MicroRNAs (miRNAs) are potential regulators that contribute to the pathogenesis of cancer. Microarray technologies have been widely used to characterize aberrant miRNA expression patterns in cancer. Nevertheless, the miRNAs expression signatures identified for a same cancer differs among laboratories due to the cancer heterogeneity. In addition, how the(More)
ß-Nerve growth factor (NGF) is expressed in spermatogenic cells and has testosterone-downregu-lated low-affinity receptors on Sertoli cells suggesting a paracrine role in the regulation of spermatogenesis. An analysis of the stage-specific expression of NGF and its low affinity receptor during the cycle of the seminiferous epithelium in the rat revealed NGF(More)
Tumor necrosis factor-alpha (TNF-a) promotes cell survival during spermatogenesis, and this effect can be blocked by infliximab, a TNF-a antagonist Abstract Objective: Tumor necrosis factor-alpha (TNF-a) has been shown to inhibit germ cell death in human seminiferous epithelium. In the present study, we wanted to explore the effects of TNF-a in the rat(More)
BACKGROUND Individually submitted prostatic needle biopsies are recommended by most guidelines because of their potential advantage in terms of core quality. However, unspecified bilateral biopsies are commonly submitted in many centers. The length of the core is the key quality indicator of prostate biopsies. Because there are few recent publications(More)
