We examined the role of CCN1/CYR61, an inducible matricellular protein, in LPA-induced signal transduction in PC-3 human prostate cancer cells. We found that both LPA and S1P induced expression of CCN1 and CCN2 within 2–4 h. CCN1 was induced by 18:1-LPA, but not by 18:0-, 18:2-, or 18:3-LPAs. A free fatty acid receptor-4 agonist inhibited LPA-induced CCN1 induction. CCN1 appeared in the ECM within 2 h after LPA addition. LPA caused biphasic activation of Erk MAPK, with an initial peak at 10–20 min followed by a later phase after 6 h. LPA increased adhesion of PC-3 cells to culture substrates (standard culture plates, fibronectin, or extracellular matrix) at 2 h, an intermediate event between early and late LPA signals. Knockdown of CCN1 suppressed LPA-induced adhesion to ECM or fibronectin. ECM from CCN1 knockdown cells was a poor substrate for adhesion, as compared to ECM from control cells. These results suggest that CCN1 contributes to LPA responses in the tumor microenvironment.

However, the therapeutic potential of targeting survivin in a fully established fibrotic liver needs to be investigated. In this study, we chemically induced hepatic fibrosis in mice using carbon tetrachloride (CCl4) for 6 weeks, which was followed by treatment with a survivin suppressant (YM155).

Alternatively, activated M2 macrophage subtype induced survivin expression in HSCs through the TGF-β-TGF-β receptor-I/II signaling. Inhibition of survivin in HSCs promoted cell cycle arrest and senescence, which eventually suppressed their activation. In vivo, YM155 treatment increased the expression of cell senescence makers in HSCs around fibrotic septa such as p53, p21, and <i>β</i>-galactosidase.

Doxorubicin (adriamycin) is an injectable DNA intercalating drug that halts cancer cell growth by inhibiting topoisomerase 2, but its long-term effectiveness is compromised by onset of resistance. This study demonstrates that expression of the PAR2 gene in human colon adenocarcinoma tissue samples was the highest among 32 different cancer types (n = 10,989), and higher in colon adenocarcinoma tissues (n = 331) than normal colon tissues (n = 308), revealing an association between PAR2 expression and human colon cancer. HT29 cells are a human colorectal adenocarcinoma cell line that is sensitive to the chemotherapeutic drug doxorubicin and also expresses PAR2. We find that PAR2 activation in HT29 cells, either by an endogenous protease agonist (trypsin) or an exogenous peptide agonist (2f-LIGRL-NH<sub>2</sub>), significantly reduces doxorubicin-induced cell death, reactive oxygen species production, caspase 3/7 activity and cleavage of caspase-8 and caspase-3. Moreover, PAR2-mediated MEK1/2-ERK1/2 pathway induced by 2f-LIGRL-NH<sub>2</sub> leads to upregulated anti-apoptotic MCL-1 and Bcl-xL proteins that promote cellular survival. These findings suggest that activation of PAR2 compromises efficacy of doxorubicin in colon cancer. Further support for this conclusion came from experiments with human colon cancer HT29 cells, either with the PAR2 gene deleted or in the presence of a pharmacological antagonist of PAR2, which showed full restoration of all doxorubicin-mediated effects. Together, these findings reveal a strong link between PAR2 activation and signalling in human colon cancer cells and increased survival against doxorubicin-induced cell death. They support PAR2 antagonism as a possible new strategy for enhancing doxorubicin therapy.</p>\u0000 </div>","PeriodicalId":15226,"journal":{"name":"Journal of Cell Communication and Signaling","volume":"17 4","pages":"1293-1307"},"PeriodicalIF":3.6,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10713943/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138291007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
