Membrane proteins sense extracellular cues and transduce intracellular signaling to coordinate directionality and speed during cellular migration. They are often localized to specific regions, as with lipid rafts or tetraspanin-enriched microdomains; however, the dynamic interactions of tetraspanins with diverse receptors within tetraspanin-enriched microdomains on cellular surfaces remain largely unexplored. Here, we investigated effects of tetraspan(in) TM4SF5 (transmembrane 4 L six family member 5)-enriched microdomains (T5ERMs) on the directionality of cell migration...

NAD(+) availability decreases with age and in certain disease conditions. Nicotinamide mononucleotide (NMN), a key NAD(+) intermediate, has been shown to enhance NAD(+) biosynthesis and ameliorate various pathologies in mouse disease models. In this study, we conducted a 12-month-long NMN administration to regular chow-fed wild-type C57BL/6N mice during their normal aging. Orally administered NMN was quickly utilized to synthesize NAD(+) in tissues. Remarkably, NMN effectively mitigates age-associated physiological decline in mice...

Liposomes are used for encapsulation of the active compounds in different therapies, with the increasing frequency. The important areas of clinical applications of liposomes are cancer targeted treatment, antibiotic delivery or regenerative medicine. The liposomes can transfer both hydrophilic and hydrophobic compounds and have the lipid bilayer which imitates the cell membrane. Liposomes additionally may extend half-live period of drugs and protect them against the elimination in different ways, such as phagocytosis, enzymatic cleavage or exclusion by detoxification...

Strenuous physical exercise leads to platelet activation that is normally counterbalanced by the production of endothelium-derived anti-platelet mediators, including prostacyclin (PGI2) and nitric oxide (NO). However, in the case of endothelial dysfunction, e.g. in atherosclerosis, there exists an increased risk for intravascular thrombosis during exercise that might be due to an impairment in endothelial anti-platelet mechanisms. In the present work, we evaluated platelet activation at rest and following a single bout of strenuous treadmill exercise in female ApoE/LDLR(-)(/-) mice with early (3-month-old) and advanced (7-month-old) atherosclerosis compared to female age-matched WT mice...

Protein kinase C (PKC) belongs to a family of serine/threonine kinases and is evolutionary conserved among eukaryotes. It contains several functional domains, with the C1 domain being identified as a membrane-targeting module. Diacylglycerol (DAG) and phorbol esters bind to the C1 domain to enhance its kinase activity. The C1 domain is conserved in PKC (Pkc1) in the budding yeast Saccharomyces cerevisiae; however, its kinase activity does not respond to DAG. Although the C1 domain of Pkc1 physically interacts with the small GTPase Rho1, the interaction between C1 domain and lipids has not yet been characterized...

Fibroblast growth factor 21 (FGF21) is an endocrine-member of the FGF family. It is synthesized mainly in the liver, but it is also expressed in adipose tissue, skeletal muscle, and many other organs. It has a key role in glucose and lipid metabolism, as well as in energy balance. FGF21 concentration in plasma is increased in patients with obesity, insulin resistance, and metabolic syndrome. Recent findings suggest that such increment protects tissue from an increased oxidative stress environment. Different types of physical stress, such as strenuous exercising, lactation, diabetic nephropathy, cardiovascular disease, and critical illnesses, also increase FGF21 circulating concentration...

Recently, we demonstrated that the hypothalamic S1PR1/STAT3 axis plays a critical role in the control of food consumption and energy expenditure in rodents. Here, we found that reduction of hypothalamic S1PR1 expression occurs in an age-dependent manner, and was associated with defective thermogenic signaling and weight gain. To address the physiological relevance of these findings, we investigated the effects of chronic and acute exercise on the hypothalamic S1PR1/STAT3 axis. Chronic exercise increased S1PR1 expression and STAT3 phosphorylation in the hypothalamus, restoring the anorexigenic and thermogenic signals in middle-aged mice...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

The discovery of brown adipose tissue (BAT) as a key regulator of energy expenditure has sparked interest in identifying novel soluble factors capable of activating inducible BAT (iBAT) to combat obesity. Using a high content cell-based screen, we identified Fibroblast Growth Factor (FGF) 16 as a potent inducer of several physical and transcriptional characteristics analogous to those of both classical BAT and iBAT. Over-expression of Fgf16 in vivo recapitulated several of our in vitro findings, specifically significant induction of Ucp1 gene and UCP1 protein expression in inguinal white adipose tissue (iWAT), a common site for emergent active iBAT...
