Project description:A zebra mussel byssus cDNA microarray was used to identify the differentially expressed genes between attachment and detachment. Keywords: Gene differential expression The zebra mussels were divided in to two groups: AT and DT. In group AT all the zebra mussels were kept in the water attached for 48 hours while in group DT, the individuals were kept detached underwater for 48 hours. The feet of the zebra mussels were taken from each group. Four replicates, including four individual feet each replicate, were taken from each group for total RNA extraction. Four microarray hybridization performed between AT and DE. In each group, two cDNA replicates were labeled with Alexa 555 while the other two were labeled with Alexa 647. Every hybridization happened between two cDNA samples from different group with different labels.
Project description:To identify the expression profiles of zebra mussel byssus unique genes with the regeneration of the byssal threads, a time-course study was performed. The RNA samples from the feet of fully attached zebra mussels (maintained attachment for more than 4 weeks) were extracted as common reference. The detached mussels were allowed to re-attach on underwater surface. Then the RNA samples from feet of the mussels at different time points post detachment were taken, namely, 12 hours, 1 day, 2 days, 3 days, 4 days, 7 days, and 21 days post detachment. The comparisons of the genes expression profiles were made between different time points and reference, as well as the any two connected time points (expect for 7 days and 21 days).

The dual-channel microarray hybridizations were performed as following: 12hâR, 12hâR, 1DâR, 1DâR, 2DâR, 2DâR, 3DâR, 3DâR, 4DâR 4DâR, 7DâR, 7DâR, 21DâR, 21DâR, 12hâ1D, 12hâ1D, 1Dâ2D, 1Dâ2D, 2Dâ3D, 2Dâ3D, 3Dâ4D, 3Dâ4D, 4Dâ7D, 4Dâ7D, 7Dâ21D, 7Dâ21D. The direction of the arrows stand for the way of labeling: Alexa555âAlexa647. Six biological replicates of 1D, 2D, 3D, 4D, and 7D were used; four biological repllicates of 12h and 21D were taken; fourteen biological replicates of reference were applied. The whole experiment includes 26 microarray slide hybridizations.
Project description:Factorial Microarray Analysis of Zebra Mussel (Dreissena polymorpha) Adhesion Process under the Impact of Multiple Environmental Factors The expression profiles of the zebra mussel byssus unique genes in our cDNA microarray can be influenced by multiple factors. Three environmental factors plus adhesion status were considered as four main factors in this study.
