log 2 (ratio IFN-γ-treated / control) <strong>of</strong> BALB/c BMM<br />

Fig. R.3.2: Comparison <strong>of</strong> IFN-γ effects on gene expression pattern and protein abundance in BALB/c BMM and C57BL/6 BMM.<br />

A, C. Overview on numbers <strong>of</strong> differentially expressed genes in transcriptome analysis (A) and <strong>of</strong> proteins with significantly different<br />

abundance in LC-MS/MS analyses (C) when comparing IFN-γ effects in BALB/c BMM and C57BL/6 BMM.<br />

B, D. Log 2-transformed ratio data “IFN-γ treated BALB/c BMM” / “medium control BALB/c BMM” were plotted on the x-axis and log 2-<br />

transformed ratio data “IFN-γ treated C57BL/6 BMM” / “medium control C57BL/6 BMM” on the y-axis from transcriptome (B) and LC-<br />

MS/MS (D) analyses.<br />

Coloring distinguishes three different groups <strong>of</strong> regulated genes or proteins: Genes/proteins with significant differential<br />

expression/abundance caused <strong>by</strong> IFN-γ only in BALB/c BMM are shown in dark gray, while that with significant differential<br />

expression/abundance caused <strong>by</strong> IFN-γ only in C57BL/6 BMM are displayed in light gray. Genes/proteins significantly regulated <strong>by</strong><br />

IFN-γ in both BALB/c BMM and C57BL/6 BMM are colored in black. The minimal absolute fold change cut<strong>of</strong>f <strong>of</strong> 1.5 has been applied to<br />

all result lists.<br />

All transcriptome ratio data were derived from mean intensities <strong>of</strong> three biological replicates, and ratio data <strong>of</strong> LC-MS/MS analyses<br />

were derived from intensities <strong>of</strong> one biological replicate analyzed in technical triplicates <strong>of</strong> each group.<br />

Strain differences in gene expression [Maren Depke] and protein abundances [Dinh Hoang<br />

Dang Khoa] between BMM <strong>of</strong> BALB/c and C57BL/6 mice in untreated medium control and in<br />

IFN-γ treated samples<br />

The comparison <strong>of</strong> C57BL/6 BMM and BALB/c BMM at the non-treated medium control level<br />

and at the IFN-γ treated level resulted in 100 (control level) and 93 (IFN-γ treated level) genes<br />

that featured a higher expression in C57BL/6 BMM and 122 (control level) and 137 (IFN-γ treated<br />

level) genes that exhibited a higher expression in BALB/c BMM.<br />
