Objective:
Nucleosome assembly protein 1-like 1 (NAP1L1) plays an important role in the development and progression of several types of cancer.
Subject And Methods:
This study investigated the association between NAP1L1 polymorphisms, particularly rs11180813, and susceptibility to oral squamous cell carcinoma (OSCC).
Results:
Our study showed that betel quid chewing and cigarette smoking were significantly associated with OSCC risk (p < 0.001). No significant correlation was found between NAP1L1 SNPs and overall OSCC susceptibility. However, among OSCC patients, patients with rs11180813 variant genotypes (GC/CC) were associated with lymph node metastasis (adjusted OR = 1.565, 95% CI = 1.042-2.350, p = 0.031) and poor tumor differentiation (adjusted OR = 2.284, 95% CI = 1.126-4.635, p = 0.022). In buccal OSCC, the rs11180813 variant was associated with lymph node metastasis (adjusted OR = 2.349, 95% CI = 1.213-4.549, p = 0.011). TCGA analysis revealed that high NAP1L1 expression correlated significantly with lymph node metastasis and poor tumor differentiation (p < 0.0001).
Conclusion:
These findings suggest that NAP1L1 and its rs11180813 polymorphism may be associated with certain clinicopathological characteristics of OSCC, particularly lymph node metastasis and tumor differentiation. Further studies are required to validate their clinical significance.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
