	Results	In animals receiving GSK1120212, shockwave treatment did not significantly change the percentage of Ki-67 or phospho-Erk1/2 positive cells (Figure 9B and C). These data support our findings that ischemic wound healing in shockwave treated animals is significantly enhanced by shockwave treatment and is dependent on Erk1/2 pathways.

	Results	"Planimetric analysis of the wound size area on the ischemic side of the epigastric flap was performed immediately after surgery (day 0) and on days 1, 5, and 10 after surgery (Figure 8C and D) Shockwave treatment of the ischemic side of the epigastric flap (100 pulses at 0.13 mJ/mm2) significantly decreased the wound size compared to control animals (Figure 8A). In animals receiving the Mek1/2 inhibitor GSK1120212 (0.1 mg/kg daily), wound sizes in the control and shockwave groups did not differ (Figure 8B). These results suggest that shockwave treatment exerts its beneficial effects on wound healing by induction of Erk1/2 signaling."

Cell Experiment
Cell lines	DO4, MM415, MM485, SK-MEL-2, MaMel30I and MaMel27II
Preparation method	cells were plated in 96-well plates with a density of 4000-8000 cells per well and incubated for 24 h at 37 °C with 5% C02. Then cells were incubated with increasing drug concentrations and their combinations. Cell viability was measured with the CellTiter-Glo (CTG) Luminescent Cell Viability Assay (Promega; Madison, Wisconsin, USA) according to the manufacturer’s protocol. Luminescence was measured on the SynergyHT plate reader (BioTek, Vermont, USA) using Gen5 software (Version 1.11.5). For apoptotic assays, cells were plated in 12-well plates and treated with DMSO, trametinib, metformin or combinations. After 72hrs apoptosis was assessed using the Dead Cell Apoptosis Kit with Annexin V Alexa Fluor 488 & Propidium Iodide according to the manufacturer’s protocol (Invitrogen; V13241) with the AccuriC6 Flow Cytometer using the CFlow software (Version 1.0.227.4).

Weight (kg)	0.02	0.15	1.8	0.4	0.08	10
Body Surface Area (m²)	0.007	0.025	0.15	0.05	0.02	0.5
K_m factor	3	6	12	8	5	20

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B K_m
	Animal A K_m

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the K_m factor for a mouse and then divide by the K_m factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
