Project description:Major depressive disorder (MDD) strikes women twice as often as men, yet the molecular mechanisms contributing to this sex difference are poorly understood. Here, we explored the regulation of long noncoding RNAs (lncRNAs) in human postpartum brain tissue and found a robust baseline sex difference in lncRNA expression levels that is profoundly lost in MDD. We highlight one such lncRNA, that is upregulated in females with MDD, therefore we named FEDORA. FEDORA arose in humans and is expressed primarily in oligodendrocytes as well as in neurons. We tested FEDORA’s causal role in MDD, by utilizing a cell-type-specific approach to express it in the prefrontal cortex (PFC) of mice of both sexes. We found that expressing FEDORA in either neurons or oligodendrocytes promoted depression-like behaviors in females only, which mirrored the human sex-specific phenotype. These behavioral changes were associated with cell-type-specific changes in electrophysiological properties, myelin thickness, and gene expression. Finally, we found that blood FEDORA levels have diagnostic and prognostic features only for women with MDD. Together, these findings suggest that lncRNAs play key roles in shaping the sex-specific landscape of the brain and contribute to sex differences in MDD.

Project description:Long noncoding RNAs (lncRNAs) have appeared to be involved in the most diverse cellular processes through multiple mechanisms. Here we describe a previously uncharacterized human lncRNA, CONCR (cohesion regulator noncoding RNA), transcriptionally activated by MYC, which is upregulated in multiple cancer types. The expression of CONCR is cell cycle-regulated, and it is required for cell cycle progression and DNA replication. Moreover, cells depleted of CONCR show severe defects in sister chromatid cohesion, suggesting an essential role for CONCR in cohesion establishment during cell division. CONCR interacts with and regulates the activity of DDX11, a DNA-dependent ATPase and helicase involved in DNA replication. These findings suggest a novel mechanism of action for CONCR in the modulation of DDX11 enzymatic activity, unveiling the direct involvement of a lncRNA in the establishment of sister chromatid cohesion. Characterization of the function of the long noncoding RNA CONCR. Analysis of DDX11 chromatin binding by ChIP-seq in the presence or absence of CONCR.

Characterization of the function of the long noncoding RNA CONCR. A549 were transfected with a control siRNA or with a combination of two siRNAs targeting CONCR. Three independent siRNA-mediated knockdowns (siRNA CONCR REP1, 2 and 3) and controls (siRNA Control REP1, 2 and 3) were used for the analysis.

Project description:The pleiotropic function of long noncoding RNAs is well recognized, but their direct role in governing metabolic homeostasis is less understood. Here, we describe a human adipocyte-specific lncRNA, ADIPINT, that regulates pyruvate carboxylase , a pivotal enzyme in energy metabolism. With a novel approach, Targeted RNA-protein identification using Orthogonal Organic Phase Separation, and validation with electron microscopy, we show that ADIPINT binds to PC. ADIPINT knockdown alters the interactome and decreases the abundance and enzymatic activty of PC in the mitochondria. Reduced ADIPINT or PC expression lowers adipocyte lipid synthesis, breakdown, and lipid content. In human white adipose tissue, ADIPINT expression is increased in obesity and linked to fat cell size, adipose insulin resistance, and PC activity. Thus, we identify ADIPINT as a regulator of lipid metabolism in human white adipocytes, which at least in part is mediated through its interaction with PC.
