A novel transcription factor Sdr1 involving sulfur depletion response in fission yeast.

In the fission yeast Schizosaccharomyces pombe, the response to sulfur depletion has been less studied compared to the response to nitrogen depletion. Our study reveals that the fission yeast gene, SPCC417.09c, plays a significant role in the sulfur depletion response.

Development of Human CBF1-Targeting Single-Stranded DNA Aptamers with Antiangiogenic Activity .

C promoter binding factor 1 (CBF1) (alias RBPJ) is a critical transcription factor involved in Notch signaling. The activation of Notch signaling through CBF1 maintains the angiostatic state of endothelial cells suppressing angiogenesis, that is, the formation of new blood vessels. Vascular endothelial growth factor (VEGF) induces angiogenesis by promoting the proteasomal degradation of CBF1, in addition to endothelial cell proliferation.
