[Q]: To study the mechanism of centrosome duplication in cycling cells, we established a novel system of multiple centrosome formation in two types of cells: CHO cells treated with RO3306, a Cyclin-dependent kinase 1 (Cdk1) inhibitor and DT40 cells, in which Cdks were knocked out by chemical genetics. Cdk1-inactivated cells initiated DNA replication and centrosome duplication at the onset of S phase. They became arrested at the end of G2, but the centrosome cycle continued to produce supernumerary centrioles/centrosomes without DNA endoreplication in those cells. Centrosomes were amplified in a highly synchronous and reproducible manner: all of them were located next to the nucleus and spread widely apart from each other with several m in distance. Double knockout of Cdk1 and Cdk2 caused cell cycle arrest at G1/S and centrosomes were no longer duplicated. However, cells continued to grow and increased their volume over 10-fold during 48 hr of culture. Centrosome components, including -tubulin and Cep135, were synthesized and accumulated during the arrest, allowing rapid centrosome multiplication upon recovery from the cell cycle arrest or expression of exogenous Plk4 in G1/S cells. Thus centrosome amplification results from the discoordination of the centrosome cycle from the progression of other cell cycle events, which is controlled by different levels of Cdk activities.
[A]: Where in the cell do we find the protein Cep135?

[Q]: TransLink is urging customers to avoid non-essential travel today and to stay home where possible in the difficult weather conditions. TransLink chief executive officer Peter Strachan said bus and train services were continuing to run where possible, however all CityCat and CityFerry services had been cancelled until further notice. "These are extremely difficult conditions for South East Queensland---we are running essential services where possible but safety remains to be the most important," Mr Strachan said. "Severe weather and associated flooding has impacted on all modes of public transport, with bus, ferry and train services all impacted to varying degrees. "If you are planning to use public transport at anytime over the next few days, then I would recommend you check that your intended service is still running." Service disruptions for today include: l City network trains running hourly on all lines. l Bus diversions, delays and cancellations in some regions, particularly across Brisbane, Ipswich and the Sunshine Coast. l CityCat and CityFerry services cancelled. Queensland Rail Chief Executive Officer Paul Scurrah said rising waterways had closed some train lines, and road closures and damage to property throughout the South-East had contributed to a shortage of available rail employees. "We intend to run trains hourly on all lines, similar to the timetable we operate on Christmas Day. We will also be looking to run other additional services to meet demand as required. At this stage we will run services stopping at all stations which will depart at the same time on the hour, however, this is all subject to the weather conditions and the availability of traincrew." Mr Scurrah encouraged all customers to visit the Translink website for specific departure times for their station, and asked for patience in the event of delays. "Queensland Rail appreciates that reduced services may cause disruptions but it is simply unavoidable. We have a dedicated and experienced team monitoring the situation around the clock and will be working to reopen the network as soon as practicably possible," Mr Scurrah said. The latest service disruption information is available on the TransLink website www.translink.com.au.
