Halicin (SU-3327) is an experimental drug that acts as an enzyme inhibitor of c-Jun N-terminal kinase (JNK). [ 1 ] [ 2 ] [ 3 ] Originally, it was researched for the treatment of diabetes , [ 4 ] but development was discontinued for this application due to poor results in testing.
Complete deficiency of this enzyme would lead to tyrosinemia III. In rare cases, however, the enzyme is still able to produce the reactive intermediate 1,2-epoxyphenyl acetic acid, but is unable to convert this intermediate to homogentisate.
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, the effect is usually short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD ...
Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of enzyme activities. [1] The majority are due to defects of single genes that code for enzymes that facilitate conversion of various substances into others . In most of the disorders, problems arise due to accumulation of substances which are ...
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
Adenosine monophosphate deaminase deficiency type 1 or AMPD1, is a human metabolic disorder in which the body consistently lacks the enzyme AMP deaminase, [1] in sufficient quantities. This may result in exercise intolerance, muscle pain and muscle cramping. The disease was formerly known as myoadenylate deaminase deficiency (MADD).
The specificity of progesterone as a marker of 21-hydroxylase deficiency, as opposed to deficiency of other enzymes involved in steroid pathways, is still not well studied. [ 184 ] [ 185 ] [ 186 ] Cortisol is one of the two main final products of 21-hydroxylase, and the deficiency of this enzyme may lead to a certain degree of cortisol deficiency.
Enzyme assays (testing a variety of cells or body fluids in culture for enzyme deficiency) are also used to provide definitive diagnosis of one of the mucopolysaccharidoses. Prenatal diagnosis using amniocentesis and chorionic villus sampling can verify if a fetus either carries a copy of the defective gene or is affected with the disorder.
