Inflammation-Related Immune-Modulatory SLURP1 Prevents the Proliferation of Human Colon Cancer Cells, and Its Delivery by <i>Salmonella</i> Demonstrates Cross-Species Efficacy against Murine Colon Cancer
This study investigates the anticancer properties of the α7-nAChR antagonist SLURP1 with a specific focus on its effect as an inflammation modulator on human colorectal cancer cell lines Caco2, Colo320DM, and H508 cells. The investigation includes the evaluation of cell cycle arrest, cell migration...

| 520 | |a This study investigates the anticancer properties of the α7-nAChR antagonist SLURP1 with a specific focus on its effect as an inflammation modulator on human colorectal cancer cell lines Caco2, Colo320DM, and H508 cells. The investigation includes the evaluation of cell cycle arrest, cell migration arrest, endogenous expression of SLURP1 and related proteins, calcium influx, and inflammatory responses. The results demonstrate that SLURP1 not only inhibits cell proliferation but also has the potential to arrest the cell cycle at the G1/S interface. The impact of SLURP1 on cell cycle regulation varied among cell lines, with H508 cells displaying the strongest response to exogenous SLURP1. Additionally, SLURP1 affects the nuclear factor kappa B expression and effectively reverses inflammatory responses elicited by purified lipopolysaccharides in H508 and Caco2 cells. This study further confirmed the expression of human SLURP1 by <i>Salmonella,</i> under <i>Ptrc</i> promoter, through Western blot analysis. Moreover, <i>Salmonella</i> secreting SLURP1 revealed a significant tumor regression in a mouse CT26 tumor model, suggesting the cross-species anticancer potential of human SLURP1. However, further investigations are required to fully understand the mechanisms underlying SLURP1's ability to prevent cancer proliferation and its protective function in humans. | ||
