Since different muscle fiber types have different functional and metabolic properties [20], systematic difference in fiber-type composition between human and other primate species could explain our observations of extensive metabolic differences and reduced human muscular strength. To examine the metabolic differences among tissues further, we sorted 9,603 metabolite peaks that showed significant concentration differences among the tissues into 13 metabolite clusters using nonsupervised hierarchical clustering (Figure 2a, Figure S4). The upper panel is based on 1,535 annotated metabolite peaks, and the lower panel on 9,155 metabolite peaks that could not be annotated. The modules (metabolite groups) are shown in Figure S12. The results suggest that, while humans are characterized by superior cognition, their muscular performance might be markedly inferior to that of chimpanzees and macaque monkeys. Each aliquot was concentrated to complete dryness in a speed vacuum centrifuge at room temperature. CAS Key Laboratory of Computational Biology, CAS-MPG Partner Institute for Computational Biology, Shanghai, China, We detect mRNA expression of hundreds of putative myokines that may . The plot is organized as in Figure S10, the metabolite groups are listed in Table S15. The coloring of the profiles corresponds to the coloring in Figure 2a. Eventually, Fred was found guilty but . The filtering resulted in 3,201 peaks in this dataset, representing 9% of the initial peak set. Accelerated evolution of the human brain and muscle metabolomes . Neuroplasticity is the brain's ability to change and adapt due to experience. This amazing video follows the lives of two extraordinary humans who suffer from rare muscular diseases and it describes the anatomy and physiology of the muscular system and what happens when this system doesn't work like it should. Ms. GWEN . Peaks showing concentration differences in the top or bottom 5% quintile of all peak differences between postmortem samples and control samples were excluded from further analyses in the respective tissue. Furthermore, in 61 of the 100 pathways, the metabolites and enzymes that showed consistent species-specific profiles were directly linked, while only 12 pathways would be expected by chance (permutation p<0.01). (a) Functional units of KEGG pathways containing significant excesses of metabolites with human-specific concentration profiles in PFC and skeletal muscle. No, Is the Subject Area "Primates" applicable to this article? Small molecules present in the tissue samples were assayed using the following methodologies: (i) gas chromatography-mass spectrometry (GC-MS), (ii) positive mode liquid chromatography-mass spectrometry ([+]LC-MS), and (iii) negative mode liquid chromatography-mass spectrometry ([]LC-MS). Morbi eu nulla vehicula, sagittis tortor id, fermentum nunc. As all human and most chimpanzee samples were not collected immediately after death, we removed from further analysis 636 peaks with concentrations affected by postmortem delay (Table S3). Incredible Human Machine Video Worksheet Directions: Answer the following questions as you watch the movie. This documentary investigates the world of muscles, how they work, the science behind muscles, and much more, taking you on a journey inside the body of two remarkable people. The Amazing Human Body DVD. In humans, muscle tissue is known to have variable fiber-type composition, reflecting differences in individuals' physiology and physical activity [19]. Neck extension is the opposite of flexion and is accomplished by many of the same muscles that are used for other neck movements, including the splenius cervicis, splenius capitis, iliocostalis, longissimus, and spinalis muscles. With hundreds of free documentaries published and categorised every month, there's something for every taste. 3. The ratios are based on metabolite peaks from all datasets. The silhouette value reflects the quality of clustering favoring well-separated compact clusters. primary visual cortex. Pathways not containing enzymes with matching expression profile are indicated by lighter shades of red and blue. Daniel Lieberman's Edge Bio Page. Comparison of gene expression among three primate species was based on the genome mapping reported by the liftOver tool. In order to identify metabolite peaks with concentration levels altered by changes in diet, stress, and physical activity in macaques, we performed a t-test on the tissue samples from condition 1 (n=6) or condition 2 (n=6) macaque individuals and the control tissue samples of all macaque individuals with unaltered environmental conditions (n=17) in each tissue. Cameras follow a 12-year-old with a bulging vascular malformation caused by abnormal blood vessels as he undergoes a risky procedure to have it diminished. Documentaries, lectures, and movies. We used metabolite annotation from both HMDB and KEGG databases to link the metabolites to metabolic pathways. extraordinary humans muscles transcript. No, Is the Subject Area "Chimpanzees" applicable to this article? Only 3 left in stock - order soon. a) fecal impaction b) suicide c) depression d) hip fractures ACE. Metabolites were extracted from the frozen tissue powder by a methanol: methyl-tert-butyl-ether (13 [v/v]) extraction according to Giavalisco et al. View Copy of Extraordinary Humans_ Muscles.docx from ENGLISH AP at Ardrey Kell High. We thank the personnel of the Suzhou Animal Research Center and particularly Changgen Lian, Su Jin, and Bijia Jiang for help with macaque strength experiments; the personnel of the Shanghai Weiyu junior middle school and particularly Dongping Wang for help with human teenager strength experiments; Guo Song for help in climber recruitment; Jing Jin, He Zhisong, Hindrike Bammann, Hu Haiyang, Li Qian, Yunxian Huang, and Yoann Portugal for technical help in the muscle strength experiments; Mikhail Gelfand, Michael Lachmann, and Mehmet Somel for helpful discussions; and Jerome Boyd-Kirkup for help in manuscript preparation. The samples were incubated for 10 min at 4C on an orbital shaker. Human individuals included 29 adults 1734 years of age with a wide span of body mass between 42 and 127 kg (mean 64 kg15 kg SD). The linear regression between metabolite concentration divergence and phylogenetic distances represented by the dashed line was calculated based on the proportions of metabolite peaks with significant concentration divergence on the corresponding lineage for the three nonhuman species (represented by circles). Human-specific metabolic changes in the PFC included two such units: (i) translational metabolism (valine, leucine, and isoleucine degradation, selenocompound metabolism, aminoacyl-tRNA biosynthesis); and (ii) neurotransmitter signaling (dopaminergic synapse, cocaine and amphetamine addiction) (Figure 4a, Table S14, Figure S10). People with genetic bone disorders are profiled, including a 9-year-old with brittle bone disease, and a 28-year-old with fibrodysplasia ossificans progressiva (FOP), which turns muscles into bone. He is able to draw entire cities from memory after seeing them only once. Commons Attribution 4.0 International License. But how do our muscles work? Organization of the Table is analogous to Table S14. The engagement ring hasnt always been what it is today. On the molecular level, such experiments could involve isolation of individual muscle types or functional groups and testing of their contractile properties. The colors within the bars represent proportions of metabolite concentration changes on the corresponding lineages. Sequencing libraries were prepared using the TruSeq RNA-seq Sample Preparation Kit (Illumina) according to the manufacturer's instructions. The normalization was performed on groups of samples belonging to the same tissue, an approach that was selected out of several other methods [25] according to normalization-quality measures of peak variation within samples of the same tissue and species. For comparison, overlap with metabolites showing chimpanzee-specific concentration profiles is also shown. Thanks for watching, please subscribe for more videos.NGC investigates the science of muscle by taking us on a journey inside the bodies of two remarkable hu. The plot is based on the 4,698 metabolite peaks that showed significant concentration differences in any tissue in the three primate species (t-test, permutation p<0.01). The Table lists: pathway names and IDs, pathway p-Values, numbers of pathway metabolites showing human-specific concentration profiles, numbers of enzymes showing human-specific expression profiles, numbers of pairs of directly linked enzymes and metabolites with human-specific and concentration level profiles, as well as p-Values indicating probabilities of finding equal or greater numbers of enzymes or linked enzymes in metabolites sets randomly sampled 100 times. This talk was presented to a local . (c) Heat map of relative metabolite concentration levels across three primate species. The shape of the symbols represents the individual's sex: circles: females, diamonds: males. After 30 seconds of vortexing and 15 min of centrifugation at 4C, 300 l, the aqueous phase was transferred to an ultrafiltration tube (Millipore). Get ready for liftoff: Today's special edition of CNN 10 is taking you up, up and away as we focus on space. Sep 29, 2019 - What an evening ladies and gentlemen, ladles and jelly spoons, the same. Asterisks indicate the significance of muscle strength difference between humans and the other two species (Wilcoxon test, p<0.001). In addition, we tested 15 teenagers (1314 years, seven females, eight males, body mass 4369 kg, mean 53 kg7 kg) with ages corresponding to the ages of the tested macaques and some of the tested chimpanzees. PK was supported by the Foreign Expert 1000 Talents Plan program; KB was supported by a Chinese Academy of Sciences fellowship (2011Y1SB06). For reconstruction of the mouse and human junctions, we additionally used mouse genome annotation and homology information. tower hill insurance net worth. In the quantitative part of our analysis, we used the entire set of unannotated peaks satisfying the above quality criteria. Effect of postmortem delay on metabolite concentrations. Samples are ordered along the X-axis according to tissue as indicated below the axis. (b) Relationship between species-specific metabolite concentration divergence in each tissue and the corresponding phylogenetic distances in million years (MY). The red part of each bar shows pathways with significant overrepresentation of enzymes with matching tissue-specific expression profiles. signs of insecure coworkers grafana dashboard json environment variables. List of samples used to assess effects of postmortem delay, diet, and physical activity on metabolite concentrations.
