Conclusion
ZYG11B plays a tumor suppressive role in the proliferation process of colorectal cancer and may have a broad application prospect in the diagnosis and prognosis evaluation of colorectal cancer with more study.
Methods
The information of ZYG11B in colorectal cancer were downloaded from TCGA database. The bioinformatics analysis has been utilized to examine the expression, functional enrichment, association of immune, clinicopathological characteristics and diagnostic prognostic value. CCK-8 and apoptosis assays have been utilized to identify the abilities of progression and apoptosis. The abilities of invasion and migration were detected by transwell assay.
Results
In contrast to adjacent normal tissues, colorectal cancer tissues exhibited a notably diminished expression of ZYG11B (p < 0.001). Further examination through functional enrichment analysis unveiled the enrichment of various pathways associated with tumor proliferation and apoptosis. The implementation of CCK-8 and apoptosis assays validated the suppressive impact of ZYG11B on the progression of colorectal cancer cells (p < 0.001). A significant positive correlation was found between ZYG11B and Tcm and T helper cells (R ≥ 0.3, p < 0.001). Moreover, the expression of ZYG11B demonstrated a prominent presence among subjects without previous experience of colon polyps (p < 0.05), devoid of lymphatic infiltration (p < 0.01), and age ≤ 65 years (p < 0.01). Additionally, ZYG11B exhibited higher expression levels among patients diagnosed with colorectal adenocarcinoma (p < 0.05). Following the analysis of survival prognosis, it became evident that increased ZYG11B expression correlated with enhanced survival rates (p < 0.01) and the ability to accurately forecast the prognosis and survival of COAD/READ patients.
