KRAS mutation + TP53 mutation

We propose a model whereby TGFβ induces LINC00313 in order to regulate the expression of hallmark Wnt pathway genes, in co-operation with SWI/SNF. By modulating key genes of the Wnt pathway, LINC00313 fine-tunes Wnt/TCF/LEF-dependent transcriptional responses and promotes cholangiocarcinogenesis.

The mPRS classification accurately segregated groups of AML patients treated with HMA plus Ven. In these patients, N/KRAS and TP53 mutations appear to negatively impact outcomes and therefore new treatment approaches are warranted.

G12C/TP53 co-mutations identify a subset of patients with a very favorable long-term survival with ICI monotherapy, mediated by highly active IFNγ signaling in a pro-inflammatory TME.

GGN-featured lung adenocarcinoma is dominated by non-high-risk female patients. Shorter preoperative follow-up in the non-high-risk group and no statistical difference in GGN detection way suggests the existing screening criteria for high-risk population may not suit GGN-featured lung cancer. In addition, the incidences of KRAS and TP53 mutations are higher in the high-risk group.

N6F11 also sensitized immune checkpoint blockade that targeted CD274/PD-L1 in advanced cancer models, including genetically engineered mouse models of pancreatic cancer driven by KRAS and TP53 mutations. These findings may establish a safe and efficient strategy to boost ferroptosis-driven antitumor immunity.

Purposes Study safety and efficacy of olverembatinib or ponatinib and azacitidine (AZA) in this setting. KRAS and TP53 mutations and PFKFB3::LINC02649 fusions had predictive impact on outcomes. Determining whether adding azacitidine to a 3rd-generation TKI requires a randomized controlled trial.

GT19715 also enhanced cell death induced by dexamethasone. Targeted protein degradation of c-MYC induces promising anti-leukemia efficacy in T-ALL cells in vitro and in vivo. Further mechanistic and in vivo studies are ongoing.

However, several predictive factors play a crucial role in the efficacy of stereotactic body radiation therapy, such as the number and size (volume) of metastatic liver lesions, the primary tumor site (histology), molecular biomarkers (e.g., KRAS and TP53 mutation), the use of systemic therapy prior to SBRT, the radiation dose, and the use of advanced technology and organ motion management during SBRT. These prognostic factors need to be considered when clinical trials are designed to evaluate the efficacy of SBRT for liver metastases.

Notably, overexpressing TFEB in CD11c+ dendritic cells augmented tumor-specific CD4 T-cell responses, yet reduced CD8 T-cell activities, suggesting a potential shift towards a tolerogenic immune environment in NSCLC. Conclusions Conclusively, our insights into TFEB’s function in NSCLC highlight the complex relationship between tissue-specific elements and tumor immunogenicity, offering avenues for refining immunotherapeutic strategies.

PDAC patients with a high ADH1B expression had better disease-specific survival (DSS) and overall survival (OS) and ADH1B was an independent prognostic biomarker for both DSS (HR = 0.89, 95% CI = 0.80-0.99, P = 0.045) and OS (HR = 0.90, 95% CI = 0.82-0.99, P = 0.044) in multivariate analysis. In conclusion, PDAC with high ADH1B expression had less cell proliferation and malignant features, along with higher immune cell infiltration, and had a better prognosis.

It was interpreted as serous cystadenoma and the risk for progression was low. Molecular analysis of pancreatic cysts with PancreaSeq® is useful in accurate diagnosis, especially when cytologic material is non-diagnostic and helps improve patient management.

DNA damage repair and homologs recombinant repair deficiencies were significantly associated with high TMB in ICCA cases. In conclusion, we found that certain genetic mutations of TP53 and KRAS could predict poor prognosis in ICCA patients.

Moreover, high-AMRS group was also more sensitive to paclitaxel, cisplatin, and docetaxel. Overall, we constructed an AA-metabolism prognostic model, which provided a powerful prognostic predictor for the clinical treatment of pancreatic cancer.

Barcoding sequencing will allow the determination of tumor number and size and, therefore, the assessment of this SWI/SNF subunits oncogenic potential. Further transcriptional experiments will allow us to identify the molecular pathways altered by SWI/SNF deficiency in our model.ConclusionWe have successfully generated all necessary tools to perform Tuba-seq experiments to study at the molecular level the role of SWI/SNF alteration in a mouse model of LUAD.

ACC clearly harbors different genomics compared with PDAC, possibly accounting for differences in treatment efficacy.

This is the first-in-human experience administering Sleeping Beauty TCR-T cells. Signs of efficacy, safety and persistence of TCR-T cells was observed. Thus, this treatment has promise for patients with solid tumors expressing shared mutations in driver genes.

Background: Cisplatin resistance occurs in up to 30% of patients with advanced germ cell tumors (GCTs)... This study provides evidence that chemo naïve GCTs with mutations in TP53, KRAS, KIT or MDM2 CNA have higher expression of genes associated with resistance to platinum-based chemotherapy. These findings contribute to a better understanding of the molecular characteristics of GCTs and may inform prognosis and treatment.

This was also the case in the context of additional activation of the Wnt signaling pathway. Thus, p53 protects against formation of extrahepatic biliary precancerous lesions in the context of oncogenic Kras.

In mice, Ser21 of TPI1 is a Cys residue which can be oxidized to alter TPI1 activity without a need for SIKs or LKB1. Our findings suggest this metabolic flexibility is critical in rapidly growing cells with KRAS and TP53 mutations, explaining why loss of LKB1 creates a liability in these tumors.

We report on the association of cfDNA with response durability for patients undergoing treatment with a novel metronomic chemotherapy regimen (gemcitabine, nab-paclitaxel, capecitabine, cisplatin, irinotecan; GAX-CI) for metastatic PDAC. This investigation offers encouraging evidence that cfDNA may prove to be a valuable diagnostic tool to guide clinical management.

We proposed the senescence subtypes of CRC for the first time and demonstrated the characteristics of different subtypes. We also found potential treatment interventions for each subtype, which can promote the precision treatment of CRC patients.

Here we describe multiple independent combinations of KRAS and TP53 mutations leading to convergent functional outcomes for tumor cells, in the context of patient-specific gene mutation landscapes. Recurrent patterns of paired mutations with common cellular function dysregulation outcomes highlight core underlying mechanisms of pancreatic tumor evolution.

Our study suggests spatial and longitudinal tumor heterogeneity and reports emerging mutations in ctDNA over time in HNSCC. Prognostic significance characterization of the ctDNA dominant clone allele frequency is ongoing.

Conclusions. Immunohistochemistry and mutation analyses revealed tumorigenesis of rectal carcinoma with sarcomatoid components correlated with EMT and TP53 mutations.

To our knowledge, there is no study evaluating the mutations of Kras and TP53 in this way in the literature. Co-humations must therefore be taken into account before prescription of immune control point inhibitors.

ICIs combined with ChT improved clinical outcomes over Beva combined with ChT as first-line therapy for adenocarcinoma patients without driver gene alterations, especially in patients with PD-L1 ≥ 1%.

MED12 mutations have been recently identified in other tumors. Recurrent detection of MED12 mutations in UC-OGC warrants further evaluation of its roles in this unique tumor.

In conclusion, GCT with SM are characterized by widespread aneuploidy, a distinct epigenetic signature and the presence of mutations that are otherwise rare in testicular GCT without SM. The similarity of the mutational and DNA methylation profiles of different histologic types of SM suggests that the identification of SM components could be more important than their precise histologic subclassification, pending confirmation by further studies.

In comparison, high IRGPRI was associated with cancer-related pathways, low expression of CTLA4, high KRAS and TP53 mutation rate, more infiltration of M2 macrophages, and less benefit from ICIs therapies. This IRGPRI is an encouraging biomarker to define the prognosis, immune and molecular features, and benefits from ICIs treatments in PAAD.

Immune subtyping of KRAS-TP53 co-altered PDAC reveals conflation of intratumor heterogeneity with progenitor-like stemness properties. Coalescing these distinct molecular characteristics into a KRAS-TP53 co-altered "immunoregulatory program" predicts chemoresistance in metastatic PDAC patients enrolled in the COMPASS trial, as well as worse overall survival.

Compared to the previously reported cases, our unique case of primary DICER1-sarcoma also demonstrated neurofilament and chromogranin positivity, and genomic instability with loss of chromosome 4p, 4q, 8p, 11p, and 19p, as well as gains in chromosome 7p, 9p, 9q, 13q, and 15q on copy variant analysis. The detailed sequencing and methylation information discovered in this unique case of DICER1-sarcoma will hopefully help further our understanding of this rare and emerging entity.

Intriguingly, KRAS wild-type cases had a better short-term prognosis despite the lymph node status. In conclusion, our work highlights that the combination of KRAS mutation with the age of the patient and the lymph node status may help in predicting the outcome in PDAC patients.

These results indicate that somatic evolution contributes to clonal expansions in the normal colon and that this process is enhanced in individuals with cancer, particularly in those with early-onset colorectal cancer. This work suggests prevalent somatic evolution in the normal colon of patients with colorectal cancer, highlighting the potential of using ultrasensitive gene sequencing to predict disease risk.

Strikingly, MMRi62 completely abrogated metastasis of orthotopic tumors to distant organs, which is consistent with MMRi62's ability to inhibit cell migration and invasion in vitro. These findings identified MMRi62 as a novel ferroptosis inducer capable of suppressing PDAC growth and overcoming metastasis.

Despite the small sample size, the current cohort indicates that tumors harboring mutations involving STK11 and TP53 are associated with unfavorable morphology and high TNM stage. In addition, these tumors may benefit from treatment with immunotherapy.

However, no association was noticed with the presence of any singular mutation and occurrence of subsequent adenoma or CRC. Our data supports the multistep model of gradual accumulation of mutations, especially in the driver genes, such as APC, TP53 and KRAS.

Although the use of immunotherapy in PDAC remains an unmet challenge, recent insights indicated a potentially significant role of the PD-L1/Notch3 axis in SCP, opening new horizons for immunotherapy in this cancer subtype. In this review, we described the most important clinic-pathologic features of SCP, with a specific focus on their molecular landscape and the potential targets for precision oncology.
