An in-depth look at how
An in-depth look at how we to measure and analyze tens of thousands of DNA probes simultaneously using RT-qPCR and micro-arrays. With applied examples in the R language for statistical computing.

Chapters:
00:00 Gene Expression Analysis, Question we want to solve
02:07 Real Time qPCR compared to genomic PCR, The delta delta CT method
05:58 Macro and microarrays to measure thousands of probes at the same time
07:30 Real Time qPCR and microarray workflow
08:30 Probe hybridisation due to complementary base pairing
10:15 One color versus Two-Color microarrays
12:04 Comparative Genomics, Expression Profiling, SNP Genotyping, ChIP-on-chip epigenetics
15:13 Microarray workflow: the Cy3 and Cy5 dyes
20:34 Into the data - Normalization
23:12 Microarrays, what could go wrong ? (and does)
25:52 Background correction of microarrays
27:58 Spatial normalization of microarrays
29:20 Bioconductor packages: RMA, GC-RMA, MAS 5, LOESS
30:26 After preprocessing: Expression matrix data overview
31:33 Processing the signal intensity data into Log2 Ratio
34:47 Dye bias is related to their Dynamic Range
35:57 Normalization as a concept, two goals and definitions
39:11 Quantile Normalization via preprocessCore, risks
42:50 Differentially expressed genes
44:25 T-test, average, standard deviations, T-statistics, Significance table
47:09 Analysis of Variance, multiple groups, covariates
50:29 ANOVA table, Two mouse strains and their offspring
This is a live-stream recording of the MSc and PhD lecture series: #Bioinformatics for plant and animal sciences, given digitally during the Covid19 pandemic at the Humboldt University in Berlin organized and lectured by Dr Danny Arends.
