A Cell Cycle Timer for Asymmetric Spindle Positioning
The displacement of the mitotic spindle to one side of a cell is important for many cells to divide unequally. While recent progress has begun to unveil some of the molecular mechanisms of mitotic spindle displacement, far less is known about how spindle displacement is precisely timed. A conserved mitotic progression mechanism is known to time events in dividing cells, although this has never ...
متن کاملCycle-Accurate Microarchitecture Performance Profiling
We present the design, implementation, and evaluation of a circuit we call the Statistics Module that captures cycle-accurate performance profiling at (or above) the microarchitecture layer. The circuit is deployed using an FPGA in the context of a soft-core characterization of a SPARC architecture (LEON). Accessible over the Internet, the circuit can be dynamically configured to capture progra...
متن کاملCycle-Accurate Microarchitecture Performance Evaluation
We present the design, implementation, and evaluation of a circuit we call the Statistics Module that captures cycle-accurate performance data at (or above) the microarchitecture layer. The circuit is deployed introspectively—in the architecture itself— using an FPGA in the context of a soft-core implementation of a SPARC architecture (LEON). Accessible over the Internet, the circuit can be dyn...
متن کاملAn Intracellular Timer in Oligodendrocyte Precursor Cells
Our interest in developmental timing began with a surprising experimental result obtained by Erika Abney, an immunologist who joined our group in the late 1970s. We had earlier defined a set of cell-type-specific markers that allowed us to distinguish the major types of glial cells found in suspensions and cultures of rat central nervous system (CNS) cells: astrocytes, which are heterogeneous a...
متن کاملCell Timer/Cell Clock
Like the biological clock in the body, replication of each cell type (even different cells of the same organism) follows a timing program. Abnormal function of this timer could be an alarm for a disease like cancer. DNA replication starts from a specific point on the chromosome that is called the origin of replication. In contrast to prokaryotes in which DNA replication starts from a single ...
