Heparin also decreased the TNF‑α‑induced mRNA and protein expression levels of IL‑6, IL‑8, TNF‑α and cyclin D1 in a dose‑dependent manner. Immunofluorescence analysis showed that the expression of cytoplasmic TNF‑α was significantly reduced by heparin treatment. Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. Since heparins depend on the activity of antithrombin, they are considered anticoagulants. Specifically it is also used in the treatment of heart attacks and unstable angina.
