Inhibition of c-Abl kinase activity renders cancer cells highly sensitive to mitoxantrone.
... constitutively active c-Abl expression. This aberrant kinase activity results in enhanced proliferation, which can be inhibited with imatinib. Imatinib is an ATP-competitive inhibitor stabilizing inactive c-Abl conformation . The kinase activity of c-Abl is increased after DNA damage and then increases the activity of Atm and Atr . Treatment with imatinib ... (Promega, Madison, WI, USA). The luciferase activity was quantified with the aid of a hybrid capture luminometer (Digene, Gaithersburg, 2 August 2014 | Volume 9 | Issue 8 | e105526 Mitoxantrone and c-Abl Kinase Activity MD, USA). Luciferase readings were divided by WST-1 value to obtain normalized reporter activity. Statistics To evaluate differences ... is not able to alter these levels (Figure 2). Cells treated with 0.6 mM MX and 0.8 mM DXR increased the caspase activity 2.5 fold, whereas the MX + imatinib combination treatment increased the activity 4 fold.

Inhibition of DYRK1A activity in cell culture To evaluate the new harmine analogues for their capacity of inhibiting DYRK1A in cell culture experiments, we compared the effect of AnnH75 and other select compounds on the DYRK1A-catalysed phosphorylation of splicing factor 3b1 (SF3B1). Phosphorylation of SF3B1 on Thr434 closely reflects the cellular activity of
Identification of PPARgamma partial agonists of natural origin (II): in silico prediction in natural extracts with known antidiabetic activity.
... 11 extracts known to have antidiabetic activity. Six of these molecules are similar to molecules with described antidiabetic activity but whose mechanism of action is unknown. Therefore, it is plausible that these 12 molecules could be the bioactive molecules responsible, at least in part, for the antidiabetic activity of the extracts containing them. ... the increase of the insulin-stimulated glucose uptake through the action of PPARc. We also suggest plants with undescribed antidiabetic activity that may contain PPARc partial agonists and are related to plants with known antidiabetic activity. These plants represent a potential new source of antidiabetic extracts. In addition, the new PPARc partial agonists ... natural extracts were described previously as having antidiabetic activity (Table 2). These 11 extracts contained 12 molecules that we predict to be PPARc partial agonists (see Table 2 and Figure S1), therefore, it is plausible that they could contribute to the observed antidiabetic activity of their corresponding extracts. In fact, a search with 2 February

... response including PO activity. Their major issue with PO activity was that with long term storage, even in -70°C temperature, PO activity could be degraded or spontaneously activated. There is no question that PO activity plays a role in insect innate immunity, but it is very species specific. There is a debate about the relevance of PO activity as a proxy ... less PO activity , and in Hetaerina americana (Fabricius) the larger individuals with larger wing spots had higher levels of PO activity . In these circumstances, there is considerable variability in PO activity within species, some of which might relate to immunity either directly or indirectly .

Intra- and Interhemispheric Propagation of Electrophysiological Synchronous Activity and Its Modulation by Serotonin in the Cingulate Cortex of Juvenile Mice.
... the cerebral cortex is the generation of synchronized activity during normal sensory processing  and also during pathological conditions (e.g., seizures ). Disinhibition of the neocortex by blockers of GABAA receptors (bicuculline, picrotoxin) is especially effective in generating synchronous activity, both in vivo  and in vitro [19, 20, 21]. ... involving the generation and local propagation of this synchronized activity in motor cortical areas [18, 22, 23], including the propagation of epileptiform discharges across the corpus callosum [24, 25], there is still little information about the propagation of this kind of electrical activity in other cortical areas. Among other afferent systems, the ... velocities were within the same range as the propagation velocities described previously for epileptiform activity or interictal discharges induced by the block of GABAergic receptors , but were much faster than the propagation of epileptiform activity induced by bathing the slices in zero Mg2+ extracellular solution [52, 53], a condition in which

To evaluate the activity of mannanase variants produced in the Yarrowia lipolytica expression host, an in-house highthroughput method based on the reducing sugar assay  was adapted to assay mannanase activity in liquid culture. The results are interpreted in ... tested to confirm the enhancement of activity in liquid cultures, we finally selected four mutants of PaMan5A and one mutant of PaMan26A that displayed improved activity beyond the CV of wild-type mannanases (7.7 and 12.2%, respectively).

Effects of solar activity on noise in CALIOP profiles above the South Atlantic Anomaly
... 11-year cycle of solar activity (with a 1year lag). By analyzing the geographic distribution of noisy profiles, we are able to reproduce known findings about the SAA region. Over the considered period, it shifts westward by 0.3◦ year−1 , and changes in size by 6◦ meridionally and 2◦ zonally, becoming larger with weaker solar activity. All results are ... the SAA, which impacts the noise in CALIOP observations, is anticorrelated with the 11-year cycle of solar activity (with 1 year lag) (Fürst et al., 2009). This anticorrelation is due to heating of the exo- and thermosphere during maximum solar activity, which leads to a higher neutral density in the altitudes below affected by the SAA (e.g., Qian et ... al., 2006). This increases the absorption and deflection of trapped particles, resulting in a lower particle flux compared to when the solar activity is minimum (Dachev et al., 1999). Thus during maximum solar activity the flux of energetic particles below CALIOP is smaller. The 1-year lag reflects the time needed for the atmosphere to react to incoming

Nonetheless, pharmacological closure of K(ATP)-channels by tolbutamide can trigger electrical activity and GLP-1 secretion [4, 9, 17], and our model shows that although the exogenous K(ATP)-channels activity is very low, a further reduction is sufficient to allow electrical activity.

Results reported here now show for ... cells around the rete testis following Sertoli cell ablation would be consistent with the Sertoli cell-like activity of the rete epithelial cells seen in neonatal mice  and suggests that these cells may retain a degree of Sertoli cell functional activity beyond puberty.

LRRK2 kinase activity is dependent on LRRK2 GTP binding capacity but independent of LRRK2 GTP binding.
... phosphorylation activity for the T1348N mutant clearly allow us to conclude that the T1348N inhibits kinase activity. Taken together, these data show that the capacity for GDP/GTP binding is essential for LRRK2 kinase activity, but that the specific guanine nucleotide bound to LRRK2 ROC does not play a modulatory role on LRRK2 kinase activity. Therefore ... phosphorylation activity of LRRK2 is unchanged when the LRRK2 guanine nucleotide binding pocket is previously saturated with various nucleotides, in contrast to the greatly reduced activity measured for the guanine nucleotide binding site mutant T1348N. Interestingly, when nucleotides were incubated with cell lysates prior to purification of LRRK2, kinase activity ... Our data show that an intact ROCGTPase domain is required for LRRK2 kinase activity and that kinase activity remains unchanged upon direct application of GDP compared to GTP or non-hydrolyzable GTP analogues, reconciling discrepancies in previous reports. Results LRRK2 kinase activity of the affinity purified protein is not altered upon co-incubation
