The transcription of Hypoxia-inducible factors (hif-1, hif-2) during normal development of Beluga sturgeon (Huso huso Linnaeus, 1758)
In the present study, the levels of the hypoxia-inducible factors (hif-1, hif-2) transcripts were evaluated during development of an ancient fish species, Beluga sturgeon (Huso huso) in a normal oxygen environment. The transcripts of hif-1, hif-2 were detected in all developmental time-points of H. huso from embryos to juvenile fish. Changes in normalized hif-1, hif-2 mRNA expression by using t...
متن کاملKSHV Reactivation from Latency Requires Pim-1 and Pim-3 Kinases to Inactivate the Latency-Associated Nuclear Antigen LANA
Host signal-transduction pathways are intimately involved in the switch between latency and productive infection of herpes viruses. As with other herpes viruses, infection by Kaposi's sarcoma herpesvirus (KSHV) displays these two phases. During latency only few viral genes are expressed, while in the productive infection the virus is reactivated with initiation of extensive viral DNA replicatio...
متن کاملHypoxia Inducible Factor (HIF)-1 Coordinates Induction of Toll-Like Receptors TLR2 and TLR6 during Hypoxia
BACKGROUND During acute infection and inflammation, dramatic shifts in tissue metabolism are typical, thereby resulting in profound tissue hypoxia. Therefore, we pursued the hypothesis, that tissue hypoxia may influence innate immune responses by transcriptional modulation of Toll-like receptor (TLRs) expression and function. METHODOLOGY/PRINCIPAL FINDINGS We gained first insight from transcr...
متن کاملA Unique SUMO-2-Interacting Motif within LANA Is Essential for KSHV Latency
Kaposi's sarcoma-associated herpesvirus (KSHV) stabilizes hypoxia-inducible factor α (HIF-1α) during latent infection, and HIF-1α reactivates lytic replication under hypoxic stress. However, the mechanism utilized by KSHV to block lytic reactivation with the accumulation of HIF-1α in latency remains unclear. Here, we report that LANA encoded by KSHV contains a unique SUMO-interacting motif (LAN...
متن کاملHypoxia Promotes Glycogen Accumulation through Hypoxia Inducible Factor (HIF)-Mediated Induction of Glycogen Synthase 1
When oxygen becomes limiting, cells reduce mitochondrial respiration and increase ATP production through anaerobic fermentation of glucose. The Hypoxia Inducible Factors (HIFs) play a key role in this metabolic shift by regulating the transcription of key enzymes of glucose metabolism. Here we show that oxygen regulates the expression of the muscle glycogen synthase (GYS1). Hypoxic GYS1 inducti...
