Main signalling pathway mechanisms of SASP in lymphoma cellular resistance. The loss of p53 and expression of NF-κB exacerbate the paracrine activity of SASP, which promotes cytokine secretion, as well as signal transduction pathways, including mTOR/NOTCH/ERK/JAK-STAT, mediate the stem-like proliferation of lymphoma senescent cells. All of these facilitate the drug resistant characteristics of lymphoma cells. SASP, senescent-associated secretory phenotype.
