Differences in expression profiling between tumoral colorectal carcinomas subsets and normal tissue and polyps [miRNA]

Colorectal cancer (CRC) is the third leading cause of cancer mortality worldwide. Different pathological pathways and molecular drivers have been described and some of the associated markers are used to select effective anti-neoplastic therapy. This dataset is part of ColPortal, a platform that integrates transcriptomic, microtranscriptomic, methylomic and microbiota data of patients with colorectal cancer. ColPortal also includes detailed information of histological features and digital histological slides from the study cases, since histology is a morphological manifestation of a complex molecular change. In this study, we used miRNA expression arrays to investigate differences between tumoral and normal colorectal tissues and polyps
