Abstract
The anticancer therapeutic effects of usnic acid (UA), a lichen secondary metabolite, have been demonstrated in vitro and in vivo. However, the mechanism underlying the anticancer effect of UA remains to be clarified. In this study, the target protein of UA was identified using a UA-linker-Affi-Gel molecule, which showed that UA binds to the 14-3-3 protein. UA binds to 14-3-3, causing the degradation of proteasomal and autophagosomal proteins. The interaction of UA with 14-3-3 isoforms modulated cell invasion, cell cycle progression, aerobic glycolysis, mitochondrial biogenesis, and the Akt/mTOR, JNK, STAT3, NF-κB, and AP-1 signaling pathways in colorectal cancer. A peptide inhibitor of 14-3-3 blocked or regressed the activity of UA and inhibited its effects. The results suggest that UA binds to 14-3-3 isoforms and suppresses cancer progression by affecting 14-3-3 targets and phosphorylated proteins.

Abstract
Signal transduction cascades efficiently transmit chemical and/or physical signals from the extracellular environment to intracellular compartments, thereby eliciting an appropriate cellular response. Most often, these signaling processes are mediated by specific protein-protein interactions involving hundreds of different receptors, enzymes, transcription factors, and signaling, adaptor and scaffolding proteins. Among them, 14-3-3 proteins are a family of highly conserved scaffolding molecules expressed in all eukaryotes, where they modulate the function of other proteins, primarily in a phosphorylation-dependent manner. Through these binding interactions, 14-3-3 proteins participate in key cellular processes, such as cell-cycle control, apoptosis, signal transduction, energy metabolism, and protein trafficking. To date, several hundreds of 14-3-3 binding partners have been identified, including protein kinases, phosphatases, receptors and transcription factors, which have been implicated in the onset of various diseases. As such, 14-3-3 proteins are promising targets for pharmaceutical interventions. However, despite intensive research into their protein-protein interactions, our understanding of the molecular mechanisms whereby 14-3-3 proteins regulate the functions of their binding partners remains insufficient. This review article provides an overview of the current state of the art of the molecular mechanisms whereby 14-3-3 proteins regulate their binding partners, focusing on recent structural studies of 14-3-3 protein complexes.

Abstract
Preeclampsia (PE) is a pregnancy disorder characterized by excessive trophoblast cell death. This study aims to explore the exact mechanism of the ubiquitination level of FUN14 domain containing 1 (FUNDC1) in mitophagy and injury in hypoxic trophoblast cells. In this study, HTR-8/SVneo trophoblast cells were cultured under normoxic and hypoxic conditions and PE mouse model was established. We found low ubiquitination level of FUNDC1 in hypoxic trophoblast cells and placenta of pregnant women with PE. Proteasome inhibitor MG-132 and protease activator MF-094 were added into HTR-8/SVneo trophoblast cells. Proteasome inhibitor MG-132 decreased FUNDC1 ubiquitination level while protease activator MF-094 increased FUNDC1 ubiquitination level. Inhibition of FUNDC1 ubiquitination promoted mitophagy and mitochondrial membrane potential (Δψm) in normoxic trophoblast cells, increased levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and decreased levels of glutathione (GSH) and superoxide dismutase (SOD). In addition, FUNDC1 ubiquitination alleviated cell injury in PE mice in vivo. In conclusion, increased FUNDC1 ubiquitination level inhibited mitophagy and Δψm changes in hypoxic trophoblast cells, and thus alleviated oxidative injury.

Abstract
Collective cell migration refers to the movement of groups of cells and collective cell behavior and relies on cell-cell communication and cell-environment interactions. Collective cell migration plays a fundamental role in many aspects of cell biology and pathology. Current protocols for studying collective cell migration either use destructive methods or are not convenient for liquid handling. Here we present a novel 3D-printed insert-array and a 3D-coculture-array for collective cell migration study in high-throughput. The fabricated insert-array is comprised of 96 cylinder shaped inserts which can be placed in each well of a 96-well plate generating watertight contact with the bottom of each well. The insert-array has high manufacturing tolerance, and the coefficient of variations of the insert diameter and circularity are 0.67% and 0.03%, respectively. Each insert generates a circular cell-free area within the well without cell damage and provides convenient access for both manual and robotic liquid handling. Using the 3D-printed insert-array, we studied the migration of human umbilical vein endothelial cells (HUVECs) under the molecular influences of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) and under the cellular influences of human mesenchymal stem cells (hMSCs) using the 3D-coculture-array. Our results show that the migration of HUVECs was dose-dependent on the VEGF and bFGF with different correlation patterns. They also generated a synergic pro-migration effect. When cocultured with hMSCs, the migration rate increased significantly while dependent on the number of hMSCs. The effects were partially blocked by VEGF inhibitor which suggests that VEGF secreted from hMSCs plays an important role in cell-to-cell communication during cell migration. The 3D-coculture-array can be manufactured at very low cost and shows higher biomolecule transport efficiency than the commercially available transwell. The calculated Z-factor is 0.66, which classifies our system as a perfect high-throughput assay. In summary, our newly developed insert-array and 3D-coculture-array provide a versatile platform to study collective cell migration in high-throughput as well as the molecular and cellular influences upon it.

Abstract
In solid cancers, invasion and metastasis account for more than 90% of mortality. However, in the current armory of anticancer therapies, a specific category of anti-invasion and antimetastatic drugs is missing. Here, we coin the term ‘migrastatics’ for drugs interfering with all modes of cancer cell invasion and metastasis, to distinguish this class from conventional cytostatic drugs, which are mainly directed against cell proliferation. We define actin polymerization and contractility as target mechanisms for migrastatics, and review candidate migrastatic drugs. Critical assessment of these antimetastatic agents is warranted, because they may define new options for the treatment of solid cancers. Local invasion and metastasis, rather than clonal proliferation, are the dominant features of solid cancer. However, a specific category of anti-invasion and antimetastatic drugs is missing for treatment of solid cancer We propose the term ‘migrastatics’ for drugs interfering with all modes of cancer cell invasiveness and, consequently, with their ability to metastasize (e.g., inhibiting not only local invasion, but also extravasation and metastatic colonization). In solid cancer, drug resistance is the main cause of treatment failure, and is attributed to mutations of the target. Since targeting the cause, although academically desirable, may be futile, a pragmatic and near-term option is to move downstream, to common denominators of cell migration and/or invasion, such as actin polymerization and actomyosin-mediated contractility.

Abstract
![]()
Direct
interactions between proteins are essential for the regulation
of their functions in biological pathways. Targeting the complex network
of protein–protein interactions (PPIs) has now been widely
recognized as an attractive means to therapeutically intervene in
disease states. Even though this is a challenging endeavor and PPIs
have long been regarded as “undruggable” targets, the
last two decades have seen an increasing number of successful examples
of PPI modulators, resulting in growing interest in this field. PPI
modulation requires novel approaches and the integrated efforts of
multiple disciplines to be a fruitful strategy. This perspective focuses
on the hub-protein 14-3-3, which has several hundred identified protein
interaction partners, and is therefore involved in a wide range of
cellular processes and diseases. Here, we aim to provide an integrated
overview of the approaches explored for the modulation of 14-3-3 PPIs
and review the examples resulting from these efforts in both inhibiting
and stabilizing specific 14-3-3 protein complexes by small molecules,
peptide mimetics, and natural products.
