Expanding The Temporal Dimensions Of Developmental Biology: The Role Of Environmental Agents In Establishing Adult-Onset Phenotypes, Scott F. Gilbert Dec 2011

Expanding The Temporal Dimensions Of Developmental Biology: The Role Of Environmental Agents In Establishing Adult-Onset Phenotypes, Scott F. Gilbert

Biology Faculty Works

Developmental biology is expanding into several new areas. One new area of study concerns the production of adult-onset phenotypes by exposure of the fetus or neonate to environmental agents. These agents include maternal nutrients, developmental modulators (endocrine disruptors), and maternal care. In all three cases, a major mechanism for the generation of the altered phenotype is chromatin modification. Nutrient conditions, developmental modulators, and even maternal care appear to alter DNA methylation and other associated changes in chromatin that regulate gene expression. This brings a new, under-appreciated, dimension of gene regulation into developmental biology, and it also demonstrates the poverty of …


Fertilization Narratives In The Art Of Gustav Klimt, Diego Rivera And Frida Kahlo: Repression, Domination And Eros Among Cells, Scott F. Gilbert, S. Brauckmann Jun 2011

Fertilization Narratives In The Art Of Gustav Klimt, Diego Rivera And Frida Kahlo: Repression, Domination And Eros Among Cells, Scott F. Gilbert, S. Brauckmann

Fertilization narratives are powerful biological stories that can be used for social ends, and 20th-century artists have used fertilization-based imagery to convey political and social ideas. In Danae, Gustav Klimt used an esoteric stage of early human embryos to indicate successful fertilization and the inability of government repression to stifle creativity. In Man, Controller of the Universe, Diego Rivera painted a mural of a man controlling an ovulating ovary, depicting Trotsky's view that society will rationally regulate human fertilization. His former wife, Frida Kahlo, refuted this view in Moses: Nucleus of Creation, wherein she painted images of fertilization and embryo …
