Motile sperm domain containing 2 (MOSPD2) is a single-pass membrane protein to which until recently little function had been ascribed. Although its mammalian homologs have been identified, the status of the mospd2 gene in lower vertebrates is still unknown. In

Hypoxia frequently occurs in solid tumors, hepatocellular carcinoma included. Hypoxia-inducible factors (HIFs) upregulated in hypoxia can induce various downstream target genes to resist hypoxia stress, resulting in tumor growth, angiogenesis and metastasis in vivo. Therefore, hypoxia associated genes are usually

NF-κB signalling is crucial for cellular responses to inflammation but is also associated with the hypoxia response. NF-κB and hypoxia inducible factor (HIF) transcription factors possess an intense molecular crosstalk. Although it is known that HIF-1α modulates NF-κB transcriptional response

Sphingolipids have important functions as structural components of cells but they also function as signaling molecules regulating different cellular processes such as apoptosis, cell proliferation, cell migration, cell division and inflammation. Hence, a tight regulation of the sphingolipid homeostasis is
