As a young assistant professor at the University of Washington in the late 1980s, Randall Moon stole into his quiet lab during a holiday break to run one experiment. He had a hunch that the INT-1 gene played a crucial role in development. It turned out he was right: In that one experiment he discovered a critical signaling pathway and the direction of his career for the next 15 years, which he writes a

Skinny fat, really? In "The skinny fat ," 1 Bruce Spiegelman tells us he is working with the Broad Institute to screen every FDA-approved drug for possible effects on a "brown-fat molecule," PRDM16, reasoning that drugs that act on this molecule might also trigger weight loss. Wouldn't it be smart to determine whether any of these FDA-approved drugs are associated with signifi

By Randall MoonRelated Articles 1 and the experiments were quickly repeated by many people in the field, either out of a sense of disbelief or just because they were so easy and exciting to do. Today INT-1 is called WNT-1. Researchers realized that INT-1 and the Wingless gene in fruit flies were the same, so they combined the

Use spike-in controls for absolute quantitation. For most biological applications, relative quantitation should suffice. Sometimes, though, absolute numbers matter. The solution: spike-in controls. Add a known quantity of an isotopically labeled form of the desired peptide (or close surrogate), and use its abundance to correlate peak height with molecular abundance. This peptide will behave identically with the peptides in your samples during sample
