Overall, we can conclude that combined inhibition of IGF-1R and HIF-1 appears to result in a synergistic effect on the migration of triple-negative MDA-231 breast cancer cells, and similar results obtained in MDA-468 cells, also triple-negative, raise the hope that our findings may be extended to this hard-to-treat breast cancer subtype.
Over a certain period of time (23.5 minutes), this radioactive isotope loses a negatively charged electron, or beta particle ; this loss of a negative charge raises the positive charge of the atom by one proton, so that it is effectively transformed into the element neptunium (Np; with an atomic number of 93, one more than uranium).
