Given its role in cell proliferation, Cyclin D has significant clinical implications. Abnormal Cyclin D activity is a marker for various diseases, including cancers and hyperproliferative disorders. Assessing Cyclin D levels in tissue samples can aid in diagnosis, prognosis, and treatment planning. For instance, high Cyclin D1 expression in biopsy samples may indicate aggressive cancer, guiding oncologists in choosing appropriate therapeutic strategies.
