This study tests the feasibility of chronically elevating skeletal muscle NAD+ in mice and investigates the putative effects on mitochondrial respiratory capacity, insulin sensitivity, and gene expression. The metabolic effects of NR and PT treatment were modest. We conclude that the chronic elevation of skeletal muscle NAD+ by the intravenous injection of NR is possible but does not affect muscle respiratory capacity or insulin sensitivity in either sedentary or physically active mice. Our data have implications for NAD+ precursor supplementation regimens.

Many Mediocre Cancer Therapies Become Much Better When More Targeted to Cancerous Tissues
One of the important areas of cancer research and development that appears to receive a great deal of attention and funding, but in practice seems slow to make it from the laboratory to the clinic, is the targeting of therapeutics to cancerous cells. Reductio ad absurdum, near any of dozens of existing chemotherapeutics would do the job of completely clearing tumors, with minimal to no side-effects, if one could only find a way to delivery tiny amounts of the therapeutic to every cancer cell while avoiding every healthy cell. The inability to target treatments this effectively is exactly why cancer remains such a problem. ...
