Definitions
- the present invention relates to a composition for preventing, improving or treating mitochondrial complex 1 abnormality disease, comprising a recombinant adeno-associated virus vector loaded with Hydra NDi1.
- Mitochondrial genetic diseases caused by mutations in the mitochondrial genome were first reported about 30 years ago, and since then, there has been a rapid advance in understanding numerous diseases caused by mutations in the mitochondrial genome and mitochondrial genetics involved in the transmission of the mitochondrial genome.
- the severity of the disease symptoms varies depending on the ratio of the mutated genome, and the higher the ratio of the mutated genome, the more severe the symptoms.
- the heteroplasmy of the mitochondrial genome mutations induced in the same way varies greatly depending on the tissue of the human body or the individual, and much research is still needed to elucidate the mechanism that controls heteroplasmy.
- LHON Leber's hereditary optic neuropathy
- mtDNA mitochondrial DNA
- Mitochondria are important intracellular bodies that produce energy (ATP) used for biological activities, and unlike nuclear genes, they have independent genes. Most genetic diseases are caused by defects in the genes in the nucleus, but some can be caused by abnormalities in the mitochondrial genes. A pair of genes in the nucleus are inherited from each parent, but mitochondrial genes are inherited only from the mother because the mitochondrial genes, including the paternal genes, are separated from the sperm tail during fertilization and cannot enter the egg. LHON accounts for 30-50% of unexplained optic neuropathy that occurs in both eyes and 2% of legal blindness.
- vitamin C, vitamin B12 , or idebenone may alleviate damage to retinal ganglion cells in patients with the disease, but the effect is minimal, so it is not widely used in clinical practice, and it has the limitation of not being able to fundamentally prevent the disease. Therefore, there is currently no proper treatment, and gene therapy is the only fundamental treatment.
- the inventors of the present invention constructed a recombinant viral vector containing hydra NDi1 to effectively treat mitochondrial abnormalities, and experimentally demonstrated that the vector can be used to prevent, improve, and treat mitochondrial abnormalities, thereby completing the present invention.

- AAV Adeno-associated virus
- pHelper vector the first vector
- pRC vector the subtype
- ssAAV single-stranded AAV
- scAAV self-complementary AAV
- GOI gene of interest
- pAAV-DJ was used as the pRC vector, and the genes of interest were GFP (Green fluorescent protein), IRES (internal ribosome entry site)-GFP, yeast NDi1 (GenBank: X61590.1), and hydra NDi1 (NCBI Reference Sequence: XM_002156815.3). Individual maps of the vectors used in the experiment are shown in Figures 1 and 2.
- All of the vectors for the above AAV production were purchased from Cell Biolabs (San Diego, CA), and AAV-293 (Agilent, Santa Clara, CA) was used for 293 cells. After culturing 293 cells in a 150 mm dish to about 90% confluence, the first vector, the second vector, and the third vector were well mixed at a ratio of 20 ug, 10 ug, and 10 ug, respectively, and then mixed with CaCl2 solution and evenly spread on the 293 cells. After 3 days, the 293 cells were scraped with a cell scraper, purified with an AAVpro Purificatin Kit (Takara, San Jose CA), and the titer was measured with the company's AAVpro Titration Kit. They were then stored at -80°C until use.
- scAAV-GFP and ssAAV-GFP were infected into fibroblasts, and the degree of green fluorescence expression was confirmed.
- the experiment was conducted using the recombinant AAV shown in Fig. 3a. Specifically, skin fibroblast cells derived from LHON patients were cultured in a 12-well plate to about 70% confluence, and then about 10 9 viral genomes (vg) of ssAAV-2/DJ-GFP or scAAV-2/DJ-GFP were added per well to infect the cells. After 3 days, the degree of GFP expression by each recombinant AAV in the infected cells was observed under an FITC filter with an inverted fluorescence microscope. The results are shown in Fig. 3b.
- scAAV-GFP expresses green fluorescence more strongly within cells than ssAAV-GFP. This means that scAAV stably expresses genes (stability) and has high gene expression intensity.
- a 24-well plate dedicated to measuring cellular respiration skin fibroblasts derived from LHON patients were cultured to about 50% confluence and then infected with ssAAV-IRES-GFP, ssAAV-yeast NDi1, ssAAV-hydra NDi1, and scAAV-hydra NDi1 at a titer of about 10 8 vg per well, respectively.
- OCR oxygen consumption rate
- rotenone was added to the cells to confirm the inhibitory effect on the decrease in cellular respiration by yeast NDi1 and hydra NDi1.
- Cellular respiration was confirmed by measuring the oxygen consumption rate (OCR) using Agilent's Seahorse XF-24. The results are shown in Fig. 4.
- scAAV-hydra NDi1 inhibited the reduction of cellular respiration induced by rotenone more efficiently than ssAAV-yeast NDi1.
- LHON patient dermal fibroblasts were cultured to about 70% confluence in 24-well plates and then infected with ssAAV-IRES-GFP, ssAAV-yeast NDi1, ssAAV-hydra NDi1, and scAAV-hydra NDi1 at a titer of about 10 9 vg per well, respectively.
- Rotenone was treated 6 days later, and cell death was observed 1 day after rotenone treatment. The results are shown in Figs. 5a to 5d. Cell death was determined comprehensively by considering the shape and form of individual cells, the degree of attachment to the bottom, and the strength of contact with adjacent cells.
- ssAAV-IRES-GFP 3 days after rotenone treatment, untransduced cells or cells infected with ssAAV-IRES-GFP were completely killed at 5 nM rotenone, and cells infected with ssAAV-yeast NDi1 or ssAAV-hydra NDi1 began to die significantly even at 10 nM rotenone. In contrast, cells infected with scAAV-hydra NDi1 under the same conditions were hardly killed even at 20 nM rotenone.
- cells infected with ssAAV-yeast NDi1 or ssAAV-hydra NDi1 also showed some death at 5 nM rotenone and almost no death at 10 nM.
- cells infected with scAAV-hydra NDi1 showed almost no death even at 20 nM.
- scAAV-hydra NDi1 is significantly more effective in inhibiting apoptosis of LHON patient-derived cells mediated by mitochondrial complex 1 or higher than ssAAV-hydra NDi1 and ssAAV-yeast NDi1.
- the scAAV-hydra NDi1 of the present invention has an effect of restoring the decrease in cellular respiration caused by rotenone and an effect of inhibiting the death of cells derived from LHON patients caused by rotenone. Therefore, it is expected that this can be used for the prevention, improvement, or treatment of diseases caused by abnormalities in mitochondrial complex 1 as well as LHON.
