Abstract: The mammalian TOR (mTOR) pathway integrates nutrient- and growth factor-derived signals to regulate growth, the process whereby cells accumulate mass and increase in size. mTOR is a large protein kinase and the target of rapamycin, an immunosuppressant that also blocks vessel restenosis and has potential anticancer applications. mTOR interacts with the raptor and GbetaL proteins to form a complex that is the target of rapamycin. Here, we demonstrate that mTOR is also part of a distinct complex defined by the novel protein rictor (rapamycin-insensitive companion of mTOR). Rictor shares homology with the previously described pianissimo from D. discoidieum, STE20p from S. pombe, and AVO3p from S. cerevisiae. Interestingly, AVO3p is part of a rapamycin-insensitive TOR complex that does not contain the yeast homolog of raptor and signals to the actin cytoskeleton through PKC1. Consistent with this finding, the rictor-containing mTOR complex contains GbetaL but not raptor and it neither regulates the mTOR effector S6K1 nor is it bound by FKBP12-rapamycin. We find that the rictor-mTOR complex modulates the phosphorylation of Protein Kinase C alpha (PKCalpha) and the actin cytoskeleton, suggesting that this aspect of TOR signaling is conserved between yeast and mammals..

Abstract: The medial prefrontal cortex (mPFC) plays a critical role in cocaine addiction. However, evidence to elucidate how the mPFC is functionally involved in cocaine addiction remains incomplete. Recent studies have revealed that repeated cocaine administration induces various neuroadaptations in pyramidal mPFC neurons, including a reduction in voltage-gated K+ currents (VGKCs) and a possible increase in voltage-sensitive Ca2+ currents (I(Ca)). Here, we performed both current-clamp recordings in brain slices and voltage-clamp recordings in freshly dissociated cells to determine whether I(Ca) is altered in mPFC pyramidal neurons after chronic cocaine treatment with a short-term or long-term withdrawal. In addition, a critical role of VGKCs in regulating the generation of Ca2+ plateau potential was also studied in mPFC neurons. Repeated cocaine administration significantly prolonged the duration of evoked Ca2+ plateau potentials and increased the whole-cell I(Ca) in mPFC neurons after a 3 d withdrawal. Selective blockade of L-type Ca2+ channels by nifedipine not only significantly increased the threshold but also reduced the duration and amplitude of Ca2+ plateau potentials in both saline- and cocaine-withdrawn mPFC neurons. However, there was no significant difference in the increased threshold, reduced duration, and decreased amplitude of Ca2+ potentials between saline- and cocaine-withdrawn neurons after blockade of L-type Ca2+ channels. Moreover, an increase in amplitude was also observed, whereas the prolonged duration persisted, in Ca2+ potentials after 2-3 weeks of withdrawal. These findings indicate that chronic exposure to cocaine facilitates the responsiveness of I(Ca), particularly via the activated L-type Ca2+ channels, to excitatory stimuli in rat mPFC pyramidal neurons..

Abstract: With respect to cervical cancer management, Finland and the Netherlands are comparable in relevant characteristics, e.g., fertility rate, age-of-mother at first birth and a national screening programme for several years. The aim of this study is to compare trends in incidence of and mortality from cervical cancer in Finland and the Netherlands in relation to the introduction and intensity of the screening programmes. Therefore, incidence and mortality rates were calculated using the Cancer Registries of Finland and the Netherlands. Data on screening intensity were obtained from the Finnish Cancer Registry and the Dutch evaluation centre at ErasmusMC-Rotterdam. Women aged 30-60 have been screened every 5 years, in Finland since 1992 and in the Netherlands since 1996. Screening protocols for smear taking and referral to the gynaecologist are comparable. Incidence and mortality rates have declined more in Finland. In 2003, age-adjusted incidence and mortality in Finland were 4.0 and 0.9 and in the Netherlands 4.9 and 1.4 per 100,000 woman-years, respectively. Excess smear use in the Netherlands was estimated to be 24 per 1,000 women during a 5-year interval compared to 121 in Finland. The decline in mortality in Finland seems to be almost completely related to the screening programme whereas in the Netherlands it was initially considered to be a natural decline. Differences in risk factors might also play a role: the Netherlands has higher population density and higher percentages of immigrants and (female) smokers. The greater excess smear use in Finland might also have affected incidence.. Title: Transcriptional profiling of the heart reveals chamber-specific gene expression patterns.
