Article Abstract
Akt3, a serine/threonine kinase within the PI3K-Akt-mTOR signaling pathway, is overactivated in various cancers, making it a promising therapeutic target. The research aimed to create compounds that selectively degrade Akt3, sparing Akt1 and Akt2, to enhance the clinical benefits. A series of compounds with different linkers and E3 ligands were synthesized and evaluated for their degradation potencies and selectivity. The findings showed that the linker length and E3 ligand type significantly influenced Akt3 degradation. Compound was identified as a potent and selective Akt3 degrader in multiple cancer cell lines. Proteomic analysis confirmed the specificity of this degrader for Akt3, with minimal off-target effects. However, compound did not exhibit significant antiproliferative activity in the cancer cell lines.

To maintain genomic stability, cells have evolved complex mechanisms collectively known as the DNA damage response (DDR), which includes DNA repair, cell cycle checkpoints, apoptosis, and gene expression regulation. Recent studies have revealed that long non-coding RNAs (lncRNAs) are pivotal regulators of the DDR. Beyond their established roles in recruiting repair proteins and modulating gene expression, emerging evidence highlights two particularly intriguing functions.

The generation of reactive oxygen species (ROS) through nanozyme-mediated sonocatalytic therapy has demonstrated remarkable therapeutic efficacy in the field of cancer. Nevertheless, it remains a significant challenge for nanozymes with a single catalytic active center to generate sufficient ROS via Fenton or Fenton-like reactions to effectively induce tumor cell death. In order to enhance the catalytic efficacy, we devised and synthesized a multiple active centre and mitochondrial-targeted perovskite nanozyme (NCFP), doped with cobalt (Co) element, and incorporated 4-carboxybutyltriphenylphosphonium bromide (TPP) as a mitochondrial targeting marker for ultrasound (US)-assisted enzyme-like catalytic treatment of tumors.

Purpose: mutations are classically seen in non-small cell lung cancers (NSCLCs), and EGFR-directed inhibitors have changed the therapeutic landscape in patients with -mutated NSCLC. The real-world prevalence of -mutated ovarian cancers has not been previously described. We aim to determine the prevalence of pathogenic or likely pathogenic mutations in ovarian cancer and describe a case of -mutated metastatic ovarian cancer with a durable response to osimertinib, an EGFR-directed targeted therapy.

Purpose: Tumor comprehensive genomic profiling (CGP) may detect potential germline pathogenic/likely pathogenic (P/LP) alterations as secondary findings. We analyzed the frequency of potentially germline variants and large rearrangements (LRs) in the RATIONAL study, an Italian multicenter, observational clinical trial that collects next-generation sequencing-based tumor profiling data, and evaluated how these findings were managed by the enrolling centers.
Patients And Methods: Patients prospectively enrolled in the pathway-B of the RATIONAL study and undergoing CGP with the FoundationOne CDx assays were included in the analysis.

Background: Accurate evaluation of the invasion depth of superficial esophageal squamous cell carcinoma (SESCC) is crucial for optimal treatment. While magnifying endoscopy (ME) using the Japanese Esophageal Society (JES) classification is reported as the most accurate method to predict invasion depth, its efficacy has not been tested in the Western world. This study aims to evaluate the interobserver agreement of the JES classification for SESCC and its accuracy in estimating invasion depth in a Brazilian tertiary hospital.
