Transcription factor IIE (TFIIE) is a general initiation and promoter escape factor for RNA polymerase II composed of p56 (TFIIE-alpha) and p34 (TFIIE-beta) subunits. Our laboratories experienced difficulty producing adequate quantities of recombinant human TFIIE-alpha for in vitro studies using available clones. We therefore re-engineered the TFIIE subunit production vectors and tested various...
Progression of retinal degeneration in a mouse model was studied in vivo with high-resolution spectral-domain optical coherence tomography (SD-OCT). Imaging in 3D with high depth resolution (<3 mum), SD-OCT resolved all the major layers of the retina of control C57BL/6J mice. Images of transgenic mice having a null mutation of the rhodopsin gene revealed the anatomical consequences of retinal d...
The effect of quercetin, a flavonoid found in many plants, on the proliferation of human leukemic T-cells was analyzed. Quercetin reversibly blocked the cell cycle at a point 3-6 h before the start of DNA synthesis. Expression of the growth-related genes histone H4, cyclin A and B, and p34 ~dc2 was suppressed in cells blocked with quercetin. Comparison of the quercetin arrest points with those ...
