Circulating levels of IGF-1 may decrease under several circumstances like ageing, metabolic syndrome, and advanced cirrhosis. This reduction is associated with insulin resistance, dyslipidemia, progression to type 2 diabetes, and increased risk for cardiovascular diseases. However, underlying mechanisms between IGF-1 deficiency and cardiovascular disease remain elusive. The specific aim of the present work was to study whether the partial IGF-1 deficiency influences heart and/or coronary circulation, comparing vasoactive factors before and after of ischemia-reperfusion (I/R)...

Despite the fact that ischemic stroke has been considered a leading cause of mortality in the world, recent advances in our understanding of the pathophysiological mechanisms underlying the ischemic injury and the treatment of acute ischemic stroke patients have led to a sharp decrease in the number of stroke deaths. However, this decrease in stroke mortality has also led to an increase in the number of patients that survive the acute ischemic injury with different degrees of disability. Unfortunately, to this date we do not have an effective therapeutic strategy to promote neurological recovery in these growing population of stroke survivors...

Acute spinal cord injury (SCI) is one of the serious central nervous system injuries, which can lead to significant neurological impairments and a reduction in quality of life with loss in sensory and motor functions. Although recent advancements contribute to the understanding of the underlying pathophysiological processes developed after SCI, currently, there is limited innovative and effective treatment options besides conventional rehabilitation and management of SCI to alleviate the condition. Improvements in neurological functions of the individuals with SCI depend mainly on the mechanical damage occurring in the primary injury and on pathophysiological alterations associated with secondary damage...

There is convincing evidence from both human and animal studies suggesting that the gut microbiota plays an important role in regulating immune responses associated with the development of asthma. Certain intestinal microbial strains have been demonstrated to suppress or impair immune responsiveness in asthma experimental models, suggesting that specific species among gut commensal microbiota may play either a morbific or phylactic role in the progression of asthma. Evidence to date suggests that the intestinal microbiota represent fertile targets for prevention or management of asthma...

Multiple sclerosis (MS) is a highly prevalent demyelinating disorder, presumed to be driven by an autoimmune response toward the central nervous system (CNS) components. All currently available treatments modulate the immune system globally and besides the reduction of disease activity, they may also impose considerable disturbances on the immune protective mechanisms. Thus, induction of antigen-specific immune tolerance remains the ultimate goal of MS therapy. Such approach carries promising therapeutic perspectives and, above all, a desirable safety profile...

Marcela Dvorakova, Premysl Landa
Resveratrol and other natural stilbenoids, including piceatannol, pterostilbene, and gnetol, are well-known anti-inflammatory compounds with indisputable activity in vitro as well as in vivo. Their molecular targets include inducible nitric oxide synthase, cyclooxygenases, leukotrienes, nuclear factor kappa B, tumor necrosis factor α, interleukins and many more. This anti-inflammatory activity together with their antioxidant activity is believed to stand behind their other positive health effects against cancer, cardiovascular and neurodegenerative diseases or diabetes...

The order Mucorales, which includes the agents of mucormycosis, comprises a large number of species. These fungi are characterized by high-level resistance to most currently available antifungal drugs. Standardized antifungal susceptibility testing methods are now available, allowing a better understanding of the in vitro activity of antifungal drugs against members of Mucorales. Such tests have made apparent that antifungal susceptibility within this group may be species-specific. Experimental animal models of mucormycosis have also been developed and are of great importance in bridging the gap between in vitro results and clinical trials...

Persistent hyperglycaemia coupled with inflammation plays an important role in the pathogenesis of diabetic nephropathy (DN). Present study examined the therapeutic potential of taraxerol isolated from the methanol extract of Abroma augusta leaf against DN using rodent model of type 2 diabetes (T2D). T2D was experimentally induced by high fat diet and a single low-single dose of streptozotocin (35mg/kg, i.p.). Accumulation of serum creatinine, urea, and uric acid, activation of lactate dehydrogenase and creatinin kinase, and release of urinary albumin represented the glomerular damage and the progression of nephropathy in T2D rats...

5'-Aza-2'-deoxycytidine (5-Aza-dC) is a demethylating drug that causes genome-wide hypomethylation resulting in the expression of several tumor suppressor genes causing growth arrest of cancer cells. Cancer is well established as a multifactorial disease and requires multi-module therapeutics. Search for new drugs and their approval by FDA takes a long time. Keeping this in view, research on new functions of FDA-approved anticancer drugs is desired to expand the list of multi-module functioning drugs for cancer therapy...

Butyrate is a bacterial metabolite of dietary fiber in the colon that has been used to treat inflammatory disease. However, the effect of oral supplementation with butyrate on colitis has not been fully explored. We evaluated the effects of and mechanisms underlying oral supplementation with butyrate on experimental murine colitis. In an in vitro study, we found that LPS induced the secretion of cytokines (i.e., IL-8 in COLO 205; TNF-α, IL-6, IL-12, and IL-10 in RAW 264.7; and TNF-α, IL-6 and IL-12 in peritoneal macrophages obtained from IL-10-deficient [IL-10(-/-)] mice)...

Constitutive gene expression is not always the appropriate expression system because the unphysiological levels of expressed protein could be detrimental in studies examining biological roles of proteins, or continued expression may be unnecessary after therapeutic effects have been achieved in gene therapy . We have utilized pharmacologically regulated gene expression systems to achieve fine control of gene expression levels which facilitate research in basic biology and translates to use in experimental gene therapy studies...

Peptide mapping with liquid chromatography-tandem mass spectrometry (LC-MS/MS) is an important analytical method for characterization of post-translational and chemical modifications in therapeutic proteins. Despite its importance, there is currently no consensus on the statistical analysis of the resulting data. In this manuscript, we distinguish three statistical goals for therapeutic protein characterization: (1) estimation of site occupancy of modifications in one condition, (2) detection of differential site occupancy between conditions, and (3) estimation of combined site occupancy across multiple modification sites...
