ProteomicsThe changes in HNSCC cell lines (e.g., CAL-27 cetuximabR) after being treated with Cetuximab (500 ug/ml) for at least 2 months. We used LC-MS/MS to identify the main acetylation sites in resistance cell lines. In this study, it was found that the acetylation of STAT1 might hinder the downstream signaling of IFN-γ
Recent clinical trials revealed that prior use of Cetuximab may interfere with ICB efficacy. In this study, STAT1 protein levels changed after continued Cetuximab treatment (500 ug/ml). We used LC-MS/MS to compare the acetylation sites in wild-type and resistant cells. We proposed that the acetylati...

ProteomicsThe changes in HNSCC cell lines (e.g., OECM1) when treated with Cetuximab (500 ug/ml) at different passages. We used LC-MS/MS to identify the main target pathway. These findings could significantly enhance our evidence.
Recent clinical trials revealed that prior use of Cetuximab may interfere with ICB efficacy. In this study, STAT1 protein levels changed after continued Cetuximab treatment (500 ug/ml). We collected serial passages of cetuximab resistance HNSCC cell lines to perform LC-MS/MS. We identified the IFN p...

ProteomicsThe changes in cetuximab resistant HNSCC cell lines (e.g., OECM1-cetuximabR and CAL-27 cetuximabR) after being treated with Cetuximab (500 ug/ml) for at least 2 months. We used LC-MS/MS to identify the main phosphorylation sites in resistance cell lines.

TranscriptomicsBmi-regulated miRNA expression pattern in head and neck cancers
The critical role of Bmi1 in promoting stem cell properties has been shown in different type of human cancers. Here, we established four stable clones to study Bmi-regulated miRNA expression patterns in head and neck caners. Bmi1-overexpressing cell lines (FaDu- Bmi1vs. FaDu-pcDNA3 cell line), and k...

TranscriptomicsTranscriptome analysis of OECM1 after expression of let-7i
Expression of let-7i results in transcriptome alteractions in head and neck cancer cell line, OECM1. Stable transfection of pmCherry-let7i in OECM1 cell and analyzed the transcriptome by cDNA microarray. OECM1 transfected with pmCherry empty vector was used as a control of experiment.

TranscriptomicsThe expression level of microRNA after knockdown of Twist1 or Bmi1
To screen the microRNA regulated by Twist1 and Bmi1 Establish stable transfectants of pSUPER-sh-Twist1 or pSUPER-sh-Bmi1 in OECM1 cells and analyze the miRNA expression level of by microRNA microarray. OECM1 transfected with pSUPER-sh-scr was used as a control experiment.
