Treatment:

Treatment ID:	TR002368
Treatment Summary:	Dihydroepiandrosterone (BioVision, 2172) was resuspended to a 1M stock in DMSO and g6pdi (Cayman Chemical Co., 31484) to a 10mM stock in DMSO. Tadples were reared with 0.1% DMSO, 25µM DHEA or 10µM g6pdi diluted in 1/9x MR until collection after a 24 treatment. For 2DG injections, wild type tadpoles at stage 41 were anesthetized with MS-222 and moved from culture dish to a thickly coasted agarose dish in one drop of media. Excess media was removed. Using a microinjector, a pulled needle containing vMO and labeled dextran tracer was inserted into the ventral tail vein and 2×2 nL of 1M 2DG (Sigma, D8375) were injected. Controls for 2DG experiments were injected with equal volumes of tracer. Embryos were returned to fresh media and screened for tracer fluorescence in the bloodstream. Injected animals were kept in 1/9x MR until collection after a 24 treatment.
