Study TitleLipidomic characterization of Jurkat-derived T cell line in which the chaperonin complex CCT has been partially silenced
Study TypeUntargeted Lipidomics
Study SummaryWhen the chaperonin complex CCT is partially silenced in Jurkat-derived T cell line J77 E61, we observe changes in the production of exosomes and in their composition. Thus, to explore the bases of these alterations and find possible new mechanisms of exosome biosynthesis regulation we characterized the lipidome content in cells where the chaperonin complex CCT was partially silent (CCT) and controls (CTRL). We analyzed 5 biological replicates containing 3 × 106 cells using LC-MS in positive and negative polarity mode. For quality control, 5 QCs samples and 4 blanks were also included in the analysis (total 19 samples and 2 groups).

Project Title:Chaperonin CCT controls cell fueling by lipids and extracellular vesicle production through kinesin dynamics
Project Type:Untargeted Lipidomics
Project Summary:Cells regulate their protein content through different processes including gene transcription, protein translation, post-translational modification, secretion, degradation and recycling. The complexity of this network and its dynamic regulation remains mostly unexplored. A plethora of intracellular elements can be incorporated into multivesicular bodies (MVB) to be secreted as soluble components or extracellular vesicles (EVs). By profiling the proteome of EVs from T cells, we have found the subunits of the chaperonin CCT, involved in the correct folding of particular proteins. By limiting CCT content after siRNA silencing, cells shift the dynamics of lipid droplets, peroxisomes and the endolysosomal system, showing an accumulation of MVBs that leads to increased EV production and an altered lipid composition. Also, their metabolic profile is shifted towards a lipid-dependent metabolism. This is exerted through the dynamic regulation of microtubule-based kinesin motor.

Collection:

Collection ID:CO002264
Collection Summary:The Jurkat E6-1 cell line was obtained through the NIH AIDS Reagent Program, Division of AIDS, NIAID, NIH from Dr. A. Weiss and grown in RPMI 1640 medium (Gibco) supplemented with 10% fetal bovine serum (FBS, Invitrogen).
Sample Type:T-cells
Storage Conditions:-80℃

Treatment:

Treatment ID:TR002283
Treatment Summary:E6-1 Jurkat cells were transfected with a pool of double-stranded siRNAs targeting CCT1 (5’-CCAUUGGAGACUUGGUAAA-3’), CCT2 (5’-UGGUAAACCUCGAGACAAC-3’), CCT4 (5’- AGGUGGUGCUCCAGAAAUA-3’) and CCT5 (5’-CCAGACAGGUGAAGGAGAU-3’). As control, cells were transfected with a nonspecific siRNA (5’-UUCUCCGAACGUGUGCACG-3’). Cells were resuspended in Opti-MEM (Gibco; 1 x 106 cells per ml) with 1.2 M of each siRNA to a total of 5 M and electroporated with Gene PulserXcell (Bio-Rad) at 240 mV and 95 mA in 4 mm cuvettes (Bio-Rad). Silencing was effective from 48 h until 72 h after the transfection step.

Sample Preparation:

Sampleprep ID:SP002277
Sampleprep Summary:Five biological replicate containing 3 × 106 cells were collected and stored at -80°C. The cell pellets were thaw on ice and subjected to three freeze–thaw cycles for complete cell disruption and protein precipitation. Briefly, samples were suspended in 250 µL freshly prepared methanol:acetic acid (98:2 v/v) solution, vortex-mixed, placed in liquid nitrogen for 10s and thaw in an ice bath (for 10s) three times. Subsequently samples were centrifuge at 18000g for 20 min. at 10°C. Supernatants were collected and lipids were extracted with methyl-tert-butylether (MTBE) as described (Matyash et al., 2008). 400 µL of organic phase were dried-out in speedvac and resuspended in 50 µL of ACN:H2O (20:80, v:v) just before injection. In order to assess the reproducibility and robusteness of the methodology, quality control samples (QC) were prepared by polling together one CCT and one CTRL sample’s supernatant and following the same extraction procedures. Dried extracted were resuspended in 50 µL of ACN:H2O (20:80, v:v) just before injection.
