Summary: This study revealed the potential therapeutic relevance of gamma-secretase inhibition in head and neck squamous cell carcinoma (HNSCC). In vitro experiments showed significant anti-neoplastic effects, including inhibition of proliferation, migration, colony forming, and promotion of apoptosis in both HPV-positive and -negative HNSCC cell lines. The results suggest that the gamma-secretase inhibitor PF03084014 (PF) may be a viable treatment option for HNSCC, especially for HPV-induced malignancies.

Summary: Gamma-secretase is a large transmembrane protein complex consisting of four distinct units, which has garnered attention for its role in intramembrane proteolysis. The recent discovery of its atomic structure through cryo-EM has enhanced our understanding of its physiological functions and facilitated the development of novel molecules targeting gamma-secretase. This review focuses on the latest progress of gamma-secretase inhibitors and modulators in clinical and preclinical stages, as well as their potential applications in various biological indications.

Summary: Amplification of the MYCN oncogene in neuroblastoma is associated with high-risk disease and poor prognosis. This study reveals that MYCN-amplified neuroblastoma cells have reduced expression of genes involved in NOTCH receptor processing, axoneme assembly, and membrane protein proteolysis. Genes encoding gamma-secretase complex subunits, known for their role in NOTCH signaling, are down-regulated in MYCN-amplified neuroblastoma. Depletion of MYCN or inhibition of gamma-secretase activity restores the expression of gamma-secretase and NOTCH-target genes. This study provides insight into the molecular mechanisms underlying MYCN's contribution to high-risk neuroblastoma.

Summary: This article describes a model in which NOTCH may play a central role in lung infection during COVID-19. A pathway involving NOTCH signaling, furin, ADAM17, and ACE2 may increase viral entry and infection of SARS-CoV-2. NOTCH signaling can also upregulate IL-6 and pro-inflammatory mediators, and if it fails to turn down properly, it may inhibit airway regeneration during lung healing.

Summary: The Notch signaling pathway plays a supporting role in various inflammation-driven diseases, but targeting this pathway for treatment has proven challenging due to its broad involvement in regenerative and homeostatic processes. Efforts to intervene with the Notch pathway by targeting Notch ligands and/or receptors through distinct therapeutic strategies, including antibody designs, are ongoing. Lessons learned from Notch targeting in cancer treatment may help guide the development of therapeutic strategies for chronic inflammatory diseases.

Summary: Desmoid tumor (DT) is a rare fibroblastic soft-tissue neoplasm that is characterized by local aggressiveness but no metastatic potential. Aberrant activation of Wnt/beta-catenin signaling and Notch pathway is closely associated with the development and progression of DT, suggesting potential therapeutic targets. Two gamma-secretase inhibitors are currently under extensive investigation and have shown potential treatment benefits in clinical trials.

Summary: The Notch pathway transmits signals through a unique receptor-ligand interaction and functions after receptor cleavage and nuclear localization. The transcriptional regulator of the Notch pathway lies at the intersection of multiple signaling pathways, enhancing cancer aggressiveness. Preclinical and clinical evidence supports the pro-oncogenic function of Notch signaling in various tumor subtypes.

Summary: The membrane-bound Notch regulator (Mnr) supports Notch signaling by promoting the cleavage of the Notch receptor, which in turn enhances Notch receptor activation. Overexpression of Mnr stimulates γ-secretase activity, while knockdown of Mnr inhibits this activity, demonstrating Mnr as a positive regulator of Notch signaling.

Summary: Loss of multiciliated cells is a common characteristic in chronic inflammatory airway diseases. Notch signaling plays a crucial role in controlling the proportion of multiciliated and secretory cells. Inhibition of Notch activation using a small molecule inhibitor can promote differentiation towards the multiciliated lineage. LY450139, a specific ?-secretase inhibitor, has shown potential in increasing multiciliated cell numbers without toxicity in both healthy and diseased lung cells, suggesting it as a promising therapeutic option to restore multiciliated cells and improve epithelial function in chronic lung diseases.

Summary: Gamma secretase inhibitors (GSIs), originally developed as Alzheimer's therapies, have been repurposed as anticancer agents due to their ability to inhibit Notch receptor cleavage. Despite showing promise in preclinical models, GSIs have not demonstrated significant clinical benefit in most solid tumors. Further research is needed to address limitations in understanding GSI mechanisms and improve their efficacy in cancer treatment.

Summary: Inhibition of Notch oncogenic signaling in humans leads to tumor regression and plays a role in intestinal homeostasis. A study in patients with refractory cancer treated with the first-in-human Notch inhibitor LY3039478 revealed abnormal intestinal epithelial cell differentiation and transient diarrhea as side effects, which resolved after discontinuing the drug. The findings confirm the importance of Notch signaling in maintaining intestinal homeostasis in humans.

Summary: PTEN plays an important role in regulating proliferation and osteogenic ability of dental pulp cells (hDPs), as well as inducing adipogenesis of adipose-derived mesenchymal stem cells (hADSCs). Inhibition of PTEN diminishes the proliferation and osteogenic potential of hDPs, and may compromise the adipogenic ability of hADSCs.
