Context: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Dysregulated expression of miR-146b and androgen receptor (AR) has been shown to play critical roles in tumorigenesis in PTC. However, the mechanistic and clinical association between AR and miR-146b is not fully understood.
View Article and Find Full Text PDFActivated toll-like receptor (TLR) signaling has been well investigated in major depressive disorder (MDD). We previously reported that TNFAIP3, TLR4, TNIP2, miR-146a, and miR-155 play important roles in regulating the toll-like receptor 4 (TLR4) signaling pathway and may serve as novel targets in the pathogenesis of MDD. Recently, aberrant histone modification has been implicated in several psychiatric disorders, including schizophrenia and mood disorder; the most thoroughly studied modification is histone 3 lysine 4 tri-methylation (H3K4me3).

However, the role of estrogen receptors (ERs) in the pathogenesis of PTC remains unclear. The present study aimed to determine the association of ER mRNA expression levels with clinicopathologic features in PTC.

However, that the distribution of these microRNAs in exosomes could be a biomarker of central nervous system diseases is just beginning to be explored. In the present study, we isolated serum exosomes from patients with MDD and healthy controls to explore the levels of exosomal microRNAs, including let-7e, miR-21-5p, miR-223, miR-145, miR-146a, and miR-155.

Aberrant expression of GR has been associated with inflammation in patients with major depressive disorder (MDD). Our previous studies showed that the aberrant expression of TNFAIP3 gene, which encodes the NF-κB regulatory protein A20, TNFAIP3-associated proteins and Toll-like receptors (TLRs) are involved in inflammation-associated depression.

We established a skeletal muscle ischemic injury model by injection of a myotoxin bupivacaine (BPVC) into gastrocnemius muscle of C57BL/6 mice. Throughout the angiogenic and fibrotic phases of muscle healing, was considerably downregulated in BPVC-injured gastrocnemius muscle.

Here we found loss of AR accelerated development of depressive-like behaviors in mice under chronic mild stress (CMS). Mechanism dissection indicated that AR might function via altering the expression of miR-204-5p to modulate the brain-derived neurotrophic factor (BDNF) expression to influence the depressive-like behaviors in the mice under the CMS.

Objective: Elevated levels of pro-inflammatory cytokines, in particular tumor necrotic factor alpha (TNF-α), and abnormalities in negative regulation in Toll-like receptor (TLR) signaling pathways are associated with major depressive disorder (MDD). Previous research by our group disclosed lower expression of TNF-α-induced protein 3 (TNFAIP3), one of the negative regulators of the TLR4 signaling pathway, in depressive patients than in healthy controls.
Methods: In this study, we assessed the mRNA levels of TNFAIP3, TNFAIP3-interacting proteins (TNIP), including TNIP1, TNIP2, and TNIP3, and TNFAIP3-like proteins, such as cezanne1, cezanne2, trabid, and VCIP135, in TNF-α-secreting cells and examined their association with severity of depression using the 17-item Hamilton Depression Rating Scale (HAMD-17) scores from 30 MDD patients and 30 healthy controls.
Chronic inflammation and abnormalities in Toll-like receptor (TLR) signaling pathways are associated with major depressive disorder (MDD). Our previous work reported that impaired negative regulators for the TLR pathways are associated with MDD. This study aimed to assess the association between the severity of depression and the intracellular microRNAs that regulate TLR4 signaling in both peripheral blood mononuclear cells (PBMCs) and monocytes from MDD patients.

Objective: Changes in the brain's inflammatory status can lead to psychopathological responses, especially depression. Using animal models, recent studies have revealed that this pathology is due, in part, to innate immune responses of monocytes.
Methods: We focus on the involvement of Toll-like receptors (TLRs) and expression of genes encoding their negative regulators, SOCS1, TOLLIP, SIGIRR, MyD88s, NOD2, and TNFAIP3, in CD14+ monocytes from 34 patients with major depressive disorder (MDD) and 33 healthy controls before and after treatment with antidepressants.

Background: Major depressive disorder has been shown to be associated with inflammation and the dysregulation of innate immune responses. Previously, we showed an inverse correlation between the severity of depression and level of TNFAIP3 mRNA expression. The present study further evaluated the association between TNFAIP3 mRNA expression level and symptoms of major depressive disorder (MDD) in 91 patients (20 men and 71 women).

Anti-NMDAR antibody in neuropsychiatric patients who had catatonia before were investigated in a follow-up evaluation. The intensity of antibody immunofluorescence was quantified and compared with healthy controls.

This study aims to investigate the efficacy of lorazepam-diazepam protocol in catatonia due to general medical conditions (GMC) and substance.
Method: Patients with catatonia that required psychiatric intervention in various settings of a medical center were included.
Inflammation and abnormalities in Toll-like receptor (TLR) expression and activation have been linked to major depressive disorder (MDD). However, negative regulators of TLR pathways have not been previously investigated in this context. Here, we sought to investigate the association of depression severity, measured by the 17-item Hamilton Depression Rating Scale (HAMD-17), with mRNA expression levels of negative regulators of the TLR pathway, including SOCS1, TOLLIP, SIGIRR, MyD88s, NOD2 and TNFAIP3, in peripheral blood mononuclear cells (PBMCs) from 100 patients with MDD and 53 healthy controls, before and after treatment with antidepressants.

However, catatonia may reemerge after some time, but there are few data on the relapses and recurrences of catatonia. We aimed to investigate the characteristics of patients with relapses or recurrences of catatonia as well as the efficacy of the lorazepam-diazepam protocol on them.

Background: In our previous study, toll-like receptor 4 (TLR4) mRNA expression level was associated with severity of major depressive disorder (MDD) evaluated with the 17-item Hamilton Depression Rating Scale (HAMD-17). However, there are few studies that have investigated the relationship between symptoms of MDD and changes in TLR4 expression. Therefore, the aim of the present study was to further analyze the association between subscales of HAMD-17 and TLR4.

TLR4 was thought to be associated with major depressive disorder in animal model, but the others were still unknown. In order to examine TLR1-9 mRNA expression levels in peripheral blood and their relationships with the psychopathology of major depressive disorder, 30 patients with major depressive disorder were compared with 29 healthy controls.

In this study, we tried to investigate the protein levels of BDNF and TrkB from peripheral blood in the veins of individuals with schizophrenia and health controls.
Methods: From January 2008 to November 2010, we recruited 40 schizophrenic patients and 56 healthy controls.
Background: Catatonia has risks of severe morbidity and mortality and needs early treatment. In this study, we investigated more patients to discuss the efficacy of this treatment in patients with major depressive disorder (MDD) or bipolar I disorder (BPI).
Methods: During a period of 9 years, we identified 12 catatonic patients with mood disorder, with MDD (n = 10) and BPI (n = 2) in the emergency department, inpatient and outpatient units of a general hospital.
Aim: In this study, we investigated serum protein levels of brain-derived neurotrophic factor (BDNF) and its receptor tropomyosin-related kinase B (TrkB) in patients with bipolar disorder.
Methods: Over a 2-year period, 26 patients with bipolar I disorder (manic episode) and 56 healthy controls were recruited. The Young Mania Rating Scale scores of patients with bipolar mania were >26.

Accumulating evidence suggests that the brain-derived neurotrophic factor (BDNF) and its receptor tropomyosin-related kinase B (TrkB) are molecules involved in the pathophysiology of major depressive disorder and response of antidepressants. To examine both BDNF and TrkB protein levels and their relationship with psychopathology in patients with major depressive disorder, 55 physically healthy patients with major depressive disorder were compared with 53 healthy controls. The severity of major depression was assessed by the 17-item Hamilton Depression Rating Scale (HDRS).
