Cancer Biology

City of Hope's Department of Cancer Biology offers a multidisciplinary research and training environment in a number of scientific areas, including:
 
  • Biomedical Informatics
  • Cancer Metabolism
  • Cancer Prevention and Diagnosis
  • Developmental Biology
  • Drug Resistance
  • Epigenetics
  • Hormonal Carcinogenesis
  • Genetics
  • Genomics
  • Tumor Biology

 

The department focuses on understanding the basic mechanisms of genetics, gene expression and function, signaling pathways, mutagenesis, DNA repair and epigenetics as they relate to the development and progression of cancer. Researchers within the department collaborate with clinical and basic research programs within City of Hope and with other research centers nationally and internationally. The research team explores mechanisms of cancer development (known as carcinogenesis) and aim to develop powerful approaches to cancer prevention and to improve diagnostic tools for detecting cancer early, when it is most treatable.


Laboratory Research

Shiuan Chen, Ph.D. - Chair & Professor - Hormones and Cancer: Chemoprevention
Dr. Chen has studied the role of aromatase in breast cancer development for more than 20 years. Currently Dr. Chen's research explores the mechanisms of endocrine resistance in breast cancer cells and seeks to understand the structure-function relationship of the aromatase protein in order to develop chemoprevention strategies using phytochemicals with anti-aromatase activity. His laboratory also investigates the impact of environmental chemicals on human health by modulating aromatase activity and expression.
 
Susan Kane, Ph.D. - Associate Chair & Professor - Drug Resistance
Dr. Kane's lab studies the molecular and cellular mechanisms of drug resistance to learn more about the mechanism of action of anticancer drugs, why treatments fail and which patients will best respond to specific therapies.
 
WenYong Chen, Ph.D. – Associate Professor - Epigenetics, Cancer and Aging
Dr. Chen's lab deciphers roles and functions of epigenetic regulators and determines their differential contribution to cancer and longevity, and through which, to develop approaches to improve cancer treatment, reduce cancer risk and promote healthy aging.
 
Gerald Holmquist, Ph.D. – Professor Emeritus
 
Mei Kong, Ph.D. – Assistant Professor - Signal Transduction and Cancer Metabolism
Dr. Kong's research lab aims to delineate the strategies used by tumor cells to survive periods of metabolic stress and then to develop novel therapies targeting nutrient sensing pathways of neoplastic cells. Currently their research focuses on protein phosphatase 2A (PP2A) complexes in regulation of cancer cell survival upon nutrients deprivation.
 
Timothy O'Connor, Ph.D. – Professor - DNA repair, mutagenesis and cancer
Dr. O'Connor's lab is interested in DNA repair mechanisms, the biological consequences of repair failure, exploiting DNA repair mechanisms for therapeutic benefit and how DNA repair mechanisms can be used to control the epigenome of cells.
 
Arthur Riggs, Ph.D. – Adjunct Professor (Chairperson-Diabetes and Director Emeritus, BRI) - DNA Methylation and Mammalian Gene Regulation
Dr. Riggs' lab research is broad-based and encompasses chromatin structure-function and gene regulation. Current studies include epigenetic changes in early mouse development, including demethylation mechanisms.
 
Judith Singer-Sam, Ph.D. – Professor Emeritus –Epigenetics and Developmental Biology
Monoallelic expression is a characteristic of genes that are implicated in certain inherited disorders of the CNS as well as some cancers. Using clonal CNS-derived neural stem cells as a model system, Dr. Sam's group is studying possible mechanisms for such expression.
 
S. Emily Wang, Ph.D. – Associate Professor - Growth Factors and Cancer
Dr. Wang's group focuses on the role of signaling by growth factor receptors and oncogenes in cancer progression as well as the development of molecular therapeutics based on mechanistic study.

NEWS & UPDATES
  • We’ve seen it in science fiction: The aliens begin terra-forming a planet to create a friendly habitat that gives them, not the inhabitants, all the advantages when the colonization begins. Turns out, cancer does essentially the same thing when it metastasizes, according to new research from City of Hope. The f...
  • Equipping the immune system to fight cancer – a disease that thrives on mutations and circumventing the body’s natural defenses – is within reach. In fact, City of Hope researchers are testing one approach in clinical trials now. Scientists take a number of steps to turn cancer patients’ T cells – white b...
  • As treatments for lung cancer become more targeted and effective, the need for better technology to detect lung cancer mutations becomes increasingly important. A new clinical study at City of Hope is examining the feasibility of using blood and urine tests to detect lung cancer mutations, potentially allowing ...
  • When it comes to breast cancer risk, insulin levels may matter more than weight, new research has found. The study from Imperial College London School of Public Health, published in the journal Cancer Research, indicates that metabolic health – not a person’s weight or body mass index – increases breast cancer ...
  • No one ever plans to have cancer – and there’s never a good time. For Homa Sadat, her cancer came at a particularly bad time: just one year after losing her father to the pancreatic cancer he had battled for two years. She was working a grueling schedule managing three commercial office buildings. She’d just [&...
  • Patients at City of Hope – most of whom are fighting cancer – rely on more than 37,000 units of blood and platelets each year for their treatment and survival. Every one of those units comes from family, friends or someone who traded an hour or so of their time and a pint of their […]
  • Surgery is vital in the treatment of cancer – it’s used to help diagnose, treat and even prevent the disease – so a new colorectal cancer study linking a decrease in surgeries for advanced cancer to increased survival rates may raise more questions than it answers for some patients. The surgery-and-surviv...
  • Age is the single greatest risk factor overall for cancer; our chances of developing the disease rise steeply after age 50. For geriatric oncology nurse Peggy Burhenn, the meaning is clear: Cancer is primarily a geriatric condition. That’s why she is forging inroads in the care of older adults with cancer. Burh...
  • One of American’s great sportscasters, Stuart Scott, passed away from recurrent cancer of the appendix at the young age of 49. His cancer was diagnosed when he was only 40 years old. It was found during an operation for appendicitis. His courageous fight against this disease began in 2007, resumed again with an...
  • When Homa Sadat found a lump in her breast at age 27, her gynecologist told her what many doctors say to young women: You’re too young to have breast cancer. With the lump dismissed as a harmless cyst, she didn’t think about it again until she was at a restaurant six months later and felt […]
  • What most people call a “bone marrow transplant” is not actually a transplant of bone marrow; it is instead the transplantation of what’s known as hematopoietic stem cells. Such cells are often taken from bone marrow, but not always. Hematopoietic stem cells are simply immature cells that can ...
  • Doctors have long known that women with a precancerous condition called atypical hyperplasia have an elevated risk of breast cancer. Now a new study has found that the risk is more serious than previously thought. Hyperplasia itself is an overgrowth of cells; atypical hyperplasia is an overgrowth in a distorted...
  • Don’t kid yourself. Just because it’s mid-January doesn’t mean it’s too late to make resolutions for a happier, and healthier, 2015. Just consider them resolutions that are more mature than those giddy, sometimes self-deluded, Jan. 1 resolutions. To that end, we share some advice from Cary A. Presant, M.D., an ...
  • Sales and marketing executive Jim Murphy first came to City of Hope in 2002 to donate blood for a friend who was being treated for esophageal cancer. The disease is serious. Although esophageal cancer accounts for only about 1 percent of cancer diagnoses in the U.S., only about 20 percent of patients survive at...
  • Aaron Bomar and his family were celebrating his daughter’s 33rd birthday in September 2014 when he received alarming news: According to an X-ray taken earlier that day at an urgent care facility, he had a node on his aorta and was in danger of an aneurysm. Bomar held hands with his wife and daughter and s...
