Project description:HepG2/C3A cells cultured for 42 h in complete or leucine-devoid medium Experiment Overall Design: Total of 6 Samples (Leu vs noLeu)
Project description:First experiment: Cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM methionine + 0.1 mM cysteine (complete) or supplemented only with 0.1 mM methionine (cysteine-free). Cells were cultured in either medium for 42 h (Long + Cys; Long -Cys) or in cysteine-free medium for 36 h followed by 6 h in complete medium (Short +Cys); Second experiment: C3A/HepG2 cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM Met and 0.1 mM Cys (complete) or supplemented only with 0.1 mM Met (cysteine-devoid). Cells were cultured in complete medium for 42 h (Long +Cys) or in complete medium for 36 h followed by cysteine-devoid medium for 6 h (Short -Cys). Experiment Overall Design: First experiment: Three plates of cells were cultured under each condition. Cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM methionine + 0.1 mM cysteine (complete) or supplemented only with 0.1 mM methionine (cysteine-free). Cells were cultured in either medium for 42 h (Long + Cys; Long -Cys) or in cysteine-free medium for 36 h followed by 6 h in complete medium (Short +Cys). Experiment Overall Design: Second experiment: C3A/HepG2 cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM Met and 0.1 mM Cys (complete) or supplemented only with 0.1 mM Met (cysteine-devoid). Cells were cultured in complete medium for 42 h (Long +Cys) or in complete medium for 36 h followed by cysteine-devoid medium for 6 h (Short -Cys).

Project description:SurePrint G3 Human Gene Expression 8x60k oligonucleotide microarrays (Design ID: 039494,Agilent) were used to characterize gene expression profiles of HepG2/C3A cells exposed to HBCD (hexabromocyclododecane) or DMBA (dimethylbenzanthracene) for 24 hours.
Project description:<p>Divergence in the non-targeted metabolite profilings of bovine mammary epithelial cells (BMECs) were systematically captured with regard to 10 individual essential amino acid (EAA) availability. BMECs cultured in 6-well plates were first serum-starved overnight and subsequently assigned to 1 of 12 treatment media (n = 6). DMEM-F12 medium is the positive control treatment (POS), while DMEM-F12 medium devoid of all EAA served as the negative control treatment (NEG). A total of 10 treatments were NEG individually supplemented with arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan or valine (Sigma-Aldrich, MO, USA). Individual EAA were supplemented to achieve concentrations equal to those of POS. After 6-h treatment, all cell samples were taken at the same time, frozen in liquid nitrogen and stored at -80 °C until required.</p><p><br></p><p><strong>Untargeted metabolomics</strong> is reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS7789' rel='noopener noreferrer' target='_blank'><strong>MTBLS7789</strong></a>.</p><p><strong>Targeted metabolomics</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS3956' rel='noopener noreferrer' target='_blank'><strong>MTBLS3956</strong></a>.</p>
