Figure S1. Microarray analysis of H60a-hi and H60a-lo MCA sarcoma cell lines shows that A20 (tumor necrosis factor, alpha-induced protein 3) is expressed highly in some H60a-hi cell lines but is poorly expressed in all H60a-lo cell lines.

Figure S2. Measurement of A20 by qRTPCR shows a trend for H60a-hi cells to have more A20 than H60a-lo cells.

Figure S3. Inhibition of the NF-kB pathway by slz and BAY-11-7085 induced H60a expression.

Figure S4. TNF stimulation does not alter H60a levels significantly. A20 is induced at early timepoints.
