Curiously mouse neonates and zebrafish larvae or adult are able to regenerate their hearts via cardiomyocyte de differentiation and proliferation. However a molecular mechanism of why these cardiomyocytes can re enter cell cycle is poorly understood. Here we identify a unique metabolic state that primes adult zebrafish and neonatal mouse ventricular cardiomyocytes to proliferate. Zebrafish and neonatal mouse hearts display elevated glutamine levels predisposing them to amino acid driven activation of TOR. We show that this TOR activation is required for zebrafish cardiomyocyte regeneration in vivo. post injury we observe pS6 in both the epicardium and ventricular cardiomyocytes suggesting these are amino acid primed cells necessary for regeneration. Through single cell and system wide RNA sequencing LQC proteomics and microscopy we identify dramatic metabolic and mitochondrial changes during the first week of regeneration. These data suggest that regeneration of zebrafish myocardium is driven by metabolic remodeling and reveals a unique metabolic regulator TOR primed state in which zebrafish and mammalian cardiomyocytes are regeneration competent. Overall design: We performed bulk RNA seq of zebrafish heart at embryonic/fetal day 3 adult control and 3 and 7 xxx post injury.	parent bioproject:PRJNA778001	pubmed:34988408		Young day 3 heart 1	GSM5673294		source name:Zebrafish heart\|tissue:Heart\|age:Young\|treatment:N1\|time point:N1	Young day 3 heart 1	Raw reads were aligned to Ensembl GRCz10 using Tophat version 2.0.13.

Zebrafish heart	All chemical ventricular cardiomyocyte VCM ablation were conducted on adult Zebrafish 5 mpf 12 mpf. For chemical mediated VCM ablation fish were treated with 5 mM Metronidiazole MTZ; Sigma containing 0.1% dimethyl sulfoxide DMSO or vehicle control 0.1% DMSO for 48 hours protected from light and refreshed every 24 hours. For Wnt and DKK heat shock heterozygous animals 7.5 mM MTZ was used. Following chemical treatment fish were placed back in original aquaria and hearts were collected at 0 prior to MTZ 3 7 12 and 30 xxx post injury dpi. Larval hearts 72 hpf were isolated and pooled as previously described. 6 hearts 3 males and 3 females were isolated from Adult UI 3 dpi and 7 dpi zebrafish. Each group had 2 sets of samples of 3 hearts each for the digestion process. Each set of 3 hearts were single celled as previously described. All cells per group were then pooled and sent for sequencing.	For young 3 dpf zebrafish heart samples we sequenced N=2 with about n=500 hearts pooled. For the adult heart samples we sequenced N=2 hearts at UI 3 and 7 dpi with each n=4 6 pooled hearts. A negative binomial test was performed to determine significantly changed genes. Around 20 000 genes were found. RNA was isolated from young 3 dpf adult 6 mpf and regenerating 3 and 7 dpi zebrafish hearts as per manufacturers’ protocol TRIzol ThermoFisher. The libraries were sequenced together on an Illumina HiSeq 4000 Illumina Inc. San Diego CA.	Wild type AB; Zebrafish International Resource Center Eugene OR USA hsWnt8:GFP [Tghsp70l:Wnt8a GFPw34] and hsDKK1:GFP [Tghsp70l:DKK1b GFPw32] and vmhc:mCherry NTR [Tgvmhc:mCherry Eco.NfsB] were used and maintained using standard procedures in accordance with the Institutional Animal Care and Use Committee approved protocols IACUC 2057 01 & 4364 02. Reverse osmosis system water is used and the water chemistry was adjusted to a temperature of 27.5°C pH of 7.5 conductivity of 800 µS hardness of 140 ppm alkalinity of 35 ppm dissolved oxygen content of 7.8 mg/L and a total gas pressure of 101%. The average nitrate level is 55 ppm the average nitrite level is 0.05 ppm and the average ammonium level is 0.01 ppm. Larval feed starting at 5 dpf dpf is a rotifer polyculture supplemented with the Zeigler larval diet at 12 dpf live artemia is added to the diet and at 60 dpf 90 dpf the fish are started on the Zeigler adult diet supplemented with live artemia once per day. The health status of the colony showed low presence of pseudoloma neurophilia and an extremely low presence of mycobacterium spp. with no major clinical or subclinical findings of significance.	tissue:Heart\|age:Young\|treatment:N1\|time point:N1	GSM5673294	GSM5673294: Young day 3 heart 1; Danio rerio; RNA Seq	GSM5673294		1	For young 3 dpf zebrafish heart samples we sequenced N=2 with about n=500 hearts pooled.
