Enhanced Nicotine Self-Administration And Suppressed Dopaminergic Systems In A Rat Model Of Diabetes, Laura O'Dell Aug 2013

Enhanced Nicotine Self-Administration And Suppressed Dopaminergic Systems In A Rat Model Of Diabetes, Laura O'Dell

Departmental Papers (Psych)

Patients with diabetes display a heightened propensity to use tobacco; however, it is unclear whether they experience enhanced rewarding effects of nicotine. Thus, this study examined the reinforcing effects of nicotine in a rodent model of diabetes involving administration of streptozotocin (STZ), a drug that is toxic to pancreatic insulin-producing cells. The first study compared STZ- and vehicle-treated rats that had 23-hour access to intravenous self-administration (IVSA) of nicotine or saline and concomitant access to food and water. In order to examine the contribution of dopamine to our behavioral effects, dopamine transporter (DAT), D1 and D2 receptor levels were compared …


A Mechanistic Hypothesis Of The Factors That Enhance Vulnerability To Nicotine Use In Females, Laura O'Dell Jun 2013

A Mechanistic Hypothesis Of The Factors That Enhance Vulnerability To Nicotine Use In Females, Laura O'Dell

Departmental Papers (Psych)

Women are particularly more vulnerable to tobacco use than men. This review proposes a unifying hypothesis that females experience greater rewarding effects of nicotine and more intense stress produced by withdrawal than males. We also provide a neural framework whereby estrogen promotes greater rewarding effects of nicotine in females via enhanced dopamine release in the nucleus accumbens (NAcc). During withdrawal, we suggest that corticotropin-releasing factor (CRF) stress systems are sensitized and promote a greater suppression of dopamine release in the NAcc of females versus males. Taken together, females display enhanced nicotine reward via estrogen and amplified effects of withdrawal via …


Behavioral, Biochemical, And Molecular Indices Of Stress Are Enhanced In Female Versus Male Rats Experiencing Nicotine Withdrawal, Laura O'Dell May 2013

Behavioral, Biochemical, And Molecular Indices Of Stress Are Enhanced In Female Versus Male Rats Experiencing Nicotine Withdrawal, Laura O'Dell

Departmental Papers (Psych)

Stress is a major factor that promotes tobacco use and relapse during withdrawal. Although women are more vulnerable to tobacco use than men, the manner in which stress contributes to tobacco use in women versus men is unclear.Thus, the goal of this study was to compare behavioral and biological indices of stress in male and female rats during nicotine withdrawal. Since the effects of nicotine withdrawal are age-dependent, this study also included adolescent rats. An initial study was conducted to provide comparable nicotine doses across age and sex during nicotine exposure and withdrawal. Rats received sham surgery or an osmotic …
