Single-cell Sequencing Analysis Identifies Intratumoral Immune Cell Population in Head and Neck Squamous Cell Carcinoma from 4NQO-induced Mice upon JQ1 treatment

ABSTRACT: In this study, we aimed to identify the landscape alterations of the subpopulations of the tumor-infiltrating immune cells in HNSCC from 4NQO-induced mice upon JQ1 treatment; by using single cell sequencing analysis, we characterized the alterations of intratumoral T cell subpopulations by separating T cells and yielded 9 distinct T cell subpopulations defined by the distribution of classical marker genes, including Tregs, naïve-like cell, γδ T cells 1, IFNG+ HSP+ T cell, CD8+ cytotoxic T cell, CD4+ T effector cell, γδ T cells 2, Xcl1+ T cells and ILC2. In comparison with mice treated with control, JQ1 treatment resulted in an increase of the percentage of CD8+ T cells and Xcl1+ T cells, indicating an activated tumor immune microenvironment in primary HNSCC upon JQ1 treatment.

Single-cell Sequencing Analysis Identifies Intratumoral Cell Population in Head and Neck Squamous Cell Carcinoma from 4NQO-induced Mice upon anti-CD276 Therapy

Project description:In this study, we aimed to identifies the landscape alterations of intratumoral cell population in HNSCC from 4NQO-induced mice upon anti-CD276 treatment by using single cell sequencing analysis.we characterized the alterations of intratumoral cell population by separating cancer cells and yielded 6 distinct cancer cell subpopulations defined by the transcriptional state of cells and known marker genes, including the sunpopulation with pEMT, stress, typical epithelial differentiation, high cell-cycling, metabolism and immune fetures. In response of CD276 treatment, the frequecey of cells with pEMT, cell cycling and immune features are dcreased as compared to the vehicle control mice.

Therapeutic targeting of BRD4 in head neck squamous cell carcinoma

Project description:The bromodomain and extraterminal family members are epigenetic readers and transcriptional coactivators which are critically involved in various biological processes including tumorigenesis. BRD4 has been increasingly appreciated as a key oncogene and promising anticancer target. Here, we sought to characterize the expression of BRD4 and its tumorigenic roles as well as therapeutic targeting in HNSCC. Expression of BRD4 mRNA and protein was determined by bioinformatics interrogation of public available databases, primary HNSCC samples and 4NQO-induced HNSCC animal model. The tumorigenic roles of BRD4 in HNSCC were evaluated by genetic and pharmacological approach in vitro and in vivo. Therapeutic efficiency of BRD4 targeting by JQ1 was assessed in three preclinical models including xenograft model, 4NQO-induced model and patients-derived xenograft model. Gene candidates responsible for therapeutic effects of JQ1 were identified by transcriptional profiling in HNSCC cells after JQ1 exposure. Significant upregulation of BRD4 was found in primary HNSCC samples and 4NQO-induced HNSCC model. Its overexpression associated with aggressive clinicopathological features and inferior overall and disease-free survival. BRD4 depletion by genetic silencing or pharmacological inhibition impaired cell proliferation, migration and invasion and reduced tumor growth and metastasis in vivo. Transcriptional profiling of HNSCC cells following JQ1 exposure identified hundreds of genes which might mediated its antitumor effects and enriched in cancer-relevant pathways. A novel prognostic risk score derived from JQ1-regualted genes was developed to stratify patients into subgroups with favorable or inferior prognosis. Our findings reveal that BRD4 serves as a novel oncogene driving cancer progression and a robust prognostic biomarker in HNSCC. Therapeutic targeting of BRD4 represents a potent and promising strategy against HNSCC.

Transcriptomes Analysis of 4NQO induced-esophageal tumors of Wild Type and S100A14 CKO mice

Project description:Purpose: To fully realize the potential molecular mechanism that S100A14 deficiency enhances esophageal carcinogenesis Methods: Total RNA of esophageal tumors in 4NQO WT and 4NQO S100A 14 CKO group mice was extracted with TRIzol Reagent. RNA libraries were constructed using an Illumina TruSeq RNA Sample Preparation kit according to the manufacturer’s protocol. A total of 150 base paired-end reads were sequenced using the Novaseq 6000 S4 platform. The read alignment was conducted using TopHat 2.0.13, and relative transcript abundances and differentially expressed genes were determined using the DESeq R package. Results: We identified 14,157 transcripts in esophageal tumors of 4NQO WT and 4NQO S100A14 CKO group mice. Approximately 8% of the transcripts showed differential expression between the esophageal tumors of 4NQO WT and 4NQO S100A 14 CKO group mice, with a fold change ≥1.0 and p value <0.05. Conclusions: Our study represents the first analysis of esophageal tumors derived from S100A14 CKO mice with biologic replicates, generated by RNA-seq.

RNA-seq analysis of HNSCC cells after JQ1 treatment

Project description:We performed RNA sequencing (RNA-seq) of HNSCC cells to examine genome-wide gene expression pattern following JQ1 treatment. BET inhibition by JQ1 significantly inhibits a cohort of key oncogenes associate with tumorigenesis and metastasis. Suggesting BET inhibition is effective strategy to suppress the tumorigenesis and metastasis of head and neck squamous cell carcinoma.

ChIP-Seq for Yrr1 protein on Saccharomyces cerevisiae cells carrying different YRR1 alleles in response to 4-nitroquinoline-N-oxide (4NQO)

Project description:In this study, we constructed three isogenic strains of S96 yrr1Î background (its native YRR1 gene was knocked out) carrying three different YRR1 alleles, YRR1_S96, YRR1_YJM789, YRR1_S96-I775E, respectively. We then conducted chromatin immuno-precipitation followed by high-throughput sequencing (ChIP-Seq) for Yrr1 protein on the three strains grown in Yeast Peptone Dextrose medium (YPD) and YPD + 4NQO. ChIP-Seq for Yrr1 protein was performed in biological triplicates on S96 cells carrying three different YRR1 alleles grown in YPD and YPD + 4NQO. Immune-precipitated DNA were sequenced for all the three cultures and input genomic DNA was sequenced for one culture.
