Removal of the transcription factor SAP1a member of the Ternary Complex Factor (TCF) group of transcription factors which in conjunction with Serum Response Factor (SRF) has been shown to have a profound effect on positive selection in the thymus. When another TCF Elk1 is knocked out in mice there i...

Prolonged cultivation of Saccharomyces cerevisiae in aerobic, glucose-limited chemostat cultures (dilution rate, 0·10 h–1) resulted in a progressive decrease of the residual glucose concentration (from 20 to 8 mg l–1 after 200 generations). This increase in the affinity for glucose was accompan...

Metabolic engineering to produce molecules not naturally synthesized by the host often requires directed evolution to improve pathway enzyme performance. Growth-coupled selection can dramatically increase directed-evolution throughput, and manipulation of redox balance has proven effective for tying...

During T cell development in the thymus, negative selection eliminates autoreactive and potentially harmful T cells, leading to central tolerance. This process, involves specific apoptosis programs thought to be governed by the transcription factor Nur77. To analyze the genetic pathways involved in ...
