Principal component analysis of temporal gene expression profiles identified two major gene classes each exhibiting a distinct coordinate differential expression pattern.
Proteome analyses revealed that rhodomyrtone at subinhibitory concentration (0.174 µg/ml) affected the expression of several major functional classes of whole cell proteins in MRSA.
The phosphoproteins with expression alterations encompass all major protein classes, including a large number of nucleic acid binding proteins.
Furthermore, T. carassii infections were characterized by an increase in gene expression of major histocompatility class II genes and the matrix metalloproteinase MMP-9 (Table 2).
TSLP induces DCs to up-regulate the expression of major histocompatibility class I and II and costimulatory molecules, including CD40, CD80, CD86.
Macrophage presence/function also played an important role and was associated with over-expression of major histocompatiblity class II genes supporting the presence of activated macrophages in infected GI-101A xenografts.
According to visual inspection of the GEP histograms, we proposed that there were four major classes of gene expression profiles.
The content of this final set of genes was explored by hierarchical and agglomerative clustering in the Acuity system to identify the major classes of gene expression changes, as reported above.
Honoring our proposition that there are four major classes of gene expression profiles, we clustered the genes by K-Means clustering (KMC) with k = 4 based on the mean, standard deviation, kurtosis, and skewness of the expression intensity profile for each gene.
Indeed, glucocorticoids can enhance tumour cell resistance to immune response, inactivate B and T lymphocytes, reduce major histocompatibility class I antigen expression, leading to a reduction in the tumour immunosurveillance even at very low doses [ 40– 40].
