Because steroids and sterols are lipid -soluble, they can diffuse fairly freely from the blood through the cell membrane and into the cytoplasm of target cells. This is in contrast to the actions of non-steroid hormones, which are water-soluble typically peptide hormones, acting through membrane bound receptors and intracellular second messenger systems to exert their effects. In the cytoplasm, the steroid may or may not undergo an enzyme -mediated alteration such as reduction, hydroxylation, or aromatization. In the cytoplasm, the steroid binds to the specific receptor, a large metalloprotein. Upon steroid binding, many kinds of steroid receptor dimerize : Two receptor subunits join together to form one functional DNA -binding unit that can enter the cell nucleus. In some of the hormone systems known, the receptor is associated with a heat shock protein , which is released on the binding of the ligand , the hormone. Once in the nucleus, the steroid-receptor ligand complex binds to specific DNA sequences and induces transcription of its target genes . [2] [6] [7] [8]

Prednisone is a drug that belongs to the corticosteroid drug class, and is an anti-inflammatory and immune system suppressant. It's used to treat a variety of diseases and conditions, for example: inflammatory bowel disease (Crohn's disease and ulcerative colitis), lupus, asthma, cancers, and several types of arthritis.

Common side effects are weight gain, headache, fluid retention, and muscle weakness. Other effects and adverse events include glaucoma, cataracts, obesity, facial hair growth, moon face, and growth retardation in children. This medicine also causes psychiatric problems, for example: depression, insomnia, mood swings, personality changes, and psychotic behavior. Serious side effects include reactions to diabetes drugs, infections, and necrosis of the hips and joints.

Corticosteroids like prednisone, have many drug interactions; examples include: estrogens, phenytoin (Dilantin), diuretics, warfarin (Coumadin, Jantoven), and diabetes drugs. Prednisone is available as tablets of 1, , 10, 20, and 50 mg; extended release tablets of 1, 2, and 5mg; and oral solution of 5mg/5ml. It's use during the first trimester of pregnancy may cause cleft palate. This medicine is secreted in breast milk and can cause side effects in infants who are nursing. You should not stop taking prednisone abruptly because it can cause withdrawal symptoms and adrenal failure. Talk with your doctor, pharmacist, or other medical professional if you have questions about beta-blockers. Talk with your doctor, pharmacist, or other medical professional if you have questions about prednisone.

FIGURE 2. Major Pathways of Steroid Biosynthesis.
The pathways outlined here are common to the adrenals, the gonads and, to some extent, to the fetoplacental unit. The first committed step is the conversion of cholesterol to pregnenolone, catalysed by the P-450scc enzyme, which is under pituitary hormone control (ACTH or LH depending on the tissue). Cholesterol side-chain removal is blocked specifically by aminoglutethimide , a steroid biosynthesis inhibitor. From pregnenolone, steroid biosynthesis can proceed either through the so-called "delta-5" pathway (17α-hydroxypregnenolone, dehydroepiandrosterone, testosterone), or through the "delta-4" pathway (progesterone onwards). Progesterone is the starting point for mineralocorticoid synthesis, whereas glucocorticoids are derived from its metabolite, 17α-hydroxyprogesterone. Estrogens are formed from androgens (androstenedione and/or testosterone). Most reactions are irreversible (as denoted by a single arrow). Reversible reactions (double arrows) depend on cofactor availability (. the NADP/NADPH ratio). [Abbreviations used here for the various enzymes are listed in the figure].
