This review discusses research progress on the effect of bacterial dysbiosis from a metabolic point of view, particularly on the biochemical mechanisms of butyrate, one of the main short chain fatty acids (SCFAs) with anti-inflammatory and anti-tumor properties

Vascular endothelial growth factor signaling in health and disease: from molecular mechanisms to therapeutic perspectives.

Vascular endothelial growth factor (VEGF) signaling is a critical regulator of vasculogenesis, angiogenesis, and lymphangiogenesis, processes that are vital for the development of vascular and lymphatic systems, tissue repair, and the maintenance of homeostasis. VEGF ligands and their receptors orchestrate endothelial cell proliferation, migration, and survival, playing a pivotal role in dynamic vascular remodeling. Dysregulated VEGF signaling drives diverse pathological conditions, including tumor angiogenesis, cardiovascular diseases, and ocular disorders. Excessive VEGF activity promotes tu

Окисляющий стресс в функции мозга.

Окисляющий стресс (OS) является важным фактором в патофизиологии многочисленных нейродегенеративных расстройств, таких, как болезнь Паркинсона, множественный склероз, цереброваскулярная патология или болезнь Альцгеймера. OS также оказывает значительное влияние на прогресс между различными нейродегенеративными расстройствами. Несбалансированность между образованием реактивных видов кислорода (РОС) и способностью организма нейтрализовать эти токсичные побочные продукты делает мозг подверженным окислительным повреждениям. Увеличение количества ROS может привести к сбоям в клетке, апоптозу и нейро

Beyond regulations at DNA levels: A review of epigenetic therapeutics targeting cancer stem cells.

In the past few years, the paramount role of cancer stem cells (CSCs), in terms of cancer initiation, proliferation, metastasis, invasion and chemoresistance, has been revealed by accumulating studies. However, this level of cellular plasticity cannot be entirely explained by genetic mutations. Research on epigenetic modifications as a complementary explanation for the properties of CSCs has been increasing over the past several years. Notably, therapeutic strategies are currently being developed in an effort to reverse aberrant epigenetic alterations using specific chemical inhibitors. In thi

BackgroundNew pharmacological therapies are challenging the healthcare systems, and there is an increasing need to assess their therapeutic value in relation to existing alternatives as well as their potential budget impact. Consequently, new models to introduce drugs in healthcare are urgently needed. In the metropolitan health region of Stockholm, Sweden, a model has been developed including early warning (horizon scanning), forecasting of drug utilization and expenditure, critical drug evaluation as well as structured programs for the introduction and follow-up of new drugs. The aim of this

Tumour Cell Size Control and Its Impact on Tumour Cell Function.

Cell size is an important component of cell morphological characteristics. It reflects the characteristics of the cell type, nutritional status, growth stage and physiological function. The cell size of cells of the same type tends to be homogeneous and stable. However, in tumour cells, mutations in cell cycle genes and cytoskeletal genes and overexpression of the corresponding signalling pathways often lead to large variations in tumour cell size. Tumour cells regulate cell size and growth and proliferation through multiple signalling pathways, such as PI3K/Akt/mTOR, Myc and Hippo pathways, w

Arrhythmias, conduction disorders and sudden cardiac death in cancer patients and survivors: expert opinion of the working groups on cardio-oncology and on electrophysiology of the hellenic cardiac society.

Advances in cancer therapeutics have significantly improved patient survival; however, cardiotoxic effects-including arrhythmias-have emerged as a growing clinical concern. This expert opinion, developed by the Working Groups on Cardio-Oncology and Electrophysiology of the Hellenic Cardiological Society, aims to raise awareness of the increasing burden of arrhythmias in cancer patients and survivors.

Immunosenescence: signaling pathways, diseases and therapeutic targets.

Immunosenescence refers to the abnormal activation or dysfunction of the immune system as people age. Inflammaging is a typical pathological inflammatory state associated with immunosenescence and is characterized by excessive expression of proinflammatory cytokines in aged immune cells. Chronic inflammation contributes to a variety of age-related diseases, such as neurodegenerative disease, cancer, infectious disease, and autoimmune diseases. Although not fully understood, recent studies contribute greatly to uncovering the underlying mechanisms of immunosenescence at the molecular and cellul

Targeted synthesis of a trimethoxyphenyltetrahydropyrimidine analogue designed as a DNA intercalator: in silico, multi-spectroscopic, thermodynamic, and in vitro approaches.

Based on the rational design of DNA intercalators and Topo-II inhibitors and taking into consideration the main pharmacophoric features of doxorubicin (Dox) as a reference standard, we theoretically designed novel substituted tetrahydropyrimidine analogues (T1-35). The designed analogues (T1-35) were investigated for their inhibitory potential towards the hybrid DNA and Topo-II target receptor using molecular docking. Interestingly, the theoretically designed analogue T30 with a 3,4,5-trimethoxy phenyl side chain was found to be the superior candidate, achieving a binding score of -7.06 kcal m

Unveiling the comorbidity burden of male breast cancer.

Male breast cancer (MBC) is a rare condition with unique characteristics compared to female breast cancer (FBC). Despite its scarceness, there is growing evidence that MBC should not be studied and treated as FBC due to factors like later diagnosis stage and distinct genetic makeup. Retrospective observational study in the EpiChron Cohort, selecting all the prevalent patients with breast cancer between 2010 and 2019. Logistic models were used to determine associated comorbidities. Between 2010 and 2019, 105 MBC and 11,657 FBC patients were found in the EpiChron Cohort. MBC patients had a high

Role of mitochondria in physiological activities, diseases, and therapy.

Mitochondria are generally considered essential for life in eukaryotic organisms because they produce most of the energy or adenosine triphosphate (ATP) needed by the cell. Beyond energy production, it is now widely accepted that mitochondria also play a pivotal role in maintaining cellular homeostasis and signaling. The two core processes of mitochondrial dynamics, fission and fusion, serve as crucial foundations for maintaining mitochondrial morphology, distribution, and quantity, thereby ensuring cellular homeostasis. Mitochondrial autophagy (mitophagy) ensures the selective degradation of

Насколько общим является гиперкортизолизм у пациентов с гипертензией? Факторы риска, эпидемиология и диагностика.

Эндогенный гиперкортизолизм (ЭГК) является недооцененным и клинически значительным фактором гипертонии, особенно резистентной гипертонии. После того, как EHC считается редким субъектом, он теперь воспринимается как спектр избытка кортизола, связанного с неблагоприятными кардиометаболическими результатами и ущербом, причиненным мишени. Недавно проведенные широкомасштабные исследования свидетельствуют о значительном увеличении распространенности ЭГК среди пациентов с устойчивой гипертонией и трудноконтролируемым диабетом, зачастую в отсутствие классических особенностей кушингоида. В настоящем об
