    • The present invention provides methods and materials related to the detection of colorectal neoplasm-specific markers (e.g., markers associated with colorectal cancer, markers associated with adenoma) in or associated with a subject's stool sample. In particular, the present invention provides methods and materials for identifying mammals (e.g., humans) having a colorectal neoplasm by detecting the presence and level of indicators of colorectal neoplasia such as, for example, long DNA (e.g., quantified by Alu PCR) and the presence and level of tumor-associated gene alterations (e.g., mutations in KRAS, APC, melanoma antigen gene, p53, BRAF, BAT26, PIK3CA ) or epigenetic alterations (e.g., DNA methylation) (e.g., CpG methylation) (e.g., CpG methylation in coding or regulatory regions of bmp-3, bmp-4, SFRP2, vimentin, septin9, ALX4, EYA4, TFPI2, NDRG4, FOXE1) in DNA from a stool sample obtained from the mammal.
    • 本发明提供与检测与受试者粪便样品相关的结肠直肠肿瘤特异性标志物(例如,与结肠直肠癌相关的标志物,与腺瘤相关的标志物)相关的方法和材料。 特别地,本发明提供了通过检测结肠直肠瘤形成指标(例如长DNA(例如,通过Alu PCR定量))的存在和水平来鉴定具有结肠直肠肿瘤的哺乳动物(例如,人)的方法和材料,以及 肿瘤相关基因改变(例如,KRAS,APC,黑素瘤抗原基因,p53,BRAF,BAT26,PIK3CA中的突变)或表观遗传改变(例如,DNA甲基化)(例如,CpG甲基化)(例如,CpG 在来自哺乳动物的粪便样品的DNA中,bmp-3,bmp-4,SFRP2,波形蛋白,septin9,ALX4,EYA4,TFPI2,NDRG4,FOXE1的编码或调节区中的甲基化)。
