HIF-1α knockdown leads to reduced lytic replication of KSHV.

Abstract

<p><b>(A)</b> mRNA levels of RTA, vIL-6, and ORF26 (a late lytic gene) of KSHV in BCBL-1 cells measured by RT-qPCR. Error bars represent standard deviation from at least 3 experiments. (<b>B)</b> Western blot showing protein levels of intracellular RTA, vIL6, and β-actin in the cell lysates as well as secreted vIL6 in the supernatant after 48 hours in normoxia (N) or hypoxia (H). (<b>C)</b> Protein levels of ORF45 in concentrated virus particles released in the supernatants after 72 hours. *Unspecific band. Western blots were done on lysates from three independent experiments and representative blots are shown.</p
