Many illnesses, such as schizophrenia, Alzheimer’s disease, Parkinson’s disease and bipolar disorder are associated with oxidant stress. Yet, increasing levels of free antioxidants by supplementing with more than RDA amounts of vitamin E, beta-carotene and vitamin C does not treat these illnesses.
Increasing levels of free antioxidants via supplmentation could be much worse than useless. Before iron can be absorbed iron must be reduced from Fe3+ to Fe2+. Antioxidants like vitamin C, vitamin E , beta-carotene and quercetin could one way or other promote the reduction of Fe3+ to Fe2+ in the gastrointestinal tract which would increase absorption. The goal, however, is to delay iron absorption as long as feasible.
There is oxidant stress in lots of illnesses but this could be due to dysregulation of selenoproteins and dysregulation of iron metabolism which would not be fixed by increasing levels of free antioxidants with supplemental vitamin C, vitamin E , beta-carotene, quercetin etc.
Supplementing with free antioxidants could be associated with very subtle but serious mineral dysregulations which would basically be undiagnosable.
In Friedreich ataxia iron-sulfur clusters are not formed, due to deficiencies in frataxin which results in iron accumulation in mitochondria. The relevant point is that problems in iron-sulfur cluster formation can be associated with iron accumulation in mitochondria and iron toxicity. The point I have been making is that there are difficulties in synthesizing iron-sulfur clusters in many neurological illnesses due to dysregulation of the transsulfuration pathway which synthesizes L-cysteine. L-cysteine supplies sulfur for iron-sulfur cluster formation.
Iron chelators are now being investigated as treatments for Alzheimer’s disease and Parkinson’s disease. If iron is being accumulated in cells in Alzheimer’s disease and Parkinson’s disease due to difficulties in iron-sulfur cluster formation then iron chelators would not be appropriate treatments. Iron-sulfur cluster formation is increased by supplemental iron. Iron chelators by decreasing iron would decrease iron–sulfur cluster formation leading to iron accumulation in mitochondria and iron toxicity.
Inflammation is associated with schizophrenia, Parkinson’s disease and Alzheimer’s disease. A point I have strongly stressed is that the transsulfuration pathway is dysregulated in many neurological illnesses. With the transsulfuration pathway dysregulated there will de decreased levels of L-cysteine which is synthesized via the transsulfuration pathway. Decreased levels of l-cysteine will lead to decreased levels of taurine. Taurine is synthesized from L-cysteine. The bile acid, taurocholate, is synthesized from taurine. With low levels of taurine, essential fatty acids are not absorbed sufficiently. Inflammation in schizophrenia, Parkinson’s disease and Alsheimer’s disease could be due to low levels of taurine which leads to failures to absorb sufficient fatty acids with inflammation resulting.
Taurine chloramine which is synthesized from taurine is also an important immunomodulatory.
There are infectious diseases subdivided into bacterial and viral diseases, there is cancer where there are many sorts of cancer, there is heart disease, lung disorders etc. There could be a new disease class. There could be epigenetic disorders where there is common origin for a wide range of epigenetic disorders. With epigenetic mechanisms dysregulated many different diseases can arise as there are many different ways genes and histones can become inappropriately methylated. My idea is that a dysregulation of aconitase 1 can dysregulate iron metabolism and decrease 2-oxogularate synthesis which will in turn dysregulate TET enzymes, which demethylate DNA, and dysregulate Jumonji domain-containing proteins, which demethylate histones. Dysregulation of TET enzymes and dysregulation of Jumonji domain-containing proteins can play out many different ways in terms of inappropriate DNA methylation and inappropriate histone methylation whereby many different diseases can arise. Though many different diseases can arise from dysregulations of aconitase 1, iron metabolism and 2-oxoglutarate synthesis prevention of a range of illnesses could be achieved by the same treatment. For example, a treatment than prevents schizophrenia could also prevent Alzheimer’s disease and Parkinson’s disease. The Treatment presented in the Treatment section is not ready for home use, however, a Moon shot would not be necessary to get the treatment to a state where family doctors could prescribe a treatment which would prevent a range of chronic illnesses from schizophrenia, to Alzheimer’s disease, to Parkinson’s disease. What is needed is a launch ten weather balloons into the high atmosphere then collect and analyze data kind of effort.
Aconitase 1 (ACO1) is an enzyme in the citric acid cycle. Aconitase 1 is a dual function protein. Upon loss of an iron-sulfur cluster ACO1 becomes iron regulatory protein 1 (IRP1). IRP1 affects stability of mRNA transcripts of proteins involved in iron metabolism such as ferritin, DMT1, which is an iron transporter, and ferroportin, which is the only known iron exporter. Increasing iron levels switches IRP1 to ACO1 as IRP1 gains an iron-sulfur cluster. With a 4Fe-4S iron-sulfur cluster ACO1 can participate in the citric acid cycle and generate ATP.
On-off disorders could be are due to wide swings in ACO1/IRP1 and the TCA cycle. Suddenly the TCA cycle is functioning and then the TCA cycle is not functioning while at the same time there are swings in the regulation of iron regulated proteins. Dietary iron could be associated with swings in on-off symptoms.An added wrinkle is that high IRP1 levels adversely affects copper absorption, however, copper is needed for iron metabolism.
I very much like answers that answer everything. On-off symptoms are prominent in lots and lots of illnesses. There is, of course, bipolar disorder but a lot of depressions cycle rapidly and are some of the most difficult depressions to treat. Parkinson’s disease has a very prominent on-off symptoms. In Parkinson’s disease there are indications that iron metabolism is dysregulated. There could be a unitary explanation for cycling disorders.
Iron chelators are being clinically tested in a number of neurodegenerative illnesses such as Alzheimer’s and Parkinson’s disease . I do not think iron chelation is going to work. In fact I think iron chelators will make Alzheimer’s and Parkinson’s worse. I very much hope I am mistaken. The difficulty isn’t iron per se but rather dysregulation of iron regulated biological processes. Sensible ideas are wrong all the time. Iron chelation is a very sensible approach to treatment of Alzheimer’s and Parkinson’s which I think is going to be disastrous.
