Li-Mei Chen, Karl X Chai
The epithelial extracellular membrane-associated serine proteases matriptase, hepsin, and prostasin are proteolytic modifying enzymes of the extracellular domain (ECD) of the epidermal growth factor receptor (EGFR). Matriptase also cleaves the ECD of the vascular endothelial growth factor receptor 2 (VEGFR2) and the angiopoietin receptor Tie2. In this study we tested the hypothesis that these serine proteases may cleave the ECD of additional receptor tyrosine kinases (RTKs). We co-expressed the proteases in an epithelial cell line with Her2, Her3, Her4, insulin receptor (INSR), insulin-like growth factor I receptor (IGF-1R), the platelet-derived growth factor receptors (PDGFRs) α and β, or nerve growth factor receptor A (TrkA)...

The homeobox-containing gene HOXB7 plays an important role in the pathogenesis and progression of many cancers, yet its role in hepatocellular carcinoma (HCC) remains unclear. This study comprehensively analyzed the expression and clinical significance of HOXB7 in HCC and explored its potential mechanism in tumor progression. We found HOXB7 was highly expressed in HCC cell lines with highly metastatic potential and cancerous tissues from patients with tumor recurrence. The abilities of proliferation, migration, and invasion were notably decreased by depletion of HOXB7, and were enhanced by its enforced expression in vitro...

Intrinsically disordered proteins (IDPs) or intrinsically disordered regions have not fixed tertiary structure, but play key roles in signal regulation, molecule recognition, and drug target. However it is difficult to study the structure and function of IDPs by traditional experimental methods because of their diverse conformations. Limitations of current generic protein force fields and solvent models were reported in the previous simulations of IDPs. We have also explored to overcome these limitations by developing ff99IDPs and ff14IDPs force fields to correct the dihedral distribution for eight disordered promoting residues often observed in IDPs and found encouraging improvements...

Oxidative stress plays a key role in the pathogenesis of age-related macular degeneration (AMD), a leading cause of severe visual loss and blindness in the aging population which lacks any effective treatments currently. In this study, artemisinin, a well-known anti-malarial drug was found to suppress hydrogen peroxide (H2O2)-induced cell death in retinal neuronal RGC-5 cells. Artemisinin, in the therapeutically relevant dosage, concentration-dependently attenuated the accumulation of intracellular reactive oxygen species (ROS), increased mitochondrial mitochondrial membrane potential and decreased cell apoptosis in RGC-5 cells induced by H2O2...

RAS protein activator like 2 (RASAL2) has been reported to be dysregulated in various types of cancer. It has previously been demonstrated that RASAL2 is hypomethylated in hepatocellular carcinoma (HCC). However, the expression pattern of RASAL2 and its potential role in HCC remain to be elucidated. The present study demonstrated that the expression of RASAL2 was upregulated in HCC tissues, compared with in normal liver tissues, by using immunohistochemistry. In addition, Cell Counting Kit-8 assay and invasion assay revealed that knockdown of RASAL2 inhibited the growth and invasion of HCC cells...

Tubular epithelial‑myofibroblast transdifferentiation (TEMT) is important in the development of chronic renal failure. The present study investigated whether hepatocyte growth factor (HGF) inhibits TEMT, and whether this function may be associated with the inhibition of angiotensin II (AngII) and the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway. Human HK‑2 kidney proximal tubular cells were divided into 4 groups and treated with AngII (1x10‑6 M), HGF (8x10‑3 M), AngII plus HGF or control conditions, followed by an assessment of apoptosis induction and the expression levels of α‑smooth muscle actin (α‑SMA), which is a marker of TEMT...

Accumulative evidence has shown the adverse effects of a geomagnetic field shielded condition, so called a hypomagnetic field (HMF), on the metabolic processes and oxidative stress in animals and cells. However, the underlying mechanism remains unclear. In this study, we evaluate the role of HMF on the regulation of cellular reactive oxygen species (ROS) in human neuroblastoma SH-SY5Y cells. We found that HMF exposure led to ROS decrease, and that restoring the decrease by additional H2O2 rescued the HMF-enhanced cell proliferation...
