In particular, the Chihuahua samples matched DNA samples previously published from pre-Columbian Mexican fossil dogs, confirming that the diminutive breed has a Mexican origin.
In the current study, we performed an integrated data analysis, combining gene expression profiles from our collected paired stage II CRC patient's samples, with genomic alteration data of 195 CRC samples, previously published by the Cancer Genome Atlas (TCGA) project, along with extracted results from more than 50 previously published microarray studies.
Each sample (previously published and present) has its own representative model reflecting factor structure.
However, in comparing standard demographic and clinical characteristics, including age, gender, race, employment status, duration of pDPN, pain severity, sleep outcomes, and anxiety and depression, the current study sample appears consistent with samples in previously published studies, which used alternative sampling methods.
DNA samples from previously published sources were used, with the exception of Turkmens, Tajiks, and Bashkirs, which were collected with the approval of the Independent Ethics Committee of the Institute of Biochemistry and Genetics, Ufa Research Center, Russian Academy of Sciences (decision No 17/10.10.2007).
38 For the evaluation of aneuploidy, we used flow cytometry on frozen samples, as previously published.
CNVRs were determined by aggregating overlapping CNVs identified across all samples, following previously published protocols [ 13].
Finally, a meta-analysis incorporating GRACE samples with previously published data for each SNP was performed.
Nine microarray datasets containing normal tissue samples from previously published studies were collected from the Gene Expression Omnibus (GEO).
We examined PTPRR gene expression in prostate cancer clinical samples using previously published datasets that are publically available.
It would not have been possible to study such small, easily obtained biological samples using previously published N-ChIP procedures.
