Extracellular vesicles (EVs) - including exosomes, microvesicles and apoptotic bodies - have received much scientific attention last decade as mediators of a newly discovered cell-to-cell communication system, acting at short and long distances. EVs carry biologically active molecules, thus providing signals that influence a spectrum of functions in recipient cells during various physiological and pathological processes. Recent findings point to EVs as very attractive immunomodulatory therapeutic agents, vehicles for drug delivery and diagnostic and prognostic biomarkers in liquid biopsies...

Extracellular vesicles (EVs), including exosomes, microvesicles, and apoptotic bodies, play an important role in cellular communication during skeletal growth and homeostasis. Bioactive molecules carried by EVs are transported to neighboring and distant cells to trigger a series of signaling cascades influencing bone homeostasis. The bioactive activities of osteoclast-derived EVs include regulation of osteoclastogenesis and osteoclast-osteoblast communication. As osteoclast-derived EVs have the potential to regulate osteoclasts and osteoblasts, their application in osteoporosis and other bone metabolic disorders is currently under investigation...

Obesity and diabetes are associated with diabetic cardiomyopathy (DCM). However, the pathogenesis of DCM is not fully understood. Cannabinoid receptor gene (CNR1) has been a drug target for the treatment of obesity. Here, we reported that CNR1 expression was increased in high fat diet (HFD)-induced heart of mice. Following, the wild type (CNR1+/+ ) and CNR1-knockout (CNR1-/- ) mice were employed and subjected to HFD treatments for 16 weeks to further investigate the effects of CNR1 on DCM. The results indicated that CNR1 knockout mice after HFD feeding exhibited a significant decrease of body weight and lipid accumulation in serum...

Olfactory receptors (ORs) are not exclusively expressed in the olfactory sensory neurons; they are also observed outside of the olfactory system in all other human tissues tested to date, including the testis, lung, intestine, skin, heart, and blood. Within these tissues, certain ORs have been determined to be exclusively expressed in only one tissue, whereas other ORs are more widely distributed in many different tissues throughout the human body. For most of the ectopically expressed ORs, limited data are available for their functional roles...

Apoptosis is fundamental in several morphogenetic processes and ultimately determines the mass, shape, and function of the various tissues and organs that form the animal body. This process is a gene-regulated process that plays fundamental roles in several normal and pathological conditions. Apoptosis is most often detected during embryonic development. Although the nervous tissue is traditionally regarded as being fundamentally constituted by postmitotic nonproliferating cells, analysis of cell proliferation and apoptosis in vivo has recently gained an increasing importance mainly during embryonic development because there is large evidence that drug-induced apoptosis is the most likely candidate for the behavioral deficits...

Neuronal loss alongside altered energy metabolism, are key features of Huntington's disease (HD) pathology. The orexigenic gut-peptide hormone ghrelin is known to stimulate appetite and affect whole body energy metabolism. Liraglutide is an efficient anti-type 2 diabetes incretin drug, with neuroprotective effects alongside anorectic properties. Combining liraglutide with the orexigenic peptide ghrelin may potentially promote brain/cognitive function in HD. The R6/2 mouse model of HD exhibits progressive central pathology, weight loss, deranged glucose metabolism, skeletal muscle atrophy and altered body composition...

Triple-negative breast cancer (TNBC) represents a relatively small proportion of all BCs but a relatively large proportion of BC-related death. Thus, more effective therapeutic strategies are needed for the management of TNBC. We demonstrated that the stimulation of apoptosis by the binding of secreted acetylated-apurinic apyrimidinic endonuclease 1/redox factor-1 (Ac-APE1/Ref-1) to the receptor for advanced glycation end products (RAGE) was essential for TNBC cell death in response to hyperacetylation. The aim of the present study was to assess the potential therapeutic efficacy of secretory Ac-APE1/Ref-1 in orthotopic TNBC xenografts in vivo...

Kidney transplantation entails a high likelihood of endothelial injury. The endothelium is a target of choice for injury by ischemia-reperfusion, alloantibodies, and autoantibodies. A certain degree of ischemia-reperfusion injury inevitably occurs in the immediate posttransplant setting and can manifest as delayed graft function. Acute rejection episodes, whether T-cell or antibody-mediated, can involve the graft micro- and macrovasculature, leading to endothelial injury and adverse long-term consequences on graft function and survival...
