Head and neck cancer (HNC) is a highly aggressive type of tumor characterized by delayed diagnosis, recurrence, metastasis, relapse, drug resistance. The occurrence HNC were associated with smoking, alcohol abuse (or both), human papillomavirus infection, complex genetic epigenetic predisposition. Currently, surgery radiotherapy are the standard treatments for most patients early-stage HNC. For recurrent or metastatic (R/M) HNC, first-line treatment platinum-based chemotherapy combined antiepidermal growth factor receptor cetuximab, when resurgery radiation therapy not an option. However, curing remains challenging, especially in cases metastasis. In this review, we summarize pathogenesis including changes, abnormal signaling pathways, immune regulation mechanisms, along all potential therapeutic strategies such as molecular targeted therapy, immunotherapy, gene modifications, combination therapies. Recent preclinical clinical studies that may offer future research on also discussed. Additionally, new targets methods, antibody-drug conjugates, photodynamic radionuclide mRNA vaccines, have shown promising results trials, offering prospects

Background: Acute myeloid leukemia (AML) is a heterogeneous disease highly resistant to chemotherapeutic agents. Leukemia stem cells (LSCs) can enter dormant state and avoid apoptosis in the protective niche of bone marrow (BM) microenvironment. Moreover, stromal protect by promoting pro-survival signaling pathways drug resistance. Therefore, attenuating interactions between BM may have positive therapeutic effect. Objectives: In this work, we hypothesized that sondages inhibit adhesion inhibiting Hedgehog (Hh) pathway. The pathway key target AML due its role leukemic cell growth survival. Methods: We investigated effects sonidegib on individual OCI-AML3 spheroid derived from HS-5 line. For purpose, precisely determined minimum cell-to-cell time using optical tweezers under normoxic (21% O2) hypoxic (1% conditions. Results: Our results demonstrated significantly increased necessary for establish adhesive bonds with cells, thereby indicating reduction their properties. Additionally, showed particularly effective at oxygen concentrations. Conclusions: obtained study suggest sonidegib, through modulation pathway, holds promise as potential approach within

Abstract The gut microbiota has been demonstrated to be correlated with the clinical phenotypes of diseases, including cancers. However, there are few studies on subtyping based microbiota, especially in breast cancer (BC) patients. Here, using machine learning methods, we analysed BC, colorectal (CRC), and gastric (GC) patients identify their shared metabolic pathways importance these development. Based microbiota-related pathways, human gene expression profile patient prognosis, established a novel BC system identified subtype called “challenging BC”. Tumours this have more genetic mutations complex immune environment than those other subtypes. A score index was proposed for in-depth analysis showed significant negative correlation prognosis.
