MPRIP (Myosin Phosphatase Rho Interacting Protein)

The sustained response, even at reduced doses, highlights the potential for targeted therapies in managing NSCLC with MPRIP-ROS1 fusion. This case also underscores the importance of comprehensive genomic profiling using hybrid capture-based next-generation sequencing to identify rare driver gene alterations that may not be detected by conventional target sequencing-based methods.

One month after initiating the treatment, the patient achieved a hematological response consistent with complete response (CR) criteria. Imatinib therapy has been well-tolerated without reported adverse events, and a 1-year molecular assessment confirmed the achievement of complete molecular response (CMR).

Among them, compound 10o exhibited superior antiproliferative activity in the Ba/F3-MPRIP-TRKAG667C cell line compared to selitrectinib, one of the most advanced selective next-generation TRK inhibitors, and it potently inhibited TRK kinase activity with high selectivity...In vivo treatment with 10o·HCl led to a marked delay in tumor growth in a Ba/F3-MPRIP-TRKAG667C subcutaneous tumor model. Thus, our work offers valuable insights for the development of next-generation TRK inhibitors.

Finally, univariate and multivariate analyses indicated that the risk score was significantly correlated with overall survival (P<0.05), and pathological stage could also be used independently to predict the prognosis of EC. Our study indicated that the RBP signature could serve as a prognostic biomarker of EC and provided new insights into the chemoresistance of this disease.

In addition, macrophage coculture assay suggested that HVEM overexpression inhibited M2 macrophage polarization through GM-CSF/GM-CSFRα axis. In summary, our study has demonstrated that tumor cell intrinsic HVEM is a potential tumour metastasis suppressor, which may serve as a potential target for immunotherapy.

SAMS is on a morphologic and molecular genetic spectrum with EFH, with a similar body site distribution, frequent clinical presentation as an exophytic skin tumor, and invariably benign outcomes; we conclude that SAMS should be considered a histologic variant of EFH. Some morphologically typical examples harbor alternate RET and NTRK3 fusions, such that SAMS is not an appropriate designation for this morphologic class; instead, to highlight the clinicopathologic similarities to EFH, we propose the diagnostic term "myxoid spindle cell variant of epithelioid fibrous histiocytoma."

In addition, the iPRS showed a HR of 1.81 (95% CI: 1.46-2.09) compared the highest tertile to the lowest tertile, with an enhanced AUC (0.91; 95% CI:0.85-0.97) than PRS (AUC: 0.86; 95% CI:0.76-0.95; P-  = 2.2 × 10 ). In summary, this study identified several important SNP-SNP interactions for BC risk, and developed an iPRS model for BC screening, which may help to identify the people at high-risk state of BC before early manifestation.

Our bioinformatics analysis identified KCNJ18, GPRIN2, TEKT4, HRNR, FOLR3, ESSRA, CTBP2, MPRIP, TBP, and FBXO6 may contribute to progression in NSCLC and could be used as new biomarkers for the treatment. The mechanism by which GPRIN2, KCNJ12, and TEKT4 contribute to tumorigenesis is unclear, but our results suggest they may play an important role in NSCLC and it is worth investigating in future.

Knockdown of FAP could reverse tumorigenicity and chemoresistance in CRC cells. Thus, FAP may serve as a marker for prognosis and therapeutic outcome, as well as a potential therapeutic target to overcome chemoresistance in MC patients.

Modulation of RBFOX2-regulated splicing events, such as via myosin phosphatase RHO-interacting protein (MPRIP), is associated with PDA metastases, altered cytoskeletal organization and the induction of focal adhesion formation. Our results implicate the splicing-regulatory function of RBFOX2 as a tumour suppressor in PDA and suggest a therapeutic approach for metastatic PDA.

In combination with dexamethasone, we assessed a further decrease of viability between 10 to 95%...Importantly, combination of BIBF1120 and CHZ868 showed a synergistic effect (-45%, at IC50)...Indeed, active caspase 3 increased when ruxolitinib was given in combination with chloroquine, an autophagy inhibitor (+20% vs ruxolitinib alone, p<0.01)...CHZ868 is a promising candidate for treatment of BCP-ALL carrying JAK2 fusions, showing high efficacy and specificity, both ex vivo and in vivo . Further studies will include combination with standard chemotherapy drugs with the aim to maintain its efficacy by reducing the intensity and toxicity of chemotherapy.

This study shows that despite its name, PLNTY also occurs in older adults, who frequently show BRAF V600E mutation. It also expands the spectrum of the MAPK pathway activating alterations associated with PLNTY and demonstrates recurrent chromosomal copy number changes consistent with chromosomal instability.
