Advanced multifunctional thermo- and electro-stimulative hydrogels for bone regeneration.

Bone defects caused by trauma, infection, tumors, osteoporosis, and diabetes disrupt skeletal integrity and impair regeneration. The healing process involves inflammatory hematoma formation, callus development, and remodeling, coordinated by diverse cells and signaling pathways. Conventional grafts and inorganic implants are limited by donor scarcity, immune rejection, and low bioactivity, necessitating more effective repair strategies. Recently, multifunctional smart hydrogels have emerged as a frontier in bone regeneration due to their biocompatibility, tunable structure, and ability to inte

Vision of Life's Code: Molecular Probe Nanoarchitectonics for Deep RNA/DNA Illumination.

Visualization of RNA and DNA provides a window of opportunity for the early detection of multiple diseases and approaches to manipulate them before any pathological processes occur. However, current imaging systems often fail to meet these demands due to the need for multiple RNA and DNA chemical probes, which increases experimental complexity, reduces awareness of false positives, and limits imaging accuracy in complex biosystems. In this work, we identify the key challenges associated with using multiple probes for RNA and DNA imaging and analyze the mechanisms and performance of existing im

Адипоцитный β-гидроксибутират обеспечивает метаболическую стойкость в множестве миеломы.

Множественная миелома (ММ) остается неизлечимым раком крови. Ожирение является известным фактором риска, но то, как адипоциты способствуют прогрессу MM, не в полной мере понятно. Здесь мы обнаруживаем метаболический перекресток между адипоцитами и клетками MM, который способствует выживанию клеток MM под глюкозой. Мы показываем, что ограничение глюкозы активирует АМПК, срывает связь HSP90-IRF4 и делает IRF4 восприимчивым к протеасомной деградации при помощи TRIM21. Парадоксально, но такой же стресс стимулирует адипоциты к производству β-гидроксибутирата (β-OHB). Клетки MM используют β-OHB при

Cancer Cell Metabolism in Hypoxia: Role of HIF-1 as Key Regulator and Therapeutic Target.

In order to meet the high energy demand, a metabolic reprogramming occurs in cancer cells. Its role is crucial in promoting tumor survival. Among the substrates in demand, oxygen is fundamental for bioenergetics. Nevertheless, tumor microenvironment is frequently characterized by low-oxygen conditions. Hypoxia-inducible factor 1 (HIF-1) is a pivotal modulator of the metabolic reprogramming which takes place in hypoxic cancer cells. In the hub of cellular bioenergetics, mitochondria are key players in regulating cellular energy. Therefore, a close crosstalk between mitochondria and HIF-1 underl

T-Regulatory Cells In Tumor Progression And Therapy.

Regulatory T cells (Tregs) are important members of the immune system regulating the host responses to infection and neoplasms. Tregs prevent autoimmune disorders by protecting the host-cells from an immune response, related to the peripheral tolerance. However, tumor cells use Tregs as a shield to protect themselves against anti-tumor immune response. Thus, Tregs are a hurdle in achieving the complete potential of anti-cancer therapies including immunotherapy. This has prompted the development of novel adjuvant therapies that obviate their negative effects thereby enhancing the therapeutic ef

Established and Emerging Concepts to Treat Imbalances of Iron Homeostasis in Inflammatory Diseases.

Inflammation, being a hallmark of many chronic diseases, including cancer, inflammatory bowel disease, rheumatoid arthritis, and chronic kidney disease, negatively affects iron homeostasis, leading to iron retention in macrophages of the mononuclear phagocyte system. Functional iron deficiency is the consequence, leading to anemia of inflammation (AI). Iron deficiency, regardless of anemia, has a detrimental impact on quality of life so that treatment is warranted. Therapeutic strategies include (1) resolution of the underlying disease, (2) iron supplementation, and (3) iron redistribution str

Noncanonical SQSTM1/p62-Nrf2 pathway activation mediates proteasome inhibitor resistance in multiple myeloma cells via redox, metabolic and translational reprogramming.

Multiple Myeloma (MM) is a B-cell malignancy characterized by the accumulation of clonal plasma cells in the bone marrow, with drug resistance being a major cause of therapeutic failure. We established a carfilzomib-resistant derivative of the LP-1 MM cell line (LP-1/Cfz) and found that the transcription factor NF-E2 p45-related factor 2 (Nrf2; gene symbol NFE2L2) contributes to carfilzomib resistance. The mechanism of Nrf2 activation involved enhanced translation of Nrf2 as well as its positive regulator, the autophagy receptor sequestosome 1 (SQSTM1)/p62. The eukaryotic translation initiatio

Breaking the Resistance: Photodynamic Therapy in Cancer Stem Cell-Driven Tumorigenesis.

Cancer stem cells (CSCs) are essential for the growth of malignancies because they encourage resistance to cancer therapy and make metastasis and relapse easier. To effectively tackle the obstacles presented by CSCs, novel therapeutic approaches are required. Photodynamic therapy (PDT) is a promising treatment option for cancer cells, which uses light-sensitive medications that are activated by light wavelengths. This review investigates the use of PDT to overcome malignancies driven by CSCs that have innate resistance mechanisms. PDT works by causing tumor cells to accumulate photosensitizers

Rejuvenation Strategy for Inducing and Enhancing Autoimmune Response to Eliminate Senescent Cells.

The process of aging, which involves progressive changes in the body over time, is closely associated with the development of age-related diseases. Cellular senescence is a pivotal hallmark and mechanism of the aging process. The accumulation of senescent cells can significantly contribute to the onset of age-related diseases, thereby compromising overall health. Conversely, the elimination of senescent cells enhances the body's regenerative and reparative capacity, thereby retarding the aging process. Here, we present a brief overview of 12 Hallmarks of aging and subsequently emphasize the po

Fasting-Mimicking Diet Is Safe and Reshapes Metabolism and Antitumor Immunity in Patients with Cancer.

In tumor-bearing mice, cyclic fasting or fasting-mimicking diets (FMD) enhance the activity of antineoplastic treatments by modulating systemic metabolism and boosting antitumor immunity. Here we conducted a clinical trial to investigate the safety and biological effects of cyclic, five-day FMD in combination with standard antitumor therapies. In 101 patients, the FMD was safe, feasible, and resulted in a consistent decrease of blood glucose and growth factor concentration, thus recapitulating metabolic changes that mediate fasting/FMD anticancer effects in preclinical experiments.

Exploring the Impact of the Obesity Paradox on Lung Cancer and Other Malignancies.

There is a paradoxical relationship between obesity, as measured by BMI, and many types of cancer, including non-small-cell lung cancer. Obese non-small-cell lung cancer patients have been shown to fare better than their non-obese counterparts. To analyze the multifaceted effects of obesity on oncologic outcomes, we reviewed the literature on the obesity paradox, methods to measure adiposity, the obesity-related derangements in immunology and metabolism, and the oncologic impact of confounding variables such as gender, smoking, and concomitant medications such as statins and metformin.

Cachexia as Evidence of the Mechanisms of Resistance and Tolerance during the Evolution of Cancer Disease.

During its evolution, cancer induces changes in patients' energy metabolism that strongly affect the overall clinical state and are responsible for cancer-related cachexia syndrome. To better understand the mechanisms underlying cachexia and its metabolic derangements, research efforts should focus on the events that are driven by the immune system activation during the evolution of neoplastic disease and on the phenomena of "resistance" and "tolerance" typically involved in the human body response against stress, pathogens, or cancer. Indeed, in the case where resistance is not able to elimin

The Potential of Chronotherapy and Nanotherapy-Based Strategies for Glioblastoma Treatment.

Glioblastoma is the most common and aggressive brain tumour in adults, and despite ongoing efforts, effective treatment remains limited. Standard therapies often face challenges because of the tumour's specific biology, its aggressive nature, and the presence of certain physiological barriers in the brain that impede chemotherapeutics from reaching their target. Emerging research in circadian biology highlights the role of the internal circadian clock in tumour progression and treatment response. Evidence suggests that aligning therapy to patients' chronotypes could potentially improve treatme

Sodium-glucose cotransporter 2 inhibitors and the cancer patient: from diabetes to cardioprotection and beyond.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i), a new drug class initially designed and approved for treatment of diabetes mellitus, have been shown to exert pleiotropic metabolic and direct cardioprotective and nephroprotective effects that extend beyond their glucose-lowering action. These properties prompted their use in two frequently intertwined conditions, heart failure and chronic kidney disease.

Ferroptosis in Haematological Malignancies and Associated Therapeutic Nanotechnologies.

Haematological malignancies are heterogeneous groups of cancers of the bone marrow, blood or lymph nodes, and while therapeutic advances have greatly improved the lifespan and quality of life of those afflicted, many of these cancers remain incurable. The iron-dependent, lipid oxidation-mediated form of cell death, ferroptosis, has emerged as a promising pathway to induce cancer cell death, particularly in those malignancies that are resistant to traditional apoptosis-inducing therapies. Although promising findings have been published in several solid and haematological malignancies, the major
