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: 1.6 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: 2.2 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: 0.3 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: 0.00058 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: 0.33 SJR: 0.345 SNIP: 0.46 CiteScore™:: 2.5 H-Index: 67

RESUMO

Androgens are important not only for the development and function of the normal prostate gland, but also for the maintenance of prostate cancer (PCa) cells. The biological function of androgens is exerted by activation of the transcriptional activity of the androgen receptor (AR). The function of the AR in the prostate is largely dependent on AR protein levels and structural integrity of the protein and other transcription activation factors. Based upon the clinical findings that androgen ablation therapy-resistant PCa still expresses AR and the androgen-regulated gene, prostate-specific antigen, a concept is developing that the androgen receptor is critical for androgen-refractory prostate cancer cells. Indeed, because of the alterations detected in the AR gene, many noncognate activators, including estrogen, progesterone, peptide growth factors, and cytokines, are able to induce transactivation of the AR under androgen-depleted conditions. Also, transactivational activity of the AR is often modulated by crosstalk between the AR and other signaling pathways in cancerous prostatic cells. Dysregulation of AR function in prostate cancer results in an abnormal profile of AR-regulated genes, which include cell cycle regulators, transcription factors, and those proteins important for cell survival, lipogenesis, and secretion. Thus in this review we will evaluate the significance of the AR in the development and progression of prostate cancer.
