![]() ![]() Overall, our study is unique in that we identified miRNAs differentially expressed during early, mid, and late osteoclastogenesis in a population of primary mouse bone marrow cells enriched for osteoclast progenitors. This suggests that many miRNA clusters differentially expressed during osteoclastogenesis converge on some key functional pathways. Computational analyses predicted mTOR, PI3 kinase/AKT, cell-matrix interactions, actin cytoskeleton organization, focal adhesion, and axon guidance pathways to be top targets of several miRNA clusters. In contrast, overexpression of miR-451 had no effect. Inhibition of miR-365 increased osteoclast number but decreased osteoclast size, while miR-99b inhibition decreased both osteoclast number and size. We validated the function and expression of miR-365, miR-451, and miR-99b, which were found in distinct clusters. Expression of 93 miRNAs, changed by >2 fold during early, mid, and late stages of osteoclastogenesis, were identified and sorted into 7 clusters. An Agilent microarray platform was used to analyze expression of mature miRNAs in an enriched population of murine bone marrow osteoclast precursors (depleted of B220 + and CD3 + cells) undergoing 1, 3, or 5 days of RANKL-driven differentiation. However, a more complete miRNA signature, encompassing early, mid and late stages of osteoclastogenesis, is wanting. Prior studies profiled miRNA expression in murine osteoclast precursors treated with RANKL for 24 hours. Disruption of miRNA-mediated regulation alters osteoclast formation and bone resorption. microRNAs (miRNAs) are key post-transcriptional regulators that repress expression of target mRNAs controlling osteoclast proliferation, differentiation, and apoptosis. This stringent regulation is crucial to prevent excessive or insufficient bone resorption and to maintain bone homeostasis. Osteoclast formation and function are tightly regulated by transcriptional, post-transcriptional and post-translational mechanisms. ![]() In general, students have had difficulty completing GIS assignments in UConn AnyWare, so I highly recommend installing the software on your local machine if at all possible.ĪrcGIS Desktop 10.8.x (and newer): Run the Check for ArcGIS Desktop Updates utility from the Start > All Programs > ArcGIS menu.ĪrcGIS Desktop 10.7.x (and older): Patches and Service Packs for ESRI products can be found at HERE.ĪrcGIS Pro: You can update your ArcPro software in the program Settings.Ĭontact Rich Mrozinski for more information.To design novel therapeutics against bone loss, understanding the molecular mechanisms regulating osteoclastogenesis is critical. If you do have a Mac, another option is to use ArcGIS on UConn AnyWare. ![]() It will not run in the MacOS, unless you are running some sort of Windows virtualization software (something like VirtualBox or VMWare Fusion or Parallels). So, contact Rich Mrozinski ( if you have problems. – Do not contact ESRI for software support. There are several things you should know before using this software. Instructions for downloading from the AGOL portal are here. I recommend moving all GIS projects to use ArcGIS Pro as soon as possible.ĪrcGIS Pro can be downloaded on the ArcGIS Online (AGOL) site. ArcMap) as the software has reached the end of life and is being phased out by ESRI. UConn students have the opportunity to install ArcGIS Pro on their personal computer.ĪrcGIS Desktop – UConn does not have the licensing for student copies of ArcGIS Desktop (i.e. ![]()
