Protein synthesis in reticulocytes depends on the availability of heme. In heme deficiency, inhibition of protein synthesis correlates with the activation of heme-regulated eIF-2alpha kinase (HRI), which blocks the initiation of protein synthesis by phosphorylating eIF-2alpha. HRI is a hemoprotein ...
Severe Vitamin K deficiency would affect both PT and aPTT since the synthesis of certain coagulation factors in both arms of the coagulation cascade depends on vitamin K (in particular, factors II, VII, IX, and X and proteins C and S). Similarly, the dilution effect of intravenous fluid ...

In inflammatory conditions including certain chronic diseases, there may be a normal or sometimes increa...

Suppression of red blood cell synthesis secondary to the use of chemotherapeutic drugs. Abnormal hemoglobin structure such as in patients with sickle cell anemia. (4, 5, 6, and 7) How to increase hemoglobin levels? Increasing the level of hemoglobin can be done in many different ways. You ca...
The clinical course of both α and β thalassemia is heterogeneous and depends in part on the impairment of globin synthesis and the ratio of α and non-α chains. Current therapies Treatment is imperfect. The management of sickle cell anemia and β thalassemia begins with carrier detection and...
The size of the adenine nucleotide pool depends on the synthesis and degradation of one component of this pool, AMP22. The intracellular catabolism of AMP is primarily carried out by AMPD. The three known tissue-specific isoforms of the enzyme, AMPD1, AMPD2 and AMPD3, are expressed in ...
Mutations resulting in reduced synthesis of one of the chains are called thalassemias. They can result from deletion of the gene for a chain or from a mutation in the regulatory gene that controls the synthesis of the chain. The life cycle of red blood cells and the breakdown of hemoglobin...
