Abstract
In the present study, we investigated mRNA expression patterns of both SOCS5 and SOCS6 in various normal and cancer tissues using a commercially available Cancer Profiling Array. We found that SOCS5 and SOCS6 had similar expression patterns in most cancer and healthy individuals, suggesting that these two genes are transcriptionally co-regulated. Tissue-specific up- or down-regulation of SOCS5 and SOCS6 was observed in several cancer tissues. Most importantly, thyroid gland cancer tissues exhibited large reductions of both SOCS5 and SOCS6 expressions. In addition, mRNA and protein levels of SOCS6 were down-regulated in liver cancer tissues. The results from our study may contribute to understanding SOCS5 and SOCS6 expression regulation in various cancer tissues, and show that these two factors may be used for diagnosing cancer.
