Evasion from apoptosis is one of the hallmarks of cancer. X-linked inhibitor of apoptosis protein (XIAP) is known to modulate apoptosis by inhibiting caspases and ubiquitinating target proteins. XIAP is mainly found at the cytoplasm, but recent data link nuclear XIAP to poor prognosis in breast cancer. Here, we generated a mutant form of XIAP with a nuclear localization signal (XIAPNLS-C-term) and investigated the oncogenic mechanisms associated with nuclear XIAP in breast cancer. Our results show that cells overexpressing XIAPΔRING (RING deletion) and XIAPNLS-C-term exhibited XIAP nuclear localization more abundantly than XIAPwild-type. Remarkably, overexpression of XIAPNLS-C-term, but not XIAPΔRING, conferred resistance to doxorubicin and increased cellular proliferative capacity. Interestingly, Survivin and c-IAP1 expression were not associated with XIAP oncogenic effects. However, NFκB expression and ubiquitination of K63, but not K48 chains, were increased following XIAPNLS-C-term overexpression, pointing to nuclear signaling transduction. Consistently, multivariate analysis revealed nuclear, but not cytoplasmic XIAP, as an independent prognostic factor in hormone receptor-negative breast cancer patients. Altogether, our findings suggest that nuclear XIAP confers poor outcome and RING-associated breast cancer growth and chemoresistance.We recently reported that loss of calcium/calmodulin-dependent protein kinase kinase-2 (CAMKK2), a serine/threonine kinase activated by intracellular calcium, in mice leads to tissue-specific aberrant turnover of transferrin (TF), a receptor-mediated iron-transporter that supplies iron to tissues. Atglistatin ic50 Iron dyshomeostasis is associated with the pathogenesis of several diseases, making TF transport relevant to health. In this study, we used hemizygous CAMKK2 hypomorphic human endothelial cell (EA.hy926) clones to demonstrate that cells with reduced CAMKK2 exhibit increased TF uptake and transcytosis, and decreased intracellular trafficking to subcellular organelles compared to wild-type. The abnormal TF trafficking in CAMKK2 hypomorphic cells correlated with a reduction in intracellular iron content and defective glucose metabolism including glycolysis and mitochondrial respiration. CAMKK2 deficiency also caused reduction in GAPDH and VDAC1 protein level which correlated to defective bioenergetics function. These findings have identified a novel mechanistic link between abnormal calcium signaling, iron dyshomeostasis and metabolic dysfunction involving CAMKK2.Ceftriaxone is a beta-lactam antibiotic that increases the expression of the major glutamate transporter, GLT-1. As such, ceftriaxone ameliorates symptoms across multiple rodent models of neurological diseases and substance use disorders. However, the mechanism behind GLT-1 upregulation is unknown. The present review synthesizes this literature in order to identify commonalities in molecular changes. We find that ceftriaxone (200 mg/kg for at least two days) consistently restores GLT-1 expression in multiple rodent models of neurological disease, especially when GLT-1 is decreased in the disease model. The same dose given to healthy/drug-naive rodents does not reliably upregulate GLT-1 in any brain region except the hippocampus. Increased GLT-1 expression does not consistently arise from transcriptional regulation, and is likely to be due to trafficking changes. In addition to altered transporter expression, ceftriaxone ameliorates neuropathologies (e.g. tau, amyloid beta, cell death) and aberrant protein expression associated with a number of neurological disease models. Taken together, these results indicate that ceftriaxone remains a strong candidate for treatment of multiple disorders in the clinic.Bipolar disorders have an onset in late adolescence or early adulthood and patients may experience alternating episodes of mania and depression, with euthymic periods interspersed between these extremes of mood. Clinical research studies have shown that bipolar disorder patients exhibit disruptions in circadian and seasonal rhythms, even when they are symptom free. In addition, some bipolar patients display pronounced seasonal patterns in occurrence of manic and depressive episodes, time of year for disease onset, and age of onset. Several groups have emphasized the impact of seasonal changes in sunlight intensity on bipolar disorder, especially in locations farther from the equator. In this paper, we examine rate of change of solar insolation during the spring and fall in locations that vary in their distance from the equator and propose that seasonal changes in sunlight intensity may be tracked by the suprachiasmatic nucleus and affect disease onset and progression in seasonally susceptible bipolar patients.Childhood and adolescence represent a time notable for the emergence of many psychiatric disorders, where comorbidity and co-occurrence of symptoms are well-documented. However, it remains unclear whether there exists common brain structural disturbance across psychiatric disorders in youth. Here, we conduct a transdiagnostic meta-analysis of 132 structural neuroimaging experiments in youth consisting of multiple psychiatric diagnoses. Compared to healthy peers, youth psychiatric disorders are characterized by reduced grey matter volume (GMV) of amygdala and lateral orbitofrontal cortex and enhanced GMV of ventromedial prefrontal cortex and precuneus. These four regions were then subjected to functional connectivity and decoding analyses based on healthy participant datasets, allowing for a data-driven quantitative inference on psychophysiological functions. These regions and their networks mapped onto systems implicated in negative valence, positive valence, as well as social and cognitive functioning. Together, our findings are consistent with transdiagnostic models of psychopathology, uncovering common structural disturbance across youth psychiatric disorders, potentially reflecting an intermediate transdiagnostic phenotype in association with broad dimensions of youth psychopathology.Background Beta-lactoglobulin (BLG) is a bovine lipocalin in milk with innate defense function. It is not understood under which circumstances BLG is associated with tolerance or allergy towards milk. Objective Here we assessed the capacity of ligand-free (apo-) versus -loaded (holo-) BLG to protect mice against allergy using iron-quercetin as exemplary ligand, and studied the molecular mechanisms. Methods Binding of iron-quercetin into BLG was modeled and confirmed by spectroscopy and docking calculations. Serum IgE binding of milk allergic and tolerant children to apo- and holo-BLG was assessed. Mice were intranasally treated with apo- versus holo-BLG and after systemic challenge immunologically analysed. AhR activation was evaluated with reporter cells and Cyp1A1 expression. Treated human peripheral blood mononuclear cells and human mast cells were assessed by FACS and degranulation, respectively. Results Modelling predicted masking of major IgE and T cell epitopes of BLG by ligand-binding. In line, IgE binding of milk allergic children was reduced towards holo-BLG which also impaired degranulation of mast cells.
