Membrane-bound TNF mediates microtubule-targeting chemotherapeutics-induced cancer cytolysis via juxtacrine inter-cancer-cell death signaling

Abstract: Microtubule-targeting agents (MTAs) are a class of most widely used chemotherapeutics and their mechanism of action has long been assumed to be mitotic arrest of rapidly dividing tumor cells. In contrast to such notion, here we show-in many cancer cell types-MTAs function by triggering membrane TNF (memTNF)-mediated cancer-cell-to-cancer-cell killing, which differs greatly from other non-MTA cell-cycle-arresting agents. The killing is through programmed cell death (PCD), either in way of necroptosis when RIP3 … Show more

“…c-JUN is known as an important transcription factor involved in many carcinogenic processes, especially in cell cycle progression, 48 anti-apoptotic activity, 49 and cell proliferation, 50 and it serves as a downstream effector of the PI3K / AKT signal. 51 , 52 It was reported to be involved in many miRNAs’ regulation as a transcription factor, such as miR-374a 53 , 54 and miR-3188.…”

“…In turn, IL1b has a plethora of pro-cancerogenic effects [ 191 ]; however, it can also induce the anti-cancerogenic Th1 polarisation [ 192 ] and is regulated by the p73/caspase1/inflammasome axis [ 150 , 193 ]. p73-mediated caspase-1 expression is induced by TNFa that also induces a pro-cancerogenic program in SSC [ 63 ] but apoptosis in endothelial cells, respectively [ 165 , 194 , 195 , 196 ]. The TAp73-induced expression of BGN inhibits the TGFb pro-oncogenic signalling [ 122 ].…”

“…TNF directly induces apoptosis and necrosis in tumor cells ( Adjuto-Saccone et al, 2021 ). It elevates the expression of death receptors on tumor cell surfaces, binding to them to activate downstream apoptotic pathways ( Zhang et al, 2020 ). Furthermore, TNF enhances the cytotoxic activity of immune effector cells, such as macrophages and NK cells, against tumor cells ( Müller and Kontermann, 2010 ).…”
