Web14 jul. 2011 · This mechanism is also distinct from the findings in Nras G12D/+ initiated CMML, in which 2 of 5 mice up-regulated the expression of oncogenic Nras protein through UPD of the oncogenic Nras allele. 19 It is not clear what leads to the differential mechanism(s) of up-regulating oncogenic Nras signaling in myeloid cells versus T cells. Web12 apr. 2024 · Therefore, we pursued a mechanism of TNF expression in melanoma based on Sp1, Ets-1, and cJUN activity . TNF-α is known to induce its own production ( 51 ), leading to an autocrine signaling loop. These positive feedback loops are associated with bistability in biological systems ( 52 ), meaning that the system can occupy one of two …
