Mutations produced by transmutation of phosphorus-32 to sulfur-32 within Drosophila DNA.

Stability of Drosophila chromosomes to radioactive decay of incorporated phosphorus-32.

HOSPHORUS-32 incorporated into DNA in Drosophila melanogaster germ cells offers a method of analyzing the genetic effects-if any--of a known number of transmutations and associated energies of recoil in the DNA, provided the genetic effect of the “long range” and therefore nonspecific beta radiation can be eliminated or accurately determined. In multicellular organisms the separation of the mut...

Phosphorus-32, a Clinically Available Drug, Inhibits Cancer Growth by Inducing DNA Double-Strand Breakage

Radioisotopes that emit electrons (beta particles), such as radioiodine, can effectively kill target cells, including cancer cells. Aqueous 32P[PO4] is a pure beta-emitter that has been used for several decades to treat non-malignant human myeloproliferative diseases. 32P[PO4] was directly compared to a more powerful pure beta-emitter, the clinically important 90Y isotope. In vitro, 32P[PO4] wa...

Vitamin D and Endochondral Ossification in the Rat as Indicated by the Use of Sulfur-35 and Phosphorus-32

The concentration of inorganic sulfate-sulfur in the serum of vitamin D-deficient rats, 2.6 to 3.5 mg. per cent, was found to be higher than that in the serum of normal rats of the same age, 2.0 mg. per cent. No change was observed following the administration of 25 gamma of vitamin D(2). In accord with the results of others, it was found that a definitely increased deposition of phosphorus in ...
