  2019-09-11

  

  Chk1 and Chk2 are functionally redundant protein kinases that respond to checkpoint signals emanating from the phosphatidylinositol 3-kinase family members ATM (ataxia-telangiectasia mutated) and ATR (Ataxia-telangiectasia and Rad-3 related). A concerted research effort has revealed many mechanistic

  However, there are still some issues that remain poorly understood. For instance, how TGF-β modulates DDR2 expression and whether Smads participate in the regulation. How does DDR2 regulate the expression of PTHrP via Runx2? Is there any other kinase downstream of DDR2 participating in PTHrP regulat

  2019-09-10

  

  During host-cell interactions, G. intestinalis trophozoites up-regulate several cell-associated proteins, including high-cysteine membrane proteins (HCMPs) and variant surface proteins (VSPs) [8]. The parasite also releases around 200 proteins upon host-cell contact, including many proteases [9,10].

  Social interaction is known to be the main source of stress in human beings (Dickerson and Kemeny, 2004, Tamashiro et al., 2005). An animal model of social stress should closely mimic real-life situations in human life (Neisewander et al., 2012); in this context, social defeat in an agonistic encoun

  Multiple lines of evidence now indicate that mitochondrial decay is a fundamental factor that leads to alterations in energy metabolism in the aged heart (Hagen et al., 2002, Judge and Leeuwenburgh, 2007, Lesnefsky et al., 2001c). Nevertheless, the exact biochemical events that cause such an alterat

  Acetylcholinesterase and cholinergic signaling The concept of a synapse between a neuron and an innervated cell, and the receptors that mediated their interaction, was developed by Bernard, Ehrlich, Sherrington, Langley and others (see [7], [8], [9]. It was long debated whether transmission of ne

  Finally, we have determined for the first time that aromatase enzyme activity is necessary to observe IGF-1-dependent 9184 receptor activation. Neuroestrogen synthesis has been shown to be important for the maintenance of synaptic spine density in hippocampal slice cultures (Kretz et al., 2004) and

  2019-09-10

  

  The upregulation of PTGS1 and PTGS2 in late gestation in mares could be linked to the high levels of estrogens produced by the fetoplacental unit. Estrogens are thought to be effective stimulators of prostaglandin production by potentially up regulating PTGS2 expression. Although a recent publicatio

  Hepatocyte proliferation is accompanied by changing gene expression [1,2]. as two of the three estrogen receptors are transcription factors: Estrogen Receptor alpha (ERα) and ERβ [[3], [4], [5]]. The most potent ligand estradiol, binds to ERα/ERβ and exerts changing cognate gene transcription [5]. O

  Recent studies have shown that the extracellular regulated protein kinase 1 and 2 (ERK1 and ERK2), commonly referred to collectively as ERK 1/2, are members of the mitogen-activated protein kinase (MAPK) family. This family of kinases transport signals from the surface of the cell to the nucleus, th

  Introduction Breast cancer is a highly prevalent malignancy. There are some recognized risk factors for breast cancer, like early menarche or late menopause, which increase the length of the exposure to hormones, as a result of a higher number of ovarian cycles [1]. Moreover, there is evidence supp

  Moreover, in this study, weak expression of MT1 and MT2 was also detected in the oviduct muscular layers. Although there are no reports regarding the role of MT1 and MT2 in oviduct muscular layers, previous studies have demonstrated that melatonin plays an important role in the uterine contractility

  We also note that though the Deferiprone of the N-terminus in Ube2E1∆N46 or the mutations in Ube2E16KtoR enhanced their activity compared to the wild type, it failed to match Ube2D2 (Fig. 1). We concluded this difference to be multi-factorial as none of the Ube2E1∆N46 point mutants involving “Ub ba
