Rapamycin

It's 1964, and a group of Canadian scientists had sailed across the Pacific to Easter Island in order to study the health of the isolated local population. Working below the gaze of the island's famous statues, they collected a variety of soil samples and other biological material, unaware that one of these would yield an unexpected treasure. It contained a bacterium that secreted a new antibiotic, one that proved to be a potent anti-fungal chemical. The compound was named rapamycin after the traditional name of its island source - Rapa Nui. Skip forward 35 years and rapamycin has made a…
Last time I told you about how the view of cancer switched from the perspective of metabolism to oncogenes. Today we'll see how recent developments have placed the spotlight back on metabolic pathways. I'll begin this tale with a quote from a review written by Andrew M Arshama and Thomas P Neufeld: The TOR (target of rapamycin) signaling pathway has been the subject of a 30-year-long reverse engineering project, beginning in the 1970s when the macrocyclic lactone antifungal compound rapamycin was purified from soil bacteria found on the Pacific island of Rapa Nui, famous for its moai (giant…
