Mitochondria Research Paper

Reproductive cloning is similar to IVF because it also brings embryo into existence. This potential infertility treatment involves the creation of embryo using the genetic material of the parent. This is done by extracting nucleus from the person’s somatic cell and transfer into an oocyte through somatic cell nuclear transfer. Thus, the processed oocyte

In the United Kingdom alone, 150 new born children per year suffer from life threatening, mitochondrial diseases. These diseases vary in severity from person to person, making them difficult to diagnose, and they inflict an array of ailments such as neurological problems, muscle weakness, visual or auditory impairments, heart, liver, and kidney disease,

The most public concern about mitochondrial replacement is the unsureness of the new technology on human offspring. Pronuclear transfer and mitochondrial spindle transfer techniques have only been used on animal subjects such as rhesus monkeys and mice and human zygotes that were abnormally fertilized (unipronuclear or tripronuclear) (Craven at el. 82). Because PNT and MST were used on animals- which does not have the same genetic makeup as humans- and abnormal human zygotes it is impossible to know exactly what effect the procedure will have on a human offspring. According to Reinhardt, Dowling, and Morrow, “safety studies in humans have only tracked health through blastocysts stage in macaques to three years. The results from mice and

Mitochondria are often referred to as the powerhouses of the cells. They generate the energy that our cells need to do their jobs. For example, brain cells need a lot of energy to be able to communicate with each other and also to communicate with parts of the body that may be far away, to do this substances need to be transported along the cells, which needs lots of energy. Muscle fibres also need a lot of energy to help us to move, maintain our posture and lift objects.

Mitochondrial disorders may be caused by mutations which are acquired or inherited in mitochondrial DNA (mtDNA) or in nuclear genes that code for mitochondria. Disorders can also be a result of environmental stress, adverse

Mitochondrion’s most important job is to produce energy through cellular respiration. Mitochondria does this by taking in nutrients from the cell itself, breaking it down and then turning it into energy. Then, the energy gathered is utilised by the cell to carry out various functions, hence this organelle is also known as the ‘powerhouse’ of the cell. Its purpose is to keep the cell full of energy.

“Scientists create three parent babies”, headlines screamed; many people were outraged, saying that is was unnatural, and that scientists were arrogant to think they could “play god”. In reality, mitochondrial donation isn’t as scary as it sounds. The mitochondria are small organelles in cells that helps create energy to keep the cell functioning. Until recently, we thought that was the primary function of the mitochondria, however, we now know that the mitochondria contain vital DNA. This segment of DNA is tiny compared to the rest of the genome, containing only 37 genes. However, if a piece of this DNA is damaged or mutated, it can lead to genetic diseases such as Leigh’s Syndrome, a brain disorder that progresses through childhood. A person experiences delayed development, motor issues, and muscle weakness. Mitochondrial donation can fix problems with faulty mitochondrial DNA. If it is known that the mother’s egg contains a mutation in the mitochondria, they can take the nucleus (where all genetic material is stored) out, remove the nucleus from an egg with healthy mitochondria, and insert the mother’s nucleus. The egg is then fused with the father’s sperm, placed in the mother’s uterus, and the embryo now has healthy mitochondria. Over 99% of the embryo’s DNA will be from the two parents, and only a small portion from the donor mitochondria, which only determines mitochondria

Mitochondrial play a crucial role in energy transduction of myocardium. Cellular and mitochondria metabolism observed in the course of hyperglycemia is associated with excessive production of reactive oxygen species (ROS). Among other factors involve in ROS production, is intracellular concentration of glucose secreted by the pancreatic β cells. Glucose play a key role in the mitochondrial-dependent oxidative reaction thus involvement of insulin resistance contribute to the influx of calcium ion Ca2+, generating excessive ROS. Therefore, mitochondrial radical ROS production in response to hyperglycemia is associated with Ca2+ concentration linked to cardiac mitochondrial dysfunction.

Gamete Intrafallopian Transfer is a process of assisted reproductive technology. It was first developed in the 1980s in America as a variation of In Vitro Fertilisation. GIFT ca be used for infertile couples who have ovulation disorders, hormone imbalances, uterus or cervical disorders, endometriosis, their age is declining or have unexplained fertility issues. But do these women who undertake GIFT due to these infertility issues have a high success rate of pregnancy? GIFT is conducted by retrieving the eggs from the ovaries by a laparoscopy along with the sperm where they are cleaned, mixed together and transferred back into the fallopian tube to allow fertilisation to occur naturally. Some advantages to GIFT include that the church accepts the procedure and that GIFT is less ethically debateable. Although, there are numerous disadvantages such as the success rate is low, there are risks that the baby will have disabilities and women may have an ectopic pregnancy. The future of GIFT will eventually be replaced by other technologies like IVF or Intracytoplasmic Sperm Injection which will impact on

Fertility doctors have discovered a new procedure for women who have mitochondrial diseases and want to have healthy children. The procedure is called a mitochondrial transfer, using the DNA of both parents and a mitochondria from a donor. This process is not used often and it is not very well known in the United States. A procedure similar to this one was used in the 1990s and was unsuccessful, this new idea leaves people questioning if this one will be better than the last. The procedure of having a baby with the DNA of three people should not be used because this case is one of the first successful attempts and this process is only legal in two countries.

In relation to mitochondria, abnormality in appearance occurred during normal muscle weakness, and no mitochondria fragments left in a neuron occurred a few weeks before paralysis (Kong and Xu 1998). Abnormalities in mitochondria were prominent in motor neurons before muscle weakness began, and the link between mitochondria degeneration and motor neuron death is the mutant SOD1 gene. These results showed that mitochondria deterioration is associated with the beginning of the disease, and SOD1 toxicity is the feature that damages the mitochondria; this is also related to motor neuron death in the fact that this triggers the deterioration of motor neuron cells (Kong and Xu 1998). In other words, damage to mitochondria is the center of motor neuron degeneration. This study explained the physiological steps to muscle weakness in patients with

Mitochondria are double membrane bound organelles that are essential for producing 95% of our cells energy in the form of ATP1. We have around a hundred to a thousand of these organelles present in each of our cells and they are unique to other organelles in that they contain their own DNA1. But why is this? And how has this benefited the cell in evolutionary terms? Mitochondria are most commonly thought of as the ‘power house’ of the cell due to ATP production being their main function however they have also evolved with many other abilities. I plan to focus how the mitochondria came about and how its structure and function have changed. As mitochondria have many functions I will be looking specifically into mitochondria’s roles in ATP production

The process begins with the extraction of the nucleus, an organelle of the cell that contains a copy of the body’s entire set of DNA, of the egg of the mother, who has the mitochondrial disease. The nucleus of the female donor’s healthy egg is removed and replaced with the nucleus of the mother. This process is done to more than just one egg just in case one of the fertilized eggs does not work. The group of eggs are fertilized and the embryos (fertilized egg) are then inserted into the mother. Mitochondrial DNA, however, does not in anyway affect or change the child’s physical appearance. The resulting baby’s DNA is still half from mom and half from dad with only the mitochondrial DNA inherited from the donor and most importantly, is not
