This study clearly shows for the first time the expression of CVB4 VP1 structure protein alone can form VLPs in the baculovirus-infected insect cell keeping conserved both characteristics and morphology.Many metabolic and neurodegenerative diseases are associated with protein misfolding and aggregation. Insulin a key hormone, under certain conditions aggregates and forms pathological amyloid fibrils. Several polyphenols have been studied extensively to elucidate their inhibitory effect on amyloid formation. In the present study, we used insulin as an amyloid model to test the mechanism and efficacy of rutin as an anti-amyloidogenic molecule. By using electron microscopy, dynamic light scattering and circular dichroism spectroscopy, we show that rutin inhibits the insulin aggregate and fibril formation. Further, rutin interacts with insulin directly and inhibits fibril formation in a dose-dependent manner as demonstrated by micro scale thermophoresis experiments. The molecular docking study predicted the potential binding pocket of rutin at the interface of chain A and chain B of insulin thereby preventing it from forming the aggregates. Since, rutin is a natural anti-oxidant, we studied its role in diminishing amyloid fibril induced cytotoxicity and apoptosis. Rutin, decreases the insulin amyloid fibrils-induced Neuro-2a cytotoxicity by reducing reactive oxygen species (ROS) levels which in turn downregulates Bax and upregulates Bcl-2 and pBad proteins. These findings suggest the potential action of rutin in preventing protein misfolding, cell death, and serves as a lead structure to design novel anti-amyloidosis compounds.Microsatellite markers are a useful genetic tool to answer ecological and conservation genetics questions. Microsatellite primers were developed and characterized to evaluate forest fragmentation effects on genetic structure, diversity and gene flow patterns in the dioecious tropical tree Astroniumgraveolens (Anacardiaceae). Using genomic library enrichment, sixteen microsatellite loci were developed for A.graveolens. Polymorphism was evaluated in 80 individuals from four localities in Mexico. The overall number of alleles detected was 63, average alleles per locus 3.9 with a range from one to 11 per locus. Cross amplification trails on related species in the Anacardiaceae family Spondiaspurpurea and Amphipterygiumadstringens, achieved successful amplification for all primers. Microsatellite markers described here are the first to be characterized for A.graveolens. These genetic markers will be a useful tool to assess the genetic consequences of habitat fragmentation and selective logging on A.graveolens populations. Cross amplification success on S.purpureaandA.adstringens suggest that they may be used for population genetic studies in other species within the family.Blood glucose homeostasis and insulin signaling pathway regulation take a vital role in the management of diabetes mellitus. Our present was designed to explore the mechanism of the blood homeostasis, regulation of oxidative stress and insulin signaling pathway by guava leaf extract (GLE). Diabetes mellitus was induced in male albino Wistar by streptozotocin (STZ) (Single dose-40 mg/kg b.w.). As an extension STZ rats received GLE (GLE; 200 mg/kg b.w). At the end of the study the lipid peroxidation products, antioxidants, insulin signaling genes were analyzed. Treatment with GLE resulted in decreased plasma and skeletal muscle lipid peroxidation markers, increased antioxidants, and improved insulin signaling genes. GLE treatment helps to maintain blood homeostasis alleviates oxidative stress and regulates the insulin signaling genes in skeletal muscle. Overall the results suggest GLE treatment regulates blood glucose, inhibits oxidative stress, and importantly it regulates insulin signaling pathway genes in skeletal muscle. Further studies on the GLE role in other important pathways can add additional strength to the claim that GLE is a strong anti-diabetic candidate.INTRODUCTION Glioblastoma multiforme (GBM) is a highly malignant glial tumor, affecting men more often than women. Lys05 clinical trial The reason for this gender-specific predominance remains unclear, raising the question whether these effects are subject to hormonal control. The purpose of this study was to examine the expression of estrogen receptor alpha (ERα) and aromatase in human GBM tissue samples in relation to patient survival and furthermore to investigate the effect of standard chemotherapy in combination with estradiol treatment on glioblastoma tumor cell lines in vitro. METHODS 60 tissue samples (31 male, 29 female) of GBM patients were analysed with immunohistochemistry for ERα and aromatase for survival analyses. The cell lines LN18 and LN229 were treated with 17β-estradiol (E2) in different dosing regimens and the cell viability was measured with MTT assay. After estradiol pre-treatment Temozolomide was added and tested again. RESULTS High expression of ERα and aromatase in the GBM tissue samples was associated with significantly longer survival times of GBM patients, regardless of gender and body-mass-index. The treatment with high concentrations of estradiol resulted in lower tumor cell viability, compared to control. The cells significantly showed a stronger sensitivity against Temozolomid (TMZ) after estradiol pre-treatment. CONCLUSION ERα-expression of glial tumour cells seems to play an important prognostic role as a biomarker in GBM, as well as the expression of the enzyme Aromatase. The combined treatment of GBM with standard chemotherapy and estradiol may be beneficial to patient's survival.In people with normal sight, mental simulation (motor imagery) of an experienced action involves a multisensory (especially kinesthetic and visual) emulation process associated with the action. Here, we examined how long-term blindness influences sensory experience during motor imagery and its neuronal correlates by comparing data obtained from blind and sighted people. We scanned brain activity with functional magnetic resonance imaging (fMRI) while 16 sighted and 14 blind male volunteers imagined either walking or jogging around a circle of 2 m radius. In the training before fMRI, they performed these actions with their eyes closed. During scanning, we explicitly instructed the blindfolded participants to generate kinesthetic motor imagery. After the experimental run, they rated the degree to which their motor imagery became kinesthetic or spatio-visual. The imagery of blind people was more kinesthetic as per instructions, while that of the sighted group became more spatio-visual. The imagery of both groups commonly activated bilateral frontoparietal cortices including supplementary motor areas (SMA).
