GNPS LCMS data from oral isolates during in vitro metabolism of sugar and lactate

ABSTRACT: Several oral bacterial species were grown anaerobically and fed either glucose or lactate in SHI medium (for method see: Edlund et al., 2013, Edlund et al, 2015 - see http://www.microbiomejournal.com/content/pdf/2049-2618-1-25.pdf & http://www.nature.com/ismej/journal/vaop/ncurrent/full/ismej201572a.html). Biofilm samples for LCMS were collected at different time points from growth wells. After growth was established in SHI medium, biofilms were washed with minimal medium and supplemented with either glucose or lactate (Veillonella species) (see Edlund et al., 2013, Edlund et al., 2015). Samples were collected both after the initial biofilm establishment in SHI medium and after the addition of the supplemented cdm medium. According to gnps network analyses and data sorting exercises: 1) ~10% of this data is reproducible; 2) several of the present masses can also be detected both in SHI and cdm medium. mzXML files for media is not uploaded here (i.e. no media subtraction can be employed using these files only).

Project description:Growth differentiation factor 11 (GDF11), also known as bone morphogenetic protein 11 (BMP11) is a member of the Growth differentiation factors (GDFs), a subfamily of proteins belonging to the transforming growth factor-beta (TGF-β) superfamily (Katoh and Katoh 2006). ). In the past 7-8 years, several high profile studies, showed that systemic restoration of GDF11 levels reverses age-related phenotypes and rejuvenated heart and skeletal muscle in aged mice (Loffredo, Steinhauser et al. 2013, Sinha, Jang et al. 2014), improves insulin sensitivity via restoring pancreatic β-cell function in diabetic mice (Li, Li et al. 2017), and increases proliferation of brain capillary endothelial cells thereby improving the vascular and neurogenic rejuvenation in the brain of aged mice (Katsimpardi, Litterman et al. 2014, Finkenzeller, Stark et al. 2015, Zhang, Guo et al. 2018). Nonetheless, the possible rejuvenation effect of GDF11 was questioned over past years by several other studies. These reports doubted the age-associated decrease of circulating GDF11 level and related phenotypes in the muscle, the heart and the brain (Egerman, Cadena et al. 2015, Rodgers and Eldridge 2015); moreover, restoration of GDF11 levels in old mice had no positive effect on heart structure or function (Smith, Zhang et al. 2015). Increase of GDF11 levels had deleterious effects on aging skeletal muscle regeneration (Egerman, Cadena et al. 2015), suggesting also that supraphysiological levels could lead to cachexia (Hammers, Merscham-Banda et al. 2017). In the field of liver diseases, GDF11 was shown to exhibit tumor suppressive properties in HCC cells (Zhang, Pan et al. 2018, Gerardo-Ramírez, Lazzarini-Lechuga et al. 2019) and to worsen hepatocellular injury and liver regeneration after liver ischemia reperfusion injury (Liu, Dong et al. 2018). From these controverted studies, it is clear that the systemic effects of GDF11 in health and disease are not yet clearly and fully delineated. The aim of the present study was to specifically characterize the role of GDF11 in lipid metabolism and in the progression of the NAFLD disease spectrum, which is currently unknown. We thus aimed at investigating the potential effect of GDF11 on lipid droplet formation in human hepatocytes. Our data strongly suggest that GDF11 supplementation exacerbates, both in presence or absence of FFA, lipid droplet accumulation in two hepatic cell models (HepG2 and Hep3B) by impinging on ALK5/SMAD2/3 dependent signaling pathway.
