  Introduction Androgens have been shown to regulate several neural functions ranging from reproduction to mood and cognitive abilities. This property starts as early as the perinatal period, which is characterized by prenatal and postnatal surges of gonadal testosterone, and continues through pube

  Introduction The development and plasticity of synapses involve the timely recruitment of a plethora of proteins on both pre- and postsynaptic sides through ill-defined mechanisms. At excitatory synapses, two of the major proteins that are dynamically recruited postsynaptically are the Ca2+/calmo

  Discussion Elevated blood BCAA levels are a common feature of a developed pathophysiological state characterized by obesity and IR [4]. It has been suggested that this profile is part of a panel of biomarkers able to predict the onset of more severe complications like diabetes in humans [14]. In

  Introduction Alzheimer's disease (AD) is a neurodegenerative disorder and the leading cause of dementia. It is characterized by progressive and irreversible damage to different Cycloheximide areas, resulting in cognitive impairment and behavioral changes (O'Neill, 2013, De Strooper and Karran, 2

  While the mechanisms by which ALDH2 regulates cardiac responses to pathological stress remain unclear, the capillary rarefaction found in pressure-overloaded ALDH2 Tg hearts provides potential clues. Loss of capillary density and diminished endothelial function occur in pathological hypertrophy [46]

  Though, we have proved that VA could suppress hepatic gluconeogenesis, the mechanisms of VA on gluconeogenesis in vivo and in vitro remain unclear. AMP-activated protein kinase (AMPK), which is called an energy receptor enzyme, is widely expressed in liver and other tissues [23]. AMPK has become ano

  Discussion Mycobacterium tuberculosis infection is a main threat to mankind, with one third of the world population being infected. [9] Over nine million new cases of tuberculosis and two million deaths from this disease occur yearly worldwide. [10] The rising incidence of tuberculosis over the l

  Actin cytoskeleton in protrusion Pushing force driving membrane protrusion is generated by polymerizing ABT 724 trihydrochloride synthesis filaments organized either into branched networks or parallel bundles. Branched networks are assembled through Arp2/3 complex-dependent actin nucleation and

  Another significant group of 5α-reductase inhibitors is the steroidal 3-carboxylic BMS 195614 derivatives (relevant examples in Fig. 5), which were designed to mimic the putative enzyme-bound enolate intermediate. This was achieved by introducing sp2-hybridized centers at C3 and C4 and an anionic ca

  For both, the 17α-hydroxylation and 17, 20-lyase reactions, the heme iron center of P450 17A1 receives electron reducing equivalents from CPR. Both reactions require one pair of electrons and molecular oxygen for the conversion of the substrate into product in each catalytic cycle. However, the 17,2

  Introduction: the DNA damage response — important implications for tumour development and treatment Cells are invariably challenged by tens of thousands of lesions inflicted on their DNA everyday (Lindhal, 1993). This DNA damage can be caused exogenously by exposure to different types of radiation

  Several alterations have been or can be associated to the decreased tolerance of steatotic liver to I/R injury. Previous studies demonstrated that upregulation of the mitochondrial uncoupling protein-2 (UP2) is strictly related to the increase of I/R injury in steatotic liver [4]. UPR induction is c

  Besides Arg2 overexpression, our data revealed that AGEs could decrease eNOS mRNA levels, which is considered a significant cause for attenuated NO production and vasodilation. It was found recently that AGEs significantly reduce eNOS expression levels and NO bioavailability in human carotid artery

  Plant tissues were thought to be natural sources containing different types of antioxidant compounds (tocopherols, ascorbic acid, carotenoids, and phenolic compounds). As a general classification, antioxidants were grouped as vitamins (ascorbic acid, tocopherols), carotenoids (condensed tannins, xan

  It is worth noting that in S. cerevisiae, the control of two cell-cycle checkpoints requiring Mcm1 involves two very different mechanisms. At the G1/S transition, Mcm1 transactivation activity is inhibited by Yox1 and Yhp1 repressors, whose expression is periodically regulated through the cell cycle
