| Dr. Subhash Pandey is a nationally and internationally well-known neuroscientist in the alcohol addiction field and has contributed significantly towards a better understanding of the neurobiology of alcoholism. Two striking features of alcohol addiction are the rapid onset of tolerance to the acute effects of alcohol and the development of ethanol withdrawal symptoms after cessation of protracted ethanol consumption. Predisposition to alcohol abuse may also involve abnormalities in the signaling cascade pathways that ultimately lead to abnormal gene transcription patterns in the specific neural circuitry of the brain. The long-term goal of Dr. Pandey's alcohol research program is to elucidate the molecular and cellular mechanisms (cAMP responsive element binding protein (CREB) gene transcription factor and CREB-related genes) involved in anxiety, alcohol dependence and/or alcohol drinking behaviors so as to eventually provide a basis for designing drugs to treat alcohol abuse and anxiety disorders. Changes in CREB function may also lead to changes in synaptic structures, such as dendritic spines in the brain, during ethanol exposure and its withdrawal. Dr. Pandey's lab has also involved in investigating the epigenetic mechanisms (chromatin remodeling) of anxiety and alcohol addiction. An additional area of Dr. Pandey's interest is to identify the molecular and cellular mechanisms that are operative in the interactions between ethanol and nicotine. It is possible that alcohol and nicotine may share common molecular mechanisms in common neurocircuitry involved in producing behaviors related to co-abuse of smoking and drinking. Some of his work has been highlighted by National Institutes of Health:
