Project description:Comparing to matched normal mucosa, WTX was lost in most of human colorectal cancers (Zhang et al., 2016). We analyzed the microRNA expression profiling among WTX low human colorectal cancer tissues and matched adjacent WTX high normal colorectal mucosa. The aimed to identify the unique signature of miRNAs which related to WTX loss in human colorectal cancers.

Project description:Colorectal cancer remains the leading cause of cancer death worldwide. The 5-year annual survival is less than half of the incidence rate that is predominantly due to late diagnosis of the disease striking the very urgent clinical necessity for biomarkers capable of detecting cancer malignancy at an early onset. During neoplastic transformation, cells undergo several behavioral changes that subsequently result in defects in cell division, immune tolerance, inflammation, and cellular death mechanisms. These processes lead to the development of tumor antigens (TA) that evoke an immune response and subsequent generation of antibodies against self-proteins, called autoantibodies (AAbs). This study aims to identify autoantibody biomarkers in patient’s sera for early screening of the cancer. High-density human proteome array having approximately 17,000 full-length recombinant human proteins were used in the study. The generation of an autoimmune response against important cancer-linked pathways could be important in terms of screening for the disease. The process of immune surveillance starts as tumorigenesis begins and hence autoantibodies can be detected in a very early stage of cancer. Moreover, AAbs can be easily extracted from blood serum through the least invasive test for disease screening.
Project description:Normal human colorectal mucosa was sampled at points along the colon. Experiment Overall Design: Normal human colorectal mucosa, cecum, ascending, transverse, sigmoid and rectum
Project description:For the understanding intrinsic cancer cell signatures and the surrounding microenviroment, we provide single-cell 3' RNA sequencing dataon 63,689 cells from 23 CRC patients with 23 primary colorectal cancer and 10 matched normal mucosa samples. Analysis of primary colorectal cancer and normal mucosa samples depicts a comprehensive cellular landscape of colorectal cancer and potential cellular interaction, which would be a valuable resource for the development of therapeutic strategies.
Project description:DNA methylation in colorectal cancer diagnosis. The Illumina GoldenGate Methylation Cancer Panel I was used to select a set of candidates markers informative of colorectal cancer diagnosis from 807 cancer-related genes. In the discovery phase, tumor tissue and paired adjacent normal mucosa from 92 colorectal patients were analyzed.
