Young tableaux are certain tabular arrangements of integers. Alfred Young introduced them to describe irreducible representations of the symmetric group at the end of the 19th century. We will use combinatorial algorithms of permutations and Young tableaux to describe a modification of the research method of Ahnert et al for identifying significant genes in the biological processes studied in microarray experiments. In the last decade, DNA microarrays (DNA chips) have been used to study gene expressions in many diseases such as cancer and diabetes. To analyze data of microarray expression curves of genes, Ahnert et al associated permutations to the data points of the microarray curves. Using Monte- Carlo simulation they established bounds corresponding to various maps of permutations for any microarray curve's algorithmic compressibility which measures its significance in the underlying biological process. Using the Robinson- Schensted-Knuth procedure, we will associate Young tableaux to permutations corresponding to the data points of microarray curves. We will calculate the bound of Ahnert et al corresponding to the map which gives the length of the longest increasing or decreasing subsequence of a permutation. [ABSTRACT FROM AUTHOR] |
