Food preservatives don’t preserve oral cancer

Source: bigkingken.wordpress.com Food preservatives are a common part of everyday life for those Americans who don’t go to extremes to avoid them. Twinkies will be around for thousands of years despite the dissolution of Hostess and I’m pretty sure there’s an unspoiled Big Mac somewhere that’s been hanging out for several decades. Besides grossly keeping the hamburger on the left untarnished for more than a decade, food preservatives might be an untapped resource in the fight against cancer. In short, food preservatives work by killing off any and all microbial life forms that come along to munch on the food before us humans have a chance to send it down to our bellies. Now, if these food preservatives are so effective at killing off unwanted bacteria in our food supplies, could they perhaps also be effective at killing off other unwanted life forms? This is a question being asked by a lot of medical researchers at the moment, with at least one group finding an answer in the affirmative. Recently, researchers at the University of Michigan found that the common food preservative Nisin also does an excellent job of holding off – and even shrinking – the most common and deadly form of oral cancer, squamous cell head and neck cancer (HNSCC). HNSCC is a particularly nasty form of cancer, seeing as it accounts for more than 90 percent of oral cancers yet hasn’t had its mortality rates improved in the past several decades. On the other side, [...]

Food preservative may halt tumor growth

Source: www.foodproductdesign.com The common food preservative nisin may stop or slow squamous cell head and neck cancers, according to a new study published in the journal Cancer Medicine. The findings may accelerate new cancer therapies since the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO) approved nisin as safe for human consumption decades ago. Oral cancer is a leading cause of death worldwide, and oral squamous cell carcinoma accounts for more than 90% of oral cancers. However, survival rates for oral cancer haven't improved in decades, according to the study. Yvonne Kapila, the study's principal investigator and professor at the University of Michigan School of Dentistry, said antibacterial agents like nisin alter cell properties in bacteria to render it harmless. However, it's only recently that scientists began looking to antibacterial agents like nisin to see if they altered properties in other types of cells, such as cancer cells or cells in tumors. "The poor 5-year survival rates for oral cancer underscore the need to find new therapies for oral cancer," she said. "The use of small antibacterial agents, like nisin, to treat cancer is a new approach that holds great promise. Nisin is a perfect example of this potential because it has been used safely in humans for many years, and now the laboratory studies support its anti-tumor potential." The study, which looked at the use of antimicrobials to fight cancerous tumors, suggests nisin, in part, slows cell proliferation or causes cell death through the activation [...]
