Abstract:
Genomic Replacement Therapy uses the human genome found in mantle dentin of a patient&#39;s tooth to affect other cells of the body. Mantle Dentin cells in the developed tooth do not reproduce, therefore the DNA is “younger”. Replacing the genome with a “younger” one will hopefully create beneficial effect to the recipient cells.

       BACKGROUND OF THE INVENTION  
       [0004]     This invention lies in the field of medical or biological science. The range of the application will include cosmetic and medical functions. The cosmetic applications will include a treatment for hair loss, hair discoloration related to aging, and a restoration of proteins such as collagen and elastin. The medical applications will include a treatment for cancer and a beneficial application for nerve damage. The procedure is similar to both mammalian cloning and to gene replacement therapy.  
         [0005]     In mammalian cloning, an egg with the original genetic material removed is injected with genetic material from another mammal. This was performed by Dr. Ian Wilmut&#39;s team and resulted in the first cloned mammal, “Dolly” the sheep. The techniques here include the removal of a full genome and placing it in an egg. In gene replacement therapy, a damaged or harmful gene is replaced with a copy created in the laboratory. If the gene is accepted into the cell, then the phenotypic result should become evident as the patient&#39;s cells express themselves and/or reproduce. This technique includes the identification of the gene of interest, the creation of the replacement gene, it&#39;s incorporation into a vector, and the use of the vector to introduce the new material. In the scope of this patent, we will be using the extraction of the genome, the incorporation of the genome into a vector, and it&#39;s insertion into a diploid cell.  
         [0006]     In the permanent teeth of a human, the DNA stops replicating once the tooth is fully developed. The process of developing these teeth begins at around age six. The tooth of a human grows by allowing new material to develop from the center, and push the old material towards the sides. This will mean that the youngest genetic material will be seen at the edge just below the enamel, in an area called the mantle dentin. Whatever genetic alterations happen to the body will usually occur to reproducing cells. (13) As the fully developed permanent teeth have none, the DNA is unaffected. A person whom is eighty years old will still have six-year-old genetics within them, if the teeth are still present. We are suggesting that the genome found here can be used to fix the damage caused later in life in other cells.  
       BRIEF SUMMARY OF THE INVENTION  
       [0007]     The idea behind this invention is that the genome of affected cells can simply be replaced with DNA that a person already has within them. Once the genome is replaced, some genetic problems will no longer exist.  
         [0008]     Inside the permanent tooth of a person, excluding the wisdom teeth that can develop later, there is a layer of mantle dentin. This layer of cells contains DNA that was created when the person was about 6 years old. Since the cells here do not reproduce, there will be no genetic difference in these cells from the moment they were created until their demise. Despite the rest of the body&#39;s constant cycling of cells, the teeth remain the same. This DNA can be extracted, introduced into a vector, and used to replace the genome of other cells in the body that have had genetic damage. If the genotype of one cell in the body is virtually the same as any other genome-bearing cell in the body, then the DNA is interchangeable. The cells simply express what is needed from the DNA, according to what the cell is and what the cell is supposed to do. If the DNA from the tooth is unchanged from it&#39;s creation at around six-years-old, then the cell it is introduced to will read from six-year-old DNA, despite the age of the person.  
         [0009]     When this genome replacement is used on cancer cells, the DNA will no longer support cancer growth and the cancer will no longer spread. Even if no original permanent teeth are present in the individual, a non-cancerous cell can be used to replace the genome. These cells may be more susceptible to cancer development, but they should be a possible substitute. If this is used on damaged nerve cells, there is a possibility that the nerves will act young again, and reproduce as they did when they were younger. This can aid in the healing process of an amputee, a surgical reattachment, a spinal cord injury, or an older patient who can not easily heal.  
         [0010]     If age is viewed as a genetic problem, then genome replacement will have a key effect on skin properties and hair growth. Since hair loss, as well as hair pigment loss, is a genetic factor for most, the application can be used to regrow and recolor hair. As soon as the cell has the genetic blueprint for hair growth, the rest of the cell can perform to the task. Skin that has been exposed to tanning beds and/or natural light over several years can be exfoliated and introduced to the new genetic material. This should allow the skin to regrow collagen, elastin, and any other protein or polypeptide that it could at the age of six, and at the same levels. This can be performed anywhere on the skin, not just the face. This can be a great advantage from agents such as skin creams that are currently used primarily on the face and neck, as this more permanent solution can be used anywhere on the same person. The result can be more effective than current skin rejuvenation creams as well, as the entire genetic make-up will be reset to the point of a child, despite the person&#39;s age.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0012]     All working surfaces will be decontaminated with a wash sequence of sodium hypochlorite (10%), hydrochloric acid (0.1%), and ethanol (70%). All equipment will be sterilized by autoclaving and decontaminated by exposure to ultraviolet light and bleaching. Novocain will be used to numb the tooth at the gums. A cordless, variable-speed, hand-held electric drill with a 1.0-1.5 mm drill bit, will be used to obtain 0.01-0.02 g of mantle dentin powder from a tooth. A drilling speed of less than 100 revolutions per minute (r.p.m.) was used to minimize heat production, which could result in DNA degradation. The hole or holes drilled will be approximately 1.5-2.0 mm wide and 2.0-3.0 mm deep. Holes will be drilled preferably at the base of the gum line, or on the inside of the tooth to minimize visible damage. Prior to drilling, the drill site will be cleaned with 70-100% ethanol to remove dust and particulate matter. Cotton will be used to keep the area dry. A new, autoclaved drill bit and autoclaved collection tray made from aluminum foil will be used for each patient. The head will be held at an incline during drilling to ensure the tooth powder produced falls into the collection tray. The tooth will be filled as if it were any other dental hole. Tooth powder will be transferred from the tray to a sterile 2 mL tube by careful decanting. This will be packed in ice and stores in a thermal container to be sent to a lab, if the lab work will not be performed on site. After the drilling of each tooth, drill bits and all disposable equipment, including gloves, will be discarded, and working surfaces decontaminated, as described above. (14),(15)  
         [0013]     The tooth powder sample is added to a lysis buffer containing alpha-casein. Next, guanidine thiocyanate (GuSCN) and silica are introduced for 10 minutes. After centrifuging, the supernatant will be removed, and the pellet will be washed with 1 ml of acetone, the process is repeated at least three times, until the sample remaining is pure DNA from the mantle dentin. (16)  
         [0014]     PCR can be used to replicate the genome, as long as a specific primer is not used to isolate a single gene. This will require the DNA, a solution of primers to start the reaction, and a healthy supply of base pairs (Adenine, Guanine, Cytosine, and Thymine). PCR uses a strand of DNA, in this case one for each chromosome, and heats it to 96 degrees C. to separate the DNA strands from their hydrogen bonds. These are then lowered to 68 degrees C. to allow the primers to attach to the template strands of DNA. Once it is lowered to 72 degrees C., the new strands are allowed to recombine. This temperature will need to be maintained for about four hours, to allow for the entire genome to replicate. This will allow one strand to become two. The next cycle of these temperature changes will allow two strands to become four. After twenty cycles, over a million strands are present. This can be accomplished in three days. An alternative to PCR is to grow the mantle dentin from a small sample. This process will allow for more cells to be grown, thus more DNA. Once a sufficient supply of DNA is present, the solution can be introduced to a detergent to create a vector. This will create a Detergent-DNA complexes. One of the most common methods is to use a non-ionic detergent (e.g., lipofectin) that forms a complex with the DNA and by mechanisms still not well understood allow for introduction of DNA into the cell. (17) Some of the solution will be stored in a cold climate for preservation, to ensure that future application will not require more extraction from the patient. What is required for the current application will be placed in the necessary form and distributed.  
         [0015]     Depending on the application, the new Genomic Vector will be introduced to the body by different modes. If the application is being used to fight colon or lung cancers, the solution can be placed in an atomizer and introduced to the cavities via a fine spray. Any cells that the spray touches will be introduced to the new genome, and the cell will decide which strand to use. This will not harm the non-cancerous cells, just readjust their genetic aging. The cancerous cells should revert back to a non-cancerous state. Other cancers, with their own blood supply, can be injected with the solution through their adventitious arteries. As the blood supply feeds every cell of the cancer, it is an ideal pathway for the solution to travel. If introduced as a cosmetic, the patient must first use an abrasive exfoliate, such as a pumice scrub, to relieve any dead skin from the area. Next, the solution will be placed into a hand/body cream that also contains propylene or butylene glycol, glycerine or glyceryl stearate, stearic acid or linoleic acid, sorbitan stearote, and urea, as do most body lotions. After it is applied and the cells accept the DNA, the skin and hair should revert back to the phenotypic properties seen at approximately six years of age. If introduced to a nerve cell, the solution can be brushed directly onto the nerve.
