Abstract:
Glycosylation is one of the most common posttranslational modification reactions and nearly half of all known proteins in eukaryotes are glycosylated. In fact, changes in oligosaccharides structures are associated with many physiological and pathological events, including cell growth, migration and differentiation, and tumor invasion. Therefore, functional glycomics, which is a comprehensive study of the structures and functions of glycans, is attracting the increasing attention of scientists in various fields of life science. In cases of thyroid cancer, the biological characters and prognosis are completely different in each type of histopathology, and their oligosaccharide structures as well as the expression of glycosyltransferases are also different. In this review, we summarized our previous papers on oligosaccharides and thyroid cancers and discussed a possible function of oligosaccharides in the carcinogenesis in thyroid cancer.
Insights
Glycosylation, a key protein modification, impacts cell behavior and disease. This review explores oligosaccharide roles in thyroid cancer development and prognosis, linking glycan structures to histopathology.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Glycosylation is a prevalent posttranslational modification in eukaryotes, affecting nearly half of all proteins.
- Altered oligosaccharide structures are implicated in critical physiological and pathological processes, including cancer.
- Functional glycomics studies the structure and function of glycans, gaining importance in life sciences.
Purpose of the Study:
- To review previous research on oligosaccharides and thyroid cancer.
- To discuss the potential role of oligosaccharides in thyroid cancer development (carcinogenesis).
Main Methods:
- Literature review of studies on oligosaccharides and thyroid cancer.
- Analysis of histopathological differences and associated glycosyltransferase expression in thyroid cancer types.
Main Results:
- Thyroid cancer subtypes exhibit distinct biological characteristics and prognoses.
- Significant differences exist in oligosaccharide structures and glycosyltransferase expression across thyroid cancer histologies.
Conclusions:
- Oligosaccharide structures and their expression patterns are closely linked to thyroid cancer subtypes.
- Further investigation into the function of oligosaccharides in thyroid carcinogenesis is warranted.
