The hallmark of pancreatic ductal adenocarcinoma (PDAC) is abundant desmoplasia, which is orchestrated by pancreatic stellate cells (PSCs) and accounts for the majority of the stroma surrounding the tumour.Healthy PSCs are quiescent, but upon activation during disease progression, they adopt a myofibroblast-contractile phenotype and secrete and concomitantly reorganise the stiff extracellular matrix (ECM).(c) Fibronectin/LTBP-1 co-localisation analysis of control PSCs and ATRA treatment group cultured in the presence of excess fibronectin revealed a significant decrease in ATRA treatment when compared to control.Representative for 3 independent experiments; *p To further dissect whether LTBP-1 fibril formation is dependent on the presence of fibrillar fibronectin, fibronectin expression was knocked down by si RNA (50 n M) in control PSCs prior to culturing the cells for 48 hours on LTBP-1 rich ECM.This site stores nothing other than an automatically generated session ID in the cookie; no other information is captured.In general, only the information that you provide, or the choices you make while visiting a web site, can be stored in a cookie.For example, the site cannot determine your email name unless you choose to type it.Allowing a website to create a cookie does not give that or any other site access to the rest of your computer, and only the site that created the cookie can read it.
PDAC is characterised by an abundant desmoplastic response, defined as sustained proliferation and concurrent deposition of altered cancer-supporting ECM by stromal cells, leading to a stiff tumour-favouring microenvironment.Furthermore, LTBP-1 and fibronectin co-localisation was significantly reduced with ATRA treatment compared to vehicle treated PSCs (p Preparation of LTBP-1 rich ECM and LTBP-1/fibronectin co-localisation by PSCs (a) HEK-293 were seeded on coverslips and transfected with LTBP-EGFP.After 7 days of culture, HEK-293 cells were removed with DOC buffer and replaced by PSCs which secrete fibronectin (FN) into the HEK-293-generated ECM.ATRA has also been shown to promote cell compliance in acute promyelocytic leukemia via cytoskeletal remodelling.
Therefore, we hypothesized that the ability of ATRA to promote cell compliance and to reduce ECM remodelling could interfere with the priming and activation TGF-β by PSCs.(c) Quantification of colocalisation and fibre thickness.
