Advanced Technologies for Large Scale Supply of Marine Drugs.

Marine organisms represent a source of unique chemical entities with valuable biomedical potentialities, broad diversity, and complexity. It is essential to ensure a reliable and sustainable supply of marine natural products (MNPs) for their translation into commercial drugs and other valuable products. From a structural point of view and with few exceptions, MNPs of pharmaceutical importance derive from the so-called secondary metabolism of marine organisms. When production strategies rely on marine macroorganisms, harvesting or culturing coupled with extraction procedures frequently remain t

The Future of Oncology in Psychiatric Medications.

Recent years have provided numerous reports on the mechanisms of action of psychiatric medications (antidepressants, antipsychotics, mood stabilizers, and antidementia drugs) that directly inhibit the growth of cancer cells, as well as on their indirect effects on the psyche and immune system, and their supportive effects on chemotherapeutic agents. The mechanisms of the anticancer activity of psychiatric drugs include inhibition of dopamine and N-methyl-D-aspartate receptors that work via signaling pathways (PI3K/AKT/mTOR/NF-κB, ERK, Wnt/ß-catenin, and bcl2), metabolic pathways (ornithine dec

Двойная роль микроглии в множественном склерозе и его последствия для диагностики и ремонта.

Микроглия играет ключевую роль в развитии, иммунной слежке и восстановлении центральной нервной системы. Эти клетки играют многогранную роль в множестве склероза (MS), при этом есть основания полагать, что микроглия может способствовать как активному воспалению, так и воспалению. Например, было продемонстрировано, что микроглия может поддерживать разработку олигодендроцитов и фигоцитоза миелиновых обломков, способствуя тем самым надлежащему восстановлению. Однако чрезмерная активация микроглии в повреждениях MS усугубляет нейроинфламму, высвобождая подстрекательские цитокины и облегчая активац

Topical Simvastatin Improves Lesions of Diffuse Normolipemic Plane Xanthoma by Inhibiting Foam Cell Pyroptosis.

Xanthoma pathogenesis is speculated to be associated with oxidized low-density lipoprotein (ox-LDL) deposition, although this remains unclear. Most patients with diffuse plane xanthomas present elevated blood lipid levels, and they benefit from treatment with oral lipid-lowering agents. However, there is no available treatment for diffuse normolipemic plane xanthoma (DNPX). In this study, for the first time, we used a topical simvastatin ointment to treat DNPX in three pediatric patients and observed favorable results. Immunofluorescence staining showed that the pyroptotic pathway was signific

Circadian clock and cancer.

Circadian rhythms play a critical role in regulating physiological and behavioral processes, such as the sleep-wake cycle, hormone secretion, and metabolism. These rhythms are controlled by endogenous biological clocks, which are synchronized with environmental cues, primarily the light-dark cycle. Notably, disruption or reprogramming of circadian rhythms is closely associated with cancer initiation, progression, and treatment response. At the molecular level, the dysregulation of core clock genes can disturb normal cellular rhythms, leading to aberrant cell proliferation, impaired DNA repair,

In-Depth Analysis of the Extracorporeal Proteome Adsorbed to Dialysis Membranes during Hemodialysis.

Used hemodialysis membranes (HD-M) are a valuable reservoir of biological information. Proteins bind to HD-M, but whether this process depends on the type of membrane or patient factors or selectively affects specific protein classes has not been adequately elucidated. State-of-the-art proteomics techniques are capable of identifying and quantifying this therapy-specific subproteome to enable the analysis of disease- or membrane-induced pathophysiologies. We demonstrate the feasibility of the deep proteomic characterization of the extracorporeal proteome adsorbed to HD-M. A shotgun proteomics

Autoinflammatory Keratinization Diseases-The Concept, Pathophysiology, and Clinical Implications.

Recent advances in medical genetics elucidated the background of diseases characterized by superficial dermal and epidermal inflammation with resultant aberrant keratosis. This led to introducing the term autoinflammatory keratinization diseases encompassing entities in which monogenic mutations cause spontaneous activation of the innate immunity and subsequent disruption of the keratinization process. Originally, autoinflammatory keratinization diseases were attributed to pathogenic variants of CARD14 (generalized pustular psoriasis with concomitant psoriasis vulgaris, palmoplantar pustulosis

Short-chain acyl post-translational modifications in cancers: Mechanisms, roles, and therapeutic implications.

Post-translational modifications (PTMs) play a pivotal role in epigenetic regulation and are key pathways for modulating protein functionality. PTMs involve the covalent attachment of distinct chemical groups, such as succinyl, crotonyl, and lactyl, at specific protein sites, which alter protein structure, function, stability, and activity, ultimately influencing biological processes. Recently, metabolically derived short-chain acylation modifications (with acyl groups containing fewer than six carbon atoms) have been progressively identified, such as butyrylation, succinylation, crotonylation

Docosahexaenoic Acid Modulates a HER2-Associated Lipogenic Phenotype, Induces Apoptosis, and Increases Trastuzumab Action in HER2-Overexpressing Breast Carcinoma Cells.

In breast cancer, lipid metabolic alterations have been recognized as potential oncogenic stimuli that may promote malignancy. To investigate whether the oncogenic nature of lipogenesis closely depends on the overexpression of HER2 protooncogene, the normal breast cell line, HB4a, was transfected with HER2 cDNA to obtain HER2-overexpressing HB4aC5.2 cells. Both cell lines were treated with trastuzumab and docosahexaenoic acid. HER2 overexpression was accompanied by an increase in the expression of lipogenic genes involved in uptake (CD36), transport (FABP4), and storage (DGAT) of exogenous fat

Short and Long Non-Coding RNAs in Renal Cell Carcinoma.

Renal cell carcinoma (RCC) represents the most frequent kidney malignancy and remains a major clinical challenge due to its often silent onset, high metastatic potential, and limited responsiveness to conventional chemotherapy. Increasing evidence indicates that non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are key regulators of RCC tumorigenesis, progression, and therapy resistance. Rather than providing a purely descriptive overview, this review focuses on emerging mechanistic paradigms through which ncRNAs actively shap

Reprogramming of nitrogen metabolism in tumors: mechanisms and therapeutic implications.

Nitrogen metabolism plays a key role in maintaining normal physiological functions of the organism and cell proliferation and differentiation. Nitrogen metabolism in normal human body maintains a dynamic balance to meet the body's demand for synthesis of biological macromolecules such as proteins and nucleic acids. However, in the process of tumor development, the nitrogen metabolism of tumor cells is reprogrammed to meet the demand of rapid proliferation, showing significantly different metabolic characteristics from normal cells. Key enzymes in the tumor microenvironment affect nitrogen meta

Sympathetic nervous system in tumor progression and metabolic regulation: mechanisms and clinical potential.

Tumor progression is characterized by profound metabolic alterations and dynamic interactions within the tumor microenvironment (TME), which enable rapid proliferation, immunoinvasion, and metastasis. The sympathetic nervous system (SNS), which has been best known for its role in stress regulation, has emerged as a critical regulator of tumor metabolism. The SNS influences glucose, lipid and glutamine metabolism in tumor cells and stromal components by releasing neurotransmitters such as norepinephrine (NE), creating a pro-tumor metabolic and immunosuppressive microenvironment. SNS signaling e
