The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

Краткое описание

Hypoxia inducible factor-1α (HIF-lα) is a central regulator of tumor survival and metastasis, responsible for metabolic adaptation to hypoxic conditions and promotion of angiogenesis. It has been also shown to respond to non-hypoxic stimuli, such as growth factors and moderate oxidative stress. We examined the protein levels of HIF-lα in A549 human lung cells exposed to the typical carcinogen benzo[a]pyrene (B[a]P). Our results revealed that B[a]P, at low, non-cytotoxic concentrations, induced a transient increase of nuclear HIF-lα and its target, GLUT1. HIF-lα upregulation was partly mediated by Akt kinase and coincided with increased nuclear levels of the redox-sensitive marker, nuclear factor erythroid 2-related factor-2 (NrF-2). B[a]P-induced HIF-lα was also detected during serum depletion or treatment with the hypoxia-mimicking agent, CoCl2. In addition, exposure of A549 cells to B[a]P containing diesel exhaust particles enhanced HIF-lα accumulation, probably due to the presence of additional carcinogenic compounds. B[a]P-induced increase of HIF-lα was further confirmed in normal rat and human lung fibroblasts. Our findings indicate that HIF-lα stimulation may act as an early and sensitive marker of exposure to low, non-cytotoxic concentrations of B[a]P and/or other carcinogens.
