Study Title | Untargeted lipidome changes in Chlamydomonas reinhardtii treated with small molecules containing adamantane structures |
Study Summary | A study to investigate the effect of small molecule lipid inducing compounds that leads to hyper accumulation of lipids in N replete cells of Chlamydomonas reinhardtii. These compounds were identified through a high throughput screening designed for that purpose. During that screening, we screened 43,783 compounds and identified 367 primary hits. These 367 hits were further retested using a 8-point dilution series (from 0.25 to 30 uM) and verified the activity of 250 compounds that induce the hyper lipid accumulating phenotype in algae. Once the hit compounds were identified and confirmed, we then performed extensive chemoinformatics analysis to look for common scaffolds and identified several common substructures. We then selected 15 top performing compounds from 5 diverse structural groups and tested biochemical parameters such as growth, lipid accumulating capacity, effect on photosynthetic rates, respiration rates, oxygen consumption rates, analysis of different lipid species to quantify and identify fatty acid species using GC-MS. To understand the global changes in the lipidome, 2 structurally similar compounds were selected and compared with cells grown without compounds as control for untargeted lipidome analysis. |

Treatment:
Treatment ID: | TR001415 |
Treatment Summary: | For compound treatment, cells from mid-log phase culture were harvested, washed once with fresh sterile TAP media and inoculated at starting density of 5 x 105 cells/mL. Thus for the current experiment 3 different treatment conditions were generated. Cells without compound treatment were negative control for the lipid accumulation and 2 compounds were used to generate treatment conditions. All compounds were used at a final concentration of 5 uM (this concentration was determined using a dose-response curve). For all cultures, 250 mL Erlenmeyer flasks with rubber stopper adopted to facilitate gas exchange were used and maintained in horizontal orbital shaking growing chamber (Innova 43; New Brunswick). At the end of 72h, cells were harvested, media was removed via centrifugation and biomass was stored at -80 C until lipids extraction. |
