Stressed and Depressed? Check Your GDNF for Epigenetic Repression
نویسنده
چکیده
Some adults fail to adapt to chronic stress, developing symptoms of depression and anxiety. In this issue of Neuron, Uchida and colleagues link maladaptive stress responses to GDNF through a comprehensive investigation of the neurotrophic factor's regulation. Further, this study is an excellent example for investigators interested in neuroepigenetics research.

Impaired Latent Inhibition in GDNF-Deficient Mice Exposed to Chronic Stress
Increased reactivity to stress is maladaptive and linked to abnormal behaviors and psychopathology. Chronic unpredictable stress (CUS) alters catecholaminergic neurotransmission and remodels neuronal circuits involved in learning, attention and decision making. Glial-derived neurotrophic factor (GDNF) is essential for the physiology and survival of dopaminergic neurons in substantia nigra and o...
متن کاملExposure to Early Life Stress Results in Epigenetic Changes in Neurotrophic Factor Gene Expression in a Parkinsonian Rat Model
Early life adversity increases the risk of mental disorders later in life. Chronic early life stress may alter neurotrophic factor gene expression including those for brain derived neurotrophic factor (BDNF) and glial cell derived neurotrophic factor (GDNF) that are important in neuronal growth, survival, and maintenance. Maternal separation was used in this study to model early life stress. Fo...
متن کاملRepression of Astrocytic Connexins in Cortical and Subcortical Brain Regions and Prefrontal Enrichment of H3K9me3 in Depression and Suicide
Background Major depressive disorder has been associated with dysfunctional astrocytic networks. The underlying causes, extent, and consequences of such dysfunctions remain to be characterized. Astrocyte-astrocyte communication occurs principally through gap junction channels primarily formed by connexin 30 and 43 (CX30 and CX43). We previously reported decreased connexin expression in the pref...
متن کاملO-31: Epigenetic Aberration of HOXA10 Gene in Human Endometrium throughout The Menstrual Cycle in Endometriosis
Background: Epigenetic aberration such as DNA methylation and histone modifications appear to be involved in various diseases such as Endometriosis. Here, we investigated the epigenetic regulation of HOXA10 promoter, as a crucial gene, responsible for uterine organogenesis, functional endometrial differentiation and endometrial receptivity, and its correlation with mRNA expression of this gene ...
متن کاملP-88: Comparing Epigenetic Profile of Oct4 Regulatory Region in Embryonal Carcinoma Cells under Retinoic Acid Induction
Background: Embryonal carcinoma (EC) cells derived from germ cell tumors are valuable tools for investigating differentiation and developmental biology processes in vitro. The advantage of the reproducible and rapid expansion of these cell lines provides a useful alternative to embryos for the study of mammalian cell differentiation. During early stages of cell differentiation, the rate of tran...
