Роль антиоксидантов в множестве миеломы: диагностика, прогнозирование и терапевтическое применение: обзор сюжета.

Множественная миэлома (ММ) — злокачественная клетка B-клеток с моноклональными плазменными клетками, производящими нефункциональные иммуноглобулины. Она по-прежнему неизлечима из-за de novo или приобретенного сопротивления злокачественных клеток стандартным химиотерапиям. Таким образом, понимание механизма терапевтического сопротивления имеет важнейшее значение для разработки более эффективных мер вмешательства и определения новых целей лечения. MM - это разнородная болезнь, характеризующаяся сложными генетическими изменениями, которые имеют решающее значение для прогнозирования стратификации.

Plants as a Source of Anticancer Agents: From Bench to Bedside.

Cancer is the second leading cause of death after cardiovascular diseases. Conventional anticancer therapies are associated with lack of selectivity and serious side effects. Cancer hallmarks are biological capabilities acquired by cancer cells during neoplastic transformation. Targeting multiple cancer hallmarks is a promising strategy to treat cancer. The diversity in chemical structure and the relatively low toxicity make plant-derived natural products a promising source for the development of new and more effective anticancer therapies that have the capacity to target multiple hallmarks in

Нетипичное участие белков Альцгеймера в болезнях, выходящих за рамки тауопатии.

Тау — микротубульский белок, традиционно связанный с коллективной группой расстройств, называемых «тауопатией», включая болезнь Альцгеймера. Протеин тау самоагрегирует и формирует нейрофибрилляторы в нейронах, которые считаются патоологической отличительной чертой тауопатии. Несмотря на то, что роль невралической тауопатии в тауопатии широко изучена, недавние исследования пролили свет на ее роль в других болезнях без тау-патологии и в других клетках. В настоящем обзоре мы намерены обсудить "типичное" патологическое участие тау в заболеваниях, отличных от тауопатии, включая заболевания головног

Amino acids metabolism: a potential target for cancer treatment.

Metabolic reprogramming of amino acids has been recognized as a significant characteristic in various types of cancers. Numerous studies have indicated that the metabolic reprogramming of amino acids in tumors significantly supports certain malignant behaviors, including tumor proliferation, survival, invasion, and even immune escape. Amino acids can provide biomolecules such as nucleotides and glutathione (GSH) for tumors, and the bioavailability of amino acids influences tumor progression. Meanwhile, as essential metabolites, amino acids are closely associated with immune cell activation and

Drug delivery for age-related bone diseases: From therapeutic targets to common and emerging therapeutic strategies.

With the accumulation of knowledge on aging, people have gradually realized that among the many factors that cause individual aging, the accumulation of aging cells is an essential cause of organ degeneration and, ultimately, age-related diseases. Most cells present in the bone microenvironment gradually age over time, leading to an imbalance of osteogenesis, osteoclastogenesis, adipogenesis, and chondrogenesis. This imbalance contributes to age-related bone loss and the development of age-related bone diseases, such as osteoporosis. Bone aging can prolong the lifespan and delay the developmen

Genomic profiling enables personalized strategies to overcome drug resistance in multiple myeloma.

Multiple myeloma (MM) is a hematologic malignancy characterized by the clonal proliferation of malignant plasma cells within the bone marrow. It is a complex and heterogeneous disease that primarily affects older adults and is associated with significant morbidity and mortality. Despite advances in treatment, including proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies, MM remains largely incurable, with most patients experiencing relapse and disease progression. The disease’s biological complexity is driven by a multitude of genetic and molecular alterations, which contr

Could Local Application of Hypoxia Inducible Factor 1-α Enhancer Deferoxamine Be Promising for Preventing of Medication-Related Osteonecrosis of the Jaw?

This experimental study investigates the prophylactic effect of deferoxamine (DFO) on medication-related osteonecrosis of the jaw (MRONJ). Thirty-six female Sprague Dawley rats received zoledronic acid (ZA) for eight weeks to create an osteonecrosis model. DFO was locally applied into the extraction sockets with gelatin sponge (GS) carriers to prevent MRONJ. The specimens were histopathologically and histomorphometrically evaluated. Hypoxia-inducible factor 1-alpha (HIF-1α) protein levels in the extraction sockets were quantified. New bone formation rate differed significantly between groups (

Blood Vessels and Peripheral Nerves as Key Players in Cancer Progression and Therapy Resistance.

Cancer cells continuously interact with the tumor microenvironment (TME), a heterogeneous milieu that surrounds the tumor mass and impinges on its phenotype. Among the components of the TME, blood vessels and peripheral nerves have been extensively studied in recent years for their prominent role in tumor development from tumor initiation. Cancer cells were shown to actively promote their own vascularization and innervation through the processes of angiogenesis and axonogenesis. Indeed, sprouting vessels and axons deliver several factors needed by cancer cells to survive and proliferate, inclu

Протекционный субъект PSMD1 является ключевой терапевтической целью в множестве миеломы.

Мы пришли к выводу, что PSMD1 - ключевой субъект протеиновой регуляционной частицы 19S - был чрезмерно экспрессирован и коррелировал с плохим прогнозом в множестве миеломы (ММ). Генетическое истощение PSMD1 снизило жизнеспособность раковых клеток, вызвало поликутилизированное накопление белка и способствовало апоптозу. Протеомический анализ показал активацию иммунных путей, что свидетельствует о потенциале иммунной модуляции. Нацеливание PSMD1 на незначительную поражающую РНК (SIRNA), доставляемую через липидные наночастицы (LNPs), уменьшило рост опухоли в линиях клеток MM и первичных проб пац

Targeting the proteasome in cancer therapy: development and future opportunities in natural products.

BACKGROUND: The ubiquitin-proteasome pathway is a critical therapeutic target in malignancies, particularly multiple myeloma. The development of proteasome inhibitors (PIs) has marked a milestone in multiple myeloma therapy and now constitutes the backbone of frontline treatment regimens. However, primary and acquired resistance remain a major challenge, underscoring the need to identify new PIs as well as agents that can resensitize resistant cells. METHOD: This review provides an overview of the current clinical applications of PIs and offers a comprehensive summary of natural products that

The Role of Cullin-RING Ligases in Striated Muscle Development, Function, and Disease.

The well-orchestrated turnover of proteins in cross-striated muscles is one of the fundamental processes required for muscle cell function and survival. Dysfunction of the intricate protein degradation machinery is often associated with development of cardiac and skeletal muscle myopathies. Most muscle proteins are degraded by the ubiquitin-proteasome system (UPS). The UPS involves a number of enzymes, including E3-ligases, which tightly control which protein substrates are marked for degradation by the proteasome. Recent data reveal that E3-ligases of the cullin family play more diverse and c

Endoplasmic reticulum stress in disease pathogenesis: its implications for therapy.

Endoplasmic reticulum (ER) stress is a key cellular mechanism that is important in the development of many diseases, including cancer. Since the discovery of the unfolded protein response (UPR), research has greatly improved our understanding of how ER stress affects cellular functions, especially protein folding and adaptation to stress. The UPR consists of three main branches: IRE1, ATF6, and PERK, each of which is crucial for regulating stress responses, protein homeostasis, and apoptosis. These pathways normally help cells handle stress effectively; however, excessive or prolonged activati

Cannabidiol on the Path from the Lab to the Cancer Patient: Opportunities and Challenges.

Cannabidiol (CBD), a major non-psychotropic component of cannabis, is receiving growing attention as a potential anticancer agent. CBD suppresses the development of cancer in both in vitro (cancer cell culture) and in vivo (xenografts in immunodeficient mice) models. For critical evaluation of the advances of CBD on its path from laboratory research to practical application, in this review, we wish to call the attention of scientists and clinicians to the following issues: (a) the biological effects of CBD in cancer and healthy cells; (b) the anticancer effects of CBD in animal models and clin

Targeting cancer stem cells in drug discovery: Current state and future perspectives.

In recent decades, cancer stem cells (CSCs) have been increasingly identified in many malignancies. CSC-related signaling pathways and their functions provide new strategies for treating cancer. The aberrant activation of related signaling pathways (e.g., Wnt, Notch, and Hedgehog pathways) has been linked to multiple types of malignant tumors, which makes these pathways attractive targets for cancer therapy. CSCs display many characteristic features, such as self-renewal, differentiation, high tumorigenicity, and drug resistance. Therefore, there is an urgent need to develop new therapeutic st

Cardio-Oncology Rehabilitation-Present and Future Perspectives.

Recent advances in cancer therapy have led to increased survival rates for cancer patients, but also allowed cardiovascular complications to become increasingly evident, with more than 40% of cancer deaths now being attributed to cardiovascular diseases. Cardiotoxicity is the most concerning cardiovascular complication, one caused mainly due to anti-cancer drugs. Among the harmful mechanisms of these drugs are DNA damage, endothelial dysfunction, and oxidative stress. Cancer patients can suffer reduced cardiorespiratory fitness as a secondary effect of anti-cancer therapies, tumor burden, and

Sphingolipid metabolism and hematologic disorders: current understanding and future directions.

Sphingolipids are not only key structural components of cell membranes but also serve as important signaling molecules, and their metabolic homeostasis is essential for the maintenance of cellular functions. In recent years, with the advancement of technologies such as metabolomics, studies have revealed that sphingolipid metabolic abnormalities are extensively involved in the occurrence and development of various hematological disorders, including immune thrombocytopenia, myeloproliferative neoplasms, graft-versus-host disease, hereditary hematological diseases, and hematologic malignancies.

Метаболомическое исследование синдромов миэлодипластика, множественной миеломы и гомозиговой β-Талассемии.

Хроническая анемия, как правило, диагностируется у пожилых людей и служит важным показателем как реактивных, так и клональных заболеваний. Многие основные заболевания, такие, как миэллодипластические синдромы и множественная миелома, более распространены среди пожилых людей, в то время как новые терапевтические подходы превратили педиатрические расстройства слабого прогноза, такие, как бета-талассемия, в хроническое заболевание пожилых людей. Таким образом, растущая распространенность хронической анемии в пожилом возрасте в значительной степени объясняется более частыми диагностическими и тера
