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: Background: Thymidylate synthase (TYMS) is a successful chemotherapeutic target for anticancer therapy. \
Numerous TYMS inhibitors have been developed and used for treating gastrointestinal cancer now, but they have limited clinical benefits due to \
the prevalent unresponsiveness and toxicity. It is urgent to identify a predictive biomarker to guide the precise clinical use of TYMS inhibitors. \
Methods: Genome-scale CRISPR-Cas9 knockout screening was performed to identify potential therapeutic targets for treating gastrointestinal tumours \
as well as key regulators of raltitrexed (RTX) sensitivity. Cell-based functional assays were used to investigate how \
MYC regulates TYMS transcription. Cancer patient data were used to verify the correlation between drug response and MYC and/or TYMS mRNA levels. \
Finally, the role of NIPBL inactivation in gastrointestinal cancer was evaluated in vitro and in vivo. \
Findings: TYMS is essential for maintaining the viability of gastrointestinal cancer cells, and is selectively inhibited by RTX. \
Mechanistically, MYC presets gastrointestinal cancer sensitivity to RTX through upregulating TYMS transcription, \
supported by TCGA data showing that complete response cases to TYMS inhibitors had significantly higher MYC and \
TYMS mRNA levels than those of progressive diseases. NIPBL inactivation decreases the therapeutic responses of \
gastrointestinal cancer to RTX through blocking MYC. Interpretation: Our study unveils a mechanism of how TYMS is \
transcriptionally regulated by MYC, and provides rationales for the precise use of TYMS inhibitors in the clinic.'},

{'role':'user', 'content':'Abstract: Studies have characterized the immune escape landscape across primary tumors. \
However, whether late-stage metastatic tumors present differences in genetic immune escape (GIE) prevalence and dynamics remains unclear. \
We performed a pan-cancer characterization of GIE prevalence across six immune escape pathways in 6,319 uniformly processed tumor samples. \
To address the complexity of the HLA-I locus in the germline and in tumors, we developed LILAC, an open-source integrative framework. \
One in four tumors harbors GIE alterations, with high mechanistic and frequency variability across cancer types. \
GIE prevalence is generally consistent between primary and metastatic tumors. We reveal that GIE alterations are selected for \
in tumor evolution and focal loss of heterozygosity of HLA-I tends to eliminate the HLA allele, presenting the largest neoepitope repertoire. \
Finally, high mutational burden tumors showed a tendency toward focal loss of heterozygosity of HLA-I as the immune evasion mechanism, \
whereas, in hypermutated tumors, other immune evasion strategies prevail.'},

"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."

["T cells acquire a regulatory phenotype when their T cell antigen receptors (TCRs) experience an intermediate- to high-affinity \
interaction with a self-peptide presented via the major histocompatibility complex (MHC). Using TCRβ sequences from flow-sorted human cells, \
we identified TCR features that promote regulatory T cell (Treg) fate. From these results, we developed a scoring system to quantify TCR-intrinsic \
regulatory potential (TiRP). When applied to the tumor microenvironment, TiRP scoring helped to explain why only some T cell clones maintained the \
conventional T cell (Tconv) phenotype through expansion. To elucidate drivers of these predictive TCR features, we then examined the two elements of the \
Treg TCR ligand separately: the self-peptide and the human MHC class II molecule. These analyses revealed that hydrophobicity in the third \
complementarity-determining region (CDR3β) of the TCR promotes reactivity to self-peptides, while TCR variable gene (TRBV gene) usage shapes the TCR’s \
general propensity for human MHC class II-restricted activation."
