In Wilson disease (WD), functional loss of ATPase copper-transporting β (ATP7B) impairs biliary copper excretion, leading to excessive copper accumulation in the liver and fulminant hepatitis. Current US Food and Drug Administration- and European Medicines Agency-approved pharmacological treatments usually fail to restore copper homeostasis in pati...

In-depth analysis of the mitochondrial proteome can be greatly improved by analyzing isolated mitochondria instead of whole cells. However, isolation of sufficient amounts of mitochondria from cell culture has proven to be notoriously difficult due to small sample size. Thus, we have developed a reproducible, controllable, and highly customizable m...

The increasingly aged human population (mainly in developed countries) represents a significant scientific achievement and privilege associated with medical, social, and economic progress. However, it also poses several challenges to national health and social care systems. The uncoupling of biological evolution with the vast and fast technical pro...

Liver cancers, including hepatocellular carcinoma (HCC), are the second most lethal cancers worldwide and novel therapeutic strategies are still highly needed. Recently, the endolysosomal cation channel TRPML1 has gained focus in cancer research representing an interesting novel target. We utilized the recently developed isoform-selective TRPML1 ac...

Augmenter of liver regeneration (ALR) is a critical multi-isoform protein with its longer isoform, located in the mitochondrial intermembrane space, being part of the mitochondrial disulfide relay system (DRS). Upregulation of ALR was observed in multiple forms of cancer, among them hepatocellular carcinoma (HCC). To shed light into ALR function in...

Isolation of mitochondria is a crucial method for examining molecular details of this organelle’s manifold functions. Historically, mitochondrial isolations required large amounts of sample material which impeded their isolation from cultured cells. We have therefore developed a method allowing for controlled and reproducible isolation of intact an...

Developmental neurotoxicity (DNT) testing performed in rats is resource-intensive (costs, time, animals) and bears the issue of species extrapolation. Thus, reliable alternative human-based approaches are needed for predicting neurodevelopmental toxicity. Human induced pluripotent stem cells (hiPSCs) represent a basis for an alternative method poss...
