Epigenetic mechanisms, which are involved in the regulation of gene expression, are tightly controlled. Loss of a proper epigenetic control can lead to global epigenetic alterations frequently observed in various diseases including cancer. Aberrant epigenetic changes induced in malignant cells lead to emergence of neoplastic properties, which inhibit cell differentiation and strict cell cycle control but greatly enhance stemness-related features. However, abnormal epigenetic patterns can be reversed by action of epigenetically active agents...

Reducing sugars can react non-enzymatically with amino groups of proteins and lipids to form irreversibly cross-linked macroprotein derivatives called as advanced glycation end products (AGEs). Cross-linking modification of extracellular matrix proteins by AGEs deteriorate their tertiary structural integrity and function, contributing to aging-related organ damage and diabetes-associated complications, such as cardiovascular disease (CVD). Moreover, engagement of receptor for AGEs, RAGE with the ligands evoke oxidative stress generation and inflammatory, thrombotic and fibrotic reactions in various kinds of tissues, further exacerbating the deleterious effects of AGEs on multiple organ systems...

Autophagy, a highly conserved starvation response mechanism with both defensive and protective effects in eukaryotic cells, is a lysosome-mediated degradation process for non-essential or damaged cellular constituents. It plays an important role in the cell survival, differentiation and development to maintain homeostasis. Autophagy is involved in cardiovascular diseases, cerebrovascular diseases, and neurodegenerative disease, as well as tumours. Thus, modulating autophagy may provide potential therapeutic strategies...

BACKGROUND: Biomedical sciences use a variety of data sources on drug molecules, genes, proteins, diseases and scientific publications etc. This system can be best pictured as a giant data-network linked together by physical, functional, logical and similarity relationships. A new hypothesis or discovery can be considered as a new link that can be deduced from the existing connections. For instance, interactions of two pharmacons - if not already known - represent a testable novel hypothesis...

This review mainly focuses on the medical and biological role of relatively poor studied enzymes known as sialidases. Structure and function of sialic acid, particularly as a component of gangliosides and plasma lipoproteins is described. Among the whole variety of sialidases, trans-sialidase is of special interest, since it is capable of removing sialic acid from the low density lipoprotein (LDL) particles and transferring it to different acceptors in plasma. Desialylation of LDL in turn endow them the capacity to accumulate in the smooth muscle cells of human aortic intima, highlighting the important role of desialylation in atherogenesis...

Heart failure, hypertension, cirrhosis and nephritic syndrome are among conditions that alter volume and composition of body fluids and are modulated by diuretics. Natural products are important source of diuretics and have been considered remarkable alternative with greater effectiveness and fewer side effects. However, many of these plants used in traditional medicine must be scientifically assessed about their efficacy and toxicity. Despite the large number of published articles claiming that plants or plant-derived components may act as diuretic agents, few studies have addressed the mechanism of action of medicinal plants...

Systemic hypersensitivity (HS) to corticosteroids (CS) is paradoxical but does exist. Some patients with a previous contact allergy to topical CS may develop a systemic contact dermatitis (SCD) while receiving CS orally or intravenously. However, a previous contact sensitization is not mandatory for developing a systemic HS to CS. Acute or delayed urticaria can occur in immediate HS. Immediate HS can be due to excipients, mainly carboxymethylcellulose or to CS themselves. Delayed reactions, mainly maculopapular rash and acute generalized exanthematous pustulosis can occur...
