Small interfering RNA (siRNA) is routinely used as a biological tool to silence
specific genes, and is under active investigation in cancer treatment strategies.
Noninvasive magnetic resonance spectroscopy (MRS) provides the ability to assess
the functional effects of siRNA-mediated gene silencing in cultured cancer cells,
and following nanoparticle-based delivery in tumors in vivo. Here we describe the
use of siRNA to downregulate choline kinase, a critical enzyme in choline
phospholipid metabolism of cancer cells and tumors, and the use of (1)H MRS of
cells and (1)H magnetic resonance spectroscopic imaging (MRSI) of tumors to
assess the efficacy of the downregulation.
