Disease Focus: Cancer
Preclinical development of a pan Bcl2 inhibitor for cancer stem cell directed therapy
Cancer is the leading cause of death for individuals under 85. Relapse and metastatic disease are the leading causes of cancer related mortality. Anti-apoptotic BCL2 family member overexpression has been shown to promote disease progression in both chronic myeloid leukemia (CML) and prostate cancer. Andr., the emergence of cancer stem cells (CSC) promotes apoptosis resistance […]
Niche-Focused Research: Discovery & Development of Hematopoietic Regenerative Factors
Bone marrow and peripheral blood transplantation utilizing blood stem cells can provide curative treatment for patients with cancers and non-cancerous diseases of the blood and immune systems. Such treatments can be curative because the stem cells contained within the bone marrow or peripheral blood of healthy donors are capable of replacing the entirety of the […]
The role of neural stem cells in cerebellar development, regeneration and tumorigenesis
Stem cells have the remarkable ability to renew themselves and to generate multiple different cell types. This allows them to generate normal tissues during development and to repair tissues following injury, but at the same time, renders them highly susceptible to mutations that can result in cancer. Only by understanding the signals that control growth […]
Epigenetics in cancer stem cell initiation and clinical outcome prediction
Cancer is responsible for approximately 25% of all deaths in the US and other developed countries. For women, breast and lung cancers and for men, cancers of prostate and lung are the most prevalent and the most common cause of deaths from cancer. While a large number of treatment modalities such as surgery, chemotherapy, radiation […]
Combinatorial Chemistry Approaches to Develop LIgands against Leukemia Stem Cells
Various cells and organs in the human body originate from a small group of primitive cells called stem cells. Human cancer cells were also recently found to arise from a group of special stem cells, called cancer stem cells (CSCs). At present, cancer that has spread throughout the body (metastasized) is difficult to treat, and […]
Mechanisms of Hematopoietic stem cell Specification and Self-Renewal
During an individual’s lifetime, blood-forming cells in the bone marrow called hematopoietic stem cells (HSCs) supply all the red and white blood cells needed to sustain life. These blood stem cells are unique because they can make an identical copy of themselves (self-renew). Disorders of the blood system can be terminal, but such diseases may […]
Mechanisms Underlying the Responses of Normal and Cancer Stem Cells to Environmental and Therapeutic Insults
Adult stem cells play an essential role in the maintenance of tissue homeostasis. Environmental and therapeutic insults leading to DNA damage dramatically impact stem cell functions and can lead to organ failure or cancer development. Yet little is known about the mechanisms by which adult stem cells respond to such insults by repairing their damaged […]
Stem Cells for Immune System Regeneration to Fight Cancer
This proposal will define the biology of stem cell engineering to produce a cancer-fighting immune system. The immune system protects our body against most outside threats. However, it frequently fails to protect us from cancer. The T cell receptor (or TCR), a complex protein on the surface of an immune cell (or lymphocyte), allows to […]
Derivation and Characterization of Myeloproliferative Disorder Stem Cells from Human ES Cells
Cancer is the leading cause of death for people younger than 85. High cancer mortality rates related to resistance to therapy and malignant progression underscore the need for more sensitive diagnostic techniques as well as therapies that selectively target cells responsible for cancer propagation. Compelling studies suggest that human cancer stem cells (CSC) arise from […]
Stem Cells in Lung Cancer
Lung cancer is the most deadly cancer worldwide and accounts for more deaths than prostate cancer, breast cancer and colon cancer combined. Non small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. The current 5-year survival rate for all stages of NSCLC is only 15%. Although early stage lung cancer has […]
