YAP1 Recognizes Inflammatory and Mechanical Cues to Exacerbate Benign Prostatic Hyperplasia via Promoting Cell Survival and Fibrosis.

Chronic prostatic inflammation promotes cell survival and fibrosis, leading to benign prostatic hyperplasia (BPH) with aggravated urinary symptoms. It is investigated whether yes-associated protein 1 (YAP1), an organ size controller and mechanical transductor, is implicated in inflammation-induced BPH. The correlation between YAP1 expression and fibrosis in human and rat BPH specimens is analyzed.

The Expression and Function of Piezo Channels in Bladder.

The ability for bladder to perceive and analyze mechanical stimuli, such as stretch and filling, is crucial for its functions, such as urinary storage and voiding. The Piezo channel family, including Piezo1 and Piezo2, represents one of the most essential mechanosensitive ion channels in mammals and is involved in a wide array of physiological and pathological processes. It has been demonstrated in numerous investigations that Piezo channels play a key role in mechanical transduction in various types of cells in bladder by converting mechanical stimuli into biological signals.

High glucose promotes benign prostatic hyperplasia by downregulating PDK4 expression.

As men age, a growing number develop benign prostatic hyperplasia (BPH). According to previous research, diabetes may be a risk factor. Pyruvate dehydrogenase kinase 4 (PDK4) is closely related to glucose metabolism and plays a role in the onset and progression of numerous illnesses.

Cryptotanshinone modulates proliferation, apoptosis, and fibrosis through inhibiting AR and EGFR/STAT3 axis to ameliorate benign prostatic hyperplasia progression.

Benign prostatic hyperplasia (BPH) is a chronic proliferative non-tumorous disease that mainly bothers males older than 50 and significantly disturbs the quality of life. Cryptotanshinone (CTS), a herbal extract, has been proven with therapeutic effects on various diseases. However, the effects and possible mechanisms of CTS in BPH have not yet been elucidated.
