In the absence of Slimb, each mother centrosome can give rise to several daughters in one go, ... produced several important findings relating to centrosome control: they identified another molecule, SAK, ...

Hopkins researchers piece together gene 'network' linked to schizophrenia

... of proteins had discovered that one of them, BBS4, also is found near the centrosome and also binds to PCM1. "But we weren't thinking schizophrenia at the time ... The researchers then asked if the failure of PCM1 recruitment to the centrosome in mice lacking either DISC1 or BBS4 affects brain development. To do ...

The cooperative view: New evidence suggests a symbiogenetic origin for the centrosome

Double trouble: Cells with duplicate genomes can trigger tumors

... called Barrett's esophagus. In addition to the extra chromosomes, the "double value" or "tetraploid" cells also duplicate a cell structure called the centrosome that plays a role in maintaining a stable genome. The extra centrosomes may be at the root of the cancer-triggering process. Once the genetic ...
