  Several studies have already shown that mPR activation can significantly reduce intracellular cAMP levels in different kind of cells, such as GT1-7 neuronal cells [32], MDA-MB-468 breast cancer cells [55] and primary vascular endothelial cells [56]. The experiments performed with PTXa and 8-Br-cAMP

  2020-02-25

  

  In the frontal cortex, the present study found a relationship between working memory performance and activated Erk2 expression for the E2-only group, where animals that tended to perform better on the WMC measure tended to have higher activated Erk2 expression. This suggests that there is a unique r

  2020-02-25

  

  At one time, the biological effects of cAMP were thought to be mediated exclusively by Protein Kinase A (PKA). Consistent with this, PKA inhibitors have been shown to reverse the effects of cAMP-elevating agents on VSMC proliferation [5]. However, we recently reported that cAMP-mediated inhibition o

  2020-02-25

  

  In addition to vasoconstrictor actions (acute effects), ET-1 exerts potent mitogenic actions on vascular smooth muscle cells and cardiac myocytes (chronic effects), hence causing vascular and cardiac hypertrophy [19,24,25]. These effects are mediated via stimulation of either ETA or ETB receptors, a

  2020-02-24

  

  The fibrillogenesis process of collagen is understood to initiate in the extracellular space near the plasma membrane where secretory vesicles form regions of deep invagination. However, it is not clear how and when collagen-binding proteins interact with collagen molecules during fibrillogenesis or

  2020-02-24

  

  Several large-scale clinical studies have set out with the common goal to further understand the cognitive impact of menopause and hormone therapies taken by women (Gleason et al., 2015, Greendale et al., 2011, Karlamangla et al., 2017, Rapp et al., 2003, Shumaker et al., 2003). Only one human study

  The ADME profile of AAT-008 () was very promising, with high stability in HLM. The pre-clinical pharmacokinetic properties of AAT-008 were also assessed in rats (Sprague-Dawley, male), dogs (beagle, male), and monkeys (cynomolgus, male). The experimentally determined parameters are summarized in .

  2020-02-24

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fami

  2020-02-24

  

  The IP3R is a ubiquitously expressed Ca2+-release channel from the ER, activated by IP3, produced upon cellular stimulation by hormones, growth factors or neurotransmitters. Three genes are coding for the IP3R and their gene products (IP3R1, IP3R2, IP3R3) assemble in functional homo- or heterotetram

  2020-02-24

  

  Despite its significance in tumor suppression, the molecular mechanism by which DAPK is regulated and its interplay with other tumor suppressors and oncoproteins have not been completely unraveled. Although primarily regulated by CaM binding (Cohen et al., 1997), DAPK activity can also be modulated

  Eukaryotic cell cycle machinery is thought to appropriately modulate cell proliferation and cell expansion in various developmental stages and environmental conditions. The core feature of cell-cycle control is the fluctuation of CDK activity, which is regulated by three interactive and conserved me

  Within their range of applicability, both approaches matched the phase boundaries and yields generally to within the measurement error. The approaches matched the phase compositions generally to within 11 wt% or less with the average absolute deviations listed below: One advantage of the proposed a

  Early developments Historically, the advent of SMEPT can be traced to the 1980′s, where the first example of localized prodrug conversion was achieved using a judiciously placed enzyme – in order to achieve a localized feed of 5-fluorouracil (5-FU). Immobilization of E. coli-derived cytosine deam

  During DNA replication p21 protein binds PCNA, in its role as processivity factor, to stop replication when there is DNA damage, and apparently p21 also binds PCNA when this is in complex with Cyc/CDKs [11]. In plants, KRPs (functional analogs of p21), inhibit kinase activity in CycD/CDKs complexes
