Adrenal Hyperplasia Type 3 or Congenital Adrenal Hyperplasia Due to 21-Hydroxylase DeficiencyMus musculus
Adrenal hyperplasia type 3, also called Congenital adrenal hyperplasia due to 21-hydroxylase deficiency, is caused by a defect in the CYP21A2 gene which codes for Steroid 21-hydroxylase (21-hydroxylase). Steroid 21-hydroxylase catalyzes hydroxylation of 17-hydroxyprogesterone to 11-deoxycortisol in the glucocorticoid pathway from pregnenolone to cortisol. It also catalyzes hydroxylation of progesterone to 11-deoxycorticosterone (DOC) in the mineralocorticoid pathway on its way from pregnenolone to aldosterone. A defect in this enzyme results in accumulation of 17-Hydroxyprogesterone, progesterone and 17a-Hydroxypregnenolone, androstenedione, and testosterone; decreased levels of cortexolone, deoxycorticosterone, aldosterone and cortisol. Symptoms include salt-wasting crises in infancy due to the lack of aldosterone, like spitting, poor weight gain, vomiting, severe dehydration, and circulatory collapse. The high level of testosterone results in virilization and genital ambiguity of female infants.

Adrenal Hyperplasia Type 5 or Congenital Adrenal Hyperplasia Due to 17 alpha-Hydroxylase DeficiencyHomo sapiens
Adrenal hyperplasia type 5 (AH5) also known as Congenital Adrenal Hyperplasia Due to 17 alpha-Hydroxylase Deficiency is a rare inborn error of metabolism (IEM) and autosomal recessive disorder of cortisol and sex steroids synthesis caused by a defect in the CYP17A1 gene which codes for Steroid 17-alpha-hydroxylase/17,20 lyase. These 2 enzymes catalyze pregnenolone and progesterone to their 17-hydroxy forms in steroidogenesis and mediate three key transformations in cortisol and sex steroid synthesis. This disorder is characterized by a decrease in both cortisol and sex steroids and increase in mineralocorticoids. Symptoms of the disorder include mild hypocortisolism, ambiguous genitalia in genetic males or failure of the ovaries to function at puberty in genetic females, and hypertension. Treatments for Hypertension and mineralocorticoid excess is done with glucocorticoid replacement. Genetically female patients need female hormone replacement to induce puberty and regulate menses. Surgery may be needed for males with ambiguous genitalia. Testosterone must be replaced for genetically males (XY) to induce puberty and continued throughout adult life. It is estimated that Adrenal hyperplasia type 5 affects 1 in 1 million individuals worldwide.

Adrenoleukodystrophy, X-LinkedRattus norvegicus
Adrenoleukodystrophy (ALD) is an X-linked recessive transmission disease. Central nervous system signs and symptoms have been consistently more prominent than signs of adrenal involvement. Behavioral changes are the most common initial finding and range from aggressive outbursts to withdrawal. Such behavior is generally accompanied by a gradually failing memory and poor school performance. Loss of vision is an early finding in some patients and is a prominent feature at some stage in most affected individuals. The initial visual loss appears as homonomous hemianopsia in some individuals and is usually associated with intact pupillary reflexes. Optic atrophy is less common as an initial finding but eventually develops in almost all cases. Gait disturbance is also an early finding and as is stiff-legged, unsteady and accompanied by hyperreflexia. In almost all cases there is spastic quadraplegia and a variable degree of decorticate posturing. Hearing loss, dysarthria and dysphagia develop at about the same time as gait disturbance. Seizures are a typical symptom in many affected individuals in the the end stages of the disease progression.

Aerobic Glycolysis (Warburg Effect)Homo sapiens
The Warburg Effect refers to the phenomenon that occurs in most cancer cells where instead of generating energy with a low rate of glycolysis followed by oxidizing pyruvate via the Krebs cycle in the mitochondria, the pyruvate from a high rate of glycolysis undergoes lactic acid fermentation in the cytosol. As the Krebs cycle is an aerobic process, in normal cells lactate production is reserved for anaerobic conditions. However, cancer cells preferentially utilize glucose for lactate production via this “aerobic glycolysis”, even when oxygen is plentiful. The Warburg Effect is thought to be the result of mutations to oncogenes and tumour suppressor genes. It may be an adaptation to low-oxygen environments within tumours, the result of cancer genes shutting down the mitochondria, or a mechanism to aid cell proliferation via increased glycolysis. Proliferation may occur due to the accumulation of glycolytic intermediates (which lead to the production of nucleotides, amino acids, and fatty acids) after the final enzymatic reaction of glycolysis (phosphoenolpyruvate into pyruvate) is slowed down. This reaction produces lactic acid which leads to a low pH microenvironment and the lactate shuttle can activate angiogenesis factors from surrounding cells. The Warburg Effect involves numerous pathways, including growth factor stimulation, transcriptional activation, and glycolysis promotion.
