Laboratory Overview

We focus our studies on identification of therapeutic targets among signaling molecules which are involved in tumor-promoting inflammation. Our two-step immunotherapeutic strategy is first to disarm tumor defense systems, and then to activate immune attack from within.

Research Interests
Fighting cancer by activating immune system to search and destroy tumor cells with high precision could overcome the problem of serious side-effects observed after conventional cancer treatments. Recent advances in the understanding interactions between tumor and immune system identified that immune cells accumulated within tumor tissue are essential therapeutic targets for cancer immunotherapy. Dysfunctional immune cell populations within the tumor microenvironment secrete growth factors, promote blood vessel formation and disarm the immune system. Targeting immune cells in tumors poses problems due to the lack of specific therapeutics. We previously developed a novel reagent, CpG-siRNA molecules that allow for specific receptor-mediated delivery of the therapeutic agent (siRNA) into certain immune cell populations. We used CpG-siRNAs to block function of tumor-supporting immune cells, thereby generating potent antitumor immune responses in mice. Our recent studies suggest that the same strategy could restore the antitumor immune responses in cancer patients. Moreover, we used CpG-siRNAs to block oncogenic signaling and induce cell death in several types of human blood cancers, including acute myeloid leukemia (AML). We currently optimize CpG-siRNAs for use against metastatic tumors and multiple gene targets, what should generate novel, more effective and safer therapeutics, expanding treatment options for the benefit of cancer patients.

NEWS & UPDATES
  • Although a stem cell transplant can be a lifesaving procedure for people diagnosed with a blood cancer or blood disorder, the standard transplant may not be appropriate for all patients. This is because the conditioning regimen (the intensive chemotherapy and/or radiation treatments preceding the transplant) is...
  • Brain tumor removal would seem to be the obvious course of action in the wake of a brain tumor diagnosis, but that’s not always the case. Some tumors are too difficult for many surgeons to reach or too close to areas that control vital functions. Removing them just proves too risky. A new device at City [...
  • Hijacking the same sorts of viruses that cause HIV and using them to reprogram immune cells to fight cancer sounds like stuff of the future. Some scientists believe that the future is closer than we think – and are now studying the approach in clinical trials at City of Hope. Immunotherapy is a promising approa...
  • Nausea is the one of the most well-known, and dreaded, side effects of cancer treatment — and with good reason. Beyond the quality-of-life issues that it causes, severe nausea can prevent patients from receiving enough nutrients and calories at a time when they need every edge they can get. A few simple actions...
  • With Labor Day just around the corner, summer is on its way out. But just because summertime is ending doesn’t mean we can skip sunscreen. Protection from ultraviolet (UV) radiation is needed all year round. Exposure to UV radiation — whether from the sun or from artificial sources such as sunlamps used i...
  • Undergoing reconstructive surgery may seem like a forgone conclusion for survivors of breast cancer, but that doesn’t appear to be the case. A new study has found that most breast cancer survivors who undergo a mastectomy decide against surgical reconstruction of their breasts. The reasons for such a deci...
  • Nearly four decades ago, City of Hope began its bone marrow transplant program. Its first transplant reunion celebration was a single patient and his donor, also his brother. This year, City of Hope welcomed hundreds of hematopoietic cell transplant (HCT) recipients to the annual bone marrow transplant/HCT reun...
  • The burgeoning type 2 diabetes epidemic casts a pall over the health of America’s public. New research now shows the looming threat is getting worse. Much worse. A diabetes trends study published earlier this month in the Lancet Diabetes and Endocrinology by researchers at the federal Centers for Disease Contro...
  • An aspirin a day might help keep breast cancer away for some breast cancer survivors, a new study suggests. Obese women who have had breast cancer could cut their risk of a recurrence in half if they regularly take aspirin or other nonsteroidal anti-inflammatory drugs, called NSAIDs, report researchers from the...
  • Christine Crews isn’t only a fitness enthusiast, she’s also a personal trainer and fitness instructor. Being active defines her life. So when she was diagnosed with bladder cancer at age 30, she decided she absolutely couldn’t let the disease interfere with that lifestyle. And it didn’t. For t...
  • Cancer treatment and the cancer itself can cause changes in your sense of taste or smell. These side effects typically subside after treatment ends, but there are ways to help alleviate those bitter and metallic tastes in your mouth. Here are tips from the National Cancer Institute to help keeps tastes and food...
  • Immunotherapy — using one’s immune system to treat a disease — has been long lauded as the “magic bullet” of cancer treatments, one that can be more effective than the conventional therapies of surgery, radiation or chemotherapy. One specific type of immunotherapy, called adoptive T cell thera...
  • Today, when cancer spreads from its original site to other parts of the body, a process known as metastasis, patients face an uphill battle. Treatments are poorly effective, and cures are nearly impossible. Further, incidence rates for these types of cancers are increasing – particularly for cancers that have s...
  • Thanks to the California Institute for Regenerative Medicine (CIRM), high school students across the state gained valuable hands-on experience with stem cell research this summer. City of Hope hosted eight of those students. As part of the CIRM Creativity Awards program, the young scholars worked full time as m...
  • Radiation therapy can help cure many children facing Hodgkin lymphoma and other cancers. When the radiation is delivered to a girl’s chest, however, it can lead to a marked increase in breast cancer risk later in life. A recent multi-institutional study that included City of Hope’s Smita Bhatia, M.D., M.P.H., t...
