Normal skeletal development requires tight coordination of transcriptional networks, signaling pathways, and biomechanical cues, and many of these pathways are dysregulated in pathological conditions affecting cartilage and bone. Recently, a significant role has been identified for long noncoding RNAs (lncRNAs) in developing and maintaining cellular(More)
Regions of transcription initiation and termination in kinetoplastid protists lack known eukaryotic promoter and terminator elements, although epigenetic marks such as histone variants and the modified DNA base J have been localized to these regions in Trypanosoma brucei, Trypanosoma cruzi, and/or Leishmania major. Phenotypes of base J mutants vary(More)
The genomes of kinetoplastids are organized into polycistronic gene clusters that are flanked by the modified DNA base J. Previous work has established a role of base J in promoting RNA polymerase II termination in Leishmania spp. where the loss of J leads to termination defects and transcription into adjacent gene clusters. It remains unclear whether these(More)
MicroRNAs (miRNAs) can regulate cellular differentiation processes by modulating multiple pathways simultaneously. Previous studies to analyze in vivo miRNA expression patterns in developing human limb cartilage tissue identified significant downregulation of miR-483 in hypertrophic chondrocytes relative to proliferating and differentiated chondrocytes.
