Representative ethidium bromide stained 2% agarose gel showing semiquantitative Reverse Transcriptase polymerase chain reaction (RT-PCR) analysis and quantification of STAT3 (298 bp) mRNA expression at different stages of soft tissue tumors v/s GAPDH (269 bp) (A and B). Lane 1: benign soft tissue tumor; lane 2: intermediate soft tissue tumor; lane 3: malignant soft tissue tumor. A 100-bp ladder was used as a size standard.
