**Background of UPP1 Antibody**
Uridine phosphorylase 1 (UPP1) is an enzyme encoded by the *UPP1* gene, primarily involved in pyrimidine metabolism by catalyzing the reversible phosphorylation of uridine to uracil and ribose-1-phosphate. This enzyme plays a critical role in nucleotide salvage pathways, influencing cellular proliferation and survival. UPP1 is highly expressed in certain cancers, including colorectal, pancreatic, and hepatocellular carcinomas, where it is associated with aggressive tumor behavior and poor prognosis. Its overexpression is linked to enhanced pyrimidine recycling, supporting rapid cancer cell growth and resistance to chemotherapeutic agents like 5-fluorouracil (5-FU).
The UPP1 antibody is a valuable tool for detecting UPP1 protein levels in research and diagnostics. It enables the study of UPP1's role in tumor metabolism, drug resistance, and potential as a therapeutic target. Applications include Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to assess UPP1 expression patterns in tissues or cell lines. Recent studies also explore UPP1's involvement in immune modulation and its interaction with tumor microenvironments. As interest grows in targeting metabolic enzymes for cancer therapy, UPP1 antibodies contribute to elucidating mechanisms of UPP1 inhibition and evaluating novel therapeutic strategies.
