“…Therefore, it may be possible that stromal fibroblasts are activated by cancer-derived or fibroblast-derived TGF-β in a paracrine or autocrine manner, which leads to the activation of PN production from stromal cells into the tumor microenvironment. Although the reason for the observation of negative-to-low expression of PN in CCA cells has yet to be elucidated, it may be explained by the aberrant PN expression control machinery, particularly, the abnormalities of certain transcription factors (4547) and microRNAs (miRNAs) (48,49). In addition, the high PN-expressing CCA-associated fibroblasts were identified to have low level of miR-1, whereas those with low PN had high miR-1 expression (unpublished data from our group).…”

“…2B , upper panel). YY1 regulates many genes associated with cell growth and differentiation by binding to a consensus DNA sequence GCCATNTT/AANATGGC of targeted genes 27 28 . Chromatin Immunoprecipitation (ChIP) assays showed that YY1 could bind to the 3 potential binding elements in Sox4 promoter ( Fig.…”

“…In fibroblast and osteosarcoma cell lines, ANRIL levels rise in response to a variety of DNA damaging agents via an ATM-induced E2F1 transcription-mediated pathway (29) and ANRIL contributes to pro-inflammatory cytokine expression by binding to YingYang-1 (YY1) in response to NFκB signaling (8). POSTN is regulated by YY1, so it is possible that periostin may be an additional cytokine to IL6/8 regulated by the YY1/ ANRIL complex (30). Considering periostin is commonly produced by stromal cells the relevance of the contribution from malignant cells is unclear.…”
