Application

Cocaine hydrochloride has been used:
  • in saline control to study the effects of cocaine self-administration in mouse brain
  • as adopamine (DA), noradrenaline (NA), and serotonin (5-HT) reuptake inhibitor to evoke neurotransmitter release in artificial fish cerebrospinal fluid (aCSF)
  • to examine conditioning to intravenous cocaine hydrochloride

Biochem/physiol Actions

Inhibits the dopamine, norepinephrine, and serotonin transporters with Kis of about 300 nM, 900 nM, and 400 nM, respectively. Unlike amphetamines, it has no effect on catecholamine release.

We previously showed that the transcription factor Egr3 (early growth response 3) is oppositely regulated in nucleus accumbens (NAc) cell subtypes 24 hours following cocaine exposure and bidirectionally mediates cocaine-related behaviors in male rodents. Overexpressing Egr3 in D2 receptor-containing medium

Cocaine addiction remains a major public concern throughout the world especially in developed countries. In the last three decades, significant achievements have led to a greater understanding of the signaling pathways involved in the development of cocaine addiction; however, there

Cocaine addiction is a chronic and relapsing disorder with an important genetic component. Human candidate gene association studies showed that the single nucleotide polymorphism (SNP) rs16969968 in the α5 subunit (α5SNP) of nicotinic acetylcholine receptors (nAChRs), previously associated with increased

MicroRNA-124 (miR-124), a brain-enriched microRNA, is known to regulate microglial quiescence. Psychostimulants such as cocaine have been shown to activate microglia by downregulating miR-124, leading, in turn, to neuroinflammation. We thus rationalized that restoring the levels of miR-124 could function

High-frequency intake and high drug-induced seeking are associated with cocaine addiction in both human and animals. However, their relationships and neurobiological underpinnings remain hypothetical. The medial prefrontal cortex (mPFC), basolateral amygdala (BLA), and nucleus accumbens (NAc) have been shown to
