Macromolecular crowding: chemistry and physics meet biology (Ascona, Switzerland, 10-14 June 2012).

More than 60 years of biochemical and biophysical studies have accustomed us to think of proteins as highly purified entities that act in isolation, more or less freely diffusing until they find their cognate partner to bind to. While in vitro experiments that reproduce these conditions largely remain the only way to investigate the intrinsic properties of molecules, this approach ignores an important factor: in their natural milieu , proteins are surrounded by several other molecules of different chemical nature, and this crowded environment can considerably modify their behaviour. About 40%

The role of proteasomes in tumorigenesis.

Protein homeostasis is the basis of normal life activities, and the proteasome family plays an extremely important function in this process. The proteasome 20S is a concentric circle structure with two α rings and two β rings overlapped. The proteasome 20S can perform both ATP-dependent and non-ATP-dependent ubiquitination proteasome degradation by binding to various subunits (such as 19S, 11S, and 200 PA), which is performed by its active subunit β1, β2, and β5. The proteasome can degrade misfolded, excess proteins to maintain homeostasis. At the same time, it can be utilized by tumors to deg

Оптимизация доставки каннабидиол: повышение растворимости и проницаемости воды посредством фосфолипидной комплексации.

Каннабидиол (КБР) продемонстрировал терапевтический потенциал в лечении эпилепсии, множественного склероза, болезни Альцгеймера, Паркинсона и Крона. Несмотря на ее многообещающие последствия и анальгетические, антивоспалительные и аксиолитические свойства, полный потенциал КБР сдерживается низкой растворимостью воды (0,7-10 мкг/мл), низкой проницаемостью и химической нестабильностью. Цель этого исследования состояла в том, чтобы повысить проницаемость кишечника (GI) в результате распада, стабильности и проницаемости кишечника КБР путем создания комплекса КБР-фосфолипид (CBD-PLC).

Conditioned Media-Derived Tumor Extracellular Vesicles: Bridging Molecular Insights and Therapeutic Applications in Oncology.

Tumor-derived extracellular vesicles (EVs) are major mediators of oncogenic intercellular communication. However, many studies using conditioned media (CM) recover operationally defined EV- or small EV-enriched fractions rather than biogenesis-proven exosomes. This review synthesizes evidence from CM-derived tumor EV studies and aligns their biological interpretation with current EV nomenclature, characterization, and reporting principles. We first discuss exosome biogenesis as a defined endosomal pathway and then examine how CM collection, serum handling, culture format, oxygen tension, condi

Therefore, this review is devoted to various organic (lipid, polymeric) as well as inorganic nanoparticles based on different building units and providing a wide range of

Controlled Drug Delivery Systems for Oral Cancer Treatment-Current Status and Future Perspectives.

Oral squamous cell carcinoma (OSCC), which encompasses the oral cavity-derived malignancies, is a devastating disease causing substantial morbidity and mortality in both men and women. It is the most common subtype of the head and neck squamous cell carcinoma (HNSCC), which is ranked the sixth most common malignancy worldwide. Despite promising advancements in the conventional therapeutic approaches currently available for patients with oral cancer, many drawbacks are still to be addressed; surgical resection leads to permanent disfigurement, altered sense of self and debilitating physiologica

The Role of Platelet Dysfunctions in the Pathogenesis of the Hemostatic-Coagulant System Imbalances.

Platelet dysfunction plays a critical role in the pathogenesis of various disorders affecting the hemostatic-coagulant system. This review aims to explore the mechanisms by which platelet dysfunctions contribute to the disruption of hemostasis, leading to an increased risk of both thrombosis and bleeding. Platelets, traditionally known for their role in clot formation, can exhibit altered functionality under pathological conditions such as cardiovascular diseases, metabolic disorders, and autoimmune diseases, impacting their interaction with coagulation factors and vascular endothelium. The re

Bone Metastasis of Breast Cancer: Molecular Mechanisms and Therapeutic Strategies.

Bone metastasis is a common complication of many types of advanced cancer, including breast cancer. Bone metastasis may cause severe pain, fractures, and hypercalcemia, rendering clinical management challenging and substantially reducing the quality of life and overall survival (OS) time of breast cancer patients. Studies have revealed that bone metastasis is related to interactions between tumor cells and the bone microenvironment, and involves complex molecular biological mechanisms, including colonization, osteolytic destruction, and an immunosuppressive bone microenvironment. Agents inhibi

Recent advances in biomimetic nanodelivery systems for cancer Immunotherapy.

Tumor immunotherapy is a developing and promising therapeutic method. However, the mechanism of tumor immune microenvironment and individual differences of patients make the clinical application of immunotherapy still very limited. The resulting targeting of the tumor environment and immune system is a suitable strategy for tumor therapy. Biomimetic nanodelivery systems (BNDS) coated with nanoparticles has brought new hope for tumor immunotherapy. Due to its high targeting, maximum drug delivery efficiency and immune escape, BNDS has become one of the options for tumor immunotherapy in the fut

Therapeutic Perspectives on the Modulation of G-Protein Coupled Estrogen Receptor, GPER, Function.

Estrogens exert their physiological and pathophysiological effects via cellular receptors, named ERα, ERβ, and G-protein coupled estrogen receptor (GPER). Estrogen-regulated physiology is tightly controlled by factors that regulate estrogen bioavailability and receptor sensitivity, while disruption of these control mechanisms can result in loss of reproductive function, cancer, cardiovascular and neurodegenerative disease, obesity, insulin resistance, endometriosis, and systemic lupus erythematosus. Restoration of estrogen physiology by modulating estrogen bioavailability or receptor activity

Polybasic nanogels for intracellular co-delivery of paclitaxel and carboplatin: a novel approach to ovarian cancer therapy.

Ovarian cancer is one of the leading causes of cancer-related deaths in women, with limited progress in treatments despite decades of research. Common treatment protocols rely on surgical removal of tumors and chemotherapy drugs, such as paclitaxel and carboplatin, which are capable of reaching cancer cells throughout the body. However, the effectiveness of these drugs is often limited due to toxic reactions in patients, nonspecific drug distribution affecting healthy cells, and the development of treatment resistance. In this study, we introduce a polybasic nanogel system composed of poly(die
