Epidemiology Of Moderate Alcohol Consumption And Breast Cancer: Association Or Causation?, Samir Zakhari, Jan B. Hoek
Epidemiology Of Moderate Alcohol Consumption And Breast Cancer: Association Or Causation?, Samir Zakhari, Jan B. Hoek

Epidemiological studies have been used to show associations between modifiable lifestyle habits and the incidence of breast cancer. Among such factors, a history of alcohol use has been reported in multiple studies and meta-analyses over the past decades. However, associative epidemiological studies that were interpreted as evidence that even moderate alcohol consumption increases breast cancer incidence have been controversial. In this review, we consider the literature on the relationship between moderate or heavy alcohol use, both in possible biological mechanisms and in variations in susceptibility due to genetic or epigenetic factors. We argue that there is a need to incorporate …

While it is clear that behavioral experience modulates epigenetic profiles, it is less evident how the nature of that experience influences outcomes and whether epigenetic/genetic "biomarkers" could be extracted to classify different types of behavioral experience. To begin to address this question, male and female mice were subjected to either a Fixed Interval (FI) schedule of food reward, or a single episode of forced swim followed by restraint stress, or no explicit behavioral experience after which global expression levels of two activating (H3K9ac and H3K4me3) and two repressive (H3K9me2 and H3k27me3) post-translational histone modifications (PTHMs), were measured in hippocampus (HIPP) …
Sex-Dependent Effects Of Developmental Lead Exposure On The Brain, Garima Singh, Vikrant Singh, Marissa Sobolewski, Deborah A. Cory-Slechta, Jay S. Schneider
Sex-Dependent Effects Of Developmental Lead Exposure On The Brain, Garima Singh, Vikrant Singh, Marissa Sobolewski, Deborah A. Cory-Slechta, Jay S. Schneider

The role of sex as an effect modifier of developmental lead (Pb) exposure has until recently received little attention. Lead exposure in early life can affect brain development with persisting influences on cognitive and behavioral functioning, as well as, elevated risks for developing a variety of diseases and disorders in later life. Although both sexes are affected by Pb exposure, the incidence, manifestation, and severity of outcomes appears to differ in males and females. Results from epidemiologic and animal studies indicate significant effect modification by sex, however, the results are not consistent across studies. Unfortunately, only a limited number of …
