A key gene in cancer research
Meflin(Islr) functional analysis tools
|Meflin (Islr: Immunoglobulin Superfamily Containing Leucine Rich Repeat) is a GPI (glycosylphosphatidylinositol)-anchored membrane protein. The depositor (Dr. Enomoto) and his colleagues identified Meflin as a molecular marker for undifferentiated mesenchymal stromal cells and fibroblasts. In the field of cancer research, Meflin is known as a functional marker of rCAFs (cancer-restraining cancer-associated fibroblasts) [1-4]. Meflin has been reported to be involved in inhibition of cancer progression via BMP signaling pathway in various cancers such as colorectal and pancreatic cancer. Therefore, Meflin has attracted attention as a novel cancer therapeutic target [5-8]. Synthetic retinoid AM80 has already been identified as a compound that enhances Meflin expression and converts pCAFs (cancer-promoting CAFs) to rCAFs. Clinical trials on the efficacy of AM80 in combination with anticancer drugs have been initiated [9,10]. RIKEN BRC can provide three strains: Meflin KO mice (RBRC09446), Meflin tamoxifen-induced Cre driver mice (RBRC11436), Meflin reporter mice (RBRC11437) that express fluorescent protein ZsGreen, DTR (Diphtheria toxin receptor), and Cre enzyme under the control of endogenous Meflin promoter simultaneously. In the near future, getting more understanding of Meflin-related cancer molecular mechanisms will lead to therapeutic applications in the clinical field.|
