Background:
Epidemiological studies have found that hyperglycemia, is an independent risk factor for colorectal cancer (CRC), increasing colon cancer incidence and affecting the recurrence, metastasis, and prognosis in colon cancer patients. However, the intercorrelation between hyperglycemia and CRC risk is still unknown, In the present study, we sought to determine whether gene markers, which act in CRC with hyperglycemia, are silenced in CRC without hyperglycemia.
Methods:
In order to characterize the mechanism of functional genes associated with CRC with hyperglycemia, A total 24 CRC and matched controls were sequenced. Through bioinformatics analysis includes differential expression analysis, functional enrichment, new isoform prediction and alternative splicing event identification to found biomarker genes related to CRC development.
Results:
CRC patients with hyperglycemia were compared with patients without hyperglycemia, and we found that 21 genes were upregulated and 27 were downregulated. Further study showed that these genes are possibly of key genes involved in CRC development with hyperglycemia, such as mannan-binding lectin-associated serine protease 3 (MASP3), which has an immunological role in the activation of the complement system. Based on our comprehensive analysis, a cis-regulatory network for hyperglycemic CRC was reconstructed.
Conclusions:
Protein-protein interactions revealed the mechanisms of molecules involved in the interaction of hyperglycemia and cancer development. Our results provide further information on the metabolic pathway interaction with cancer pathways and elucidated the mechanisms of hyperglycemic factors function in cancer development from a transcriptomic perspective.
