General description
Interleukin-11 (UniProt: P47873 ; also known as IL-11) is encoded by the Il11 gene (Gene ID: 16156) in murine species. IL-11 is member of the IL-6 family of cytokines that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to produce mature secreted protein. It is involved in a variety of biological responses, including hematopoiesis, bone development, and carcinogenesis. Its actions are mediated via interaction with IL-11 receptor that is composed of IL-11R and gp130. Binding of IL-11 to its receptor induces the activation of JAK that phosphorylates STAT3, which then translocates to the nucleus and activates transcription of various genes. IL-11 is reported to promote the proliferation of hepatocytes in response to liver damage. In mice subjected to liver injury, IL-11 is mainly produced by hepatocytes in response to reactive oxygen species (ROS) released from dying hepatocytes. Secreted IL-11 then induces STAT3 phosphorylation in adjacent healthy hepatocytes resulting in their compensatory proliferation. It has been reported that IL-11 production in dying hepatocytes depended on ERK2 that phosphorylates Fra-1 and prevents its proteasomal degradation. Fra-1 is subsequently recruited to the Il11 promoter and activates transcription. Clone 12-2E-6G (12) is suitable for detecting endogenous IL-11 in vivo by immunohistochemistry. It is shown to detect IL-11 positive cells in colon cancer in azoxymethane plus dextran sulfate treated wild-type mice but does not detect IL-11 positive cells in Il11-deficient mice or normal colonic tissue in wild-type mice.
