BACKGROUND & AIMS Epithelial stem cells in the stomach are responsible for constant renewal of the epithelium through generation of multiple gastric cell lineages that populate the gastric glands. However, gastric stem or progenitor cells have not been well-characterized because of the lack of specific markers that permit their prospective recognition. We(More)
Head and neck squamous cell carcinoma represents a complex set of neoplasms arising in diverse anatomical locations. The site and stage of the cancer determine whether patients will be treated with single or multi-modality therapy. The HDAC inhibitor LBH589 is effective in treating some haematological neoplasms and shows promise for certain epithelial(More)
Oncogene-induced senescence (OIS) is a tumor-suppressive mechanism typified by stable proliferative arrest, a persistent DNA damage response, and the senescence-associated secretory phenotype (SASP), which helps to maintain the senescent state and triggers bystander senescence in a paracrine fashion. Here, we demonstrate that the tumor suppressive histone(More)
Type 2 diabetes involves insulin resistance and β-cell failure leading to inadequate insulin secretion. An important component of β-cell failure is cell loss by apoptosis. Apoptosis repressor with caspase recruitment domain (ARC) is an inhibitor of apoptosis that is expressed in cardiac and skeletal myocytes and neurons. ARC possesses the unusual property(More)
Type 2 diabetes involves insulin resistance and b-cell failure leading to inadequate insulin secretion. An important component of b-cell failure is cell loss by apoptosis. Apoptosis repressor with caspase recruitment domain (ARC) is an inhibitor of apoptosis that is expressed in cardiac and skeletal myocytes and neurons. ARC possesses the unusual property(More)
Despite the identification of several oncogenic driver mutations leading to constitutive JAK-STAT activation, the cellular and molecular biology of myeloproliferative neoplasms (MPN) remains incompletely understood. Recent discoveries have identified underlying disease-modifying molecular aberrations contributing to disease initiation and progression. Here,(More)
Multiple endocrine neoplasia type 1 (MEN1) is a genetic disorder characterized by tissue-specific tumors in the endocrine pancreas, parathyroid, and pituitary glands. Although tumor development in these tissues is dependent upon genetic inactivation of the tumor suppressor Men1, loss of both alleles of this gene is not sufficient to induce these cancers.(More)
