Runx proteins regulate Foxp3 expression.

17 Oct 2009 Runx proteins are essential for hematopoiesis and play an important role in T cell development by regulating key target genes, such as CD4 and CD8 as well as lymphokine genes, during the specialization of naive CD4 T cells into distinct T helper ... Read more...

miR-449a and miR-449b are direct transcriptional targets of E2F1 and negatively regulate pRb-E2F1 activity through a feedback loop by targeting CDK6 and CDC25A.

13 Oct 2009 The Rb-E2F pathway drives cell cycle progression and cell proliferation, and the molecular strategies safeguarding its activity are not fully understood. Here we report that E2F1 directly transactivates miR-449a/b. miR-449a/b targets and inhibits ... Read more...

Comment on "The Arabidopsis circadian clock incorporates a cADPR-based feedback loop".

7 Oct 2009 Dodd et al. (Reports, 14 December 2007, p. 1789) reported that the Arabidopsis circadian clock incorporates the signaling molecule cyclic adenosine diphosphate ribose (cADPR). In contrast, we found that there is no rhythm of cADPR levels nor are ... Read more...

Technical information about 'Feedback, Biochemical'

Definition: A mechanism of communication among life processes to coordinate development, reproduction, and homeostasis. In humans, feedback loops are especially important for communication between organs that are spatially separated. Virtually all hormones from the nervous and endocrine systems are under feedback control: by peripheral hormones, cations, metabolites, osmolarity or extracellular fluid volume.
