Deoxyuridine is a nucleoside composed of deoxyribose and uracil. It is a naturally occurring compound found in small amounts in DNA. Deoxyuridine can be synthesized through various methods, including enzymatic reactions and chemical synthesis. It has been studied for its potential therapeutic effects in cancer treatment, specifically in inhibiting DNA synthesis. Deoxyuridine can act as a substrate for thymidylate synthase, an enzyme crucial for DNA replication. By inhibiting this enzyme, deoxyuridine can potentially block the synthesis of thymidine, a key component of DNA. This inhibition of DNA replication can lead to cell death and potentially inhibit tumor growth. Deoxyuridine has also been investigated for its potential role in radiation therapy, where it can enhance the effectiveness of radiation treatment. It is believed that deoxyuridine can increase the sensitivity of cancer cells to radiation by interfering with DNA repair mechanisms. Despite its potential therapeutic applications, deoxyuridine's clinical use is limited due to its lack of specificity and potential side effects. Researchers continue to investigate its therapeutic potential and explore ways to improve its selectivity and efficacy.'

Glioma Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle.

Deficiency, Vitamin B 12 [description not available] | 0 | 10.37 | 79 | 2 |
Vitamin B 12 Deficiency A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis.
