My research reveals a new way to treat certain colorectal cancers, focusing on a genetic change where the APC gene, a key cancer protector, is lost. This loss also affects a nearby gene, SRP19, making cancer cells especially vulnerable to any further suppression of this gene. By targeting SRP19, I found a way to disrupt the protein secretion of those cancer cells, causing stress and killing them. Excitingly, a low-dose treatment with Arsenic-Trioxide could exploit this weakness, offering a new strategy to fight these hard-to-treat cancers. This finding could lead to more effective therapies for cancers harboring APC loss.
