Yet, recent accumulating evidence implicates FK506-binding proteins (FKBPs), a type of peptidylprolyl cis-trans isomerase (PPIase) proteins, in ABC transporter regulation. In this perspective article, we summarize current knowledge on ABC transporter regulation by FKBPs, which seems to be conserved over kingdoms and ABC subfamilies. We uncover striking functional similarities but also differences between regulatory FKBP-ABC modules in plants and mammals. We dissect a PPIase- and HSP90-dependent and independent impact of FKBPs on ABC biogenesis and transport activity. We propose and discuss a putative new mode of transient ABC transporter regulation by cis-trans isomerization of X-prolyl bonds.Melasma is a common disorder of hyperpigmentation that presents a therapeutic challenge for clinical dermatologists. The pathogenesis is complex, but previous studies have demonstrated vascular proliferation is a key factor in the development of the classic hyperpigmented patches. Studies have revealed reduction of erythema by oral tranexamic acid; however, there has been no direct comparison to placebo. This 24-week randomised placebo-controlled trial demonstrates oral tranexamic acid may improve erythema in melasma. This mechanism of action may be the reason for the success of tranexamic acid in complex and difficult to treat melasma.Alcoholic cardiomyopathy (ACM) resulting from chronic alcohol misuse is one of the main contributors leading to heart failure and cardiovascular mortality. Fibroblast growth factor 21 (FGF21) is a well-established cardioprotective factor. We aimed to study the role of FGF21 in experimentally induced models and clinical affected patients with cardiac damage due
