[Will a glaucoma drug revolutionize the treatment of androgenetic alopecia? On drug repurposing, when the side effect becomes a desired therapeutic outcome].

Prostaglandins are hormones found in almost all mammalian tissues. As signaling molecules, they play a key role in the regulation of many physiological processes, including hair growth cycle. The article describes the history of the discovery of prostaglandins, including the work of Professor Ryszard Gryglewski – the discoverer of prostacyclin.

β-escin activates ALDH and prevents cigarette smoke-induced cell death.

Background: The tobacco use is one of the biggest public health threats worldwide. Cigarette smoke contains over 7000 chemicals among other aldehydes, regarded as priority toxicants. β-escin (a mixture of triterpenoid saponins extracted from the Aesculus hippocastanum.

New, Low-Molecular Weight Chemical Compounds Inhibiting Biological Activity of Interleukin 15.

Chronic overproduction of IL-15 contributes to the pathogenesis of numerous inflammatory and autoimmune disorders. Experimental methods used to reduce the cytokine activity show promise as potential therapeutic approaches to modify IL-15 signaling and alleviate the development and progression of IL-15-related diseases. We previously demonstrated that an efficient reduction of IL-15 activity can be obtained by selective blocking of the specific, high affinity subunit alpha of the IL-15 receptor (IL-15Rα) with small-molecule inhibitors.

Beneficial effects of β-escin on muscle regeneration in rat model of skeletal muscle injury.

Background: Recent advancements in understanding β-escin action provide basis for new therapeutic claims for the drug. β-escin-evoked attenuation of NF-κB-dependent signaling, increase in MMP-14 and decrease in COUP-TFII content and a rise in cholesterol biosynthesis could be beneficial in alleviating muscle-damaging processes.

Purpose: The aim of this study was to investigate the effect of β-escin on skeletal muscle regeneration.
