Cancer&Entry Information
| Cancer Name | colon cancer |
| ICD-0-3 | C18 |
| Methods | qPCR, Western blot, Luciferase reporter assay etc. |
| Sample | cell lines (CCL228, HeLa, MCF7, SH-SY5Y) |
| Expression Pattern | up-regulated |
| Function Description | Along with HIF1a, histone methylases MLL1 and histone acetylase p300 are enriched at the HOTAIR promoter under hypoxia. The levels of H3K4-trimethylation and histone acetylation are also enriched at the HOTAIR promoter. Furthermore, knockdown of MLL1 downregulated the hypoxia-induced HOTAIR expression, indicating key roles of MLL1 in hypoxia-induced HOTAIR expression. HIFs are transcription factors and regulate the expression of a variety of target genes under hypoxia and that contribute to the tumor growth and metastasis.Misregulation and mutations in lncRNAs are widely associated with a variety of human diseases. |
