Though there are multiple routes through which parents can influence their offspring, recent studies of environmentally induced epigenetic variation have highlighted the role of non-genomic pathways. In addition to the experience-dependent modification of DNA methylation that can be achieved via mother-infant interactions, there has been increasing interest in the epigenetic mechanisms through ...

BACKGROUND It has been reported that children with parental drinking problems are at increased risk of drinking problems or psychiatric diseases in adulthood. The present study was conducted to examine the psychiatric characteristics of high school students according to paternal drinking problems. METHODS The subjects were 950 high school students (390 male and 560 female). The paternal drink...

Leukocyte telomere length (LTL) is longer in association with advanced paternal age, but this association has not been examined along with family history (FH) in schizophrenia. LTL was measured by PCR and compared across cases and controls as part of a study to examine the characteristics of paternal age related schizophrenia. The 53 schizophrenia cases had similar mean LTL as 20 controls, alth...

Global demethylation of DNA which marks the onset of development occurs asynchronously in the mouse; paternal DNA is demethylated at the the zygote stage, whereas maternal DNA is demethylated later in development. The biological function of such asymmetry and its underlying mechanisms are currently unknown. To test the hypothesis that the early demethylation of male DNA may be associated with p...

There is a risk that ICSI may increase the transmission of mtDNA diseases to children born after this technique. Knowledge of the fate and transmission of paternal mitochondrial DNA is important since mutations in mitochondrial DNA have been described in oligozoospermic males. We have used an adaptation of solid phase mini-sequencing to exclude the presence of levels of paternal mtDNA >0.001% i...

OBJECTIVE To investigate whether advanced paternal age is associated with increased psychotic-like experiences (PLEs) and increased sensitivity to Cannabis in the offspring. METHODS A cross-sectional population-based study in 1684 participants aged 18 to 25. RESULTS We found no association of paternal age with PLEs. Only the positive dimension subscale was associated to paternal age, but th...

The authors examined the relationship between maternal depression, paternal psychopathology, and adolescent diagnostic outcomes in a community sample of 522 Australian families. They also examined whether chronic family stress, father's expressed emotion, and parents' marital satisfaction mediated the relationship between parental psychopathology and adolescent outcomes. Mother's education, chi...

I describe an agent-based model to study the evolution of paternal care. The reported n-person Iterated Prisoner’s Dilemma shows that the relative differences in the reproductive effort between sexes can explain the evolution of paternal care. When female reproductive costs are higher than male reproductive costs, males cooperate with females even when females do not reciprocate. Paternal care ...

This study examined the mediating role of coparenting in the association between differences/similarities in paternal and maternal socioeconomic status (SES) and paternal involvement in Chinese families. The sample included 244 couples with children aged 3-7 years. Fathers and mothers reported their individual incomes, educational levels, occupations, and coparenting behavior (measured using th...

The possibility of incomplete maternal transmission of mitochondrial DNA (mtDNA) in Drosophila, previously suggested by the presence of heteroplasmy, was examined by intra- and interspecific backcrosses of Drosophila simulans and its closest relative, Drosophila mauritiana. mtDNAs of offspring in these crosses were characterized by Southern hybridization with two alpha-32P-labeled probes that a...
