The noncoding genome: implications for ruminant reproductive biology

The Drosophila genome sequence: implications for biology and medicine.

The 120-megabase euchromatic portion of the Drosophila melanogaster genome has been sequenced. Because the genome is compact and many genetic tools are available, and because fly cell biology and development have much in common with mammals, this sequence may be the Rosetta stone for deciphering the human genome.

The completed human genome: implications for chemical biology.

The recently completed human genome sequence represents an enormous opportunity to understand biology and accelerate the development of new therapeutics. However, it also presents equally large logistical, scientific and paradigmatic challenges to efficiently translate the enormous cache of sequence data into functional information that will be the precursor of new drug development. Small-molec...

The genome sequence of taurine cattle: a window to ruminant biology and evolution.

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes hav...

Very Small Embryonic-Like Stem Cells: Implications in Reproductive Biology

The most primitive germ cells in adult mammalian testis are the spermatogonial stem cells (SSCs) whereas primordial follicles (PFs) are considered the fundamental functional unit in ovary. However, this central dogma has recently been modified with the identification of a novel population of very small embryonic-like stem cells (VSELs) in the adult mammalian gonads. These stem cells are more pr...
