Cell cycle: Cull and destroy

Cell cycle: Cull and destroy

A newly discovered family of proteins homologous to yeast Cdc53, called cullins, may play a key role in the targeting of cell-cycle regulators, such as cyclins, for destruction by ubiquitin-dependent proteolysis.

Cell cycle and apoptosis: A review

Cancer is characterized by abnormally excessive cell proliferation. Cell proliferation, the process by which a cell grows and divides to produce two daughter cells. Each of these daughter cells divides to produce two new cells, steps that are called cell cycle. Meanwhile, apoptosis is a highly regulated process of cell death, which is involved not only in the development of shape and morphogene...

Cull Cow Finishing Performance

Destroy and localize

itotic spindle positioning involves a con-formational switch in LGN, the mammalian version of the invertebrate Pins protein, duces a spindle rocking that represents the first genetically manipulable model for studying spindle positioning in vertebrates. The switch operates via the opening of LGN, which can normally fold back onto itself. The unfolding is triggered by binding to either membrane-...

Marketing and Feeding Cull Cows

Cull cows often are overlooked as a source of income to the cow-calf enterprise. Depending upon the relationships between cull cow and calf prices, and the herd culling rate, cull cow receipts generally account for 15 to 30 percent of cash receipts from the cow-calf enterprise. However, some producers give little attention to this source of income and ways of enhancing it. For many producers, c...
