REtr causes genomic instability in human CD34+ cells. Activated forms of c-KIT, like c-KIT(N822K), rescue the REtr-induced genomic instability by increasing the rate of DNA repair by homologous recombination. Human CD34+ hematopoietic progenitor cells were transduced with retroviral vectors encoding...

Plant hypocotyls elongate in response to darkness. The response to darkness is gated by the circadian clock, such that wild-type plants (Col) only respond to darkness with growth once every 24 hours, whereas arrhythmic lines, such as CCA1-34, will respond to darkness with growth at any time of day....

In plants, drought stress is a major growth limiting factor causing cell water loss through open stomata. In this study, guard cell-specific transcripts from drought-stressed Arabidopsis plants were analyzed and a down-regulation of β-amylase 1 (BAM1) was found. In previous studies, BAM1 was shown t...

Background: Infrared A radiation (IRA 760-1440 nm) is a major component of solar radiation and, similar to ultraviolet (UV) radiation, causes photoaging of human skin by increasing the expression of matrixmetalloproteinase-1 (MMP-1) expression in human skin fibroblasts. This gene-regulatory effect ...
