Stress and cocaine interact to modulate Arc/Arg3.1 expression in rat brain

Rationale The interaction between stress and drugs of abuse is a critical component of drug addiction, but the underlying molecular mechanisms remain elusive. Arc/Arg3.1 is an effector immediate early gene that may represent a bridge connecting short- and long-term neuronal modifications associated...

520			\|a Rationale The interaction between stress and drugs of abuse is a critical component of drug addiction, but the underlying molecular mechanisms remain elusive. Arc/Arg3.1 is an effector immediate early gene that may represent a bridge connecting short- and long-term neuronal modifications associated with exposure to stress and drugs of abuse. Objectives This research aims to study the modulation of Arc/Arg3.1 expression as a marker of neuronal changes associated with exposure to stress and cocaine. Materials and methods Rats exposed to either single or repeated stress sessions were subjected to a single intraperitoneal injection of cocaine hydrochloride (10 mg/kg) and sacrificed 2 h later. RNase protection assay was used to determine changes in Arc/Arg3.1 gene expression in different brain regions. Results We found significant stress–cocaine interactions in the prefrontal cortex (p < 0.001) and hypothalamus (p < 0.05). In the prefrontal cortex, acute stress potentiated cocaine-induced Arc/Arg3.1 mRNA elevation, whereas prolonged stress attenuated the response to cocaine. In the hypothalamus, although markedly reduced by acute stress, Arc/Arg3.1 gene expression was still increased by cocaine. No interaction was observed following repeated stress. Notably, cocaine-induced Arc/Arg3.1 mRNA levels were not influenced by stress in striatum and hippocampus. Conclusions In our experimental model, stress interacted with cocaine to alter Arc/Arg3.1 expression in a regionally selective fashion and in a way that depended on whether stress was acute or repeated. These results point to Arc/Arg3.1 as a potential molecular target modulated by stress to alter cellular sensitivity to cocaine.

Arc/Arg3.1 is an effector immediate early gene that may represent a bridge connecting short- and long-term neuronal modifications associated with exposure to stress and drugs of abuse. Objectives This research aims to study the modulation of Arc/Arg3.1 expression as a marker of neuronal changes associated with exposure to stress and cocaine. Materials and methods Rats exposed to either single or repeated stress sessions were subjected to a single intraperitoneal injection of cocaine hydrochloride (10 mg/kg) and sacrificed 2 h later. RNase protection assay was used to determine changes in Arc/Arg3.1 gene expression in different brain regions. Results We found significant stress–cocaine interactions in the prefrontal cortex (p < 0.001) and hypothalamus (p < 0.05). In the prefrontal cortex, acute stress potentiated cocaine-induced Arc/Arg3.1 mRNA elevation, whereas prolonged stress attenuated the response to cocaine. In the hypothalamus, although markedly reduced by acute stress, Arc/Arg3.1 gene expression was still increased by cocaine. No interaction was observed following repeated stress. Notably, cocaine-induced Arc/Arg3.1 mRNA levels were not influenced by stress in striatum and hippocampus. Conclusions In our experimental model, stress interacted with cocaine to alter Arc/Arg3.1 expression in a regionally selective fashion and in a way that depended on whether stress was acute or repeated. These results point to Arc/Arg3.1 as a potential molecular target modulated by stress to alter cellular sensitivity to cocaine.

Arc/Arg3.1 is an effector immediate early gene that may represent a bridge connecting short- and long-term neuronal modifications associated with exposure to stress and drugs of abuse. Objectives This research aims to study the modulation of Arc/Arg3.1 expression as a marker of neuronal changes associated with exposure to stress and cocaine. Materials and methods Rats exposed to either single or repeated stress sessions were subjected to a single intraperitoneal injection of cocaine hydrochloride (10 mg/kg) and sacrificed 2 h later. RNase protection assay was used to determine changes in Arc/Arg3.1 gene expression in different brain regions. Results We found significant stress–cocaine interactions in the prefrontal cortex (p < 0.001) and hypothalamus (p < 0.05). In the prefrontal cortex, acute stress potentiated cocaine-induced Arc/Arg3.1 mRNA elevation, whereas prolonged stress attenuated the response to cocaine. In the hypothalamus, although markedly reduced by acute stress, Arc/Arg3.1 gene expression was still increased by cocaine. No interaction was observed following repeated stress. Notably, cocaine-induced Arc/Arg3.1 mRNA levels were not influenced by stress in striatum and hippocampus. Conclusions In our experimental model, stress interacted with cocaine to alter Arc/Arg3.1 expression in a regionally selective fashion and in a way that depended on whether stress was acute or repeated. These results point to Arc/Arg3.1 as a potential molecular target modulated by stress to alter cellular sensitivity to cocaine.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Psychostimulants</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Immediate early genes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Prefrontal cortex</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Drug abuse</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Racagni, Giorgio</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fumagalli, Fabio</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Psychopharmacology</subfield><subfield code="d">Berlin : Springer, 1959</subfield><subfield code="g">218(2011), 1 vom: 18.

abstract	Rationale The interaction between stress and drugs of abuse is a critical component of drug addiction, but the underlying molecular mechanisms remain elusive. Arc/Arg3.1 is an effector immediate early gene that may represent a bridge connecting short- and long-term neuronal modifications associated with exposure to stress and drugs of abuse. Objectives This research aims to study the modulation of Arc/Arg3.1 expression as a marker of neuronal changes associated with exposure to stress and cocaine. Materials and methods Rats exposed to either single or repeated stress sessions were subjected to a single intraperitoneal injection of cocaine hydrochloride (10 mg/kg) and sacrificed 2 h later. RNase protection assay was used to determine changes in Arc/Arg3.1 gene expression in different brain regions. Results We found significant stress–cocaine interactions in the prefrontal cortex (p < 0.001) and hypothalamus (p < 0.05). In the prefrontal cortex, acute stress potentiated cocaine-induced Arc/Arg3.1 mRNA elevation, whereas prolonged stress attenuated the response to cocaine. In the hypothalamus, although markedly reduced by acute stress, Arc/Arg3.1 gene expression was still increased by cocaine. No interaction was observed following repeated stress. Notably, cocaine-induced Arc/Arg3.1 mRNA levels were not influenced by stress in striatum and hippocampus. Conclusions In our experimental model, stress interacted with cocaine to alter Arc/Arg3.1 expression in a regionally selective fashion and in a way that depended on whether stress was acute or repeated. These results point to Arc/Arg3.1 as a potential molecular target modulated by stress to alter cellular sensitivity to cocaine. © Springer-Verlag 2011
