Figure 2(A) To verify that disruption of the pst genes is sufficient to increase ampicillin resistance of strains containing the pBR322 bla::Im7 L53A I54A folding biosensor and to test which of the genes in the pst operon are sufficient for this effect, pBR322 and pBR322 bla::Im7 L53A I54A were transformed into strains containing in-frame deletion mutants of each of the pst genes (pstS, pstC, and pstA, respectively). The deletion mutants of each of these pst genes showed higher ampicillin resistance than did the WT strain MG1655 in the presence of pBR322 bla::Im7 L53A I54A, but did not shower higher ampicillin resistance in the presence of pBR322. (B) Levels of β-lactamase (Bla) and β-lactamase-Im7 L53A I54A were detected by Western blotting using a polyclonal antibody recognizing β-lactamase in the WT strain MG1655 and in isogenic strains containing insertions in the pstSCA genes (CL248 (pstS::Tn5), CL249 (pstC::Tn5), CL250 (pstA::Tn5)). Maltose binding protein (MBP) was used as a control. (C) β-lactamase enzymatic activities present in periplasmic extracts of the Im7 folding biosensor were monitored in pst WT and pstSCA mutant strains using a spectrophotometric assay. Data are represented as mean ± SEM from three technical replicates (unpaired t-test,** P<0.01, *** P<0.001 comparison to MG1655; ns, not significant). (D) To test if levels of the Im7 L53A I54A protein itself, in the absence of the fusion, were also higher in the pstA mutant, expression of the Im7 L53A I54A protein from the IPTG-inducible plasmid pCDFTrc was induced using IPTG concentrations ranging from 0-5 mM. Periplasmic fractions were isolated and examined by SDS-PAGE and subsequent Coomassie staining to determine overall protein expression patterns. Im7 L53A I54A levels were determined by Western blotting using an antibody for Im7. MBP was used as a loading control. Im7 L53A I54A was increased in the pstA strain relative to the WT control strain. Coomassie staining revealed that a number of periplasmic proteins, including UgpB, were also induced in the pstA strain.

Long-term restoration of COLVII expression, generation of epidermis and anchoring fibrils by the progeny of a corrected recessive dystrophic epidermolysis bullosa (RDEB) epidermal stem cell.Figure 4Serial cultivation of transduced and untransduced holoclones demonstrated that the growth potential of the stem cells was not affected by the production of COLVII. Non-COLVII-producing holoclone 54 (black lines) and COLVII-producing holoclone 6 (red lines) were serially transferred once a week until exhaustion (Rochat et al, 1994).Theoretical number of epidermal cells available for characterisation and CEA production from corrected (clone 6) and uncorrected stem cells (clone 54) calculated from the day of cloning. The colony-forming efficiency and the percentage of growing colonies for each passage were used to calculate the population doubling, the generation number and the total progeny of isolated stem cells. Both corrected and uncorrected epidermal stem cells show high growth potential in vitro. Immunodeficient SCID mice were transplanted with untransduced cultured RDEB keratinocytes (left) or the COLVII-secreting holoclone (clone 6) (right). Punch biopsies were obtained at various times post-transplantation (PT), stained with haematoxylin/eosine (H/E), for human leucocyte antigen-1 (HLA-1) (green) and human COLVII (red). RDEB keratinocytes generated a HLA-1-positive epidermis that adhered poorly to the dermo-epidermal junction (DEJ) (arrow indicates a blister) and absence of COLVII (dotted line delimits the dermis), whereas the corrected keratinocytes produced an epidermis that adhered to the dermis and deposited COLVII (red) at the DEJ. Note the presence of KI67-positive keratinocytes (red) in the basal and suprabasal layers in the corrected epidermis at 385 days post-transplantation, indicating that transplanted cells had self-renewed for more than a year. Scale bar: 50 μm. Transmission electron microscopy (TEM) demonstrated the presence of anchoring fibrils (arrows) at the DEJ of the corrected epidermis (middle right panel) and in a normal human skin biopsy (left panel). Note the absence of anchoring fibrils in the RDEB epidermis (middle left panel). Detection of human COLVII by immunogold staining in the DEJ of corrected epidermis (right panel). Scale bar: 250 nm.

Figure 7A. Mitochondrial localization of a Tom20-LarpGFP (Tom20-Larp) fusion protein in an mdi1 egg chamber stained with ATP-S to reveal mitochondria. Bars, 20 m. B. Hatching rates and mtDNA contents of eggs produced by flies with different genotypes relative to wt control; each data point represents the mean of 3 independent replicates. Bars, std. Expression of Tom20-Larp in mdi1 (mdi1;Tom20-Larp) significantly restored the mtDNA level and hatching rate. N= 3 x >100 eggs / genotype for hatching rate. The relative mtDNA level was the average of 3 biological repeats. P values of comparing mdi1;Tom20-Larp to mdi1: for mtDNA level, P=0.0209; for hatching rate, P=3.4758E-05. C. Model of the role of MDI and Larp in mitochondrial biogenesis. MDI (green rectangle) localizes at the mitochondrial outer membrane, and recruits Larp (blue rectangle) to the mitochondrial surface. Larp interacts with polysome (blobs) and translation stimulators, and stimulate the translation of a subset of nuclear-encoded mRNAs. Proteins synthesized on the mitochondrial surface are in close vicinity of the Tom-Tim mitochondrial transporter complexes, which would facilitate their rapid transport into the matrix. The targets of MDI-Larp complexes include most nuclear-encoded ETC subunits, mitochondrial ribosomal proteins, TFAM, and mtDNA polymerase (Tamas) (collectively represented in red). Mitochondrial ribosomes are required for the biogenesis of proteins encoded by mtDNA, all of which are ETC subunits. Thus MDI-Larp complexes seem to coordinate the expression of both nuclear and mitochondrial genome to promote the biogenesis of ETC complexes.
