Lymphoma is a cancer of the lymphoid cells that originated in matured B or T cells. The bioactive natural compounds can efficiently treat this disease with lesser side effects. Thus, in this study, a natural stilbene B10 (3-methoxy 5-hydroxy stilbene) isolated from Cajanus cajan (Pigeon Pea) was screened for its anti-proliferative efficacy against 13 cancer cell lines. B10 showed a potential effect on the human lymphoma (Raji) cells. Cytotoxicity analysis of B10 has revealed IC concentrations in Raji cells at low doses (18 µM) than other cancer cell lines. The B10 could significantly cause dose and time-dependent inhibition in the proliferation of Raji cells triggering intrinsic apoptosis and S/G phase cellular arrest. There was an increased expression of phospho-γ-H2A.X and decreased expression of cyclin D1, causing DNA damage and cell cycle arrest, post- B10 treatments. The mitochondrial membrane potential (MMP) variations observed after B10 treatment led to changes in Bax/Bcl-2 ratio, cytochrome C release, and enhanced expression of cleaved caspase3, 9, PARP-1, and APAF-1. The B10 inhibited the proliferation of Raji cells by significantly downregulating the expression of KRAS, BTK, MDM2, P-JAK2, P-STAT3, PI3K, HDAC1/2, SIRT7, and EP300. The treatment upregulated the tumor suppressor genes PEBP1 and SAP18. Thus, the study could reveal the selective inhibitory effects of B10 on lymphoma, suggesting it as a probable innovative chemotherapeutic agent.
