of lung cancer that closely resembles human disease, graduate student Sam Nutt in the Fred Hutch lab of Shivani Srivastava, Ph.D. (on Twitter) will present a study on whether NKTR-255, a drug that stimulates the immune system to fight cancer, can improve the anticancer effects of chimeric antigen receptor (CAR) T cells. The Fred Hutch team is using a CAR-T cell targeting the tumor antigen ROR1, which is a marker on many breast and lung cancer patients. Their findings suggest that NKTR-255 treatment improves the persistence and function of ROR1 CAR T cells, and that these two therapies work together to boost immune function in the tumor microenvironment, resulting in significantly improved tumor control. The team is continuing to evaluate the combined approach for treatment of solid tumors. Read more about the lab’s work to develop cellular therapies for solid tumors.
Colorectal cancer risk and prevention
Session: Biological and behavioral factors in cancer surveillance, prevention and survivorship Poster: Evaluation of intra-tumoral pks+ E. coli, enterotoxigenic B. fragilis and Fusobacterium nucleatum and in early onset disease, in colorectal cancer cases Monday, April 17, 2023, 1:30-5:00 p.m. Presenter: Meredith Hullar, Ph.D.
Meredith Hullar, Ph.D., a principal staff scientist at Fred Hutch, studies the gut microbiome and its interplay with diet and cancer risk. She will present a new study that revealed different patterns of microbes in colorectal cancer tumors that are present in patients with early onset colorectal cancer, which has increased in incidence in people who are 50 years old and younger. Since some microbes can help tumors grow, understanding the microbiome may help predict which colorectal cancer patients will have increased odds of lower survival and may support targeted intervention strategies to improve survivorship. Learn more about her work in a Fred Hutch news story.
Session: Aging, immune factors and metabolomics Poster: Association between HLA-KIR allele interaction combinations and density of T-cell subsets in colorectal cancer Monday, April 17, 2023, 1:30-5:00 p.m. Presenter: Claire E. Thomas, Ph.D., MPH (On Twitter)
Session: Diet, alcohol, tobacco use, and other lifestyle factors Poster: Lifestyle and environmental factors in relation to colorectal cancer risk and survival by colibactin tumor mutational signature status Wednesday, April 19, 2023, 9:00 a.m.-12:30 p.m. Presenter: Claire E. Thomas, Ph.D., MPH (On Twitter)
Claire E. Thomas, Ph.D., MPH, a post-doctoral researcher at Fred Hutch, will present two posters looking at genetic and molecular risks underlying colorectal cancer. In the first poster, she examines whether immune function gene combinations are related to T-cell density within colorectal cancer tumors. The findings could help determine how an individual’s genetic background is related to T-cells and immune response to fight cancer.
In a second poster, Thomas will present a study examining whether lifestyle and environmental factors are differentially associated with colorectal cancer risk and survival for cases with and without the mutational signature SBS88. SBS88 is present in some colorectal cancer tumors and is related to production of the genotoxin colbactin from exposure to some strains of Escherichia coli. The findings show that among cases with the SBS88 signature, higher BMI category was associated with worse colorectal cancer outcomes.
Thomas works with Fred Hutch’s Ulrike Peters, Ph.D., MPH, who is a molecular and genetic epidemiologist and holds the Fred Hutch 40th Anniversary Endowed Chair, and with Amanda Phipps, Ph.D., MPH, an epidemiologist. The research team aims to understand underlying genetic risks in cancer and how to intervene. A recent Nature Genetics study from the Peters team identified 100 new genetic risk variants in colorectal cancer.

Meet-the-expert session: Plan to enhance diversity: Opportunities, challenges, best practices and innovative strategies to advance a culture of inclusive excellence at cancer centers Tuesday, April 18, 2023, 7:00-7:45 a.m. Presenter: Christopher Li, M.D., Ph.D. (On LinkedIn)
Christopher Li, M.D., Ph.D., vice president of Faculty Affairs and Diversity at Fred Hutch, is a nationally recognized leader in efforts to ensure that cancer research benefits all people. At AACR, he will insights from his efforts to help build and maintain a diverse, equitable and inclusive workforce at Fred Hutch and to collaborate with leaders at other cancer centers. Li, who holds the Helen G. Edson Endowed Chair for Breast Cancer Research, is also an epidemiologist who studies breast cancer risk factors, breast cancer recurrence and cancer health disparities.
Clinical trials
Major symposium: Sex hormones and cancer Presentation: Sex differences in severe adverse events in patients receiving immunotherapy, targeted therapy, or chemotherapy in Cancer clinical trials: An evidentiary perspective Tuesday, April 18, 2023, 1:25-1:45 p.m. Presenter: Joseph Unger, Ph.D. (On Twitter)
Biostatistician and health services researcher Joseph Unger, Ph.D. will insights based on findings he published in Journal of Clinical Oncology in how women experience greater adverse effects from cancer treatment, whether it’s chemotherapy, targeted therapy or immunotherapy. The data came from more than 23,000 people participating in 202 clinical trials as part of the SWOG Cancer Research Network, which described the study in a blog post. Unger uses big data to understand treatment outcomes and disparities in cancer, with the aim of revealing problems in cancer care that then allow for ways to predict and prevent the issues before they impede patients.
Late-breaking poster session: Clinical research 3 Poster: Biomarker analysis from AMPECT correlating response to nab-sirolimus with TSC1 and TSC2 inactivating alterations Wednesday, April 19, 9 a.m.-12:30 p.m. Presenter: Lee Cranmer, M.D., Ph.D.
