A Variant of SLC1A5 Is a Mitochondrial Glutamine Transporter for Metabolic Reprogramming in Cancer Cells

Open access

Abstract

Glutamine is an essential nutrient that regulates energy production, redox homeostasis, and signaling in cancer cells. Despite the importance of glutamine in mitochondrial metabolism, the mitochondrial glutamine transporter has long been unknown. Here, we show that the SLC1A5 variant plays a critical role in cancer metabolic reprogramming by transporting glutamine into mitochondria. The SLC1A5 variant has an N-terminal targeting signal for mitochondrial localization. Hypoxia-induced gene expression of the SLC1A5 variant is mediated by HIF-2α. Overexpression of the SLC1A5 variant mediates glutamine-induced ATP production and glutathione synthesis and confers gemcitabine resistance to pancreatic cancer cells. SLC1A5 variant knockdown and overexpression alter cancer cell and tumor growth, supporting an oncogenic role. This work demonstrates that the SLC1A5 variant is a mitochondrial glutamine transporter for cancer metabolic reprogramming.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
