Behind the Scenes of Gene Expression

  pages={1064 - 1067}
As the units of DNA that define the proteins needed for life, genes have played biology9s center stage for decades. But work over the past few years shows that gene expression is not determined solely by the DNA code itself but by an assortment of proteins and, sometimes, RNAs that tell the genes when and where to turn on or off. Such epigenetic phenomena orchestrate the many changes through which a single fertilized egg cell turns into a complex organism. And throughout life, they enable cells…

Availability of the human genome sequence and those of other species is unmeasured in their value for a comprehensive understanding of the architecture, function and evolution of genomes and cells.

Proteins, the chaperone function and heredity

The evidence I here present of a crucial role for molecular chaperones in the folding of nascent proteins, as well as in DNA duplication, RNA folding and gene control, suggests that the family of proteins acting as molecular chapers provides information that is complementary to that stored in the nucleic acids, and equally important.

The Control of Expression of the α-Globin Gene Cluster

In this article, the research on the control of expression of the α-globin gene cluster is summarized with respect to the α—major regulatory element (α-MRE): HS-40, the tissue-specific and developmental control of its expression, and its chromosomal environment.

Epigenetics: Connecting Environment and Genotype to Phenotype and Disease

The challenge in oral biology will be to understand the mechanisms that modify MVPs in oral tissues and to identify those epigenetic patterns that modify disease pathogenesis or responses to therapy.

Epigenetics: A Challenge for Genetics, Evolution, and Development?

It is argued that differences in how one relates the genome to its surrounding contexts leads to diverse interpretations of the term epigenetics, and a paradigmatic shift has taken place in biology from the abandonment of a gene‐centric position on to the present.

Epigenetics and the Environment

It is proposed that DNA hypo‐ and hypermethylation are both important in the development of arsenic‐induced cancers, and heightened awareness by toxicologists of the importance of epigenetics in normal human development and in carcinogenesis should lead to the identification of other toxicants that manifest their effects via epigenetic mechanisms.

Oncogenomics: prospects for the future

Current and evolving genomic applications and the hypotheses underlying the modality for cancer therapy will be reviewed.

Epigenetics and Language: The Minimalist Program, Connectionism and Biology

It is agreed that inclusion of epigenetic processes in linguists' theories of language development is important if linguists desire unification with biology, and connectionism is the superior paradigm for researchers interested in unification between biology and linguistics.

Gene Technology in Tissue Engineering

This paper reviews research work of gene technology developed in tissue engineering and finds that plasmid DNA or genes encoding certain signaling factors can be expressed and secreted spatially and temporally by the transfected cells, which will promote the differentiation, proliferation and organization of the cells on the scaffold.
