Subsequent to microarray and real-time PCR data analysis, an evaluation of linear correlation was performed for a set of 25 genes (Table 5), and the statistical significance of the correlation was determined using One-way ANOVA in SPS software.
Microarray data of 903 neoplastic breast lesions, including 12 ER+ ADH, 22 ER+ DCIS, 68 ER+ IDC1, 189 ER+ IDC2, 273 ER+ IDC3, 44 ER− IDC2 and 299 ER− IDC3, were compared to microarray data of 255 normal breast tissues.
WWX contributed to microarray data analysis and performed single feature polymorphism analysis on microarray data.
To ensure that subsequent protein microarray data provided an accurate representation of the effect of EGCG and IL-1β on chondrocytes, nitrite levels were used as surrogate for NO expression induced by IL-1β and the effect of EGCG on NO expression to verify that the chondrocytes responded reproducibly to both the molecules.
To help ensure that subsequent microarray data provided an accurate representation of the effects of glucosamine and IL-1β on chondrocyte transcription, NO levels were used to verify that the cultures were viable and responded fully and reproducibly to both molecules [ 13, 22].
Subsequent microarray data, comparing primary mammary tumors to IGF-IR-independent recurrent tumors, has since identified members of the platelet-derived growth factor family (PDGF) as being upregulated during this process [ 14].
The spots corresponding to the double bands samples were flagged and eliminated in the subsequent microarray data analysis.
The influence of warm ex-vivo ischemia times, storage times, and biobanking protocols on RNA integrity and subsequent microarray data is not well documented.A prospective institutional review board-approved protocol for the banking of abdominal neoplasms was initiated at Memorial Sloan-Kettering Cancer Center in 2001.
Inaccurate gene structures derived from ab initio predictions misses or mispredicts genes resulting in errors in the annotations and subsequent microarray data.
While recent reports suggest that the magnitude of this bias may be relatively unimportant as long as the bias is highly reproducible [ 29], we feel that aggressively limiting any source of experimental bias improves the quality of subsequent microarray data.
