Toll like receptors (TLRs) are involved in the modulation of diverse host genes expression through a complex network of signalling events that allow for an appropriate response to a microbial pathogen. In the present work we used TLR6KO mice in order to study the role of TLR6 in the immune discrimination of lipids from two Babesia bovis strains, attenuated R1A (LA) and virulent S2P (LV), and th...

K. Ho (ed.), Growth Hormone Related Diseases and Therapy: A Molecular and Physiological Perspective for the Clinician, Contemporary Endocrinology, DOI 10.1007/978-1-60761-317-6_2, © Springer Science+Business Media, LLC 2011 Abstract Ghrelin, a 28 amino acid octanoylated peptide predominantly produced by the stomach, was discovered to be the natural ligand of the type 1a growth hormone (GH) secr...

It has previously been reported that growth hormone secretagogues (GHS) may have a role in the regulation of bone metabolism in animals and humans. In this study we evaluated the effect of ghrelin, the endogenous ligand of GHS receptors, on the proliferation rate and on osteoblast activity in primary cultures of rat calvaria osteoblasts. In the same experiments, we compared the effects of ghrel...

Melatonin serves pleiotropic functions in prompting plant growth and resistance to various stresses. The accurate biosynthetic pathway of melatonin remains elusive in plant species, while the N-acetyltransferase and O-methyltransferase were considered to be the last two key enzymes during its biosynthesis. To investigate the biosynthesis and metabolic pathway of melatonin in plants, the RNA-seq...

Corticosterone and total ghrelin levels are increased in somatostatin (SST) knockout mice (Sst-/-) compared with SST-intact controls (Sst+/+). Because exogenous ghrelin can increase glucocorticoids, the question arises whether elevated levels of ghrelin contribute to elevated corticosterone levels in Sst-/- mice. We report that Sst-/- mice had elevated mRNA levels for pituitary proopiomelanocor...

In a study of the Bosnian-Herzegovinian (B&H) population, Y-chromosome marker frequencies for 100 individuals, generated using the PowerPlex Y23 kit, were used to perform Y-chromosome haplogroup assignment via Whit Athey's Haplogroup Predictor. This algorithm determines Y-chromosome haplogroups from Y-chromosome short tandem repeat (Y-STR) data using a Bayesian probability-based approach. The m...

The four regulatory subunits (R1A, R1B, R2A, R2B) of protein kinase A (PKA) are differentially expressed in several cancer cell lines and exert distinct roles in both cell growth and cell differentiation control. Mutations of the PRKAR1A gene have been found in patients with Carney complex and in a minority of sporadic anaplastic thyroid carcinomas. The aim of the study was to retrospectively e...

GABAB (gamma-aminobutyric acid)-receptors have been implicated in central nervous system (CNS) functions, e.g. cognition and pain perception, and dysfunctions including spasticity and absence epilepsy. To permit an analysis of the two known GABAB-receptor splice variants GABAB-R1a (GB1a) and GABAB-R1b (GB1b), their distribution pattern has been differentiated in the rat brain, using Western blo...

OBJECTIVE Haplogroup I of male-specific region of the human Y chromosome is associated with 50% increased risk of coronary artery disease. It is not clear to what extent conventional cardiovascular risk factors and genes of the male-specific region may explain this association. APPROACH AND RESULTS A total of 1988 biologically unrelated men from 4 white European populations were genotyped usi...
