Research Lab Overview

The research focus of the Terence Williams Lab is to elucidate the molecular biology of cancer vulnerability derived from genetic, epigenetic, metabolic and tumor micro-environmental alterations, and to find strategies targeting this vulnerability to improve cancer chemotherapy, radiotherapy, molecularly targeted therapy and immunotherapy.

The Williams Lab is translating its bench findings in the underlying mechanisms of the deregulation of genome surveillance systems and nutrient scavenging/caveolae-mediated endocytosis to clinic for the personalized diagnosis, prognosis and treatment of cancer patients.

The picture on the right shows Tiantian Cui, M.D., Ph.D., an assistant research professor in the Terence Williams Lab, sharing and discussing science at the 2022 conference of the American Association of Cancer Research (AACR) at New Orleans, LA.

Highlights

The overarching goal of our research is to understand the mechanisms of the inherent and acquired resistance of cancer cells to current available treatment modalities, particularly radiotherapy and chemotherapy at the genetic, transcriptomic and proteomic levels.

Such knowledge allows us to design and implement novel therapy strategies for poor-prognosis cancers, including gastrointestinal (pancreatic, esophago-gastric, colorectal and hepatobiliary), thoracic (non-small cell lung cancer), thyroid, and head and neck malignancies. We use various mouse models (transgenic, genetically engineered, patient-derived xenograft and orthotopic models) as well as patient tissues (tumor and normal) in combination with basic molecular and cellular techniques to address the fundamental cancer biological questions about how cancers initiate, develop and progress to aggressive, therapeutically-resistant and metastatic disease.

We identify and validate our biomarkers in clinically-relevant disease model systems for the diagnosis, treatment and prognosis of cancer patients. We collaborate with many other labs at City of Hope, across the U.S. and internationally in five main overlapping research areas with the goal of driving development of new clinical trials:

Caveolae-mediated endocytosis and nutrient scavenging
Oncogene mediated radioresistance
Identifying and targeting novel DNA repair and DNA damage response pathways modulating tumorigenesis and therapeutic response
Developmental therapeutics (e.g., protein-drug conjugates, RNA, radiopharmaceuticals, radioimmunotherapy)
Molecular profiling and predictive biomarkers in immuno-oncology

Dr. Linlin Yang’s poster ‘Targeting KRAS mutant non-small cell lung cancer with EGFR aptamer displaying 3WJpRNA nanoparticles’ at the 2022 conference of the American Association of Cancer Research (AACR) at NOLA

In this study, we assembled novel EGFRaptmer-3WJ-siKRAS mutation targeted nanoparticles to target EGFR-expressing human NSCLC harboring a KRAS^G12C mutation in order to silence KRAS^G12C expression in a tumor-specific fashion. We found that EGFRapt-3WJ-siKRAS^G12Cnanoparticles potently and selectively depleted cellular KRAS^G12C expression, resulting in attenuation of downstream MAPK pathway signaling, cell proliferation, migration/invasion ability, sensitization of NSCLC cells to chemoradiotherapy, and in vivo growth inhibition of KRAS^G12C NSCLC tumor xenografts. Together, this study suggests that the 3WJ pRNA based platform has potential to suppress mutant KRAS activity for the treatment of KRAS-driven human cancers, and warrants further development for clinical translation.

Dr. Tiantian Cui’s poster ‘Caveolin-1 functions as a potential predictive biomarker for JNTX-101, an albumin encapsulated gemcitabine prodrug’ at the 2022 conference of the American Association of Cancer Research (AACR) at NOLA

JNTX-101, an albumin encapsulated gemcitabine prodrug, effectively inhibits pancreatic and lung cancer tumor growth and may hold promise for future clinical development. Cav-1 expression dictates sensitivity to JNTX-101, at least partially through reduced apoptotic cell death. Cav-1 may be a potential predictive biomarker of JNTX-101 efficacy, especially in nutrient deprived conditions.

COH Shared Resources Grant

Dr. Terence Williams and Dr. Tiantian Cui have received a COH Shared Resources Grant in 2021 entitled “Targeting Tumor Endocytosis to Drive Novel Anti-tumor Strategies”. This study will identify individual biomarkers or biomarker signatures that predict for efficacy of albumin uptake and develop pharmacological strategies to increase albumin uptake prior to delivery of novel albumin-conjugated cytotoxic chemotherapeutics (as well as the FDA-approved nab-paclitaxel) or targeted agents, leading to rapid clinical translation of novel and innovative oncologic biomarkers and treatments.

Career Opportunities

The goal of Dr. Williams’ Lab is to revolutionize the management of cancer patients. To help achieve this goal, we are working to develop an innovative and dynamic scientific research team at City of Hope.

To accomplish our mission, we promote an environment for teamwork and learning for all team members at every stage of training (staff scientist level, post-doctoral, graduate and undergraduate).

Specifically, we are looking for enthusiastic, ambitious and self-motivated individuals who thrive in a fast-paced, competitive and challenging research environment, and who can interact well with others as a member of our research family. If you work hard and have a dream to make a significant difference in the health care of cancer patients, we invite you to contact us. Inquiries can be directed to Phyllis Burch at pburch@coh.org.

Veronica Castro-Aceituno, Ph.D., R.D.N., graduated from San Carlos de Guatemala University and became a registered dietitian nutritionist in 2013. With a scholarship from the National Secretariat of Science and Technology of Guatemala, she joined Professor Deok-Chun Yang's laboratory. In 2018, she attained her Ph.D. by investigating the anti-cancer mechanism of various nanoparticles derived from oriental medicinal plants at Kyung Hee University in South Korea. Later, she joined Professor Young-Han Song's team at Hallym University as a postdoctoral researcher. In 2019, Castro-Aceituno attained a grant from the National Research Foundation of South Korea to study the mechanism of activation by tetramerization of Drosophila p53 (Dp53) and the identification of the physiological function of the isoforms of Dp53. She joined the lab of Dr. Terence Williams at City of Hope in July 2021. Her experience lies in the elucidation of the possible anticancer mechanism of new therapies for the treatment of cancer. Castro-Aceituno's research goals are to study tumor metabolism and cancer nutrient scavenging, and to improve the quality of life of cancer of patients by shedding light on interdisciplinary methods that will avoid resistance to treatment and reduce its side effects, including cancer cachexia.

Veronica Castro-Aceituno, Ph.D., R.D.N.

Postdoctoral Fellow

In 2019, Castro-Aceituno attained a grant from the National Research Foundation of South Korea to study the mechanism of activation by tetramerization of Drosophila p53 (Dp53) and the identification of the physiological function of the isoforms of Dp53. She joined the lab of Dr. Terence Williams at City of Hope in July 2021.

Her experience lies in the elucidation of the possible anticancer mechanism of new therapies for the treatment of cancer. Castro-Aceituno's research goals are to study tumor metabolism and cancer nutrient scavenging, and to improve the quality of life of cancer of patients by shedding light on interdisciplinary methods that will avoid resistance to treatment and reduce its side effects, including cancer cachexia.

Sindhu Nair, D.M.D., Ph.D., graduated with a bachelor’s degree in dental surgery (B.D.S.) in 2010 and then completed her D.M.D. residency (master's degree in oral and maxillofacial pathology) in 2014 from Rajiv Gandhi University of Health Sciences, India. Her master's thesis research involved understanding field cancerization and neoangiogenesis in oral squamous cell carcinoma and its correlation with clinicopathological parameters. In 2021, she received her Ph.D. in cancer biology from the University of Alabama at Birmingham, where her dissertation research involved investigating dysregulated alternative splicing of ANXA7 and its functional impact on receptor tyrosine kinase signaling in glioblastoma. Additionally, she characterized EGFR ectodomain mutations giving rise to and sustaining cetuximab resistance in head and neck cancer. She joined Dr. Williams’ lab in 2021 as a postdoctoral fellow. Dr. Nair’s expertise lies in histopathology, molecular mechanisms of signal transduction, endocytic trafficking and mutational causes of therapeutic resistance.
