  1. Magnesium decreases R-loop accumulation in human cells (ATXN2-deficient cells).

    “human cells deficient in ATXN2, the human ortholog of Pbp1, exhibit nuclear R-loop accumulations repressible by Mg2+”

  2. Magnesium decreases R-loop accumulation in yeast cells (Pbp1-deficient cells).

    “magnesium ions guided by cell membrane Mg2+ transporters Alr1/2 act via Mg2+-sensitive R-loop suppressors Rnh1/201 and Pif1 to restore R-loop suppression, ribosomal DNA stability and cellular lifespan.”

1 study
  1. AAV5-mediated SIRT5 gene therapy decreases R-loop accumulation in mouse cells (oxidative stress or Prmt6 loss).

    “AAV5-mediated Sirt5 overexpression restored HADHA expression, attenuated R-loop accumulation and senescence phenotypes induced by oxidative stress or Prmt6 loss, and alleviated trabecular bone loss.”

Loss of a regulatory protein worsened bone loss in mice

Experiments found that mice lacking SIRT5, a protein that modifies other proteins, had poorer bone formation and more severe bone loss than normal mice.Experiments found that mice lacking SIRT5, a protein that modifies other proteins, had poorer bone formation and more severe bone loss than normal mice.
