Transforming growth factor-β in tumour development

Abstract: Transforming growth factor-β (TGFβ) is a ubiquitous cytokine essential for embryonic development and postnatal tissue homeostasis. TGFβ signalling regulates several biological processes including cell growth, proliferation, apoptosis, immune function, and tissue repair following injury. Aberrant TGFβ signalling has been implicated in tumour progression and metastasis. Tumour cells, in conjunction with their microenvironment, may augment tumourigenesis using TGFβ to induce epithelial-mesenchymal transition, ang… Show more

“…According to previous data, TGF-β is a known inducer of the EMT program [ 20 , 40 ]. Corroborating those findings, in our experimental model, the incubation of A549 cell line for 48 h incubation with this growth factor induced an increase in the percentage of snail + cells, from 19.85 ± 3.78 (mean ± SEM) in the control to 36.54 ± 6, 91 in the presence of TGF-β ( Figure 2 A).…”

“…The production of the growth factor TGF-β by the tumor microenvironment is one of the components capable of inducing EMT [ 20 ] via activation of several transcription factors that orchestrate the process: snail [ 21 ], slug [ 22 ], zeb1 [ 23 ] and twist-1 [ 24 ]. The reduction in the expression of E-cadherin, a calcium-dependent cell-cell adhesion protein expressed in epithelial cells, is very well known during EMT, being regulated by the aforementioned transcription factors, especially snail [ 25 , 26 , 27 ].…”

“…Tsukada et al reported that PTX signi cantly suppressed transforming growth factor β (TGF-β)/Smad signaling in human peritoneal cells by inhibiting Smad2 phosphorylation and reducing stromal brosis in vitro [29]. The TGF-β/Smad pathway plays an important role in epithelialmesenchymal transition (EMT) [32,33], which is related to cancer progression and cancer-associated tissue brosis. This is thought to be a dual effect of paclitaxel, suppressing TGF-β and subsequently inhibiting cancer cell progression as a direct effect.…”

“…In this regard, the treatment with T. cruzi antigens was associated with a decrease in splenic TGF-β levels, suggesting an attenuation of a regulatory immune response. In fact, TGF-β favours tumourigenesis, metastasis, angiogenesis, autophagy and immune suppression and can suppress antigen-presenting function of macrophages and dendritic cells [ 32 ]. Last, it would be worth exploring whether the immune response induced by the parasite antigens eliminates tumours, by rechallenging protected mice with tumour cells.…”
