Project description:BBF2H7 (BBF2 human homolog on chromosome 7), an ER-resident basic leucine zipper transcription factor, is activated in response to ER stress and abundantly expresses in chondrocytes. While BBF2H7 is widely expressed in many tissues and organs, the most intense signals were detected in the proliferating zone of the cartilage. We compared gene expressions in primary cultured chondrocytes prepared from rib cartilage between WT and BBF2H7-/- mice at E18.5. Primary cultured chondrocytes were prepared from E18.5 rib cartilage of WT and BBF2H7-/- mice. Chondrocytes were isolated using 0.2% collagenase D (Roche) after adherent connective tissue was removed by 0.2% trypsin (Sigma) and collagenase pretreatment. Isolated chondrocytes were maintained in α-MEM (Gibco) supplemented with 10% FCS and 50 µg/mL ascorbic acid. Adenovirus vectors expressing the mouse p60 BBF2H7 (1-377 aa, BBF-N) were constructed with the AdenoX Expression system (Clontech), according to the manufacturerâs protocol. The cells were infected with adenoviruses 30 h before analysis. We compared gene expressions in primary cultured chondrocytes prepared from rib cartilage between WT and BBF2H7-/- mice at E18.5 using a microarray and various genes associated with protein secretory pathway and ER biogenesis were significantly down-regulated in BBF2H7-/- chondrocytes. We infected primary cultured chondrocytes prepared from BBF2H7-/- mice with adenovirus expressing p60 BBF2H7. Several genes were up-regulated and we picked up them as the direct target of BBF2H7.

Project description:Transcriptional profiling of mouse chondrocytes comparing chondrocytes infected with empty adenovirus and Epas1 adenovirus. RNA was extracted from each chondrocytes. We used microarrays to determine the effect of Epas1 overexpression on chondrocytes and identify the noble regulatory molecules during osteoarthritic pathogenesis.

Project description:Homeobox genes of the Hox class are required for proper patterning of skeletal elements and play a role in cartilage differentiation. In transgenic mice with overexpression of Hoxc8 during cartilage development, we observed severe defects, namely physical instability of cartilage, accumulation of immature chondrocytes, and decreased maturation to hypertrophy. To define the molecular basis underlying these defects, we performed gene expression profiling using the Affymetrix microarray platform. Embryos were dissected from four different mouse litters at E18.5. Embryos from each litter were grouped according their genotype: TA=control; TR=transgenic.

Project description:We describe how the cancer-causing Epstein-Barr virus (EBV), a prototypic herpesvirus, alters proteome at viral replication forks prominently identifies chromatin modifying and transcriptional repression proteins. Specifically, to transition from transcription, the viral DNA polymerase processivity factor EA-D is SUMOylated by the transcriptional corepressor KAP1-TRIM28. KAP1 function is triggered by phosphorylation via the PI3K-related kinase ATM and the helicase RECQ5 at the transcription machinery. SUMO-EA-D recruits the histone loader CAF1 and the methyltransferase SETDB1 to silence the parental genome, prioritizing replication. Thus, DNA repair, epigenetic, and transcription-replication interference pathways orchestrate the handover from transcription to replication, a fundamental feature of DNA viruses
