sodium-independent organic anion transport

Definition

Target type: biologicalprocess

The directed, sodium-independent, movement of organic anions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:go_curators]

Sodium-independent organic anion transport is a complex process that facilitates the movement of various organic anions across cell membranes without the direct involvement of sodium ions. These anions encompass a wide range of molecules, including bile acids, steroid conjugates, drugs, and various metabolites. The mechanism of transport typically involves carrier proteins embedded within the cell membrane, which bind to the organic anions and facilitate their movement across the membrane. This process is driven by a concentration gradient or electrochemical potential, meaning that anions move from an area of high concentration to an area of low concentration or from an area of high electrical potential to an area of low electrical potential.

The transport process is often characterized by its selectivity, meaning that specific carrier proteins may exhibit preference for certain types of organic anions. This selectivity is influenced by the chemical structure of the anions and the binding sites on the carrier proteins.

One of the key aspects of sodium-independent organic anion transport is its role in various physiological processes, including:

* **Bile acid excretion:** The liver secretes bile acids into the bile canaliculi, a process facilitated by sodium-independent organic anion transporters. This excretion is crucial for lipid digestion and absorption in the gut.
* **Drug metabolism and elimination:** Many drugs are metabolized in the liver and subsequently excreted in the bile or urine. Sodium-independent organic anion transporters play a significant role in these processes by transporting drug metabolites across cell membranes.
* **Hormone transport:** Steroid hormones, such as estrogen and testosterone, are transported across cell membranes by sodium-independent organic anion transporters. This transport is essential for hormone signaling and regulation.
* **Cellular detoxification:** Sodium-independent organic anion transporters contribute to cellular detoxification by removing toxic substances, such as xenobiotics, from cells.

Dysfunction or mutations in sodium-independent organic anion transporter genes can lead to various diseases, including:

* **Dubin-Johnson syndrome:** This inherited disorder is characterized by impaired bilirubin excretion, leading to jaundice and other liver problems.
* **Rotor syndrome:** This inherited disorder also affects bilirubin metabolism and excretion, but its symptoms are typically milder than those of Dubin-Johnson syndrome.
* **Drug-induced cholestasis:** Certain drugs can inhibit sodium-independent organic anion transporters, leading to impaired bile flow and cholestasis, a condition characterized by bile accumulation in the liver.

Overall, sodium-independent organic anion transport is a crucial process for maintaining homeostasis and eliminating various substances from the body. Its role in bile acid excretion, drug metabolism, hormone transport, and cellular detoxification makes it an essential component of normal physiological function.'

Acyclovir: A GUANOSINE analog that acts as an antimetabolite. Viruses are especially susceptible. Used especially against herpes.	2-aminopurines; oxopurine	antimetabolite; antiviral drug
rifampin	Rifampin: A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms.
