Shoot meristems: Intercellular signals keep the balance
Recent studies have identified a complex intercellular communication network which maintains the balance of indeterminate and determinate cells at the plant apical meristem. The widespread presence of homologous regulatory genes indicates that 'stemness' arose before the evolutionary split between plants and animals.
متن کاملX chromosome dosage compensation: how mammals keep the balance.
The development of genetic sex determination and cytologically distinct sex chromosomes leads to the potential problem of gene dosage imbalances between autosomes and sex chromosomes and also between males and females. To circumvent these imbalances, mammals have developed an elaborate system of dosage compensation that includes both upregulation and repression of the X chromosome. Recent advan...
متن کاملPostural strategy to keep balance on the seesaw.
This work investigates the kinematic and electromyography (EMG) strategy used by the central nervous system (CNS) to keep equilibrium during anterior-posterior balance on seesaws with different degrees of instability. The movement of hip, knee, and ankle were reconstructed using a 3D motion-analysis system and the EMG activities of selected ankle, knee, and hip muscles were recorded. Balance wa...
متن کاملKeep-ING balance: tumor suppression by epigenetic regulation.
Cancer cells accumulate genetic and epigenetic changes that alter gene expression to drive tumorigenesis. Epigenetic silencing of tumor suppressor, cell cycle, differentiation and DNA repair genes contributes to neoplastic transformation. The ING (inhibitor of growth) proteins (ING1-ING5) have emerged as a versatile family of growth regulators, phospholipid effectors, histone mark sensors and c...
متن کاملThe Keep Emulation Framework
As part of the overall KEEP Project the task of the Emulation Framework (EF) is to provide the emulation environments required for this purpose. In a very simple and comprehensible way the users can employ emulations for the representation and the performance of both digital objects in obsolete data formats and applications for antiquated computer systems. The virtual reconstruction of original...
