Androgens and estrogens stimulate ribosome biogenesis in prostate and breast cancer cells in receptor dependent manner

Ribosome biogenesis is a fundamental cellular process intimately linked to cell growth and proliferation, which is upregulated in most of cancers especially in aggressive cancers. In breast and prostate cancers steroid hormone receptor signalling is the principal stimulus for cancer growth and progression. Here we investigated the link between estrogen and androgen receptor signalling and the initial stage of ribosome biogenesis - transcription of rRNA genes. We have discovered that estrogen or androgen treatment can positively regulate rRNA synthesis in breast and prostate cancer cells respectively and that this effect is receptor dependent. This novel and interesting finding suggests a previously unidentified link between steroid hormone receptor signalling pathways and the regulation of ribosome biogenesis.

Effectiveness of Criminal Justice Liaison and Diversion Services for Offenders With Mental Disorders: A Review

Objective: The authors evaluated and synthesised the best-available evidence relating to the effectiveness of CJLD service models with respect to changes in mental health status and/or criminal recidivism.Methods: Research examining the effectiveness of CJLD services when compared to traditional Criminal Justice System (CJS) responses was reviewed and systematically appraised according to Campbell/Cochrane guidelines. Key outcomes included a reduction in offending and post-intervention changes in mental health. Results: Comprehensive searches of published and unpublished literature identified 6571 studies which varied considerably in terms of their methodological approach and overall quality. Ten studies met the inclusion criteria. The synthesised findings indicated that, when compared to traditional CJS outcomes, CJLD services appeared to be effective in terms of identifying MDOs and impacting positively on criminal justice and mental health outcomes.Conclusions: Although the evidence may be deemed to be moderate in terms of methodological rigour, overall, the findings suggest that CJLD services can be beneficial. The effectiveness of services depends upon the model of service delivery, the availability of community services and the engagement of MDOs.The successful implementation of CJLD services requires a clearer recognition of the importance of system of care principles.

Preparation of planar retinal specimens:verification by histology, mRNA profiling, and proteome analysis

Elucidation of the transcriptome and proteome of the normal retina will be difficult since it is comprised of at least 55 different cell types. However the characteristic layered cellular anatomy of the retina makes it amenable to planar sectioning, enabling the generation of enriched retinal cell populations. The aim of this study was to validate a reproducible method for preparing enriched retinal layers from porcine retina.

Botanical travel, climate and David Moore’s moral geographies of Europe

During his forty-year curatorship of the Royal Dublin Society's botanical gardens in Glasnevin (1838–1879), David Moore undertook a number of excursions to continental Europe. These served to deepen the networks of plant exchange between Dublin and other botanical institutions and allowed him to examine the relationships between climate, plant survivability and societal development. This paper focuses on two trips taken in the 1860s to Scandinavia and Iberia and charts how Moore situated his experience of these places within a climatic hermeneutic. Moore's understanding of northern and southern Europe was organized around a set of judgments about their relative backwardness or advancement with respect to his experience of home and was seen through the lens of a moral climatology. Moreover, his Scots Presbyterian background and his commitment to natural theology informed his interpretation of the landscapes he encountered in his excursions across Europe.
