Figure 5. hCG modulates IL1B effects on the expression of IL1 family members in ESCs.

Figure 5

Confluent ESC cultures were incubated with minimal medium (MM) or hCG (100 ng/mL) for 24 h before being exposed or not to IL1B (0.1 ng/mL) for additional 24 h. Total RNA was extracted and reverse transcribed, and mRNA levels were then quantified by qRT-PCR. IL1A (A), IL1B (D), IL1RL1 (B), IL18R1 (E), IL33 (C) and IL18 (F) mRNA ratio was then determined following normalization to GAPDH mRNA (internal control). Data were from ESC cultures issued from 7 different subjects and expressed as fold change (FC) over control (ratio of IL1A, IL1B, IL1RL1, IL18R1, IL33 or IL18 mRNA levels found in cells incubated with IL1B, hCG or hCG/ILB to those found in cells incubated with MM for an equivalent period of time). *P<0.05, **P<0.01, *** P<0.001 relative to MM; †P<0.05, †††P<0.001 relative to cells stimulated with an equivalent concentration of hCG; ++P<0.01 relative to cells stimulated with an equivalent concentration of IL1B. Data were obtained with ESC cultures issued from 7 different subjects (the 3 cultures used for microarray analysis and 4 additional cultures).
