| Study Title | Respiration defects limit serine synthesis required for lung cancer growth and survival - Effect of Polg mutation in NSCLC tumor derived lines (TDCLs) |
| Study Summary | This study investigates the impact of mtDNA mutation burden induced by the PolGD256A mutation in NSCLC. Using in vitro models (TDCLs), we characterized we collected conditioned medium to mesure glucose and serine consumption. Here we found that mitochondria impairment cause more use of glucose and less use of serine from the culture medium.

| Project Title: | Respiration defects limit serine synthesis required for lung cancer growth and survival |
| Project Type: | Pool Size Metabolomic in vivo |
| Project Summary: | Mitochondrial function supports energy and anabolic metabolism. Pathogenic mitochondrial DNA (mtDNA) mutations impair these processes, causing mitochondrial diseases. Their role in human cancers is less clear; while some cancers harbor high mtDNA mutation burden, others do not. Here we show that a proofreading mutant of DNA polymerase gamma (PolGD256A) increases the mtDNA mutation burden in non-small-cell lung cancer (NSCLC). This mutation promotes the accumulation of defective mitochondria, reduces tumor cell proliferation and viability, and improves cancer survival. In NSCLC, pathogenic mtDNA mutations enhance glycolysis and create a glucose dependency to support mitochondrial energy, but at the expense of a lower NAD⁺/NADH ratio that hinders de novo serine synthesis. Thus, mitochondrial function in NSCLC is essential for maintaining adequate serine synthesis, which in turn supports the anabolic metabolism and redox homeostasis required for tumor growth, explaining why these cancers preserve functional mtDNA. |

Sample Preparation:
| Sampleprep ID: | SP004026 |
| Sampleprep Summary: | Conditioned culture media exposed to 72h of PGKP and KP TDCLs. The analyses presented in this study were performed using the conditioned medium derived from the cell culture described in study 5752. The objective was to identify metabolites synthesized from glucose in the culture medium. In the table, where the genotype of the samples is specified as “Fresh medium,” it refers to unconditioned culture medium (not exposed to cells), which serves as a baseline for metabolite analysis of the conditioned medium from KP and PGKP TDCLs. |
