Vitamin B12 deficiency is a risk factor for bone disorders via mechanisms not fully understood. In this study, an increase in serum inorganic phosphorus (Pi) concentrations was associated with a vitamin B12 deficiency. Napi2a, a renal cotransporter for Pi reabsorption, accumulated on plasma membranes in a vitamin B12 deficiency suggests that vitamin B12 plays an important role in Pi homeostasis.
Numerous epidemiological surveys have shown that consuming coffee can prevent cancer development. Caffeine and chlorogenic acid are the most well known constituents which are included in coffee and prove to have an positive effect to prevent cancer. Although these constituents are known to directly act on anti cancer machineries, such as anti-oxidant effect. There are also studies showing that benefit of functional food is exhibited by metabolic changes. Therefore, we may anticipate that changing metabolic pathways may occur during coffee intake and further expect lowering the cancer risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
