Cornulin transcriptomic analysis in Cal27 oral cancer cells

ABSTRACT: RNA-Seq profiling of Cal27 Oral squamous carcinoma cells overexpressing Cornulin (CRNN), GFP control, and untreated group (UNT) to study differential gene expression. This project investigates the transcriptomic alterations induced by the overexpression of Cornulin (CRNN) in the Cal27 human oral squamous cell carcinoma cell line. The study design included three experimental groups: (1) Cornulin-overexpressing Cal27 cells, (2) GFP-expressing Cal27 cells as vector controls, and (3) untreated Cal27 cells. Total RNA was extracted using Trizol reagent, followed by RNA quality assessment via Bioanalyzer. Strand-specific mRNA libraries were prepared using the TruSeq Stranded mRNA kit, pooled at 6 nM, and sequenced using an Illumina NovaSeq 6000 S4 flow cell in a paired-end (2x100 bp) configuration. Raw FASTQ files were analyzed by aligning to the human genome (GRCh38), and gene-level quantification was performed. Differential expression analysis was conducted using the DESeq2 R package. DEG lists from each comparison group were subjected to pre-ranked gene set enrichment analysis (GSEA) to identify enriched pathways and gene ontologies. The dataset provides insights into Cornulin-mediated gene regulation.

Expression data from oral squamous cell carcinoma cell line Cal27 after lentivirus shIL-1beta transfection

Project description:Oral squamous cell carcinoma cell line Cal27 was transfected with lentiviral shIL-1beta or scrambled shRNA. We used microarrays to detail the global program of gene expression during this process. IL-1beta was identified as one of the key node genes in oral carainogenesis in our preveious in vitro study. This in vivo study was designed to confirm the role of IL-1 beta and explore some more detail about the evolvment of IL-1 in malignant transformation.

RBM24 regulates apoptosis rates by modulating global transcriptome profile in CAL27 cells [iRIP-seq]

Project description:RNA binding proteins (RBPs) are key factors regulating post-transcriptional events. Categorized as RBPs, RBM24 expression levels have been shown to be a prognosis-related pivotal gene in oral squamous cell carcinoma. We analyzed the binding targets and regulated post-transcriptional events of RBM24 in RBM24-overexpressing cell lines and controls using iRIP-seq and RNA-seq. RBM24-overexpressing cells showed significant changes in gene expression, which are involved in biological pathways related to apoptosis and immune inflammation. RBM24-regulated genes that undergo alternative splicing are primarily engaged in biological processes related to DNA damage repair and RNA metabolism. More notably, we found that RBM24 binds to lncRNAs in addition to pre-mRNAs. These results indicated that RBM24 could play a key role in cancer progression by finding clinical therapeutic targets for Oral squamous cell carcinoma.

Expression data from Head and neck squamous cell carcinoma cell lines cell line Cal27 after TCF19 knockout mediated by CRISPR/CAS9

Project description:The deletion of TCF19 in CAL27,oral squamous cell carcinoma cell line,was conducted by using CRISPR/Cas9 system. For WT and TCF19 KO CAL27 cell lines, samples were done in triplicates. A total of 3μg of high-quality RNA per sample was used for ribosomal RNA removal by the Epicentre Ribo-zero rRNA Removal Kit (Epicentre, USA) and the sequencing library was prepared using the rRNA-depleted RNA by the NEBNext Ultra Directional RNA Library Prep Kit for Illumina (NEB, USA) following manufacturer’s recommendations. The clustering of the index-coded samples was performed on a cBot Cluster Generation System using TruSeq PE Cluster Kit v3-cBot-HS (Illumina, San Diego, CA, USA), followed by the 150-bp paired-end sequencing on the HiSeq X Ten instrument (Illumina, San Diego, CA, USA) according to the manufacturer’s protocols.

Expression data of Oral squamous cell carcinoma (OSCC) cell lines CAL27, SCC4 and SCC25 treated with oral commensals

Project description:Oral bacterial species Streptococcus mitis, Neisseria flavescens, and Haemophilus parainfluenzae, and Porphyromonas gingivalis were each co-cultured with the OSCC cell lines CAL27, SCC4 and SCC25 individually. Total RNA was extracted from the cell lines, followed by gene expression profiling with microarray analysis.

Cornulin, a potential prognostic biomarker in head and neck squamous cell carcinoma, acts as an anti-tumour agent by inhibiting cell cycle through upregulation of p18.

Project description:The xenograft models were developed using 4–6-week-old CD1-Foxn1nu nude male mice and subcutaneously inoculating HNSCC cell lines, i.e., Cal27. In each mouse, the left flank received Cal27 untreated cells and the right flank received Cal27 Cornulin-overexpressing cells to allow within-animal comparison. After tumor development, mice were sacrificed, and xenograft tumors were excised. Tumor tissues were then subjected to protein extraction, tryptic digestion, and LC-MS/MS-based proteomic analysis to identify differentially expressed proteins associated with Cornulin overexpression in vivo.

The tongue squamous carcinoma cell line Cal27 primarily employs integrin α6β4-containing type II hemidesmosomes for adhesion which contribute to anticancer drug sensitivity

Project description:Integrins are heterodimeric cell surface glycoproteins used by cells to bind to the extracellular matrix (ECM) and regulate tumor cell proliferation, migration and survival. A causative relationship between integrin expression and resistance to anticancer drugs has been demonstrated in different tumors, including head and neck squamous cell carcinoma. Using a Cal27 tongue squamous cell carcinoma model, we have previously demonstrated that de novo expression of integrin αVβ3 confers resistance to several anticancer drugs (cisplatin, mitomycin C and doxorubicin) through a mechanism involving downregulation of active Src, increased cell migration and invasion. In the integrin αVβ3 expressing Cal27-derived cell clone 2B1, αVβ5 expression was also increased, but unrelated to drug resistance. To identify the integrin adhesion complex (IAC) components that contribute to the changes in Cal27 and 2B1 cell adhesion and anticancer drug resistance, we isolated IACs from both cell lines. Mass spectrometry (MS)-based proteomics analysis indicated that both cell lines preferentially use integrin α6β4, which is classically found in hemidesmosomes. The anticancer drug resistant cell clone 2B1 demonstrated an increased level of α6β4 accompanied with increased deposition of a laminin-332-containing ECM. Immunofluorescence and electron microscopy demonstrated the formation of type II hemidesmosomes by both cell types. Furthermore, suppression of α6β4 expression in both lines conferred resistance to anticancer drugs. Taken together, our results identify a key role for α6β4-containing type II hemidesmosomes in regulating anticancer drug sensitivity.

Cell contractility drives mechanical memory of oral squamous cell carcinoma

Project description:To study if non-invasive oral squamous cell carcinoma (OSCC) cells can acquire mechanical memory from stiff matrix and investigate the role of cell contractility in that process, Cal27 were conditioned (for 5 days) either by matrix stiffness or by direct modulation of cell contractility and then replated to a new niche lack of sources for the cells to learn. Cal27 with different types of conditioning were categorized either "Learn" or "Don't Lean/Forget" based on the existence of mechanical memory. Comparative gene expression profiling was done between "Learn" vs. "Don't Learn/Forget" Cal27 groups by RNA sequencing
