Advances in improving cancer immunotherapy with nanotechnology: from smart nanoparticles to synergistic combination strategies.

Cancer immunotherapy has substantially advanced cancer treatment, achieving durable responses in select malignancies. However, its widespread application is limited by significant challenges: low efficacy in many solid tumors, severe side effects, and immune evasion facilitated by the tumor microenvironment (TME). Nanotechnology offers a promising approach to address these obstacles. By employing nanoparticles (NPs), we can precisely deliver therapeutics to tumor sites, ensure controlled release to minimize side effects, and amplify the immune response, thereby substantially boosting the effec

Exploiting Nanomedicine for Cancer Polychemotherapy: Recent Advances and Clinical Applications.

The most important limitations of chemotherapeutic agents are severe side effects and the development of multi-drug resistance. Recently, the clinical successes achieved with immunotherapy have revolutionized the treatment of several advanced-stage malignancies, but most patients do not respond and many of them develop immune-related adverse events. Loading synergistic combinations of different anti-tumor drugs in nanocarriers may enhance their efficacy and reduce life-threatening toxicities. Thereafter, nanomedicines may synergize with pharmacological, immunological, and physical combined tre

Risk Stratification Before and During Treatment in Newly Diagnosed Multiple Myeloma: From Clinical Trials to the Real-World Setting.

Multiple Myeloma (MM) is a hematologic malignancy characterized by a wide clinical and biological heterogeneity leading to different patient outcomes. Various prognostic tools to stratify newly diagnosed (ND)MM patients into different risk groups have been proposed. At baseline, the standard-of-care prognostic score is the Revised International Staging System (R-ISS), which stratifies patients according to widely available serum markers (i.e., albumin, β 2-microglobulin, lactate dehydrogenase) and high-risk cytogenetic abnormalities detected by fluorescence in situ hybridization. Though this s

Genetic hallmarks and clinical implications of chromothripsis in childhood T-cell acute lymphoblastic leukemia.

Chromothripsis (cth) is a form of genomic instability leading to massive de novo structural chromosome rearrangements in a one-time catastrophic event. It can cause cancer-promoting alterations, such as loss of sequences for tumor-suppressor genes, formation of oncogenic fusions, and oncogene amplifications. We investigated the genetic background and clinical significance of cth in childhood T-cell acute lymphoblastic leukemia (T-ALL) patients. For this purpose, whole-genome copy number alterations were analyzed in 173 children with newly diagnosed T-ALL using high-density microarrays. Cth was

The molecular make up of smoldering myeloma highlights the evolutionary pathways leading to multiple myeloma.

Smoldering myeloma (SMM) is associated with a high-risk of progression to myeloma (MM). We report the results of a study of 82 patients with both targeted sequencing that included a capture of the immunoglobulin and MYC regions. By comparing these results to newly diagnosed myeloma (MM) we show fewer NRAS and FAM46C mutations together with fewer adverse translocations, del(1p), del(14q), del(16q), and del(17p) in SMM consistent with their role as drivers of the transition to MM. KRAS mutations are associated with a shorter time to progression (HR 3.5 (1.5-8.1), p = 0.001). In an analysis of ch

The Advent of Molecular Targeted Therapies Against Cancer. Toward Multi-Targeting Drugs Through Materials Engineering: A Possible Future Scenario.

The authors, actively engaged in the development of mesoporous silica-based solutions, initially for modified drug release, later for the smart administration of conventional chemotherapeutic cytotoxic drugs, present the evolution of the concept of targeted therapy across different disciplines. They also discuss the diverse therapeutic needs and related challenges (adverse drug effects) that have unfolded over the last 30 years. Nanomedicine potentialities, mainly against cancers, that have emerged globally during the intense research activity of the last few decades, are critically discussed.

Связанный с воспалением IncRNA вызывает нейронные повреждения в результате митохондриальной дисфункции.

В качестве ключевых факторов в регулировании генов появляются некодирующие SNP, которые часто находят свое отражение в специфических для тканей регулятивных элементах. Среди этих элементов длинные некодирующие РНК (lncRNA) участвуют во многих клеточных процессах, и их характеристики делают эти молекулы привлекательными для терапевтических целей. В этом исследовании мы изучили IncRNA LOC339803 в контексте нейронных клеток, которые расположены в районе 2p15, связанном с автоиммунитетом, и недавно описываем, что они играют провоспалительную роль в кишечных расстройствах.

Mechanisms of IFNalpha-1a-Induced Apoptosis in a Laryngeal Cancer Cell Line.

BACKGROUND Interferon alpha (IFNalpha) exerts its anti-proliferative effect on many human cancers. Among the 13 subtypes of human IFNalpha, IFNalpha-1 subtype has 2 variants, named IFNalpha-1a and IFNalpha-1b, that differ from each other in only 1 amino acid, at residue 114. However, the mechanism by which IFNalpha-1a mediates growth inhibition is still unclear. MATERIAL AND METHODS Human laryngeal carcinoma HEp2 cells were treated with IFNalpha-1a by either transient transfection or exogenous delivery. Western blot and RT-PCR analysis were carried out to assess apoptotic pathways active in IF

Recent Review on Biological Barriers and Host-Material Interfaces in Precision Drug Delivery: Advancement in Biomaterial Engineering for Better Treatment Therapies.

Preclinical and clinical studies have demonstrated that precision therapy has a broad variety of treatment applications, making it an interesting research topic with exciting potential in numerous sectors. However, major obstacles, such as inefficient and unsafe delivery systems and severe side effects, have impeded the widespread use of precision medicine. The purpose of drug delivery systems (DDSs) is to regulate the time and place of drug release and action. They aid in enhancing the equilibrium between medicinal efficacy on target and hazardous side effects off target. One promising approa

Engineered mesenchymal stem cell-derived exosomes: A revolutionary approach to unlocking liver disease treatment.

Exosomes, a specific type of extracellular vesicle with diameters ranging from 30 to 150 nm, play a vital role in coordinating various physiological and pathological processes through direct cell-to-cell communication. These vesicles transport a diverse range of molecules, including proteins, mRNAs, miRNAs, and lipids, that originate from parent cells. Exosomes are released by nearly all cell types, including mesenchymal stem cells (MSCs), and possess significant potential due to their regenerative and immunomodulatory properties. In the context of liver disease treatment, these capabilities o

Engineering precision nanoparticles for drug delivery.

In recent years, the development of nanoparticles has expanded into a broad range of clinical applications. Nanoparticles have been developed to overcome the limitations of free therapeutics and navigate biological barriers - systemic, microenvironmental and cellular - that are heterogeneous across patient populations and diseases. Overcoming this patient heterogeneity has also been accomplished through precision therapeutics, in which personalized interventions have enhanced therapeutic efficacy. However, nanoparticle development continues to focus on optimizing delivery platforms with a one-

NKG2D-CAR-transduced natural killer cells efficiently target multiple myeloma.

CAR-T-cell therapy against MM currently shows promising results, but usually with serious toxicities. CAR-NK cells may exert less toxicity when redirected against resistant myeloma cells. CARs can be designed through the use of receptors, such as NKG2D, which recognizes a wide range of ligands to provide broad target specificity. Here, we test this approach by analyzing the antitumor activity of activated and expanded NK cells (NKAE) and CD45RA- T cells from MM patients that were engineered to express an NKG2D-based CAR. NKAE cells were cultured with irradiated Clone9.mbIL21 cells. Then, cells

Plasma microRNA profiles: identification of miR-25 as a novel diagnostic and monitoring biomarker in oesophageal squamous cell carcinoma.

Molecular Mechanisms of Bortezomib Action: Novel Evidence for the miRNA-mRNA Interaction Involvement.

Bortezomib is an anti-tumor agent, which inhibits 26S proteasome degrading ubiquitinated proteins. While apoptotic transcription-associated activation in response to bortezomib has been suggested, mechanisms related to its influence on post-transcriptional gene silencing mediated regulation by non-coding RNAs remain not fully elucidated. In the present study, we examined changes in global gene and miRNA expression and analyzed the identified miRNA-mRNA interactions after bortezomib exposure in human neuroblastoma cells to define pathways affected by this agent in this type of cells.

Role of Telomeres and Telomeric Proteins in Human Malignancies and Their Therapeutic Potential.

Telomeres are the ends of linear chromosomes comprised of repetitive nucleotide sequences in humans. Telomeres preserve chromosomal stability and genomic integrity. Telomere length shortens with every cell division in somatic cells, eventually resulting in replicative senescence once telomere length becomes critically short. Telomere shortening can be overcome by telomerase enzyme activity that is undetectable in somatic cells, while being active in germline cells, stem cells, and immune cells. Telomeres are bound by a shelterin complex that regulates telomere lengthening as well as protects t

Фульминантный внематочный рецидив множественной миэломы с редким сердцем, сосудистым и многовизорным участием: отчет о деле.

Множественная миелома (ММ) — плазменная злокачественная клетка, которая, как правило, проходит длительный клинический курс. Внешняя болезнь (ЭМД) представляет собой агрессивное проявление MM с относительно низким уровнем заболеваемости, которое традиционно затрагивает кожу и мягкие ткани. В то время как MM, как правило, безжалостно прогрессирует, мощное развитие болезней, характеризующееся обширной многовизорной и сосудистой инфильтрацией, является исключительно редким явлением и редко документируется в медицинской литературе. Этот случай иллюстрирует 64-летнюю женщину, у которой были обнаруже
