Disease Name: | Uterine Cervical Neoplasms |
Sample: | cervical cancer tissues |
Dysfunction Pattern: | Expression(lower expressed) |
Validated Method: | RNA Pull-Down//Transfection//Tube Formation Assay//CCK8//qRT-PCR//RIP//FISH//Luciferase Report Assay//Microarray//ELISA//Transwell Assay//Bioinformatics Analysis//IF |
Description: | Herein, through RNA screening, we identified a novel long noncoding RNA (lncRNA), LncCCLM, that was downregulated in cervical cancer tissues and closely associated with lymphatic metastasis in cervical cancer patients. Mechanistically, LncCCLM localized in the cytoplasm and interacted with staufen double-stranded RNA binding protein 1 (STAU1), promoting the binding of the STAU1 protein to the 3' untranslated region (3'UTR) of insulin-like growth factor 1 (IGF-1) mRNA, which accelerated the degradation of IGF-1 mRNA and decreased the IGF-1 protein level, ultimately reducing lymphangiogenesis and lymphatic metastasis in cervical cancer. |
Causality: | Yes |
Causal Description: | Gain-of-function and loss-of-function studies in CC cells demonstrated that LncCCLM inhibited cervical cancer-associated lymphangiogenesis, and CC cell migration and invasion in vitro and suppressed LN metastasis in vivo, but did not affect the growth of CC cells. |
Clinical-realted Application: | Herein, through RNA screening, we identified a novel long noncoding RNA (lncRNA), LncCCLM, that was downregulated in cervical cancer tissues and closely associated with lymphatic metastasis in cervical cancer patients. |
