Study Title | Metabolic characterization of the polar endometabolome of Triple-Negative Breast Cancer parental and cDDP-resistant cells (part 2) |
Study Type | NMR-based metabolomics of polar endometabolome of cultured cells |
Study Summary | Platinum (Pt(II)) drugs, e.g. cisplatin (cDDP), are some of the most used chemotherapeutic agents, yet tumor acquired resistance and high toxicity are still current drawbacks. Metabolomics can measure the metabolic response of drug-exposed cells, unveiling insight into drug mechanisms and metabolic markers of drug efficacy, toxicity and resistance. The present 1H NMR metabolomics study aims to describe the effects of cDDP and Pd2Spm on the polar endometabolome of both MDA-MB-231 cDDP-sensitive and cDDP-resistant cell lines, aiming to describe metabolic markers of (i) resistance upon cDDP treatment, and (ii) the effect of Pd2Spm on the established cDDP-resistant cells. The former observations will give helpful insights about the metabolic features of cDDP-resistance during treatment, and enlighten on the potential role of Pd2Spm in metabolically affecting/tackling cDDP-resistance. |

Collection:
Collection ID: | CO003088 |
Collection Summary: | MDA-MB-231 parental and MDA-MB-231/R cDDP-resistant cell lines were seeded at a density of 3 × 10^4 cells/cm2 onto 13.55 cm diameter Petri dishes, cultured in a humidified atmosphere of 5% CO2 at 37 ◦C and allowed to adhere for 24 h (t = 0 h). After this, the experiment was initiated by adding stock solutions of each drug to achieve the corresponding half of maximal inhibitory effect IC50 values: 1.0 µM cDDP and 7.9 μM Pd2Spm. Phosphate-buffer saline was used in control groups. Then, cells were incubated and collected at t = 24 h and t = 48 h, with basis on the population (25.5 ± 0.9 h and 30.6 ± 1.1 h for MDA-MB-231 and MDA-MB-231/R cells, respectively). At each time-point, cells were harvested using a 0.25% (v/v) trypsin-EDTA solution, washed twice with PBS and centrifuged (300 g, 5 min, 20 ◦C). The cell pellet was directly stored at − 80 ◦C until analysis. Three independent experiments with triplicates were performed for each cell type and time-point. |
