High Soluble Fiber Promotes Colorectal Tumorigenesis Through Modulating Gut Microbiota and Metabolites in Mice.

Background & Aims: Dietary fibers are mainly fermented by the gut microbiota, but their roles in colorectal cancer (CRC) are largely unclear. Here, we investigated the associations of different fibers with colorectal tumorigenesis in mice.

Methods: Apc mice and C57BL/6 mice with azoxymethane (AOM) injection were used as CRC mouse models.

Dysregulated microRNAs and their predicted targets associated with endometrioid endometrial adenocarcinoma in Hong Kong women.

The objective of this study, a parallel study to global gene expression profiling, was to identify dysregulated microRNAs (miRNAs) associated with endometrioid endometrial adenocarcinoma (EEC), examine their correlation with clinico-pathological characteristics and identify predicted target genes of the dysregulated miRNAs. Using real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR), profiling of miRNA expression was performed in 30 EECs and 22 normal counterparts in which genome-wide gene expression had been previously profiled and reported. Clustering analysis identified 30 miRNAs which were significantly dysregulated in EEC.
