Abstract
Background
Lactylation plays an essential role in pancreatic cancer, but the precise role of lactylated histone in the diagnosis and prognosis of pancreatic cancer remains to be further clarified.
Methods
Twenty-one patients diagnosed with pancreatic cancer were enrolled in this study, and the clinicopathologic characteristics were collected. Lactylation levels of total proteins and histone H3 Lysine-18 (H3K18) of tissues were determined by western blotting and laboratory indicators including serum levels of lactate, Cancer Antigen 19–9 (CA19–9), and Carcinoembryogenic Antigen (CEA) were obtained.
Results
Total protein lactylation was found in both pancreatic cancer tissues and para-carcinoma normal tissues, and was more potent in tumor tissues. H3K18la was also highly expressed tumor tissues. Furthermore, H3K18la protein expression correlated positively with serum lactate (r = 0.774, p < 0.001), CA19–9 (r = 0.744, p < 0.001), and CEA (r = 0.589, p < 0.01). The Area Under the Curve (AUC) of H3K18la for the diagnosis of pancreatic cancer was 0.848 in serum (p < 0.001).
Conclusion
The present findings suggested that H3K18 may be used as a novel potential biomarker for the diagnosis and prognosis of pancreatic cancer patients.
