项目摘要
DESCRIPTION (provided by applicant):
This proposal describes a 5 year training program for the development of an independent translational academic research program. The candidate has completed a structured residency training in Medicine and is completing Gl Fellowship training this year at Vanderbilt University. The proposed program will promote the command of transcriptional corepressor biology, as applied to intestinal inflammatory disease and its sequella. Dr. Scott Hiebert will be the primary mentor for the candidate's scientific development. He is a recognized leader in the field of transcriptional repression and has trained numerous postdoctoral fellows and graduate students. To enhance training, the program will enlist the expertise of Dr. Keith Wilson (Professor of Medicine) and Dr. Brent Polk (Professor of Pediatrics) who have considerable expertise in the field of mucosal immunology and inflammatory bowel disease. In addition, an advisory committee of highly regarded physician scientists will provide scientific and career advice. MTGR1 (Myeloid Translocation Gene, Related-1) is a member of a gene family originally identified as targets of chromosomal translocation in acute myeloid leukemia (AML). Recent work from our laboratory has shown that MTGR1 plays a role in intestinal differentiation, wound healing, and inflammation. We have found that MTG proteins bind TCF4 and repress WNT signal transduction resulting in de-regulation of TCF4 targets. Mtgr1-null animals develop a severe and persistent colitis in response to gut injury and exhibit abnormal enterocyte migration along the crypt-villus access, implicating MTGR1 as a regulator of crypt-villus architectural patterning. Given the role of MTG family members in hematopoietic malignancy, the ability of MTGR1 to modulate WNT signaling, and that loss of MTGR1 results in sensitization to gut injury, we hypothesize that MTGR1 plays a role in inflammatory bowel disease and may contribute to tumorigenesis arising in an inflammatory background. The specific aims include 1) Defining the role of MTGR1 in proliferation, apoptosis, and migration using cell lines derived from wild-type and Mtgr1-/- mice 2) Dissect the contribution of MTGR1 to carcinogenesis using animal models of inflammatory and non-inflammatory carcinogenesis. Inflammatory Bowel Disease (IBD) is predominantly a disease of the 20th century with highest prevalence in developed countries. Abnormalities in MTG family member function may contribute to IBD susceptibility or pathology and potentially to colitis associated carcinoma and thus may offer therapeutic targets for treatment and or prevention of IBD or IBD associated diseases.
描述(由申请人提供):
该提案描述了一个为期5年的培训计划,以发展一个独立的翻译学术研究计划。候选人已经完成了医学方面的结构化住院医师培训,并将于今年在范德比尔特大学完成GI奖学金培训。拟议的计划将促进指挥转录辅阻遏物生物学,适用于肠道炎症性疾病及其后遗症。Scott Hiebert博士将是候选人科学发展的主要导师。他是转录抑制领域公认的领导者,并培养了许多博士后研究员和研究生。为了加强培训,该计划将争取基思威尔逊博士(医学教授)和布伦特波尔克博士(儿科教授)谁在粘膜免疫学和炎症性肠病领域有相当的专业知识的专业知识。此外,一个由德高望重的医生科学家组成的咨询委员会将提供科学和职业建议。MTGR 1(Myeloid Translocation Gene,Related-1)是一个基因家族的成员,最初被鉴定为急性髓细胞白血病(AML)中染色体易位的靶基因。我们实验室最近的工作表明,MTGR 1在肠道分化、伤口愈合和炎症中发挥作用。我们已经发现,MTG蛋白结合TCF 4并抑制WNT信号转导,导致TCF 4靶点的失调。MTGR 1基因缺失的动物在肠道损伤后会发生严重的持续性结肠炎,并表现出异常的肠上皮细胞沿隐窝-绒毛通路沿着迁移,表明MTGR 1是隐窝-绒毛结构模式的调节因子。考虑到MTG家族成员在造血系统恶性肿瘤中的作用,MTGR 1调节WNT信号传导的能力,以及MTGR 1的缺失导致对肠道损伤的敏感性,我们假设MTGR 1在炎症性肠病中起作用,并可能有助于炎症背景下产生的肿瘤发生。具体目标包括:1)使用来自野生型和Mtgr 1-/-小鼠的细胞系确定MTGR 1在增殖、凋亡和迁移中的作用; 2)使用炎性和非炎性致癌作用的动物模型剖析MTGR 1对致癌作用的贡献。炎症性肠病(IBD)是世纪的主要疾病,在发达国家中发病率最高。MTG家族成员功能的缺失可能导致IBD易感性或病理学,并可能导致结肠炎相关癌,因此可能为治疗和/或预防IBD或IBD相关疾病提供治疗靶点。
