Reduced expression of Hugl-1, the human homologue of Drosophila tumour suppressor gene lgl, contributes to progression of colorectal cancer.
2005
The human gene, human giant larvae (Hugl-1/Llg1/Lgl1) has significant homology to the Drosophila tumour suppressor gene lethal(2)giant larvae (lgl). The lgl gene codes for a cortical cytoskeleton protein, Lgl, that binds Myosin II and is involved in maintaining cell polarity and epithelial integrity. The human protein, Hugl-1 contains several conserved functional domains found in Lgl, suggesting that these proteins may have closely related functions. Whether loss of Hugl expression plays a role in human tumorigenesis has so far not been extensively investigated. Thus, we evaluated tumour tissues from 94 patients undergoing surgery for colorectal cancer (CRC) for loss of Hugl-1 transcription…
Expression of Hugl-1 is strongly reduced in malignant melanoma.

The human gene Hugl-1 (Llgl/Lgl1) has significant homology to the Drosophila tumor suppressor gene lethal(2)giant larvae (lgl). The lgl gene codes for a cortical cytoskeleton protein, Lgl, that is involved in maintaining cell polarity and epithelial integrity. We speculate that Hugl-1 might play a role in epithelial-mesenchymal transition (EMT) and that loss of Hugl-1 expression plays a role in the development or progression of malignant melanoma. Thus, we evaluated melanoma cell lines and tissue samples of malignant melanoma for loss of Hugl-1 transcription. We found that Hugl-1 was downregulated or lost in all cell lines and in most of the tumor samples analysed, and that these losses wer…
