By continually driving the expression of key target genes, these oncogenic click here transcription factors play a central role in tumor pathogenesis. One such transcription factor is the cAMP-regulatory element-binding protein (CREB), which can be activated through phosphorylation by

a number of kinases, including Akt, p90Rsk, protein kinase A, and calcium/calmodulin-dependent kinases and regulates genes whose deregulated expression promotes oncogenesis, including cyclins, Bcl-2 family members, and Egr-1. CREB is overexpressed and constitutively phosphorylated in a number of forms of human cancer, including acute myeloid leukemia (AML) and non-small cell lung cancer, and appears to play a direct role in disease pathogenesis and prognosis. Although transcription factors have not been a central focus of drug development, recent advances suggest that CREB and other such proteins may be worthwhile targets for cancer therapy.”
“Purpose: To investigate the effect of voiding position on uroflowmetric variables and postvoid residual urine (PVR) volume in healthy adult men without lower urinary tract symptoms (LUTS). Materials and Methods: Men without LUTS were enrolled. Participants were asked to report to the urodynamic suite with comfortably full bladder for uroflowmetry. Each participant performed six voids into digital uroflowmeter (Solar Silver, Medical Measurement System, The Netherlands), all on separate

occasions, twice in each of the standing, sitting, and squatting down positions. JNK inhibitor PVR was measured using transabdominal buy DZNeP ultrasound (Siemens (R)). Results: Total 72 participants were enrolled and 61 completed the study; their mean (+/- SD) age was 26.6 +/- 6.9 years. All of them but one was accustomed to void in standing and squatting positions. The mean maximal flow rates (Q(max)) and average flow rates (Q(ave)) were significantly lower in sitting position, than standing and squatting positions (Q(max): 19.8 +/- 7.4 vs. 23.8 +/- 7.7 and 24.4 +/- 8.1 ml/sec, respectively; P = 0.0001. Q(ave): 11.2 +/- 4.5 vs. 13.9 +/- 4.5, and 13.8 +/-

5.1 ml/sec, respectively; P = 0.0001). The corresponding values of voiding time were significantly higher 38.6 +/- 20.7 sec vs. 28.3 +/- 15.3 and 30.6 +/- 18.1 sec, respectively; P = 0.0001). The latter two positions were statistically similar in voiding characteristics. Voided volumes and PVR were statistically similar among all the three positions. Conclusion: Uroflow parameters were higher in standing and squatting positions compared to sitting in individuals not accustomed to void in sitting position. Therefore, uroflowmetry should not be performed in a position the individual is not familiar with. Neurourol. Urodynam. 29:413-417, 2010. (C) 2009 Wiley-Liss, Inc.”
