Researchers Possibly Identify Reasons Behind Higher Occurrence of Colorectal Cancer in Young Adults
Readyto dive into some gut-wrenching news? It seems our friendly gut bacteria might not be so friendly after all. A recent study published in Nature reveals that a harmful toxin produced by certain strains of E. coli can trigger early onset colorectal cancer.
Lead by researchers at the University of California, San Diego, this study highlights a connection between exposure to this toxin, known as colibactin, and colorectal cancers that occur in young adults. If confirmed as causative, this finding could help explain the recent mysterious rise in early onset colorectal cancer rates.
Colorectal cancer ranks as the fourth most common cancer, with approximately 150,000 Americans diagnosed each year. It's also the second leading cause of death by cancer, claiming around 50,000 lives annually. Keep in mind that the incidence and death rate of colorectal cancer has been steadily decreasing over time, but the decline isn't equally distributed, as the incidence of colorectal cancer has been on the rise in young and middle-aged adults.
In fact, between 2012 and 2021, colorectal cancer rates among people under 50 have grown by 2.4% per year. The researchers of this new study weren't specifically setting out to decipher this mystery, but their findings add another suspect to the mix.
They weren't specifically looking to unravel the reason behind these young adult cancers; instead, their main interest was to understand why some parts of the world have higher colorectal cancer rates than others. To do so, they analyzed the genetic signature of colorectal cancers from nearly 1,000 people across the globe. They found colibactin-related mutations in the samples, and to their surprise, these mutations were about three times more common in the early onset cancers they studied compared to late onset cancers.
Furthermore, molecular evidence shows that these colibactin-related mutations tend to occur early in a tumor's development, suggesting they play a crucial role in fueling these cancers. While more research is needed to confirm the causative connection, these findings do provide fertile ground for future research and could potentially lead to interventions that slow or reverse the rise in early onset colorectal cancer.
In their attempt to combat this toxin, the researchers are already hoping to study whether probiotics might be able to eliminate these more harmful E. coli strains, and they're trying to develop early detection tests that can screen for colibactin-related mutations. However, all this work is contingent on further funding, and the researchers are quick to note that the U.S. government under President Donald Trump has aggressively limited funding from the National Institutes of Health in recent months—the same type of funding that might go to vital cancer research like theirs.
In a nutshell, the bacterial toxin colibactin contributes to early-onset colorectal cancer by causing specific mutational damage in the DNA of colonic cells, particularly during the critical early stages of life. This mutagenic effect primarily targets the adenomatous polyposis coli (APC) gene, which is a crucial tumor suppressor gene that regulates cell growth and division. If these findings hold up, prevention strategies like detecting and targeting colibactin-producing bacteria in at-risk populations might become crucial for mitigating the rising trend of early onset colorectal cancer.
