Strategies to Improve Sensitivity to Radiotherapy in Pediatric Solid Tumors.

The primary goal in the treatment of pediatric malignancies is to maintain effective cancer control while minimizing toxicities and late effects. Radiotherapy is a component of standard therapy against many pediatric cancers, but tumor cell DNA damage repair mechanisms and the hypoxic tumor microenvironment may limit the effectiveness of this modality. Additionally, irradiated cancer cells often acquire resistance to radiotherapy that permits cancer cell survival or stimulates tumor regrowth after treatment, further limiting the efficacy of radiotherapy. Various preclinical studies have invest

Reporting of surrogate endpoints in randomised controlled trial reports (CONSORT-Surrogate): extension checklist with explanation and elaboration.

Randomised controlled trials commonly use surrogate endpoints to substitute for a target outcome (outcome of direct interest and relevance to trial participants, clinicians, and other stakeholders—eg, all cause mortality) to improve their efficiency (through shorter trial duration, reduced sample size, and thus lower research costs), or for ethical or practical reasons. But reliance on surrogate endpoints can increase the uncertainty of an intervention’s treatment effect and potential failure to provide adequate information on intervention harms, which has led to calls for improved reporting o

Inflammatory bone marrow microenvironment impairs the therapeutic effect of daratumumab-lenalidomide in multiple myeloma.

Daratumumab-lenalidomide (DR) combination therapy improves multiple myeloma (MM) outcomes, yet some patients respond poorly. We examined 21 DR pre-treatment samples from the IFM2017-03 phase 3 trial using single-cell and bulk multiomics approaches to identify determinants of response. Analysis of the bone marrow environment revealed a coordinated inflammatory state across immune and myeloma cells associated with DR resistance. We identified upregulated NF-κB signaling genes in monocytes of non-responders, alongside increased proinflammatory ISG + T cells and attenuated NK cell CD16 expression,

Биоразлагаемый электроспун PLGA Nanofibers-Encapsolated Trichinella Sphiralis Antigens защищает от повторного использования экспериментального аутоиммунного энцефаломилита и связанного с ним микробиота дисбиоз.

ЦЕЛЬ: " Тричинелла спиралис " создала сложные механизмы иммуномодуляции при посредничестве экскременто-секретарских продуктов (ESL1), которые позволяют ей выжить в принимающей стране. Следовательно, антигены ESL1 обладают прекрасным потенциалом для лечения аутоиммунных заболеваний, таких, как множественный склероз (MS). Однако вопрос о том, могут ли своевременные контролируемые поставки антигенов ESL1 в vivo, как и в случае естественных инфекций, повысить его терапевтический потенциал в отношении MS, до сих пор неизвестен.Для этого мы ввели антигены ESL1 в полихлорированные (лактидно

CK1α/RUNX2 Axis in the Bone Marrow Microenvironment: A Novel Therapeutic Target in Multiple Myeloma.

Multiple myeloma (MM) is a malignant plasma cell (PC) neoplasm, which also displays pathological bone involvement. Clonal expansion of MM cells in the bone marrow causes a perturbation of bone homeostasis that culminates in MM-associated bone disease (MMABD). We previously demonstrated that the S/T kinase CK1α sustains MM cell survival through the activation of AKT and β-catenin signaling. CK1α is a negative regulator of the Wnt/β-catenin cascade, the activation of which promotes osteogenesis by directly stimulating the expression of RUNX2, the master gene regulator of osteoblastogenesis. In t

Lipid nanoparticle-mediated mRNA/siRNA dual-bioengineered dendritic cell vaccines combined of PD-1/PD-L1 blockade for boosting tumor immunotherapy.

DC vaccines occupy a pivotal position in the realm of cancer treatment, leveraging the immune system to precisely target and effectively eliminate tumor cells. However, current challenges in tumor DC vaccine development include issues such as limited efficacy and potential upregulation of immunosuppressive molecules like PD-L1 on tumor cells. Herein, we employed microfluidic technology to fabricate lipid nanoparticles (LNPs) that simultaneously encapsulate OVA mRNA (mOVA), encoding the model antigen OVA, and siRNA targeting PD-L1. The LNP/mOVA/siPD-L1 nanoparticles were utilized to transfect b

Paraneoplastic Neurological Syndromes: Advances and Future Perspectives in Immunopathogenesis and Management.

Paraneoplastic neurological syndromes (PNSs) are immune-mediated disorders caused by an antitumor response that cross-reacts with the nervous system, leading to severe and often irreversible neurological disability. Once considered exceedingly rare, PNSs are now increasingly recognized owing to the identification of novel neural autoantibodies, wider use of commercial testing, and the emergence of immune checkpoint inhibitor (ICI)-related neurotoxicity that phenotypically overlaps with classic PNS. In this narrative review, we performed a structured search of PubMed/MEDLINE, Scopus, Web of Sci

Neutrophil extracellular traps in homeostasis and disease.

Neutrophil extracellular traps (NETs), crucial in immune defense mechanisms, are renowned for their propensity to expel decondensed chromatin embedded with inflammatory proteins. Our comprehension of NETs in pathogen clearance, immune regulation and disease pathogenesis, has grown significantly in recent years. NETs are not only pivotal in the context of infections but also exhibit significant involvement in sterile inflammation. Evidence suggests that excessive accumulation of NETs can result in vessel occlusion, tissue damage, and prolonged inflammatory responses, thereby contributing to the

Harnessing CAR-Extracellular Vesicles for Next-Generation Cancer Immunotherapy.

Cancer immunotherapy has experienced substantial progress in recent years, particularly with the advancement of chimeric antigen receptor (CAR) technology, which enables immune cells to selectively target tumor-associated antigens. CARs, now in their fifth generation, are engineered by combining monoclonal antibody fragments with signaling and co-stimulatory domains and have been successfully applied to T cell, natural killer (NK) cell, and macrophage-based therapies. Notable clinical successes, such as tisagenlecleucel and lisocabtagene maraleucel underscore the therapeutic potential of CAR-T

Ancient genes establish stress-induced mutation as a hallmark of cancer.

Cancer is sometimes depicted as a reversion to single cell behavior in cells adapted to live in a multicellular assembly. If this is the case, one would expect that mutation in cancer disrupts functional mechanisms that suppress cell-level traits detrimental to multicellularity. Such mechanisms should have evolved with or after the emergence of multicellularity. This leads to two related, but distinct hypotheses: 1) Somatic mutations in cancer will occur in genes that are younger than the emergence of multicellularity (1000 million years [MY]); and 2) genes that are frequently mutated in cance

Baseline Characteristics of Participants in the Exercise for Cancer to Enhance Living Well (EXCEL) Study: A Canada-Wide Rural-Urban Analysis.

IntroductionExercise interventions improve quality of life and survival for individuals living with and beyond cancer (ILWBC), yet equitable access remains limited. Evidence on characteristics of who enrolls in exercise oncology programs is scarce, leaving gaps for equity-focused recruitment and scale-up, particularly in rural and underserved settings. The EXercise for Cancer to Enhance Living Well (EXCEL) study offers a unique opportunity to examine these issues across a Canada-wide cohort.MethodsEXCEL is an 8-12-week tailored exercise intervention delivered primarily to ILWBC in rural/remote

Therapeutic potential of cytokine-induced killer cell therapy for renal cell carcinoma and prostate cancer.

Renal cell carcinoma (RCC) and prostate cancer (PCa) are among the most prevalent and therapeutically challenging malignancies of the genitourinary system, particularly in advanced or metastatic stages. For advanced/metastatic RCC, targeted agents such as tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) have improved progression-free and overall survival. For metastatic castration-sensitive PCa, androgen deprivation therapy (ADT) combined androgen receptor pathway inhibitors (ARPIs) with or without chemotherapy remains the standard of care. Despite these advances, ther

Update on current pancreatic treatments: from molecular pathways to treatment.

Pancreatic cancer is still diagnosed at a late stage although we have novel diagnostic tools. Pancreatic cancer chemotherapy treatment resistance is observed and therefore novel treatments are in need. Anti-cancer stem cell therapy, combination of chemotherapy and/or radiotherapy with immunotherapy, proteins/enzymes and gene therapy are currently under evaluation. Targeted treatment with tyrosine kinase inhibitors is also administered and novel inhibitors are also under evaluation. In the current review we present recent data from our search within the year 2018.

Clinical management and therapeutic development for the rare disease rhabdomyosarcoma.

Rhabdomyosarcoma (RMS) is a rare disease that arises from skeletal muscle mainly affects children and adolescents. Patients with RMS have diverse symptoms and prognosis based on tumor sizes, tumor anatomical locations, histological subtypes of the tumors and genetic testing of paired-box-forkhead box O1 (PAX-FOXO1) fusion gene. The 4 subtypes of RMS include embryonal RMS (eRMS), alveolar RMS (aRMS), spindle cell/sclerosing RMS (scRMS) and pleomorphic RMS (pRMS). Treatment for RMS patients remains challenging due to its heterogeneous nature. Thus, a combinatory approach is likely to warrant bet
