In Vitro Oral Cancer Sensitive to Omega 3 Fatty Acids

Researchers out of London (Queen Mary, University of London) report that omega-3 fatty acids can inhibit growth and induce cell death of squamous-cell carcinoma, IN VITRO. (Newspapers tend to skip over that part) http://carcin.oxfordjournals.org/content/early/2013/07/24/carcin.bgt257.abstract Omega-3 polyunsaturated fatty acids selectively inhibit growth in neoplastic oral keratinocytes by differentially activating ERK1/2 The long chain omega-3 polyunsaturated fatty…

Bacteria, Ancient Teeth and Modern Teeth

I had previously noted research indicating that modern diet has changed the bacterial profile of our guts. This new paper looks at the oral microbiome at different time periods and how that has affected dental health. Like the previous paper it finds a marked change in the microbiomes between ancient and modern samples specifically tied…

Spitting Image

Even our spit is unique. OPEN ACCESS Genome Res. 2012. 22: 2146-2152 Nurture trumps nature in a longitudinal survey of salivary bacterial communities in twins from early adolescence to early adulthood Abstract Variation in the composition of the human oral microbiome in health and disease has been observed. We have characterized inter- and intra-individual variation…
