Description
Mechanisms controlling the proliferative activity of neural stem/progenitor cells (NSPCs) play a pivotal role to ensure life-long neurogenesis in the mammalian brain. How metabolic programs are coupled with NSPC activity remains unknown. Here we show that fatty acid synthase (FASN), the key enzyme of de novo lipogenesis, is highly active in adult NSPCs and that conditional deletion of FASN in NSPCs impairs adult neurogenesis. The rate of de novo lipid synthesis and subsequent proliferation of NSPCs is regulated by Spot14, a gene we found to be selectively expressed in low proliferating adult NSPCs. Spot14 reduces the availability of malonyl-CoA, which is an essential substrate for FASN to fuel lipogenesis. Thus, we here identified a functional coupling between the regulation of lipid metabolism and adult NSPC proliferation.

Description
Multiple Myeloma (MM) is a plasma cell tumor localized to the bone marrow (BM). Despite current progress in improving patient outcome, MM remains largely incurable. Disease clonal and interpatient heterogeneity has hampered identification of a common underlying mechanism for disease establishment and have slowed the development of novel targeted therapies. Epigenetic aberrations are now emerging as increasingly important in tumorigenesis, thus selective targeting of crucial epigenetic enzymes may provide new therapeutic potential in cancer including MM. Recently, we and others suggested the histone methyltransferase enhancer of zeste homolog 2 (EZH2), to be a potential therapeutic target in MM. Now we show that pharmacological inhibition of EZH2 suppresses the MM cell growth through downregulation of MM-associated oncogenes; IRF-4, XBP-1, PRDM1/BLIMP-1and c-MYC. We also show that downregulation of these genes is mediated via reactivated expression of microRNAs with tumor suppressor functions; primarily miR125a-3p and miR320c. Using chromatin immunoprecipitation (ChIP) we demonstrate that miR125a-3p and miR320c are targets of EZH2 and H3K27me3 in MM cell lines and primary MM cells. Our results further highlight the importance of polycomb-mediated silencing in MM to include microRNAs with tumor suppressor activity. This novel role further strengthens the oncogenic features of EZH2 and its potential as a therapeutic target in MM.

Description
Interrogation and control of cellular fate and function using optogenetics is providing revolutionary insights into biology. Optogenetic control of cells is achieved by coupling genetically encoded photoreceptors to cellular effectors and enables unprecedented spatiotemporal control of signaling processes. Here, a fast and reversibly switchable photoreceptor is used to tune the mechanical properties of polymer materials in a fully reversible, wavelength-specific, and dose- and space-controlled manner. By integrating engineered cyanobacterial phytochrome 1 into a polyethylene glycol matrix, hydrogel materials responsive to light in the cell-compatible red/far-red spectrum are synthesized. These materials are applied to study in human mesenchymal stem cells how different mechano-signaling pathways respond to changing mechanical environments, and to control the migration of primary immune cells in 3D. This optogenetics-inspired matrix allows addressing fundamental questions of how cells react to dynamic mechanical environments. Further, remote control of such matrices could create new opportunities for tissue engineering or provide a basis for optically stimulated drug depots.
