Abstract

Benign prostatic hyperplasia (BPH) and benign prostatic enlargement (BPE) are among the most frequent medical disorders of elderly men and cause a number of annoying symptoms of the lower urinary tract (LUTS), leading to reduced quality of life and severe complications, including acute urinary retention. Nodular overgrowth of the epithelium and in particular the fibromuscular tissue is observed in the transition zone and periurethral areas. In particular, functional and phenotypic transdifferentiation of fibroblasts into myofibroblasts is a hallmark of the tissue remodeling in the benign hyperplastic prostate. BPH/BPE have a complex pathophysiology with a multitude of endocrine and local factors involved. Two risk factors, namely aging and circulating androgens, contribute significantly to risk of BPH/BPE. One of the primary initiating mechanisms appears to be a consequence of age-related changes in systemic sex steroid hormone levels accompanied by alterations in local androgen metabolism. This results in the disruption of the delicate balance of interacting growth factor signaling pathways and stromal/epithelial interactions generating a growth promoting and tissue remodeling microenvironment that leads to an increase in pros...Continue Reading

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
