Abstract

Background: Frequent mutations in the nuclear receptor binding SET domain protein 1 (NSD1) gene have been observed in head and neck squamous cell carcinomas (HNSCC). NSD1 encodes a histone 3 lysine-36 methyltransferase. NSD1 mutations are correlated with improved clinical outcomes and increased sensitivity to platinum-based chemotherapy agents in human papillomavirus-negative (HPV-) tumors, despite weak T-cell infiltration. However, the role of NSD1 and related family members NSD2 and NSD3 in human papillomavirus-positive (HPV+) HNSCC is unclear.

Methods: Using data from over 500 HNSCC patients from The Cancer Genome Atlas (TCGA), we compared the relative level of mRNA expression of NSD1, NSD2, and NSD3 in HPV+ and HPV- HNSCC. Correlation analyses were performed between T-cell infiltration and the relative level of expression of NSD1, NSD2, and NSD3 mRNA in HPV+ and HPV- HNSCC. In addition, overall survival outcomes were compared for both the HPV+ and HPV- subsets of patients based on stratification by NSD1, NSD2, and NSD3 expression levels.

Results: Expression levels of NSD1, NSD2 or NSD3 were not correlated with altered lymphocyte infiltration in HPV+ HNSCC. More importantly, low expression of NSD1, NSD2, or NSD3 correlated with significantly reduced overall patient survival in HPV+, but not HPV- HNSCC.

Conclusion: These results starkly illustrate the contrast in molecular features between HPV+ and HPV- HNSCC tumors and suggest that NSD1, NSD2, and NSD3 expression levels should be further investigated as novel clinical metrics for improved prognostication and patient stratification in HPV+ HNSCC.

Figures

**Fig. 1**
Expression of *NSD1*, *NSD2*, and *NSD3* genes in HNSCC stratified by HPV status. Normalized RNA-seq data was extracted from TCGA database for the HNSCC cohort for HPV+, HPV-, and matched normal-adjacent control tissues. Numbers in brackets refer to the number of samples included in each analysis. Statistical p value significance levels are indicated as follows: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001; ns – not significant

**Fig. 2**
Correlation matrix of *NSD* paralogs and viral oncogene expression. Normalized RNA-seq data for *NSD1*, *NSD2*, *NSD3*, HPV E6, and HPV E7 was compared in a pairwise fashion for both the HPV+ (left) and HPV- (right) TCGA HNSCC cohorts. Numbers indicated in the boxes are the calculated Spearman’s rank correlation coefficient of the indicated gene pairs. Statistical p value significance levels are indicated as follows: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001; ns – not significant

**Fig. 3**
T-cell infiltration is higher in HPV+ HNSCC compared to HPV- and normal control counterparts. A previously reported 13 gene T-cell transcript signature was calculated for HPV+, HPV-, and matched normal-adjacent control tissues. Numbers in brackets refer to the number of samples included in each analysis. Statistical p value significance levels are indicated as follows: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001; ns—not significant

**Fig. 4**
T-cell infiltration is not correlated with *NSD1* expression in HPV+ HNSCC, but is weakly correlated in HPV- HNSCC. A previously reported 13 gene T-cell transcript signature was calculated for each sample in the TCGA HNSCC cohort and compared pairwise with normalized RNA-seq data for *NSD1*, *NSD2*, and *NSD3* for HPV+ (a) and HPV- (b) HNSCC samples. For each *NSD* paralog, the correlation with the T-cell transcript signature was calculated by Spearman’s Rho analysis

**Fig. 5**
Low *NSD1*, *NSD2*, or *NSD3* expression is strongly associated with reduced survival in patients with HPV+ but not HPV- HNSCC. Overall survival of patients grouped by high, mid, or low expression of *NSD1*, *NSD2*, or *NSD3* in the HPV+ (a) and HPV- (b) HNSCC cohorts. Comparison between groups were calculated with the 2-sided log-rank test (p value) and multiple comparisons corrected with the Benjamini–Hochberg method utilizing an FDR threshold of 10% (q value). Numbers in brackets indicate the number of samples included in each expression group
