Aberrant sialylation, a hallmark of cancer, involves sialidases that regulate sialic acid levels. These enzymes are closely linked to malignancy and show altered expression in cancer, making them potential diagnostic and therapeutic targets.

Area of Science:

  • Biochemistry
  • Oncology
  • Molecular Biology

Background:

  • Aberrant sialylation is a key feature of cancer cells, correlating with invasiveness and metastasis.
  • Sialidases, enzymes that remove sialic acid residues, regulate cellular sialic acid content and are implicated in biological processes.
  • Altered sialidase expression in cancer suggests their involvement in malignant transformation.

Purpose of the Study:

  • To investigate the role of sialidase alterations in malignant transformation.
  • To summarize the current understanding of sialidases in cancer from retrospective and prospective viewpoints.
  • To explore sialidases as potential targets for cancer diagnosis and therapy.

Main Methods:

  • Review of studies on sialidase expression changes during carcinogenesis.

    • Sialidase expression changes are closely associated with cancer malignancy.

    Conclusions:

    • Sialidases play a significant role in cancer malignancy.
    • Sialidase alterations are linked to cancer invasiveness and metastatic potential.
    • Sialidases represent promising targets for novel cancer diagnostics and therapeutics.
