Vitamin D modulates intestinal epithelial cell function to enhance antitumor microbes
The gut microbiome has been shown to modulate the response of cancer patients to therapy, but precisely how microbiota affect anticancer immunity is still being elucidated. Giampazolias et al. report that vitamin D bioavailability in mice influences the composition of the gut microbiome (see the Perspective by Franco and McCoy). After dietary manipulation, vitamin D levels were observed to affect gut bacteria, which in turn improved cancer immunotherapy and antitumor immunity. In humans, low vitamin D levels were correlated with tumor development, and gene signatures of vitamin D activity were associated with improved patient responses to immunotherapy. These findings highlight the connection between vitamin D and the immune system through gut bacteria and may have applications for improving cancer therapies.
Lake Tanganyika contains one of the most impressive adaptive radiations, with about 250 species of cichlid occupying a variety of niches. Much research has focused on understanding the drivers of this and other adaptive radiations. Trembo et al. looked in depth at 57 of these cichlid species with regard to their behavior, ecomorphology, and genomics. They found that one behavior in particular, a tendency to explore, was related to niche adaptation, and they identified a regulatory gene that is highly associated with this behavior. These findings suggest the existence of an adaptive syndrome driven in part by a tendency to explore what is new.
