Colla corii asini might upregulate ZNF471 and THOC5 by KRAB domain –containing zinc-finger protein pathway and THO complex subunit 5 pathway to improve anemia of pregnant women with β-thalassemia

AbstractPregnant patients with β-thalassemia are more likely to have progressive anemia which expose them to risk of adverse pregnancy outcomes, blood transfusion, and iron overload. Results from our previous study indicated thatColla corii asini (CCA, E ’jiao), a natural ingredient of traditional Chinese medicine, could significantly increase hemoglobin level of pregnant women with β- thalassemia, but the underlying molecular mechanism was unclear. Thus, we applied high-throughput transcriptome sequencing to study the transcriptomic change befor e and after the CCA treatment. Twenty eligible pregnant women were recruited and randomized to either the CCA treatment group or the blank control group in a 3:1 ratio. Patients in the treatment group orally received daily 15 g CCA powder for 4 weeks. We analyzed the therapeutic effect indexes and the transcriptomic change in subjects’ peripheral blood before and after treatment. We found that β CD 41-42(-TTCT)/βA was the main genotype of the subjects. The regulatory impact of CCA treatment became more evident among the subjects of genotype β CD 41-42(-TTCT)/βA. Gene ontogenesis analysis revealed that the top five molecular functions of differentially expressed genes were involved in membrane functionality and cellular structure. We further identified two consistent upregulated genes ZNF471 and THOC5 in the effective treatment group, which were engaged in Kruppel-associated box (KRAB) domain-containing zinc-finger protein...
