Loss of polarity protein Par3 in the intestinal epithelium promotes colitis‐associated colorectal cancer progression by damaging tight junction assembly

Abstract: Partitioning defective 3 (Par3) is a polarity protein critical in establishing epithelial cell polarity and tight junctions (TJs). Impaired intestinal epithelial barrier integrity is closely associated with colitis‐associated colorectal cancer (CRC) progression. According to the GEO and TCGA database analyses, we first observed that the expression of Par3 was reduced in CRC patients. To understand how Par3 is related to CRC, we investigated the role of Par3 in the development of CRC using an in vivo genetic ap… Show more

“…Its deficiency allows penetration of pathogenic bacteria and endotoxins into the intestinal submucosa, activating the TLR4/MyD88/NF-κB signaling pathway. This activation promotes inflammation-driven CRC development, suggesting Par3 as a potential molecular marker for early-stage CRC diagnosis [ 74 ]. TLRs, essential recognition receptors for innate immune cells, activate inflammatory processes.…”
