Serum Glutamate Levels Correlate with Gleason Score and Glutamate Blockade Decreases Proliferation, Migration, and Invasion and Induces Apoptosis in Prostate Cancer Cells
During glutaminolysis, glutamine is catabolized to glutamate and incorporated into citric acid cycle and lipogenesis. Serum glutamate levels were measured in patients with primary prostate cancer (PCa) or metastatic castrate-resistant PCa (mCRPCa) to establish clinical relevance. The effect of glutamate-deprivation or blockade by metabotropic glutamate receptor 1 (GRM1)-antagonists was investigated on PCa cells’ growth, migration, and invasion to establish biological relevance
stall-Mediated Extrinsic Control of Ovarian Follicle Formation in Drosophila
Complex patterns of morphogenesis require intricate coordination of multiple, regulatory processes that control cellular identities, shapes, and behaviors, both locally and over vast distances in the developing organism or tissue. Studying Drosophila oogenesis as a model for tissue morphogenesis, we have discovered extraovarian regulation of follicle formation. Clonal analysis and ovary transplantation have demonstrated that long-range control of follicle individualization requires stall gene function in cells outside of the ovary. Although tissue nonautonomous regulation has been shown to govern follicle maturation and survival, this is the first report of an extraovarian pathway involved in normal follicle formation

Things fall apart? Discourses on agency and change in organizations
The history of the concept of ‘agency’ in organizational theory over the
last 50 years makes dismal reading. From a position of unbounded
optimism that organizational change could be managed as a rational or
planned process with a transparent agenda, we now confront restructured
workplaces characterized by new forms of flexibility, hypercomplexity
and chaos in which the nature, sources and consequences
of change interventions have become fundamentally problematic. How
did this occur and what implications does it have for our understanding
of agency and change in organizations? Should we assume that
rationalist concepts of centred agency are no longer viable, or should
we welcome the plural and promising new forms of decentred agency
emerging within organizations? This article presents a selective interdisciplinary
history of competing disciplinary discourses on agency and
change in organizations, classified into rationalist, contextualist, dispersalist
and constructionist discourses. Although the four discourses clarify the
meta-theoretical terrain of agency in relation to organizational change
theories, the growing plurality of discourses challenges the social scientific ambitions of the research field to be objective, cumulative or unified. It is concluded that the future for research on agency and change in organizations is characterized by new opportunities for empirical investigation and intervention, but also by mounting threats to the epistemological rationale of objective knowledge and the efficacy of practice
