Biomarker platform for parkinson's disease using patient-derived primary dermal fibroblasts
Primary skin fibroblasts obtained from individuals diagnosed with late-onset sporadic Parkinson's disease (PD), were compared to healthy age-matched controls. Fibroblasts from PD subjects had higher growth rates, and appeared distinctly different in terms of morphology and spatial organization in culture, compared to control cells. The PD fibroblasts also exhibited significantly compromised mitochondrial structure and function when assessed via morphological and oxidative phosphorylation assays. Additionally, an increase in baseline macroautophagy levels was seen in cells from PD subjects. Exposure of the skin fibroblasts to physiologically relevant stress, specifically ultraviolet irradiation (UVA), further exaggerated the autophagic dysfunction in the PD cells. Moreover, the PD fibroblasts accumulated higher levels of reactive oxygen species (ROS) coupled with lower cell viability upon UVA treatment. These results highlight primary skin fibroblasts as a patient-relevant model that captures fundamental PD molecular mechanisms, and enable their utility as diagnostic and prognostic biomarkers for PD. |

Expression from transposon-based vectors and uses
Recombinant expression vectors are disclosed that include a control sequence for recombinant expression of proteins of interest; the control sequence combines a mCMV enhancer sequence with a rat EF-1alpha intron sequence. Some of the vectors are useful for tetracycline-inducible expression. Some of the vectors contain a 5′ PiggyBac ITR and a 3′ PiggyBac ITR to promote genomic integration into a host cell chromosome. A method of selecting a stable production cell line for manufacturing a protein of interest is also disclosed. Also disclosed are mammalian host cells comprising the inventive recombinant expression vectors and a method of producing a protein of interest, in vitro, involving the mammalian host cell. |
