Though magnesium deficiency has beforehand been related to susceptibility to the onset of a spread of ailments, researchers affiliated with the College of South Australia and the Genome Well being Basis reported as novel their discovering correlating magnesium consumption with genomic integrity.
“The outcomes obtained within the current research point out for the primary time that low in vivo ranges of magnesium both by itself or within the presence of excessive homocysteine (Hcy) will increase DNA harm as evident by larger frequencies of micronuclei (MN) and nucleoplasmic bridges (NPBs),” they wrote.
Magnesium and homocysteine
Because the fourth most ample mineral current in human physique, magnesium is concerned as a cofactor in main metabolic and biochemical pathways throughout the cell.
“It’s related to varied capabilities throughout the physique resembling strengthening and growth of bones, nerve perform, regulating blood sugar and blood stress, protein metabolism, nucleic acid stability (DNA and RNA) and cell proliferation,” the researchers wrote.
In a previous study, members of the analysis staff reported sturdy associations between elevated homocysteine and low magnesium ranges in wholesome older adults evaluated for sleep disruption and telomere loss. Additionally they referenced findings {that a} mixture of magnesium sulfate and hypertension drug phentolamine had been more practical than magnesium sulfate alone in a group of hypertense pregnant women.
This, they famous, means that larger magnesium ranges in blood might defend the human genome from toxicity attributable to amino acid homocysteine, which is elevated when folate and vitamin B12 are poor.
Examine particulars
The research recruited 172 wholesome middle-aged adults between the ages of 35 and 65 from South Australia and measured blood ranges of magnesium, homocysteine, folate and vitamin B12, in addition to biomarkers of DNA harm—micronuclei, nucleoplasmic bridges and nuclear buds.
Magnesium and homocysteine had been discovered to be marginally larger in male individuals than in feminine individuals, and folate and B12 had been marginally decrease in males. By way of the DNA harm biomarkers, micronuclei frequency was considerably larger in females in comparison with males, however nucleoplasmic bridges and nuclear buds had been discovered to be marginally decrease in males than in females.
“In conclusion, the outcomes obtained from our research point out that optimum consumption of micronutrients resembling magnesium and B nutritional vitamins that may decrease Hcy focus is crucial for sustaining genome integrity for wholesome ageing,” the researchers wrote. “Additionally, extra analysis is required to find out the optimum dietary consumption of magnesium to attain persistently enough mobile focus of magnesium for upkeep of genomic integrity.”
They added that magnesium dietary requirement may have to contemplate the homocysteine standing of the themes and that future placebo-controlled research ought to contemplate whether or not completely different types of magnesium (e.g. magnesium citrate or magnesium sulphate) can scale back MN and NPBs.
