The chloride intracellular channel (CLIC) protein family consists of six members in humans. CLICs are unique due to their metamorphic property, displaying both soluble and integral membrane forms. The transmembrane conformation was shown to give rise to ion-channel activity in vitro. In recent years, CLICs were implicated in a growing number of physiological processes in various organ systems and associated with distinct disease states. Indeed, the founding member of the family, CLIC5, was shown to be involved in hereditary deafness and various types of cancer. Nevertheless, the natural interactants and endogenous ligands of CLIC5 have not been discovered yet. ⋯ Using the approach we developed, large libraries of small molecules can be screened efficiently to identify novel CLIC5 interactants. Considering the participation of CLIC5 in various physiological and pathological processes, uncovering ligands that inhibit or activate CLIC5 may provide tools to modulate its activity and possibly to ameliorate CLIC5-related pathologies in the future.

Statin-induced myalgia is defined as muscle pain without elevation of serum creatine phosphokinase levels and is a well-known complaint among statin users. Chronic pain syndromes affect a high percentage of the population. These pain syndromes may confound the reports of statin-induced myalgia. ⋯ A significant percentage of patients diagnosed with statin myalgia fulfilled the diagnostic criteria for fibromyalgia depression or anxiety disorder. Detection of these patients and treatment of their primary pain disorders or psychiatric illnesses has the potential to prevent unnecessary cessation of effective statin therapy.
