The mRNA level of SOCS1 (Fig 1A), SOCS3 (Fig 1B), and SOCS5 (Fig 1C) was significantly lower in all cervical cancer cells tested than in normal cervix tissue and established normal colon (CCD-18Co) or lung fibroblast (CCD-18Lu, WI-38) cell lines,. This evidence concerns the gene SOCS3 and cervical cancer.
