Targeting c-MYC and gain-of-function p53 through inhibition or degradation of the kinase LZK suppresses the growth of HNSCC tumors.

The worldwide annual frequency and lethality of head and neck squamous cell carcinoma (HNSCC) is not improving, and thus, new therapeutic approaches are needed. Approximately 70% of HNSCC cases have either amplification or overexpression of , which encodes the kinase LZK. Here, we found that LZK is a therapeutic target in HNSCC and that small-molecule inhibition of its catalytic function decreased the viability of HNSCC cells with amplified .

Impact of developmental state, p53 status, and interferon signaling on glioblastoma cell response to radiation and temozolomide treatment.

Glioblastoma (GBM) tumors exhibit extensive genomic, epigenomic, and transcriptional diversity, with significant intratumoral heterogeneity, complicating standard treatment approaches involving radiation (RT) and the DNA-alkylating agent temozolomide (TMZ). In this study, we employed an integrative multi-omics approach, including targeted proteomics, transcriptomics, genomics, and DNA methylation profiling, to investigate the response of a representative panel of GBM patient-derived cancer stem cells (CSCs) to astrocytic differentiation and RT and TMZ treatments. Differentiated CSC progenies retained the expression of key stemness genes and survival pathways, while activating the BMP-Smad signaling pathway and upregulating extracellular matrix components.

Mother-adolescent communication and father-adolescent communication: Analyzing a 4-week family intervention using multi-informant data.

Families manage daily conflict through communication and healthy family communication is critical to promoting better family relationships and youth adjustment. Community families without high-risk factors, such as domestic dispute or clinical problems, are no less affected by the ramifications of poor communication and conflict management. However, there is limited translational research on community families analyzing the changes in parent-adolescent communication quality.

Managing Pregnancies of Unknown Location With the M4 Prediction Model or the NICE Algorithm: A Randomised Controlled Trial With Cross-Sectional Diagnostic Accuracy Data.

Objective: To determine the diagnostic performance and clinical utility of the M4 prediction model and the NICE algorithm managing women with pregnancy of unknown location (PUL).

Design: The study has a superiority design regarding specificity for non-ectopic pregnancy for M4, given that the primary outcome of sensitivity for ectopic pregnancy (EP) is non-inferior in comparison with the NICE algorithm.

Setting: Emergency gynaecology units in Sweden.

Automated tuning of a ring-assisted MZI-based interleaver for Kerr frequency combs.

We demonstrate a compact ring-assisted Mach-Zehnder interferometer (RAMZI)-based silicon photonic interleaver with a 400 GHz free spectral range (FSR), featuring flat passbands exceeding a spectral range of 50 nm. Additionally, we introduce a novel, to the best of our knowledge, add-on structure and tuning method enabling automated compensation for fabrication imperfections, precise shaping of the RAMZI flat-top passbands, and alignment with Kerr comb lines. Experimental results have shown successful interleaving of eight channels of distributed-feedback (DFB) lasers as well as a 200 GHz Kerr comb, both achieving an extinction ratio of approximately 20 dB.
