| 1 | Inhibition of Cdk5 increases osteoblast differentiation and bone mass and improves fracture healing显示文摘Identification of regulators of osteoblastogenesis that can be pharmacologically targeted is a major goal in combating osteoporosis,a common disease of the elderly population. Here, unbiased kinome RNAi screening in primary murine osteoblasts identified cyclin-dependent kinase 5(Cdk5) as a suppressor of osteoblast differentiation in both murine and human preosteoblastic cells. Cdk5 knockdown by si RNA, genetic deletion using the Cre-lox P system, or inhibition with the small molecule roscovitine enhanced osteoblastogenesis in vitro. Roscovitine treatment significantly enhanced bone mass by increasing osteoblastogenesis and improved fracture healing in mice. Mechanistically, downregulation of Cdk5 expression increased Erk phosphorylation, resulting in enhanced osteoblast-specific gene expression. Notably, simultaneous Cdk5 and Erk depletion abrogated the osteoblastogenesis conferred by Cdk5 depletion alone, suggesting that Cdk5 regulates osteoblast differentiation through MAPK pathway modulation. We conclude that Cdk5 is a potential therapeutic target to treat osteoporosis and improve fracture healing. | Mubashir Ahmad Benjamin Thilo Krüger Torsten Kroll Sabine Vettorazzi Ann-Kristin Dorn Florian Mengele Sooyeon Lee Sayantan Nandi Dilay Yilmaz Miriam Stolz Naveen Kumar Tangudu David Carro Vázquez Johanna Pachmayr Ion Cristian Cirstea Maja Vujic Spasic Aspasia Ploubidou Anita Ignatius Jan Tuckermann | 2022 | Bone Research2022，10，3： | 2 |

| 3 | Systematic Characterization of Cell Cycle Phase-dependent Protein Dynamics and Pathway Activities by High-content Microscopy-assisted Cell Cycle Phenotyping显示文摘Cell cycle progression is coordinated with metabolism, signaling and other complex cellular functions. The investigation of cellular processes in a cell cycle stage-dependent manner is often the subject of modern molecular and cell biological research. Cell cycle synchronization and immunostaining of cell cycle markers facilitate such analysis, but are limited in use due to unphysiological experimental stress, cell type dependence and often low flexibility. Here, we describe high-content microscopy-assisted cell cycle phenotyping(hi MAC), which integrates high-resolution cell cycle profiling of asynchronous cell populations with immunofluorescence microscopy. hi MAC is compatible with cell types from any species and allows for statistically powerful, unbiased, simultaneous analysis of protein interactions, modifications and subcellular localization at all cell cycle stages within a single sample. For illustration, we provide a hi MAC analysis pipeline tailored to study DNA damage response and genomic instability using a 3–4-day protocol,which can be adjusted to any other cell cycle stage-dependent analysis. | Christopher Bruhn Torsten Kroll Zhao-Qi Wang | 2014 | Genomics, Proteomics & Bioinformatics2014，12，6： | 0 |
