Postoperative adjuvant immunotherapy for pathological stage II-IVa esophageal squamous cell carcinoma after radical surgery does not improve disease-free recurrence rates.

Background/objectives: Postoperative adjuvant therapy for esophageal squamous cell carcinoma (ESCC) primarily includes chemotherapy and chemoradiotherapy. The survival benefits of postoperative adjuvant therapy for R0-resected ESCC remain controversial. Immunotherapy is being gradually applied perioperatively for esophageal cancer, but the efficacy of postoperative immunotherapy in ESCC is unclear.

Deep learning identification of novel autophagic protein-protein interactions and experimental validation of Beclin 2-Ubiquilin 1 axis in triple-negative breast cancer.

Background: Triple-negative breast cancer (TNBC), characterized by its lack of traditional hormone receptors and HER2, presents a significant challenge in oncology due to its poor response to conventional therapies. Autophagy is an important process for maintaining cellular homeostasis, and there are currently autophagy biomarkers that play an effective role in the clinical treatment of tumors. In contrast to targeting protein activity, intervention with protein-protein interaction (PPI) can avoid unrelated crosstalk and regulate the autophagy process with minimal interference pathways.

enhances the development of lung adenocarcinoma by regulating the glycolysis pathway.

Background: To investigate SCL/TAL 1 interrupting locus ()'s role and prognostic significance in lung adenocarcinoma (LUAD) progression, we examined and E2 promoter binding factor 1 (E2F1) expression and their impacts on LUAD prognosis using Gene Expression Profiling Interactive Analysis (GEPIA).

Methods: Functional assays including CCK-8, wound-healing, 5-ethynyl-2-deoxyuridine (EdU), Transwell assays, and flow cytometry, elucidated and E2F1's effects on cell viability, proliferation, apoptosis, and migration. Gene set enrichment analysis (GSEA) identified potential pathways, while metabolic assays assessed glucose metabolism.

Mechanisms of gut homeostasis regulating Th17/Treg cell balance in PMOP.

Postmenopausal osteoporosis (PMOP) is a metabolic bone disease driven by estrogen deficiency, primarily manifesting as reduced bone mass and heightened fracture risk. Its development is intricately linked to the balance between Th17 and Treg cells. Recent studies have highlighted the significant role of gut homeostasis in PMOP.

High-Speed Sequential DNA Computing Using a Solid-State DNA Origami Register.

DNA computing leverages molecular reactions to achieve diverse information processing functions. Recently developed DNA origami registers, which could be integrated with DNA computing circuits, allow signal transmission between these circuits, enabling DNA circuits to perform complex tasks in a sequential manner, thereby enhancing the programming space and compatibility with various biomolecules of DNA computing. However, these registers support only single-write operations, and the signal transfer involves cumbersome and time-consuming register movements, limiting the speed of sequential computing.
