Propionic and methylmalonic acidemia: antisense therapeutics for intronic variations causing aberrantly spliced messenger RNA. (1/16)
We describe the use of antisense morpholino oligonucleotides (AMOs) to restore normal splicing caused by intronic molecular defects identified in methylmalonic acidemia (MMA) and propionic acidemia (PA). The three new point mutations described in deep intronic regions increase the splicing scores of pseudoexons or generate consensus binding motifs for splicing factors, such as SRp40, which favor the intronic inclusions in MUT (r.1957ins76), PCCA (r.1284ins84), or PCCB (r.654ins72) messenger RNAs (mRNAs). Experimental confirmation that these changes are pathogenic and cause the activation of the pseudoexons was obtained by use of minigenes. AMOs were targeted to the 5? or 3? cryptic splice sites to block access of the splicing machinery to the pseudoexonic regions in the pre-mRNA. Using this antisense therapeutics, we have obtained correctly spliced mRNA that was effectively translated, and propionyl coenzyme A (CoA) carboxylase (PCC) or methylmalonylCoA mutase (MCM) activities were rescued in patients' fibroblasts. The effect of AMOs was sequence and dose dependent. In the affected patient with MUT mutation, close to 100% of MCM activity, measured by incorporation of (14)C-propionate, was obtained after 48 h, and correctly spliced MUT mRNA was still detected 15 d after treatment. In the PCCA-mutated and PCCB-mutated cell lines, 100% of PCC activity was measured after 72 h of AMO delivery, and the presence of biotinylated PCCA protein was detected by western blot in treated PCCA-deficient cells. Our results demonstrate that the aberrant inclusions of the intronic sequences are disease-causing mutations in these patients. These findings provide a new therapeutic strategy in these genetic disorders, potentially applicable to a large number of cases with deep intronic changes that, at the moment, remain undetected by standard mutation-detection techniques.

From June 1998 to May 2007, 9566 urine samples were collected from patients with psychomotor deficits, seizures, vomiting and unconsciousness in Peking University First Hospital. Their urine organic acids profiles were analysed using gas chromatography - mass spectrometry (GCMS), GCMS solution and Inborn Errors of Metabolism Screening System software. In all patients, blood acylcarnitines were analysed using tandem mass spectrometry. One hundred and sixty-eight patients (1.76%) with organic acidurias were detected. Among them, 116 (116/ 168, 69.0%) had methylmalonic aciduria, 63 (54.3%) of these 116 patients had methylmalonic aciduria combined with homocysteinemia. Sixteen (9.5%) of those patients detected with organic acidurias had propionic aciduria, and 15 (8.9%) had multiple carboxylase deficiency. Seven (4.2%) had glutaric aciduria type 1. After dietary treatment, medicine and rehabilitation, clinical improvements were observed in more than half of the patients. Twenty-eight of the 168 patients (16.7%) recovered and led a normal life. The method of urine organic acid analysis by gas chromatography - mass spectrometry and blood acylcarnitines analysis by tandem mass spectrometry have been established and applied successfully in China, namely Beijing, Shanghai, Wuhan and Guangzhou. The prognoses of Chinese patients with organic acidurias have also improved significantly. (+info)Prediction of seizure control in non-ketotic hyperglycemic induced seizures. (6/16)

(+info)Propionic Acidemia is a rare inherited metabolic disorder that affects the body's ability to break down certain proteins and fats. It is characterized by an accumulation of propionic acid and other toxic byproducts in the body due to a deficiency in the enzyme propionyl-CoA carboxylase, which is responsible for breaking down specific amino acids (propionate, isoleucine, methionine, threonine, and valine) found in proteins.
This condition can lead to a variety of symptoms, including vomiting, seizures, developmental delays, hypotonia (low muscle tone), and life-threatening complications such as metabolic acidosis, cardiac dysfunction, and neurological damage. Early diagnosis and management through dietary restrictions, supplementation, and emergency treatment plans are crucial to improve outcomes and prevent severe complications in affected individuals.
Methylmalonyl-CoA decarboxylase is a mitochondrial enzyme that plays a crucial role in the metabolism of certain amino acids and fatty acids. Specifically, it catalyzes the conversion of methylmalonyl-CoA to propionyl-CoA through the decarboxylation of the thioester bond.
The reaction is as follows:
Methylmalonyl-CoA → Propionyl-CoA + CO2
This enzyme requires biotin as a cofactor, and its activity is reduced in individuals with methylmalonic acidemia, a rare inherited metabolic disorder caused by mutations in the MMAB or MCEE genes that encode subunits of the methylmalonyl-CoA decarboxylase enzyme complex.
Deficiency of this enzyme leads to an accumulation of methylmalonic acid and methylmalonyl-CoA, which can cause metabolic acidosis, hyperammonemia, and other symptoms associated with the disorder.
Propionates, in a medical context, most commonly refer to a group of medications that are used as topical creams or gels to treat fungal infections of the skin. Propionic acid and its salts, such as propionate, are the active ingredients in these medications. They work by inhibiting the growth of fungi, which causes the infection. Common examples of propionate-containing medications include creams used to treat athlete's foot, ringworm, and jock itch.
It is important to note that there are many different types of medications and compounds that contain the word "propionate" in their name, as it refers to a specific chemical structure. However, in a medical context, it most commonly refers to antifungal creams or gels.
Inborn errors of metabolism (IEM) refer to a group of genetic disorders caused by defects in enzymes or transporters that play a role in the body's metabolic processes. These disorders result in the accumulation or deficiency of specific chemicals within the body, which can lead to various clinical manifestations, such as developmental delay, intellectual disability, seizures, organ damage, and in some cases, death.
Examples of IEM include phenylketonuria (PKU), maple syrup urine disease (MSUD), galactosemia, and glycogen storage diseases, among many others. These disorders are typically inherited in an autosomal recessive manner, meaning that an affected individual has two copies of the mutated gene, one from each parent.
Early diagnosis and management of IEM are crucial to prevent or minimize complications and improve outcomes. Treatment options may include dietary modifications, supplementation with missing enzymes or cofactors, medication, and in some cases, stem cell transplantation or gene therapy.
Inborn errors of amino acid metabolism refer to genetic disorders that affect the body's ability to properly break down and process individual amino acids, which are the building blocks of proteins. These disorders can result in an accumulation of toxic levels of certain amino acids or their byproducts in the body, leading to a variety of symptoms and health complications.
There are many different types of inborn errors of amino acid metabolism, each affecting a specific amino acid or group of amino acids. Some examples include:
* Phenylketonuria (PKU): This disorder affects the breakdown of the amino acid phenylalanine, leading to its accumulation in the body and causing brain damage if left untreated.
* Maple syrup urine disease: This disorder affects the breakdown of the branched-chain amino acids leucine, isoleucine, and valine, leading to their accumulation in the body and causing neurological problems.
* Homocystinuria: This disorder affects the breakdown of the amino acid methionine, leading to its accumulation in the body and causing a range of symptoms including developmental delay, intellectual disability, and cardiovascular problems.
Treatment for inborn errors of amino acid metabolism typically involves dietary restrictions or supplementation to manage the levels of affected amino acids in the body. In some cases, medication or other therapies may also be necessary. Early diagnosis and treatment can help prevent or minimize the severity of symptoms and health complications associated with these disorders.
Carboxy-lyases are a class of enzymes that catalyze the removal of a carboxyl group from a substrate, often releasing carbon dioxide in the process. These enzymes play important roles in various metabolic pathways, such as the biosynthesis and degradation of amino acids, sugars, and other organic compounds.
Carboxy-lyases are classified under EC number 4.2 in the Enzyme Commission (EC) system. They can be further divided into several subclasses based on their specific mechanisms and substrates. For example, some carboxy-lyases require a cofactor such as biotin or thiamine pyrophosphate to facilitate the decarboxylation reaction, while others do not.
Examples of carboxy-lyases include:
1. Pyruvate decarboxylase: This enzyme catalyzes the conversion of pyruvate to acetaldehyde and carbon dioxide during fermentation in yeast and other organisms.
2. Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO): This enzyme is essential for photosynthesis in plants and some bacteria, as it catalyzes the fixation of carbon dioxide into an organic molecule during the Calvin cycle.
3. Phosphoenolpyruvate carboxylase: Found in plants, algae, and some bacteria, this enzyme plays a role in anaplerotic reactions that replenish intermediates in the citric acid cycle. It catalyzes the conversion of phosphoenolpyruvate to oxaloacetate and inorganic phosphate.
4. Aspartate transcarbamylase: This enzyme is involved in the biosynthesis of pyrimidines, a class of nucleotides. It catalyzes the transfer of a carboxyl group from carbamoyl aspartate to carbamoyl phosphate, forming cytidine triphosphate (CTP) and fumarate.
5. Urocanase: Found in animals, this enzyme is involved in histidine catabolism. It catalyzes the conversion of urocanate to formiminoglutamate and ammonia.
Carbon-carbon ligases are a type of enzyme that catalyze the formation of carbon-carbon bonds between two molecules. These enzymes play important roles in various biological processes, including the biosynthesis of natural products and the metabolism of carbohydrates and lipids.
Carbon-carbon ligases can be classified into several categories based on the type of reaction they catalyze. For example, aldolases catalyze the condensation of an aldehyde or ketone with another molecule to form a new carbon-carbon bond and a new carbonyl group. Other examples include the polyketide synthases (PKSs) and nonribosomal peptide synthetases (NRPSs), which are large multienzyme complexes that catalyze the sequential addition of activated carbon units to form complex natural products.
Carbon-carbon ligases are important targets for drug discovery and development, as they play critical roles in the biosynthesis of many disease-relevant molecules. Inhibitors of these enzymes have shown promise as potential therapeutic agents for a variety of diseases, including cancer, infectious diseases, and metabolic disorders.
Methylmalonyl-CoA mutase is a mitochondrial enzyme that plays a crucial role in the metabolism of certain amino acids and fatty acids. Specifically, it catalyzes the isomerization of methylmalonyl-CoA to succinyl-CoA, which is an important step in the catabolic pathways of valine, isoleucine, threonine, methionine, odd-chain fatty acids, and cholesterol.
The enzyme requires a cofactor called adenosylcobalamin (vitamin B12) for its activity. In the absence of this cofactor or due to mutations in the gene encoding the enzyme, methylmalonyl-CoA mutase deficiency can occur, leading to the accumulation of methylmalonic acid and other toxic metabolites, which can cause a range of symptoms including vomiting, dehydration, lethargy, hypotonia, developmental delay, and metabolic acidosis. This condition is typically inherited in an autosomal recessive manner and can be diagnosed through biochemical tests and genetic analysis.
Methylmalonic acid (MMA) is an organic compound that is produced in the human body during the metabolism of certain amino acids, including methionine and threonine. It is a type of fatty acid that is intermediate in the breakdown of these amino acids in the liver and other tissues.
Under normal circumstances, MMA is quickly converted to succinic acid, which is then used in the Krebs cycle to generate energy in the form of ATP. However, when there are deficiencies or mutations in enzymes involved in this metabolic pathway, such as methylmalonyl-CoA mutase, MMA can accumulate in the body and cause methylmalonic acidemia, a rare genetic disorder that affects approximately 1 in every 50,000 to 100,000 individuals worldwide.
Elevated levels of MMA in the blood or urine can be indicative of various metabolic disorders, including methylmalonic acidemia, vitamin B12 deficiency, and renal insufficiency. Therefore, measuring MMA levels is often used as a diagnostic tool to help identify and manage these conditions.
I am sorry for any confusion, but "Pentanoic Acids" is not a recognized medical term or concept. Pentanoic acid, also known as valeric acid, is an organic compound with the formula CH3CH2CH2CH2CO2H. It is a fatty acid with five carbon atoms, and it may have some uses in industry, but it does not have specific relevance to medical definition or healthcare.
A mutation is a permanent change in the DNA sequence of an organism's genome. Mutations can occur spontaneously or be caused by environmental factors such as exposure to radiation, chemicals, or viruses. They may have various effects on the organism, ranging from benign to harmful, depending on where they occur and whether they alter the function of essential proteins. In some cases, mutations can increase an individual's susceptibility to certain diseases or disorders, while in others, they may confer a survival advantage. Mutations are the driving force behind evolution, as they introduce new genetic variability into populations, which can then be acted upon by natural selection.
Diabetic ketoacidosis (DKA) is a serious metabolic complication characterized by the triad of hyperglycemia, metabolic acidosis, and increased ketone bodies. It primarily occurs in individuals with diabetes mellitus type 1, but it can also be seen in some people with diabetes mellitus type 2, particularly during severe illness or surgery.
The condition arises when there is a significant lack of insulin in the body, which impairs the ability of cells to take up glucose for energy production. As a result, the body starts breaking down fatty acids to produce energy, leading to an increase in ketone bodies (acetoacetate, beta-hydroxybutyrate, and acetone) in the bloodstream. This process is called ketosis.
In DKA, the excessive production of ketone bodies results in metabolic acidosis, which is characterized by a lower than normal pH level in the blood (< 7.35) and an elevated serum bicarbonate level (< 18 mEq/L). The hyperglycemia in DKA is due to both increased glucose production and decreased glucose utilization by cells, which can lead to severe dehydration and electrolyte imbalances.
Symptoms of diabetic ketoacidosis include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, fatigue, fruity breath odor, and altered mental status. If left untreated, DKA can progress to coma and even lead to death. Treatment typically involves administering insulin, fluid replacement, and electrolyte management in a hospital setting.
Hyperaldosteronism is a medical condition characterized by the overproduction of aldosterone, a hormone produced by the adrenal glands. Aldosterone helps regulate sodium and potassium balance and blood pressure by promoting sodium retention and potassium excretion in the kidneys.
There are two types of hyperaldosteronism: primary and secondary. Primary hyperaldosteronism is caused by an overproduction of aldosterone from an abnormality within the adrenal gland, such as a tumor (Conn's syndrome) or hyperplasia. Secondary hyperaldosteronism occurs when there is an excess production of renin, a hormone produced by the kidneys, which then stimulates the adrenal glands to produce more aldosterone. This can be caused by various conditions that affect kidney function, such as renal artery stenosis or heart failure.
Symptoms of hyperaldosteronism may include high blood pressure, low potassium levels (hypokalemia), muscle weakness, and frequent urination. Diagnosis typically involves measuring aldosterone and renin levels in the blood, as well as other tests to determine the underlying cause. Treatment depends on the type and cause of hyperaldosteronism but may include medications, surgery, or lifestyle changes.
"Malonates" is not a recognized medical term. However, in chemistry, malonates refer to salts or esters of malonic acid, a dicarboxylic acid with the formula CH2(COOH)2. Malonic acid and its derivatives have been used in the synthesis of various pharmaceuticals and chemicals, but they are not typically associated with any specific medical condition or treatment. If you have encountered the term "malonates" in a medical context, it may be helpful to provide more information or seek clarification from the source.
