    Abstract Current pharmacological treatments for bipolar disorder are inadequate and based on serendipitously discovered drugs often with limited efficacy, burdensome side-effects, and unclear mechanisms of action. Advances in drug development for the treatment of bipolar disorder remain incremental and have come largely from repurposing drugs used for other psychiatric conditions, a strategy that has failed to find truly revolutionary therapies, as it does not target the mood instability that characterises the condition. The lack of therapeutic innovation in the bipolar disorder field is largely due to a poor understanding of the underlying disease mechanisms and the consequent absence of validated drug targets. A compelling new treatment target is the Ca

    Abstract This article highlights studies published during the past year that represent significant scientific achievements in the world of calmodulin kinase cascades. Calmodulin is the primary receptor for calcium present in all cells. The binding of its calcium ligand results in a conformational change in calmodulin, which allows the calcium-calmodulin complex to interact with many different targets. In the studies to be summarized in this review, the particular calmodulin cascade involved is shown to be the pathway responsible for important biological responses, including long-term memory formation, dendritic cell survival, hypercapnia, neuronal migration, synapse formation, autophagy, fatty acid oxidation, and energy balance. In some cases, the pathway was previously unknown, and the identification of the calmodulin cascade represents the definition of roles. In other cases, manipulating the cascade has suggested therapeutic approaches to certain diseases, most significantly, type 2 diabetes and obesity.

    Abstract Calcium (Ca(2+)) is an essential ligand that binds its primary intracellular receptor calmodulin (CaM) to trigger a variety of downstream processes and pathways. Central to the actions of Ca(2+)/CaM is the activation of a highly conserved Ca(2+)/CaM kinase (CaMK) cascade that amplifies Ca(2+) signals through a series of subsequent phosphorylation events. Proper regulation of Ca(2+) flux is necessary for whole-body metabolism and disruption of Ca(2+) homeostasis has been linked to various metabolic diseases. Here we provide a synthesis of recent advances that highlight the roles of the Ca(2+)/CaMK axis in key metabolic tissues. An appreciation of this information is critical to understanding the mechanisms by which Ca(2+)/CaM-dependent signaling contributes to metabolic homeostasis and disease.

    Abstract Many cellular Ca(2+)-dependent signaling cascades utilize calmodulin (CaM) as the intracellular Ca(2+) receptor. Ca(2+)/CaM binds and activates a plethora of enzymes, including CaM kinases (CaMKs). CaMKK2 is one of the most versatile of the CaMKs and will phosphorylate and activate CaMKI, CaMKIV, and AMP-activated protein kinase. Cell expression of CaMKK2 is limited, yet CaMKK2 is involved in regulating many important physiological and pathophysiological processes, including energy balance, adiposity, glucose homeostasis, hematopoiesis, inflammation, and cancer. Here, we explore known functions of CaMKK2 and discuss its potential as a target for therapeutic intervention.

    Abstract Aristida beyrichiana (wiregrass) is a foundation bunchgrass species in many southeastern U.S. native pine communities, but it has been dramatically reduced in extent. The potential for reintroduced wiregrass to reproduce and spread is not well studied because of its slow growth and limited conditions for successful reproduction. We present a case study where tussocks of wiregrass were transplanted and recensused 18 and 37 years later to study their population dynamics. We remeasured a subset of tussocks to estimate diameter growth over 2 years. With frequent prescribed fires (1–3 year intervals, about half in April–July when flowering is induced), the initial population of 160 tussocks increased to 1,199 through seed dispersal and clonal fragmentation, and the total basal area approximately tripled. Relationships among tussock density, diameter, and basal area per m² and their changes over time suggest density‐dependent regulation of population structure, possibly from intraspecific competition and competitive exclusion. Tussock diameter growth averaged 0.9 cm per year over a 2‐year period and was independent of initial diameter. This study, the longest of a wiregrass population to date, suggests that a low‐density population established in native soil types has a slow but robust tendency to reproduce by seed and expand if provided frequent fire, including April–July burns, in a high light environment without soil disturbance. Wiregrass can be characterized as a competitive, late‐successional, dominant species in stable, climax‐like native savannas, promising long‐term success under appropriate conditions as part of restoration efforts.

    Abstract Objective: The liver is the primary internal metabolic organ that coordinates whole body energy homeostasis in response to feeding and fasting. Genetic ablation or pharmacological inhibition of calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) has been shown to significantly improve hepatic health and peripheral insulin sensitivity upon overnutrition with high fat diet. However, the precise molecular underpinnings that explain this metabolic protection have remained largely undefined.
    Methods: To characterize the role of CaMKK2 in hepatic metabolism, we developed and challenged liver-specific CaMKK2 knockout (CaMKK2
    Results: Consistent with previous findings, we show that hepatic CaMKK2 ablation significantly improves indices of peripheral insulin sensitivity. Mechanistically, we found that CaMKK2 phosphorylates and regulates GAPDH to promote glucose metabolism and PEX3 to blunt peroxisomal fatty acid catabolism in the liver.
    Conclusion: CaMKK2 is a central metabolic fuel sensor in the liver that significantly contributes to whole body systems metabolism.

    Abstract Hematopoietic stem cells (HSC) are a relatively quiescent pool of cells that perform the arduous task of replacing the short-lived mature cells of the peripheral blood. While a rapid expansion of HSCs under periods of hematological stress is warranted, their enhanced proliferation during homeostasis leads to loss of function. We recently reported that in HSCs, the evolutionarily conserved growth factor erv1-like (Gfer) acts to counter jun activation domain-binding protein 1 (Jab1)-mediated nuclear export and destabilization of the cell cycle inhibitor, p27kip1, by directly binding to and sequestering the COP9 signalosome (CSN) subunit. Through this mechanism, Gfer promotes quiescence and maintains the functional integrity of HSCs. Here, we extend our study to demonstrate an association between Gfer and Ca2+/calmodulin-dependent protein kinase IV (CaMKIV) in the regulation of HSC proliferation. Highly proliferative and functionally deficient Camk4-/- HSCs possess significantly lower levels of Gfer and p27kip1. Ectopic expression of Gfer restores quiescence and elevates p27kip1 expression in Camk4-/- HSCs. These results further substantiate a critical role for Gfer in the restriction of unwarranted proliferation in HSCs through the inhibition of Jab1 and subsequent stabilization and nuclear retention of p27kip1. This Gfer-mediated pro-quiescence mechanism could be therapeutically exploited in the treatment of hematological malignancies associated with elevated Jab1 and reduced p27kip1.
