As the success of chemotherapeutic agents is often questioned by the occurrence of multidrug resistance (MDR), a multiple cross-resistance towards different anti-cancer drugs represent a major obstacle to cancer treatment. The present study has clarified the involvement of the carbon metabolites in a more aggressive tumor colon adenocarcinoma phenotype and in a chemoresistant mesothelioma, and the role of pyruvate treatment in the reversion of the potentially related resistance. For the first time, we have shown that human colon adenocarcinoma cells (HT29) and its chemoresistant counterpart (HT29-dx) displayed different carbon metabolism: HT29-dx cells had a higher glucose consumption compared to HT29 cells, whereas human malignant mesothelioma (HMM) cells showed a lower glucose consumption compared to HT29 cells, accompanied by a lower pyruvate production and, consequently, a higher production of lactate. When treated with pyruvate, both HT29-dx and HMM cells exhibited a re-established accumulation of doxorubicin and a lower survival ability, a decreased activity of multidrug resistance protein 1 (MRP1) and a restored mitochondrial respiratory chain function, improving the effectiveness of the chemotherapeutic agents in these resistant cancer cells.<\/jats:p>","DOI":"10.3390\/ijms19113550","type":"journal-article","created":{"date-parts":[[2018,11,14]],"date-time":"2018-11-14T02:42:41Z","timestamp":1542163361000},"page":"3550","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Pyruvate Treatment Restores the Effectiveness of Chemotherapeutic Agents in Human Colon Adenocarcinoma and Pleural Mesothelioma Cells"],"prefix":"10.3390","volume":"19","author":[{"given":"Eleonora","family":"Mungo","sequence":"first","affiliation":[{"name":"Department of Oncology, University of Torino, Via Santena 5\/bis, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0951-7340","authenticated-orcid":false,"given":"Loredana","family":"Bergandi","sequence":"additional","affiliation":[{"name":"Department of Oncology, University of Torino, Via Santena 5\/bis, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iris Chiara","family":"Salaroglio","sequence":"additional","affiliation":[{"name":"Department of Oncology, University of Torino, Via Santena 5\/bis, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7335-5801","authenticated-orcid":false,"given":"Sophie","family":"Doublier","sequence":"additional","affiliation":[{"name":"Department of Oncology, University of Torino, Via Santena 5\/bis, 10126 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.3322\/caac.21442","article-title":"Cancer statistics, 2018","volume":"68","author":"Siegel","year":"2018","journal-title":"Cancer J.
