Timothy J Hark et al.
Cell systems, 12(2), 141-158 (2020-12-17)
Compromised protein homeostasis underlies accumulation of plaques and tangles in Alzheimer's disease (AD). To observe protein turnover at early stages of amyloid beta (Aβ) proteotoxicity, we performed pulse-chase proteomics on mouse brains in three genetic models of AD that knock
Jan Kristoff et al.
EBioMedicine, 43, 295-306 (2019-04-07)
Despite the success of antiretroviral therapy (ART), latent HIV-1 continues to persist in a long-lived population of resting memory CD4+ T cells within those who are infected. Finding a safe and effective means to induce latency reversal (LR) during ART
Fei Huang et al.
Experimental cell research, 374(1), 94-103 (2018-11-21)
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
Laura D'Ignazio et al.
International journal of molecular sciences, 21(8) (2020-04-30)
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
Wei Jiang et al.
Molecular immunology, 119, 8-17 (2020-01-14)
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
Shamroop Kumar Mallela et al.
Biochimica et biophysica acta. Molecular and cell biology of lipids, 1864(12), 158517-158517 (2019-09-06)
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
Griet Van Zeebroeck et al.
Nature chemical biology, 5(1), 45-52 (2008-12-09)
Transporter-related nutrient sensors, called transceptors, mediate nutrient activation of signaling pathways through the plasma membrane. The mechanism of action of transporting and nontransporting transceptors is unknown. We have screened 319 amino acid analogs to identify compounds that act on Gap1
