Rare Cancer Meta-Analysis, pt.4: Clustering our meta-data with Partek Genomics Suite
Updated: Apr 3, 2018
This entry is part four in a series of instructional videos detailing a meta-analysis on eight different human gene expression studies looking at papillary renal cell carcinoma (pRCC). In this installment, I use Partek Genomics Suite to display the meta-data as a heat map and employ hierarchical clustering to find connected genes in the dataset based on its normalized gene scores across all 17 different comparisons. A text file containing the papillary meta-analysis used in this video can be accessed at this Google Drive link.
pt4.1: Review and introduction to heat maps and clustering
Inspiration for this meta-analysis on papillary kidney cancer came from an upcoming ‘Hackathon’ in May that brings together researchers, engineers and computer scientists to try to tackle challenging problems in life sciences. This year they are focusing on papillary renal-cell carcinoma type 1 (p1RCC), a disease that accounts for between 15 to 20% of all kidney cancers. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist.
