    Insights

    Paternal exposure to opioids like morphine and agents such as nitrous oxide can cause developmental delays and behavioral changes in offspring across multiple generations.

    Area of Science:

    • Toxicology
    • Developmental Biology
    • Reproductive Science

    Background:

    • Paternal exposure to xenobiotics may impact offspring development.
    • Opioids and anesthetic gases are common environmental exposures.

    Purpose of the Study:

    • Investigate postnatal functional effects of paternal opioid and xenobiotic exposure.
    • Assess multi-generational impacts on offspring development and behavior.

    Main Methods:

    • Male mice exposed to morphine, levorphanol, dextrorphan, or nitrous oxide.
    • Offspring reproductive indices, endocrine parameters, and behavior assessed.
    • Multi-generational effects studied through selective inbreeding.

    Main Results:

    • Paternal exposure caused developmental delays and altered maturational indices in offspring across generations.
    • Morphine offspring showed attenuated luteinizing hormone response and learning deficits.
    • Levorphanol, dextrorphan, and nitrous oxide offspring exhibited behavioral and physiological alterations.

    Conclusions:

    • Paternal exposure to opioids and nitrous oxide induces lasting functional sequelae in offspring.
    • These findings highlight the transgenerational risks of environmental toxicant exposure.

    X-linked Traits01:19

    X-linked Traits

    In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.
    Sex-linked Disorders01:43

    Sex-linked Disorders

    Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
    Genomic Imprinting and Inheritance02:30

    Genomic Imprinting and Inheritance

    Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
    The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
    Dosage Compensation02:50

    Dosage Compensation

    In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
    In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with  distinct numbers of X chromosomes will have...
    Teratogenicity01:07

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
    Toxicity Testing in Animals01:23

    Toxicity Testing in Animals

    Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
