Requirement of circadian genes for cocaine sensitization in Drosophila. (1/96)

The circadian clock consists of a feedback loop in which clock genes are rhythmically expressed, giving rise to cycling levels of RNA and proteins. Four of the five circadian genes identified to date influence responsiveness to freebase cocaine in the fruit fly, Drosophila melanogaster. Sensitization to repeated cocaine exposures, a phenomenon also seen in humans and animal models and associated with enhanced drug craving, is eliminated in flies mutant for period, clock, cycle, and doubletime, but not in flies lacking the gene timeless. Flies that do not sensitize owing to lack of these genes do not show the induction of tyrosine decarboxylase normally seen after cocaine exposure. These findings indicate unexpected roles for these genes in regulating cocaine sensitization and indicate that they function as regulators of tyrosine decarboxylase.  (+info)

double-time is identical to discs overgrown, which is required for cell survival, proliferation and growth arrest in Drosophila imaginal discs. (2/96)

We have isolated the discs overgrown gene of Drosophila and shown that it encodes a homolog of the Casein kinase I(delta)/(epsilon) subfamily and is identical to the double-time gene. However, in contrast to the weak double-time alleles, which appear to affect only the circadian rhythm, discs overgrown alleles, including bona fide null alleles, show strong effects on cell survival and growth control in imaginal discs. Analysis of their phenotypes and molecular lesions suggests that the Discs overgrown protein is a crucial component in the mechanism that links cell survival during proliferation to growth arrest in imaginal discs. This work provides the first analysis in a multicellular organism of Casein kinase I(delta)/(epsilon) functions necessary for survival. Since the amino acid sequences and three-dimensional structures of Casein kinase I(delta)/(epsilon) enzymes are highly conserved, the results suggest that these proteins may also function in controlling cell growth and survival in other organisms.  (+info)

Two novel doubletime mutants alter circadian properties and eliminate the delay between RNA and protein in Drosophila. (3/96)

Phosphorylation is an important feature of pacemaker organization in Drosophila. Genetic and biochemical evidence suggests involvement of the casein kinase I homolog doubletime (dbt) in the Drosophila circadian pacemaker. We have characterized two novel dbt mutants. Both cause a lengthening of behavioral period and profoundly alter period (per) and timeless (tim) transcript and protein profiles. The PER profile shows a major difference from the wild-type program only during the morning hours, consistent with a prominent role for DBT during the PER monomer degradation phase. The transcript profiles are delayed, but there is little effect on the protein accumulation profiles, resulting in the elimination of the characteristic lag between the mRNA and protein profiles. These results and others indicate that light and post-transcriptional regulation play major roles in defining the temporal properties of the protein curves and suggest that this lag is unnecessary for the feedback regulation of per and tim protein on per and tim transcription.  (+info)

Short-period mutations of per affect a double-time-dependent step in the Drosophila circadian clock. (4/96)

Circadian (24 hour) PERIOD (PER) protein oscillation is dependent on the double-time (dbt) gene, a casein kinase Ivarepsilon homolog [1-3]. Without dbt activity, hypophosphorylated PER proteins over-accumulate, indicating that dbt is required for PER phosphorylation and turnover [3,4]. There is evidence of a similar role for casein kinase Ivarepsilon in the mammalian circadian clock [5,6]. We have isolated a new dbt allele, dbt(ar), which causes arrhythmic locomotor activity in homozygous viable adults, as well as molecular arrhythmicity, with constitutively high levels of PER proteins, and low levels of TIMELESS (TIM) proteins. Short-period mutations of per, but not of tim, restore rhythmicity to dbt(ar) flies. This suppression is accompanied by a restoration of PER protein oscillations. Our results suggest that short-period per mutations, and mutations of dbt, affect the same molecular step that controls nuclear PER turnover. We conclude that, in wild-type flies, the previously defined PER'short domain' [7,8] may regulate the activity of DBT on PER.  (+info)

Phosphorylation of period is influenced by cycling physical associations of double-time, period, and timeless in the Drosophila clock. (5/96)

The clock gene double-time (dbt) encodes an ortholog of casein kinase Iepsilon that promotes phosphorylation and turnover of the PERIOD protein. Whereas the period (per), timeless (tim), and dClock (dClk) genes of Drosophila each contribute cycling mRNA and protein to a circadian clock, dbt RNA and DBT protein are constitutively expressed. Robust circadian changes in DBT subcellular localization are nevertheless observed in clock-containing cells of the fly head. These localization rhythms accompany formation of protein complexes that include PER, TIM, and DBT, and reflect periodic redistribution between the nucleus and the cytoplasm. Nuclear phosphorylation of PER is strongly enhanced when TIM is removed from PER/TIM/DBT complexes. The varying associations of PER, DBT and TIM appear to determine the onset and duration of nuclear PER function within the Drosophila clock.  (+info)

The Drosophila double-timeS mutation delays the nuclear accumulation of period protein and affects the feedback regulation of period mRNA. (6/96)

The Drosophila double-time (dbt) gene, which encodes a protein similar to vertebrate epsilon and delta isoforms of casein kinase I, is essential for circadian rhythmicity because it regulates the phosphorylation and stability of period (per) protein. Here, the circadian phenotype of a short-period dbt mutant allele (dbt(S)) was examined. The circadian period of the dbt(S) locomotor activity rhythm varied little when tested at constant temperatures ranging from 20 to 29 degrees C. However, per(L);dbt(S) flies exhibited a lack of temperature compensation like that of the long-period mutant (per(L)) flies. Light-pulse phase-response curves were obtained for wild-type, the short-period (per(S)), and dbt(S) genotypes. For the per(S) and dbt(S) genotypes, phase changes were larger than those for wild-type flies, the transition period from delays to advances was shorter, and the light-insensitive period was shorter. Immunohistochemical analysis of per protein levels demonstrated that per protein accumulates in photoreceptor nuclei later in dbt(S) than in wild-type and per(S) flies, and that it declines to lower levels in nuclei of dbt(S) flies than in nuclei of wild-type flies. Immunoblot analysis of per protein levels demonstrated that total per protein accumulation in dbt(S) heads is neither delayed nor reduced, whereas RNase protection analysis demonstrated that per mRNA accumulates later and declines sooner in dbt(S) heads than in wild-type heads. These results suggest that dbt can regulate the feedback of per protein on its mRNA by delaying the time at which it is translocated to nuclei and altering the level of nuclear PER during the declining phase of the cycle.  (+info)

The doubletime and CKII kinases collaborate to potentiate Drosophila PER transcriptional repressor activity. (7/96)

In all genetically studied model organisms, a negative feedback loop of gene expression contributes to the circadian rhythm mechanism. In the Drosophila system, it has been proposed that the delay between the synthesis and function of clock proteins is due to phosphorylation-regulated nuclear entry. To test this hypothesis, we assayed the relationship between PER phosphorylation, nuclear localization, and transcriptional repression activity in cultured S2 cells. The results indicate that the two putative PER kinases DBT and CKII work together to phosphorylate PER and increase repression activity. Experiments combining kinase inhibition with inhibition of PER nuclear export suggest that phosphorylation directly affects PER repression activity and that PER nuclear localization is an indirect consequence of the association of active PER with DNA or chromatin. This interpretation suggests further that the circadian regulation of PER nuclear localization in flies reflects changes in PER transcriptional activity rather than in PER nuclear import or export activity.  (+info)

Casein kinase Iepsilon modulates the signaling specificities of dishevelled. (8/96)

Wnt signaling is critical to many aspects of development, and aberrant activation of the Wnt signaling pathway can cause cancer. Dishevelled (Dvl) protein plays a central role in this pathway by transducing the signal from the Wnt receptor complex to the beta-catenin destruction complex. Dvl also plays a pivotal role in the planar cell polarity pathway that involves the c-Jun N-terminal kinase (JNK). How functions of Dvl are regulated in these two distinct pathways is not clear. We show that deleting the C-terminal two-thirds of Dvl, which includes the PDZ and DEP domains and is essential for Dvl-induced JNK activation, rendered the molecule a much more potent activator of the beta-catenin pathway. We also found that casein kinase Iepsilon (CKIepsilon), a previously identified positive regulator of Wnt signaling, stimulated Dvl activity in the Wnt pathway, but dramatically inhibited Dvl activity in the JNK pathway. Consistent with this, overexpression of CKIepsilon in Drosophila melanogaster stimulated Wnt signaling and disrupted planar cell polarity. We also observed a correlation between the localization and the signaling activity of Dvl in the beta-catenin pathway and the JNK pathway. Furthermore, by using RNA interference, we demonstrate that the Drosophila CKIepsilon homologue Double time positively regulates the beta-catenin pathway through Dvl and negatively regulates the Dvl-induced JNK pathway. We suggest that CKIepsilon functions as a molecular switch to direct Dvl from the JNK pathway to the beta-catenin pathway, possibly by altering the conformation of the C terminus of Dvl.  (+info)

When processors get too hot to work properly, they reduce their clock speed and operating voltage. In order to protect the CPU and motherboard from getting fried, the processors either reduce their computing speed or even shut off completely. Until now, cooling elements and fans are used to avoid overheating the heat-sensitive components. The researchers found a way to cool processors from the top as well as from below using a liquid-based cooling system.. The research team reports that the innovation can achieve a significant increase in performance. The scientists have also integrated passive elements for voltage regulators, photonic ICs, and optical waveguides into the interposer. This enables highly effective cooling and therefore higher performance. For this purpose, microchannel structures with tightly sealed vias are installed in the silicon interposer, which is located between the processor and the printed circuit board..

Genetic mutations that cause an inherited sleep disorder also appear to be linked to migraine, scientists have found.. The mutations are rare, but lead researcher Louis Ptáček, professor of neurology at the University of California, San Francisco, says the study moves scientists one step closer to understanding the molecular pathway to pain in migraine. Migraine is common, affecting one in four women and one in 12 men in the UK. Yet the condition is not well understood and, Professor Ptáček says, the need for better treatments is huge.. The mutations are in a gene called casein kinase I delta (CKIdelta), which has many functions, including helping control the bodys internal clock. CKIdelta mutations cause an unusual sleep pattern of early sleep times and early rising. Work on two families with this sleep disorder suggested to researchers that CKIdelta mutations were also associated with migraines.. They investigated this link using mice carrying one of the CKIdelta mutations. ...

An apparatus and method for providing a data eye monitor. The data eye monitor apparatus utilizes an inverter/latch string circuit and a set of latches to save the data eye for providing an infinite persistent data eye. In operation, incoming read data signals are adjusted in the first stage individually and latched to provide the read data to the requesting unit. The data is also simultaneously fed into a balanced XOR tree to combine the transitions of all incoming read data signals into a single signal. This signal is passed along a delay chain and tapped at constant intervals. The tap points are fed into latches, capturing the transitions at a delay element interval resolution. Using XORs, differences between adjacent taps and therefore transitions are detected. The eye is defined by segments that show no transitions over a series of samples. The eye size and position can be used to readjust the delay of incoming signals and/or to control environment parameters like voltage, clock speed and

Context. A significant percentage of massive stars are found in multiple systems. The effect of binarity on stellar evolution is poorly constrained. In particular, the role of tides and mass transfer on surface chemical abundances is not constrained observationally. Aims: The aim of this study is to investigate the effect of binarity on the stellar properties and surface abundances of massive binaries. Methods: We performed a spectroscopic analysis of six Galactic massive binaries. We obtained the spectra of individual components via a spectral disentangling method and subsequently analyzed these spectra by means of atmosphere models. The stellar parameters and CNO surface abundances were determined. Results: Most of these six systems are comprised of main-sequence stars. Three systems are detached, two are in contact, and no information is available for the sixth system. For 11 out of the 12 stars studied, the surface abundances are only mildly affected by stellar evolution and mixing. The surface

The 3rd generation OMAP, the OMAP 3[6] is broken into 3 distinct groups: the OMAP34x, the OMAP35x, and the OMAP36x. OMAP34x and OMAP36x are distributed directly to large handset (such as cell phone) manufacturers. OMAP35x is a variant of OMAP34x intended for catalog distribution channels. The OMAP36x is a 45 nm version of the 65 nm OMAP34x with higher clock speed.[7]. The OMAP 3611 found in devices like the Bookeens Cybook Odyssey is a licensed crippled version of the OMAP 3621, both are the same silicon (as marking are the same) but officially the 3611 was sold to be only able to drive e-Ink screen and does not have access to IVA & DSP. The video technology in the higher end OMAP 3 parts is derived in part from the DaVinci product line, which first packaged higher end C64x+ DSPs and image processing controllers with ARM9 processors last seen in the older OMAP 1 generation or ARM Cortex-A8.[8]. Not highlighted in the list below is that each OMAP 3 SoC has an Image, Video, Audio (IVA2) ...
MIT physicists discover a new physical phenomenon that could eventually lead to the first increases in computers clock speed since 2002.
The milk-derived protein human Casein alpha s1 (CSN1S1) has recently been detected in blood cells and was shown to possess proinflammatory properties. In the present study, we investigated the effect of CSN1S1 on the differentiation of monocytes. Primary human monocytes were stimulated with recombinant CSN1S1 and compared to cells stimulated with GM-CSF/IL-4 or M-CSF/IFNγ. Morphological changes were assessed by microscopy and quantification of surface markers of differentiation by FACS analysis. Phagocytic activity of CSN1S1 stimulated cells was measured by quantification of zymosan labeled particle uptake. The role of mitogen activated protein kinases for CSN1S1-induced differentiation of monocytes and proinflammatory cytokine expression was assessed by supplementation of specific inhibitors. CSN1S1 at a concentration of 10 μg/ml resulted in morphological changes (irregular shape, pseudopodia) and aggregation of cells, comparable to changes observed in M-CSF/IFNγ differentiated macrophages.

La caseína quinasa 2, alfa 1 (EC 2.7.11.1) es una enzima codificada en humanos por el gen HGNC CSNK2A1 .[1]​[2]​ La caseína quinasa 2 es una serina/treonina quinasa que fosforila proteínas ácidas como la caseína. Esta proteína se dispone en forma de tetrámero y se compone de una subunidad alfa, una alfa prima y dos subunidades beta. La subunidad alfa contiene el sitio de actividad catalítica mientras que la subunidad beta se encarga de la autofosforilación. El gen CSNK2A1 codifica la subunidad alfa de este complejo y se localiza en el cromosoma 20, aunque se han descrito pseudogenes relacionados en el cromosoma 11. Se han encontrado tres variantes transcripcionales del gen que codifican dos isoformas diferentes de la proteína.[3]​ ...

As a more challenging example, let us consider the Blowfly model proposed by Wood (2010): \[ N_{t} = R_t + S_t, \] where \[ R_t \sim \text{Pois}(PN_{t-\tau}e^{-\frac{N_{t-\tau}}{N_0}}e_t), \] represents delayed recruitment process, while: \[ S_t \sim \text{binom}(e^{-\delta\epsilon_t}, N_{t-1}), \] denotes the adult survival process. Finally \(e_t\) and \(\epsilon_t\) are independent gamma distributed random variables, with unit means and variances equal to \(\sigma_p^2\) and \(\sigma_d^2\) respectively. We start by creating a ...
A well-known result, due to Ostrowski, states that if $\Vert P-Q \Vert_2< \varepsilon$, then the roots $(x_j)$ of $P$ and $(y_j)$ of $Q$ satisfy $,x_j -y_j,\le C n \varepsilon^{1/n}$, where $n$ is the degree of $P$ and $Q$. Though there are cases where this estimate is sharp, it can still be made more precise in general, in two ways: first by using Bombieris norm instead of the classical $l_1$ or $l_2$ norms, and second by taking into account the multiplicity of each root. For instance, if $x$ is a simple root of $P$, we show that $,x-y,< C \varepsilon$ instead of $\varepsilon^{1/n}$. The proof uses the properties of Bombieris scalar product and Walsh Contraction Principle ...
