How to Detect and Treat Genetic Diseases

There are many genetic diseases which may become dangerous if we do not know how to prevent early. Gene therapy is one of the prominent ways of treating genetic diseases. According to gene therapy, the genes are inserted into individual cells and tissues. Depending on the disease, the specific genes are corrected and inserted into the cells. However, there are still numerous researches based on gene therapy for various kinds of genetic disorders.

For people affected by some genetic diseases, antibiotics and a potent immune system hormones are used during the treatment. However, it actually does not cure the disease. It only reduces the infection, and consequently the vigor of the disease.

Some studies have proved that genetic diseases can be treated by altering the method of conversion of DNA into proteins. This method of treatment worked well for some genetic diseases such as Spinal muscular atrophy. This method is being tested for treating few other genetic diseases too. Gene transfer methods, which were initially used in animals like dogs are now being used to treat human eye diseases.

Gene identification is done as a part of treatment for genetic eye diseases. This will help in identifying the appropriate treatments for some genetic eye diseases and hence getting treated on a timely basis like wearing appropriate glasses becomes the absolute requirement of the patient. Moreover, gene identification also helps in preventing few genetic eye diseases.

However, obesity, which is one of the most common genetic diseases or disorders, as the case may be, is treated with a healthy diet program or weight loss program. Regular exercises will help in losing some weight. Yet, it is essential to consult a physician or geneticist to confirm that your obesity is due to genetic disorder only. The weight of your family members has to be taken into account for confirming that it is a genetic disorder.

People having diabetes (type I) must get their children regularly checked. They must prevent their family members including children from taking excess sugar or sweets. Diabetes can be controlled by regular medication. Cardio exercises can keep the insulin level in control. It is one of the most common genetic diseases, which actually has no permanent cure.

Not all genetic disorders can be cured. There are however drugs to control most of these genetic diseases or disorders. These drugs can only control or reduce the vigor of the disease. Treatments for many genetic diseases are still under study. Unless proper treatments are being introduced, it is essential to pay more attention to prevention of these type of diseases.

All You Need To Know About Gene Therapy

The human body is comprised of various organs that each have a specialized role in maintaining the proper health of a person. The brain is involved in thought, reasoning and, in general, controlling our actions; the heart sends blood around our body supplying all the organs with oxygen; the lungs oxygenate our blood thus providing the energy we need to function; the stomach, kidneys, liver, intestine and bladder extract nutrients from our diet and remove toxins. Each organ plays an essential and unique part keeping us alive.

To function correctly, an organ comprises billions of cells of different types, each arranged in tightly controlled structures that form the overall architecture of the body. It is the cells that are in point of fact responsible for the proper functioning of the organ. If an organ is malfunctioning, then to treat it, we must restore the smooth operation of these cells.

Basic Cell Biology

Most cells are made up of similar components: a nucleus, the part of the cell containing genetic information; a variety of organelles, small elements that carry out processes such as energy production, much like the way that different organs perform specific functions of the body (e.g. lysosome, mitochondrion, Golgi etc); the cytoplasm, the liquid medium that comprises the cell, and the plasma membrane, the element that gives the cell its shape.

The nucleus codes for all the information required to produce the cell. Each organelle and cellular makeup are made up of protein, sugars, and lipids (fatty compounds), and the nucleus not only encodes for the production of each of these components but also the information necessary for their correct assemblage and final position. This information is enclosed within the cell's DNA, which is the principal constituent of the nucleus and is tightly condensed in a highly organized manner in the nuclear membrane.

Our Genes

Within the nucleus, our DNA is arranged into 23 sets of chromosomes (or 22 pairs, and one X chromosome and Y chromosome if you are male). These 46 chromosomes are communally known as the human genome, as they contain all of the genes that act as the blueprint for the human body. We can imagine of our DNA as a long linear molecule that is split into 46 separate parts (i.e. the chromosomes). Within each chromosome, there are thousands of genes lined up one after the other one after another and split by intergenic regions. Each gene is a unit of DNA that encodes for a certain protein, with a unique function. It is the combination of many discrete proteins, and their actions on other molecules like sugars and lipids, that comprises the basis of the organelle, and by consequence, of the cell itself.

So one can imagine that in a pathological situation, where an organ is malfunctioning, we can time and again trace the dysfunction to a particular protein that is not working correctly. These protein malfunctions can either be genetic, or acquired in the course of

• An infection,
• An autoimmune reaction,
• Untimely tissue degeneration
• The formation of cancer.

So, in any condition where a disease can be traced to a malfunction of protein, or where a protein of known activity can restore the proper functioning of a cell, gene therapy can be used. This is just because we can now use the correct gene to deliver the exact type of the protein to the cell we want to fix. It is significant to note that by delivering genes exclusively into diseased cells, there is no opportunity of conveying this new genetic information in the future to our children. To do so, our germ cells would have to be the target for gene transfer, a process that is illegal, and extremely technically demanding.

Application of Genetic Therapy

Effectual gene transfer into human cells is known to be the major challenge the Gene Therapy. Gene transfer vector have to be safe, introduce its DNA cargo into a satisfactorily large amount of cells to create a biological response and mediate transcription of the desired gene for a long duration. Identifying a vector that meets these criteria has proven to be a testing task.

Gene Therapy is more often than not used in pathologic conditions where A cells of a distinct organ or system do not function correctly because they do not have the right protein WHICH is required to perform the desired task.

Synthetic Biology - A Possible Future Niche

There are constant strives and innovations going on in the medical world. One of the latest ideas is synthetic biology, which is quite a scientific subject matter. Some of the top scientists in the field are still a little unsure of exactly how synthetic biology will work, but it is not stopping the medical field from advancing in the field. Simply put, synthetic biology is the process of shuffling genes around to make human cells from scratch without actually using any natural cells.

It is thought that this type of biology can be used to make T-cells, which may be able to fight cancers and other diseases which are typically incurable. There is of course controversy over making human cells out of nonhuman materials. There is the argument that it is an unnatural process and that it should not be attempted even if it does have its benefits. It is the benefits however that scientists and other medical professionals are fighting for. Some countries have even gone as far as banning synthetic biology because they are afraid of the technology falling into the wrong hands.

At this point, the studies are only studies, and nothing concrete has invented or implemented. Even though synthetic cells have created in labs, these cells have not been used in any current medical treatments. It could be years or even decades before the public would see any benefit from the study of synthetic biology, but this is a direction that medicine is keeping an eye out for.

Synthetic Biology - The Future of Chemical Manufacturers

Advancing technology and new uses for old substances may substantially change the future for chemical manufacturers. Synthetic biology as a factor of applied biotechnology will produce some innovative new ways for manufacturing facilities to produce the vast amount of chemicals required by various industries.

Chemical Manufacturing in the Past

In the past, plant matter supplied the raw material to produce chemicals. It was not until petroleum came along that a wider variety of plastics and other substances were invented. Indeed, this was viewed as one of the greatest advances in the 20th century.

Now, due to advances in genetic engineering, new possibilities exist for the manufacture of chemicals through the use of synthetic biology.

How It Works

The purpose of the synthetic biologist is to build an animal from injury. They are using an appearance comparable to that of others type of engineering in the design and construction of systems that will support this new technology.

Algae group are fed biomass made from natural material such as sugarcane in the deep, bioengineering that allow the algae to produce oil outgoing in the process of photosynthesis.

There is no doubt synthetic biology still has a long way to go toward becoming the new replacement for non-renewable sources used by chemical manufacturers. However, the possibilities are exciting, and this modern field offers hope for the creation of cheaper, sustainable materials.

Organic Food versus Genetically Modified Food

This is the era of ultimate technological advancements. With each passing day, there is emergence taking place in every single field of life. Be it, computers, robotics, house accessories, machinery and now food even. Food is also being genetically engineered according to the needs of people of day to day. There are several advantages as well as disadvantages of using Genetically Modified Food.

Organic food is basically referred to the production of food in such a way that it grows only in the natural environment. Everything is kept natural, from food to all the processes to gain agricultural produce. No medicines or steroids are fed. Fertilizers used are all organic. There is not even a single element of artificiality.

On the other hand, whenever you are producing genetically modified food, make use of artificially altered DNA of different kind of organisms. The environment provided to them is also artificial. The food given includes different forms of steroids and yield enhancing medicines.

The main reason behind producing genetically modified organisms is to meet the demand of the growing population. The number of people in the world is growing day by day and in order to meet this very increasing demand, they need to have more yield. Yield can only be enhanced in this way by giving in the artificial environment to them for growth.

There are several disadvantages of using GMO’s (genetically modified organisms). First of all, there are so many deaths encountered due to the use of GMOs. This is mainly because when you genetically engineer the food, they are many different particles induced in the food which causes allergy to people. These days this can be improved as well by writing the allergy cautions at front of different food packages. This makes people well aware.

Moreover, there are so many cancerous elements inculcated in the food. This happens in a very uninformed way. It happens usually that people are not mindful of this fact and keep eating those products. Sometimes, there are toxins present on the outer surface. So, it is better to remove the outer of vegetables or fruits when you are eating those foods. Sometimes, these toxins are induced in the fruit or vegetable itself. This is when it becomes cancerous. It is when the food is highly dangerous for health. Instead of having positive effects on health, it will have negative effects pertaining to those foods.

In addition to this, the genetically modified organisms are high yielding. The produce gained from such organisms are in great amount. This is mainly due to the heavy amounts of pesticides and insecticides. These are very harmful to health due to several toxins and harmful particles present in there.

In the core and crust, it is not good for health to eat genetically engineered food. This is mainly because of the harmful effects on health. Although it helps to enhance the yield and being productive. But, in the end, everyone should be careful enough. Everyone should read the ingredients before buying to be aware of allergens.
