concurrent mutations in the oncogene KRAS and the tumor suppressor STK11 encoding the kinase LKB1 result in aggressive tumors \ |

prone to metastasis but with liabilities arising from reprogrammed metabolism. \ |
|
We previously demonstrated perturbed nitrogen metabolism and addiction to an unconventional pathway of pyrimidine synthesis in \ |
|
KRAS/LKB1 co-mutant (KL) cancer cells. To gain broader insight into metabolic reprogramming in NSCLC, \ |
|
we analyzed tumor metabolomes in a series of genetically engineered mouse models with oncogenic KRAS combined with mutations in LKB1 or p53. \ |
|
Metabolomics and gene expression profiling pointed towards an activation of the hexosamine biosynthesis pathway (HBP), \ |
|
another nitrogen-related metabolic pathway, in both mouse and human KL mutant tumors. KL cells contain high levels of HBP metabolites, \ |
|
higher flux through the HBP pathway and elevated dependence on the HBP enzyme Glutamine-Fructose-6-Phosphate Transaminase 2 (GFPT2). \ |
|
GFPT2 inhibition selectively reduced KL tumor cell growth in culture, xenografts and genetically-modified mice. \ |
|
Our results define a new metabolic vulnerability in KL tumors and provide a rationale for targeting GFPT2 in this aggressive NSCLC subtype.'}, |

{'role':'user', 'content':'Abstract: Rationale: NRF2, a redox sensitive transcription factor, \ |
|
is up-regulated in head and neck squamous cell carcinoma (HNSCC), however, the associated impact and regulatory mechanisms remain unclear. \ |
|
Methods: The protein expression of NRF2 in HNSCC specimens was examined by IHC. The regulatory effect of c-MYC on NRF2 was validated by ChIP-qPCR, \ |
|
RT-qPCR and western blot. The impacts of NRF2 on malignant progression of HNSCC were determined through genetic manipulation and \ |
|
pharmacological inhibition in vitro and in vivo. The gene-set enrichment analysis (GSEA) on expression data of cDNA microarray combined with \ |
|
ChIP-qPCR, RT-qPCR, western blot, transwell migration/ invasion, cell proliferation and soft agar colony formation assays were used to \ |
|
investigate the regulatory mechanisms of NRF2. Results: NRF2 expression is positively correlated with malignant features of HNSCC. \ |
|
In addition, carcinogens, such as nicotine and arecoline, trigger c-MYC-directed NRF2 activation in HNSCC cells. \ |
|
NRF2 reprograms a wide range of cancer metabolic pathways and the most notable is the pentose phosphate pathway (PPP). \ |
|
Furthermore, glucose-6-phosphate dehydrogenase (G6PD) and transketolase (TKT) are critical downstream effectors of NRF2 that \ |
|
drive malignant progression of HNSCC; the coherently expressed signature NRF2/G6PD/TKT gene set is a potential prognostic \ |
|
biomarker for prediction of patient overall survival. Notably, G6PD- and TKT-regulated nucleotide biosynthesis is more important than \ |
|
redox regulation in determining malignant progression of HNSCC. Conclusions: Carcinogens trigger c-MYC-directed NRF2 activation. \ |
|
Over-activation of NRF2 promotes malignant progression of HNSCC through reprogramming G6PD- and TKT-mediated nucleotide biosynthesis. \ |
|
Targeting NRF2-directed cellular metabolism is an effective strategy for development of novel treatments for head and neck cancer.'}, |

"Background: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer, \ |
|
characterized high rates of tumor protein 53 (p53) mutation and limited targeted therapies. Despite being clinically advantageous, \ |
|
direct targeting of mutant p53 has been largely ineffective. Therefore, we hypothesized that there exist pathways upon which p53-mutant \ |
|
TNBC cells rely upon for survival. Methods: In vitro and in silico drug screens were used to identify drugs that induced preferential death in \ |
|
p53 mutant breast cancer cells. The effects of the glutathione peroxidase 4 (GPX4) inhibitor ML-162 was deleniated using growth and death assays, \ |
|
both in vitro and in vivo. The mechanism of ML-162 induced death was determined using small molecule inhibition and genetic knockout. \ |
|
Results: High-throughput drug screening demonstrated that p53-mutant TNBCs are highly sensitive to peroxidase,cell cycle, cell division, and \ |
|
proteasome inhibitors. We further characterized the effect of the Glutathione . Peroxidase 4 (GPX4) inhibitor ML-162 and demonstrated that \ |
|
ML-162 induces preferential ferroptosis in p53-mutant, as compared to p53-wild type, TNBC cell lines. Treatment of p53-mutant xenografts with \ |
|
ML-162 suppressed tumor growth and increased lipid peroxidation in vivo. Testing multiple ferroptosis inducers demonstrated p53-missense mutant, \ |
|
and not p53-null or wild type cells, were more sensitive to ferroptosis, and that expression of mutant TP53 genes in p53-null cells sensitized \ |
|
cells to ML-162 treatment. Finally, we demonstrated that p53-mutation correlates with ALOX15 expression, which rescues ML-162 induced ferroptosis. \ |
|
Conclusions: This study demonstrates that p53-mutant TNBC cells have critical, unique survival pathways that can be effectively targeted. \ |
|
Our results illustrate the intrinsic vulnerability of p53-mutant TNBCs to ferroptosis, and highlight GPX4 as a promising target for the \ |
|
precision treatment of p53-mutant triple-negative breast cancer." |
