Cancer stem cells are responsible for tumor recurrence and metastasis. A new highly reproducible procedure for human breast cancer MCF-7 stem cells (BCSC) isolation and selection was developed by using a combination of hypoxia/hypoglycemia plus taxol and adriamycin for 24h. The BCSC enriched fraction (i) expressed (2-15 times) the typical stemness protein markers CD44+, ALDH1A3 and Oct 3/4; (ii) increased its clonogenicity index (20-times), invasiveness profile (>70%), migration capacity (100%) and ability to form mammospheres, compared to its non-metastatic MCF-7 counterpart...

OBJECTIVE: Detection of Alzheimer's disease (AD) prior to clinical inception will be paramount for introducing disease modifying treatments. We have begun collecting baseline characteristics of a community cohort for longitudinal assessment and testing of antecedent blood-based biomarkers. We describe the baseline visit from the first 131 subjects in relationship to a commonly described cytokine, interleukin 6 (IL-6). METHODS: Subjects from the community presented for a free memory screening with varying degrees of memory concern...

BACKGROUND: Although inflammatory cytokines are established biomarkers of mood disorders, their molecular mechanism is not known. We hypothesized that circulating mitochondrial DNA (mtDNA) contributes to inflammation and could be used as biomarkers. We investigated if circulating mtDNA level is associated with inflammatory cytokines and can be used as a biomarker of mood disorders. METHODS: Plasma mtDNA concentration was measured with real-time quantitative PCR targeting two regions of the mtDNA and plasma levels of four cytokines (GM-CSF, IL-2, IL-4, and IL-6) were measured with a multiplex immunoassay method in 109 patients with major depressive disorder (MDD)...

There is a lack of information concerning the molecular events underlying the depressive-like effect of an intracerebroventricular injection of streptozotocin (ICV-STZ) in mice. The elevated activity of the tryptophan-degrading enzyme indoleamine-2,3-dioxygenase (IDO) has been proposed to mediate depression in inflammatory disorders. In the present study, we reported that ICV-STZ activates IDO in the hippocampus of mice and culminates in depressive-like behaviors, as measured by the increased duration of immobility in the tail suspension test and decreased sucrose intake in the sucrose preference test...

Appreciable evidence suggests that perturbations within the gut microbiome and the immune system may play a key role in the pathogenesis of depression stemming from earlier stressful experiences. In the present investigation we examined whether microbial changes in cecum contents were associated with social avoidance behaviors, a feature of depression, and pro-inflammatory variations among socially stressed mice. Male C57BL/6 mice experienced social defeat or a control condition once a day for 10 consecutive days...

Erythropoietin (Epo) is a cytokine expressed throughout the body, including in the central nervous system where it can act as a breathing modulator in the central respiratory network. In vitro, Epo allows maintaining the activity of respiratory neurons during acute hypoxia, resulting in inhibition of the hypoxia-induced rhythm depression. In vivo, Epo action on the central respiratory command results in enhancement of the acute hypoxic ventilatory response, allowing a better oxygenation of the body by improvement of gases exchanges in the lungs...

Animal and human studies suggest an association between depression and aberrant immune response. Further, common inflammatory markers may change during the course of antidepressant treatment in patients. The objective of this study was to evaluate changes in inflammatory markers and clinical outcomes from subjects enrolled in the Combining Medications to Enhance Depression Outcome (CO-MED) trial. At baseline and week 12 (treatment completion), plasma samples of 102 participants were analyzed via a multiplex assay comprised of inflammatory markers using a 27-plex standard assay panel plus a 4-plex human acute phase xMAP technology based platform...

Major depression has been interpreted as an inflammatory disease characterized by cell-mediated immune activation, which is generally triggered by various stresses. Microglia has been thought to be the cellular link between inflammation and depression-like behavioural alterations. The expression of cathepsin C (Cat C), a lysosomal proteinase, is predominantly induced in microglia in neuroinflammation. However, little is known about the role of Cat C in pathophysiology of depression. In the present study, Cat C transgenic mice and wild type mice were subjected to an intraperitoneal injection of LPS (0...

BACKGROUND: Indeed, intracerebral hemorrhage (ICH) account for only 15% of all strokes but it is one of the most devastating subtype of stroke associated with behavioral, cognitive and neurological deficits. The primary cause of neurological deficits in ICH is the hematoma growth, generation of free radicals, inflammatory cytokines and exhausting endogenous anti-oxidant machinery. It has been found that neuroinflammation following ICH leads to exaggeration of hallmarks of ICH. With this background, the study was aimed to evaluate the protective effect of resveratrol (RSV) in intracerebroventricular (ICV) collagenase (COL) induced neurological deficits in rats...

Mounting evidence suggests that aberrations in immune-inflammatory pathways contribute to the pathophysiology of major depressive disorder (MDD), and individuals with MDD may have elevated levels of predominantly pro-inflammatory cytokines and C-reactive protein. In addition, previous meta-analyses suggest that antidepressant drug treatment may decrease peripheral levels of interleukin-1 beta (IL-1β) and IL-6. Recently, several new studies examining the effect of antidepressants on these cytokines have been published, and so we performed an updated meta-analysis of studies that measured peripheral levels of cytokines and chemokines during antidepressant treatment in patients with MDD...

Neuroinflammation driven altered neurochemical milieu have been reported to play a significant role in pathogenesis of comorbid depression in epilepsy. Most of the antiepileptic drugs (AEDs) such as levetiracetam, taigabine, topiramate have not been reported any significant effect in alleviating neuroinflammation, which may explain their ineffectiveness in ameliorating depression associated with epilepsy. The supplementation of antidepressants (ADs) attracts various pharmacokinetic and pharmacodynamic interactions with AEDs and was considered unsafe in epilepsy...

Studies suggest that inflammation is involved in the pathophysiology of depression. The present study examined the effects of the commonly used antidepressant escitalopram, in comparison with a novel herbal treatment (NHT) consisted of Crataegus pinnatifida, Triticum aestivum, Lilium brownii and Fructus Ziziphus jujuba, on cytokine and behavioral responses to an immune challenge. Escitalopram augmented lipopolysaccharide-induced tumor necrosis factor (TNF)-α peripheral secretion and induced a faster kinetics of interleukin-1β secretion, while marginally reducing sickness behavior...

OBJECTIVE: Peroxisome proliferator-activated receptor α (PPARα) activation has been reported to ameliorate liver injury in cases of acute liver failure (ALF). However, its intrinsic protective molecular mechanisms remain largely undetermined. C/EBP homologous protein (CHOP) is an important mediator of lipopolysaccharide (LPS)-induced inflammation. The aim of the present study was to test the hypothesis that PPARα activation alleviates liver inflammation to protect mice from acute liver failure (ALF) mediated by CHOP...

Although pain is frequently accompanied with depression, little is known about the risk factors contributing to individual differences to the comorbidity of pain and depression. In this study, we examined whether cytokines and brain-derived neurotrophic factor (BDNF) might contribute to the individual differences in the development of neuropathic pain-induced depression. Rats were randomly subjected to spared nerved ligation (SNI) or sham surgery. The SNI rats were divided into two groups by the data from depression-related behavioral tests...

OBJECTIVES: The objectives of the study were to determine if adjunctive minocycline mitigates depressive symptom severity and improves cognitive function in individuals with bipolar I/II disorder (BD). The study also aimed to determine if changes in depressive and/or cognitive symptoms over the course of treatment were associated with changes in circulating inflammatory cytokine levels. METHODS: A total of 29 (intention-to-treat: n=27) adults meeting DSM-IV-TR criteria for a major depressive episode as part of bipolar I or II disorder (i...

Co-morbid depression is prevalent in patients with obstructive sleep apnea. Here we report that monoamine oxidase A (MAO-A) plays pathogenic roles in the comorbidity. We found that chronic intermittent hypoxia significantly increased the MAO-A expression in the rat hippocampus and markedly decreased the dendritic length and spine density in the pyramidal neurons with less pre- and post-synaptic proteins. The MAO-A upregulation resulted in increased 5-hydroxyindoleacetic acid/serotonin ratio, oxidative stress, leading to NF-κB activation, inflammation and apoptosis...

Obesity and depression are among the most pressing health problems in the contemporary world. Obesity and depression share a bidirectional relationship, whereby each condition increases the risk of the other. By inference, shared pathways may underpin the comorbidity between obesity and depression. Activation of cell-mediated immunity (CMI) is a key factor in the pathophysiology of depression. CMI cytokines, including IFN-γ, TNFα and IL-1β, induce the catabolism of tryptophan (TRY) by stimulating indoleamine 2,3-dioxygenase (IDO) resulting in the synthesis of kynurenine (KYN) and other tryptophan catabolites (TRYCATs)...

Symptoms of depression are present in a significant proportion of Alzheimer's disease (AD) patients. While epidemiological studies have shown a strong association between depression and AD, it has not been established whether depression is a risk factor or merely a co-morbidity of AD. It is also uncertain if depression affects the pathogenesis of AD. In this paper, we address these questions by measuring the serum levels of two common metabolic risk factors of AD and depression, inflammatory cytokines (IL 6 and TNF alpha) and serum 25-hydroxyvitamin D, in a case-control study...

PURPOSE: A growing number of cancer survivors suffer high levels of distress, depression and stress, as well as sleep disturbance, pain and fatigue. Two different mind-body interventions helpful for treating these problems are Mindfulness-Based Cancer Recovery (MBCR) and Tai Chi/Qigong (TCQ). However, while both interventions show efficacy compared to usual care, they have never been evaluated in the same study or directly compared. This study will be the first to incorporate innovative design features including patient choice while evaluating two interventions to treat distressed cancer survivors...
