Gene Expression of Prox-1 and Hif-1a in Primo Vessels Inside Lymph Vessels of the Rabbit.
Abstract
The gene expression of Prox-1 and Hif-1a for the isolated primo vessels (PVs) and composite lymphatic vessels (LVs) containing PVs (LVs\xa0+\xa0PVs) was investigated by RNA-sequencing (Seq) and quantitative polymerase chain reaction (qRT-PCR) analysis. RNA-Seq on the passed 10 samples on RNA-QC for two experimental groups with PVs and PVs\xa0+\xa0LVs proceeded to the library construction stage automatically and analyzed differentially expressed genes (DEGs). From the real-time qRT-PCR analysis data, we found the marker genes of Prox-1 and Hif-1a were enriched and decreased in an isolated PVs compared to LVs, respectively. Based on mRNA transcriptional data, Prox-1 and Hif-1a were increased and decreased in PVs compared to LVs\xa0+\xa0PVs under lipopolysaccharide (LPS) treatment and relieved by acupuncture electric stimulation (AES), respectively. This finding indicates that high and low levels of Prox-1 and Hif-1a may be involved in the function of PVs and that pathophysiological and physiological condition could progress into inflamed lymphatic endothelial cells expanding the PV within the LV.
