Ginsenoside-Mediated Ferroptosis Regulation: Bidirectional Effects and Therapeutic Potential in Diseases.

Notably, certain ginsenoside components exhibit distinct bidirectional and context-dependent regulatory effects on ferroptosis depending on the disease setting. In aberrantly proliferating or activated cells, ginsenosides function as ferroptosis inducers, whereas in damaged quiescent cells of normal tissues, they act as ferroptosis inhibitors. The pro-ferroptotic effect is predominantly observed in cells characterized by abnormal proliferation or activation, such as cancer cells and activated hepatic stellate cells in liver fibrosis. In this context, ginsenosides modulate key iron metabolism p

Endothelial dysfunction and hemostatic imbalance in CAR T-cell-associated toxicities: pathophysiological insights and the role of circulating biomarkers.

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment of relapsed or refractory hematologic malignancies. While its clinical efficacy is well established, CAR T-cell therapy is frequently associated with severe immune-mediated toxicities, including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), coagulopathy, and hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS). Increasing evidence suggests that endothelial dysfunction, hemostatic imbalance, and complement activation are key contributors to the pathogenesis of

Hepatocellular Carcinoma: Old and Emerging Therapeutic Targets.

Liver cancer, predominantly hepatocellular carcinoma (HCC), globally ranks sixth in incidence and third in cancer-related deaths. HCC risk factors include non-viral hepatitis, alcohol abuse, environmental exposures, and genetic factors. No specific genetic alterations are unequivocally linked to HCC tumorigenesis. Current standard therapies include surgical options, systemic chemotherapy, and kinase inhibitors, like sorafenib and regorafenib. Immunotherapy, targeting immune checkpoints, represents a promising avenue. FDA-approved checkpoint inhibitors, such as atezolizumab and pembrolizumab, s

The critical role of γ-secretase and its inhibitors in cancer and cancer therapeutics.

As a multi-substrate transmembrane protease, γ-secretase exists widely in various cells. It controls multiple important cellular activities through substrate cleavage. γ-secretase inhibitors (GSIs) play a role in cancer inhibition by blocking Notch cleavage, and are considered as potential therapeutic strategies for cancer. Currently, GSIs have encouraging performance in preclinical models, yet this success does not translate well in clinical trials. In recent years, a number of breakthrough discoveries have shown us the promise of targeting γ-secretase for the treatment of cancer. Here, we in

Local administration of mesenchymal stromal cells is safe and modulates the immune compartment in ulcerative proctitis.

BACKGROUNDDue to their immunoregulatory and tissue regenerative features, mesenchymal stromal cells (MSCs) are a promising novel tool for the management of ulcerative proctitis (UP). Here we report on a phase IIa clinical study that evaluated the impact of local MSC therapy on UP.METHODSThirteen refractory UP patients, with an endoscopic Mayo score (EMS) of 2 or 3, were included. Seven patients received 20-40 million allogeneic MSCs (cohort 1), while 6 patients received 40-80 million MSCs (cohort 2). Adverse events (AEs) were assessed at baseline and on weeks 2, 6, 12, and 24. Clinical, endosc

Resveratrol and clinical trials: the crossroad from in vitro studies to human evidence.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a non-flavonoid polyphenol that may be present in a limited number of foodstuffs such as grapes and red wine. Resveratrol has been reported to exert a plethora of health benefits through many different mechanisms of action. This versatility and presence in the human diet have drawn the worldwide attention of many research groups over the past twenty years, which has resulted in a huge output of in vitro and animal (preclinical) studies. In line with this expectation, many resveratrol- based nutraceuticals are consumed all over the world with qu

Кинуреньенс и митохондриальные расстройства в многоразовом склерозе.

Множественный склероз (MS) — хроническое аутоиммунное заболевание, характеризующееся воспалением, обезвоживанием и нейродегенерацией в центральной нервной системе. Патогенез MS связан с иммунной атаки на миелин и нейроны, сопровождаемой дисфункцией мозга в крови и хроническим воспалением CNS. Центральное значение для патологии MS имеет дисрегулирование кинуреньинового пути, который метаболизирует триптофан в нейроактивные соединения. Активация Kynurenin Translation (KP) под воздействием подстрекательских цитокинов приводит к образованию как нейрозащитных (например, кинуриновой кислоты, КИНА),

Синергистические механизмы традиционной китайской медицины и протеиновых ингибаторов в многократной терапии миеломы: всеобъемлющий обзор.

Множественная миелома (ММ) — клональная плазменная порча клеток, характеризующаяся инфильтрацией костного мозга, производством моноклонального иммуноглобулина и многосистемным повреждением. Протеозные ингибиторы (ИП), такие, как бортезомиб, карфилзомиб и иксазомиб, значительно улучшили без прогрессии и общее выживание пациентов с ОМ. Однако резистентность к лекарственным препаратам и неблагоприятные последствия, включая периферическую нейропатию и кардиотоксичность, по-прежнему являются основными ограничениями для долгосрочного контроля за заболеваниями. Цель настоящего обзора заключается в вс

Освещение нанотерапевтики с точными глазами: от оптического к радионаностантике.

Рак по-прежнему относится к числу самых смертоносных заболеваний во всем мире, унося много жизней из-за высоких показателей смертности. Химиотерапия, являющаяся одной из основных форм лечения рака, приносит значительные выгоды, однако ей мешают недостатки, которые ставят под угрозу качество жизни пациентов. Таким образом, разработка альтернатив минимально инвазивному лечению по-прежнему представляет собой серьезную проблему. Среди них наноматериалы, легкая фототерапия, включая фотодинамическую терапию, фототермальную терапию и радиотерапию, являются перспективными вариантами, обеспечивающими т

Associations between acute and chronic graft-versus-host disease.

AbstractChronic graft-versus-host disease (GVHD) is 1 of the major complications after allogeneic hematopoietic cell transplantation (allo-HCT). Although various risk factors for chronic GVHD have been reported, limited data are available regarding the impact of acute GVHD on chronic GVHD. We examined the association between acute and chronic GVHD using a Japanese registry data set. The landmark point was set at day 100 after allo-HCT, and patients who died or relapsed before the landmark point were excluded. In total, 14 618 and 6135 patients who underwent allo-HCT with bone marrow or periphe

PI3K/AKT сигнализирующий путь: молекулярный перекресток в опухоли и терапевтические инновации.

PI3K/AKT сигнализирующий путь служит центральным регулирующим узлом, регулирующим основные клеточные процессы, включая рост, распространение, метаболизм, выживание и миграцию. В контексте развития опухоли и рака аберральная активация этого пути приводит к злокачественным преобразованиям, усиливает инвазивный и метастатический потенциал и оказывает сопротивление терапевтическому вмешательству, что в конечном счете приводит к прогрессированию опухоли и более низким клиническим результатам. В этом исследовании всесторонне изучается ИП3К/АКТ, сигнализирующий о его причастности к различным человече

In this review, we provided an in-depth analysis of the relationships and distinctions between uncontrolled inflammation, fibrosis and cancers, while emphasizing the challenges and opportunities of developing novel therapies for the treatment and/or management of these diseases. We described how drug delivery systems, combination therapy and the integration of tissue-targeted and/or pathways selective strategies could overcome the challenges of current agents for managing and/or treating chroni

Exosomes: A new option for osteoporosis treatment.

Osteoporosis is a systemic bone disease characterized by reduced bone mass and destruction of bone microarchitecture, leading to increased bone fragility and susceptibility to fracture. However, the pathogenesis and molecular mechanisms of this disease remain unclear. Extracellular vesicles, structures originating from the plasma membrane and ranging from 30 nm to 5 µm in diameter, play an important role in intercellular communication in the bone microenvironment. Exosomes are extracellular vesicles that deliver cargo molecules, including endogenous proteins, lipids and nucleic acids. These ca

Myeloma bone disease: Pathophysiology and management.

Multiple myeloma bone disease is marked by severe dysfunction of both bone formation and resorption and serves as a model for understanding the regulation of osteoblasts (OBL) and osteoclasts (OCL) in cancer. Myeloma bone lesions are purely osteolytic and are associated with severe and debilitating bone pain, pathologic fractures, hypercalcemia, and spinal cord compression, as well as increased mortality. Interactions within the bone marrow microenvironment in myeloma are responsible for the abnormal bone remodeling in myeloma bone disease. Myeloma cells drive bone destruction that increases t

Glycoprotein Non-Metastatic Protein B: An Emerging Biomarker for Lysosomal Dysfunction in Macrophages.

Several diseases are caused by inherited defects in lysosomes, the so-called lysosomal storage disorders (LSDs). In some of these LSDs, tissue macrophages transform into prominent storage cells, as is the case in Gaucher disease. Here, macrophages become the characteristic Gaucher cells filled with lysosomes laden with glucosylceramide, because of their impaired enzymatic degradation. Biomarkers of Gaucher cells were actively searched, particularly after the development of costly therapies based on enzyme supplementation and substrate reduction. Proteins selectively expressed by storage macrop

UnlabelledMultiple myeloma is the second most common haematological malignancy. Novel therapies have led to improvement in survival. Current myeloma management is matching the progress made in improved survival through disease control while optimising quality of life with effective supportive care. Supportive treatment is an essential part of the therapeutic management of myeloma patients because it is directed towards improving the patient's quality of life and also can improve survival. The aim of this review is to highlight the relationship among life of quality, supportive care, and improv

Pathogenic Mechanisms of Myeloma Bone Disease and Possible Roles for NRF2.

Osteolytic bone lesions are one of the central features of multiple myeloma (MM) and lead to bone pain, fractures, decreased quality of life, and decreased survival. Dysfunction of the osteoclast (OC)/osteoblast (OB) axis plays a key role in the development of myeloma-associated osteolytic lesions. Many signaling pathways and factors are associated with myeloma bone diseases (MBDs), including the RANKL/OPG and NF-κB pathways. NRF2, a master regulator of inflammatory signaling, might play a role in the regulation of bone metabolism via anti-inflammatory signaling and decreased reactive oxygen s
