The Identification of Potential Anti-Depression/Anxiety Drug Targets by Stress-Induced Rat Brain Regional Proteome and Network Analyses.

Depression and anxiety disorders are prevalent stress-related neuropsychiatric disorders and involve multiple molecular changes and dysfunctions across various brain regions. However, the specific and shared pathophysiological mechanisms occurring in these regions remain unclear. Previous research used a rat model of chronic mild stress (CMS) to segregate and identify depression-susceptible, anxiety-susceptible, and insusceptible groups; then the proteomes of six distinct brain regions (the hippocampus, prefrontal cortex, hypothalamus, pituitary, olfactory bulb, and striatum) were separately and quantitatively analyzed.

IRTKS contributes to the malignant progression of cervical cancer cells.

Cervical cancer (CC), one of the most aggressive tumors in women, has high risk rates of recurrence and metastasis. It is essential to study the key genes and proteins involved in CC development. IRTKS, a member of the IRSp53 family, has been reported as a tumor promoter in gastric and breast cancers.

Effects of Camk2b Overexpression and Underexpression on the Proteome of Rat Hippocampal Neurons.

Recent studies have demonstrated that Camk2b expression is modified in neuropsychiatric illnesses and potentially affects synaptic plasticity. However, the molecular events arising from Camk2b dysregulation are not fully elucidated and need to be comprehensively explored. In the present study, we first induced over-expression and under-expression of Camk2b in cultured rat hippocampal neurons through transfection with lentivirus plasmids.

Influence of Dichloroacetate on Wilms'Tumor .

Objective: To investigate the effect of dichloroacetate (DCA) on Wilms' tumor (WT) G401 cells.

Proteomic Insights Into Susceptibility and Resistance to Chronic-Stress-Induced Depression or Anxiety in the Rat Striatum.

Chronic stress is a key factor for the onset of anxiety and depression disorders. However, the stress-induced common and unique molecular basis of the two psychiatric disorders is not fully known and still needs to be explored. Previously, we employed a chronic mild stress (CMS) procedure to induce a rat model including depression-susceptible (Dep-Sus), anxiety-susceptible (Anx-Sus), and insusceptible (Insus) cohorts.

Proteomic Response of Rat Pituitary Under Chronic Mild Stress Reveals Insights Into Vulnerability and Resistance to Anxiety or Depression.

Chronic stress as one of the most significant risk factor can trigger overactivity of hypothalamic-pituitary-adrenal (HPA) axis in depression as well as anxiety. Yet, the shared and unique neurobiological underpinnings underlying the pituitary abnormality in these two disorders have not been made clear. We previously have established depression-susceptible, anxiety-susceptible and insusceptible groups using a valid chronic mild stress (CMS) model.

Comparative Proteomics of Rat Olfactory Bulb Reveal Insights into Susceptibility and Resiliency to Chronic-stress-induced Depression or Anxiety.

Chronic stress causes the abnormality of olfactory bulb (OB) in both anxiety and depression, however, the unique and common neurobiological underpinnings are still poorly understood. Previously, we built the three groups by chronic mild stress (CMS), depression-susceptible (Dep-Sus): with depression-like behavior, anxiety-susceptible (Anx-Sus): with anxiety-like behavior and insusceptible (Insus): without depression- and anxiety-like behaviors. To continuously explore the protein expression changes in these three groups, comparative quantitative proteomics analysis was conducted on the rat OB as crucial part of the olfactory system.

Global effects of RAB3GAP1 dysexpression on the proteome of mouse cortical neurons.

Mounting studies have demonstrated that RAB3GAP1 expression is modified in brain diseases with multiple neurobiological functions and processes and acts as a potentially significant target. However, the cellular and molecular events arising from RAB3GAP1 dysexpression are still incompletely understood. In this work, underexpression and overexpression of RAB3GAP1 were first induced into cultured mouse cortical neurons by transfection with lentivirus plasmids.

Analysis of Chronic Mild Stress-Induced Hypothalamic Proteome: Identification of Protein Dysregulations Associated With Vulnerability and Resiliency to Depression or Anxiety.

Chronic stress as a known risk factor leads to hyperactivity of the hypothalamus-pituitary-adrenal (HPA) axis in both depression and anxiety. However, the stress-induced dysfunction of the HPA axis in these disorders especially the common and unique molecular dysregulations have not been well-explored. Previously, we utilized a chronic mild stress (CMS) paradigm to segregate and gain depression-susceptible, anxiety-susceptible, and insusceptible groups.

Chronic mild stress-induced protein dysregulations correlated with susceptibility and resiliency to depression or anxiety revealed by quantitative proteomics of the rat prefrontal cortex.

Chronic stress is a significant risk factor for depression as well as anxiety disorders. Yet, the stress-induced specific and common molecular dysregulations of these disorders have not been fully understood. Previously, we constructed a chronic mild stress (CMS) rat model to separate and obtain depression-susceptible, anxiety-susceptible, and insusceptible groups.

Down-regulation of PDGFRβ suppresses invasion and migration in osteosarcoma cells by influencing epithelial-mesenchymal transition.

Osteosarcoma (OS) is the most common malignant bone tumor primarily influencing children and adults. Approximately one-fifth of patients have micrometastasis in the lungs when OS is diagnosed. Platelet-derived growth factor receptor (PDGFR) beta (PDGFRβ) is a subtype of PDGFR.

[Inhibiting the expression of glucose transporter 1 reduces the proliferation, invasion and migration of neuroblastoma cells].

Objective To study the effect of inhibiting the expression of glucose transporter 1 (GLUT1) in neuroblastoma cells on the proliferation, invasion and migration of tumor cells.
