- Carbon monoxide counteracts one side-effect of an anti-cancer drug
11-21-2007 · EurekAlert!
Doxorubicin (DOX) is a red-colored anti-cancer drug that carries serious side effects for the heart. These cardio-toxic effects are due to inhibition by DOX of mitochondrial biogenesis, a term used to describe cellular energy generation. In a new study, it is now shown that mitochondrial biogenesis can be recovered in DOX-treated rodents by either inhalation of carbon monoxide or overexpression of the protein HO-1.

- Cicardian system suffers and protects from prenatal cocaine exposure
07-10-2007 · EurekAlert!
Researchers from Boston University School of Medicine have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadian hormone melatonin, can attenuate the prenatal effects of cocaine. These findings appear in the July 11 issue of the journal PLoS ONE.

- Prenatal nicotine exposure can lead to cardiac function reprogramming in adult offspring
05-01-2007 · EurekAlert!
New study using laboratory rats provides strong evidence that the effects of maternal smoking during the prenatal period of life can lead to cardiac vascular dysfunction beyond the formative years -- and into adulthood. What's more, the effect of nicotine shows a gender dichotomy with females being more susceptible than males.

- Prenatal exposure to glucocorticoids has long-term deleterious effects on newborns
03-22-2007 · EurekAlert!
Researchers at the University of Edinburgh, United Kingdom have found that, as for rodents and other nonprimates, prenatal exposure of nonhuman primate African vervet monkeys (Chloroceus aethiops) to glucocorticoids has long-lasting deleterious effects on cardiovascular, metabolic, and neuroendocrine function. These data suggest that both repeated glucocorticoid therapy and severe maternal stress late in gestation are likely to have long-term deleterious effects on developing human fetuses.

- Scientists uncover how hormones achieve their effects
10-22-2007 · EurekAlert!
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory. Similar signal chains are found in humans, where they are involved in many important processes such as the differentiation of nerve cells and the development of cancer. A sophisticated microscopy technique allowed the researchers to observe for the first time the interplay of signalling molecules in living yeast cells.

- Cocaine high caused by interference in neuronal receiving stations
12-06-2006 · EurekAlert!
Researchers have found evidence for a fundamental molecular mechanism underlying the hyperactive high of cocaine. In studies with rats, they have traced the effect to interactions between two types of receiving stations in neurons for nerve signals from their neighbors. The researchers' studies in rats found that when the animals received cocaine, a component of a receptor for the neurotransmitter dopamine tends to grab onto a component of a receptor for glutamate. The result, they found, was interference with normal activation of this glutamate receptor.

- Study finds reduced brain growth in alcoholics with family drinking history
02-21-2007 · EurekAlert!
Previous studies have shown that alcoholics have smaller brain volumes than non-alcoholics, an effect widely believed to be due to the toxic effects of ethanol. In this study, researchers found reduced brain growth among alcohol-dependent individuals with a family history of alcoholism or heavy drinking compared to those with no such family history. The finding demonstrates that reduced brain growth occurs among these individuals even before the onset of alcohol dependence.

- Ultra-low-dose aspirin might decrease bleeding severity in portal hypertension
10-09-2007 · EurekAlert!
A team led by Dr. Christian Doutremepuich from the University of Bordeaux 2 has determined that the paradoxical prothrombotic effects of ultra-low-dose aspirin, that could have beneficial properties decreasing bleeding complications of portal hypertension, are mediated by inhibition of Cyclooxygenase 2. This effect differs to the usual inhibition of Cyclooxygenase 1 at higher doses that has an antithrombotic action.

- Anemia treatment may be a double-edged sword
01-30-2008 · EurekAlert!
A study in February's Journal of Clinical Investigation finds that erythropoietin, commonly given for anemia, promotes blood-vessel growth in the eye, an effect that could either improve/worsen disease for patients with cancer, diabetic retinopathy, or retinopathy of prematurity. The effects on retinopathy depend on the timing of when erythropoietin is given.

- Carbon monoxide may cause long-lasting heart damage
01-29-2008 · EurekAlert!
Findings of a study by researchers at Rhode Island Hospital suggests that heart damage caused by carbon monoxide may have long-lasting effects even after the toxic gas has been eliminated from the blood.
