NOTCH mutation

Our study analyzed the main factors that influence the prognosis of PACC patients undergoing surgery and discovered the unique genetic phenotype of PACC.

Mechanistically, IL-6 increase relies on loss of the negative control exerted by the p50 subunit on the IL-6 promoter. Our results reveal the Notch/NF-κB cross-talk in regulating myeloid-derived suppressor cell biology in T-cell leukemia, highlighting the need to consider carefully the pleiotropic effects of NF-κB-based therapy on the tumor microenvironment.

The presence of LRP1B mutation was significantly associated with longer overall survival (OS), whereas RB1 mutation and advanced TNM stage were associated with shorter OS. We identified frequently mutated genes and potential predictors of survival in patients with gastric NECs and MANECs.

Four of 10 patients were positive for PD-L1 and CD8+ T. By analyzing WES in three of these four patients, we notably identified the mutations of NOTCH1, FBXW7, and noncoding RNA intronic mutation in NOTCH2NLR in two of these three patients. This study may enable better selection of ICI therapy with CD8+ T-cell infiltration via PD-L1 expression for oral squamous cell carcinoma patients with mutations in Notch signaling pathway.

Cluster analysis by LymphGen classified 29/54 cases within definite groups, including BN2 in 14 (48.2%), ST2 in seven (24.2%) and MCD and EZB in four each (13.8%). Overall, these results indicate a preferential marginal zone origin for a consistent subgroup of HCV-associated DLBCL cases and suggest potential implications for molecularly targeted therapies.

dNKAP knockdown and oncogenic Ras, Notch, or Yki mutations show synergies in driving tumorigenesis, further supporting the tumor-suppressive role of dNKAP. In summary, this study demonstrates that dNKAP plays a tumor-suppressive role by preventing genome instability in Drosophila epithelia and thus provides novel insights into the roles of human NKAP family genes in tumor initiation and progression.

Combination treatment with idasanutlin and navitoclax, a potent Bcl-2/Bcl-xL inhibitor, induces more consistent and potent synergistic killing of T-ALL PDX lines in vitro than venetoclax, a Bcl-2 specific inhibitor. Moreover, a marked synergic response to combination treatment with idasanutlin and navitoclax was seen in vivo in all four T-ALL xenografts tested, with a significant increase in overall survival in the combination treatment group. Collectively, these preclinical data show that the combination of idasanutlin and navitoclax is highly active in T-ALL and may merit consideration in the clinical setting.

However, HBV positive with NOTCH unmutated had no statistical difference in prognosis compared with HBV-negative patients (p = 0.1706 for OS and p = 0.2387 for TTT), which indicated that NOTCH pathway mutation contributed to inferior prognosis in HBV-infected CLL. In conclusion, a cohort of CLL patients with HBV positive displayed a worse clinical outcome and the status of the NOTCH signaling pathway might play a crucial role.

Mutations in ZMYM3 are mainly loss-of-function, associate with NOTCH1 signaling mutations and shorten TFT in CLL patients, suggesting that ZMYM3 mutational status may be a useful marker in the management of early stage CLL patients. Moreover, ZMYM3 mutations reduce histone H4 acetylation and cooperate with NOTCH1 mutations to dysregulate gene-expression, leading to impair DNA damage response and apoptosis evasion.

Venetoclax showed an additive benefit in 3 lines, but was only synergistic in 1 of 5 lines tested...We also evaluated ruxolitinib in combination with idasanutlin, as recent work has shown overlapping responses to inhibitors of Jak/Stat or Bcl-2 (Yuan et al...Idasanutlin and combination therapy samples clustered closely in PCA analysis, with p53 response a strongly-induced pathway, as expected. Our data suggest that the rational combination of idasanutlin and navitoclax is highly active against T-ALL, with greater synergic opportunity compared to other available idasanutlin combination treatments, through induction of a p53-dependent apoptotic cell death.

Therefore, it is of interest to document the molecular docking analysis of cetuximab with the NOTCH signaling targets such as NOTCH1, NICD, and HES1. These results suggest that targeting the NOTCH signaling with cetuximab might leads to the better outcome for suppression of invasion and metastasis in oral carcinoma.
