Such alterations may contribute to disrupted DNA synthesis, increased vulnerability to certain diseases, or differing responses to chemotherapy or supplementation.

UPP1 (Uridine Phosphorylase 1): UPP1 is an enzyme involved in the pyrimidine salvage pathway and converts uridine into uracil and ribose-1-phosphate. It plays a crucial role in nucleotide metabolism and supports the synthesis of DNA and RNA as well as other cellular processes. Its activity is particularly important during chemotherapy, as it influences the activation and effectiveness of certain anticancer drugs.

UST (Uronyl 2-Sulfotransferase) is an enzyme involved in the sulphation of proteoglycans, key components of the extracellular matrix. It plays an important role in biological processes such as cell signalling and tissue repair. Dysregulation of UST activity can affect connective tissue function and may be linked to disorders involving the extracellular matrix.

VCAN (Versican): VCAN is a gene that encodes versican, a large proteoglycan present in the extracellular matrix of tissues. Versican is involved in cell adhesion, migration, and tissue development. It plays a role in maintaining tissue structure and may contribute to processes such as wound healing and embryonic development.

XDH, or Xanthine dehydrogenase, is an enzyme that plays a crucial role in purine metabolism, which involves the breakdown and recycling of purine nucleotides such as adenine and guanine. XDH catalyses the conversion of hypoxanthine to xanthine, and then xanthine to uric acid, the final product of purine degradation in humans. This process is essential for eliminating excess purines from the body, helping to regulate levels derived from both diet and cellular turnover.

ZBTB49 (Zinc Finger and BTB Domain Containing 49) is a transcription factor involved in regulating gene expression through DNA binding and chromatin remodelling. As a member of the ZBTB family, it contributes to key cellular processes such as proliferation, differentiation, and development. Although the specific functions of ZBTB49 are not fully understood, its role in transcriptional regulation suggests it may influence cell fate decisions and could have important implications for cancer and developmental disorders.

ZFPM1 (Zinc Finger Protein, FOG Family Member 1): ZFPM1 is a cofactor that interacts with GATA family transcription factors, playing a key role in the development and differentiation of various cell types, particularly those in the heart and blood. It is essential for the differentiation of erythroid and megakaryocyte lineages. Mutations or dysregulation of ZFPM1 can affect haematopoiesis, potentially leading to blood disorders. Additionally, its role in cardiac development connects it to congenital heart defects. Research on ZFPM1 aims to enhance understanding of its function within gene regulation networks that govern cell fate decisions, with potential implications for treatments targeting these conditions.
