Ferroportin (Fpn) is an essential mammalian iron transporter that is negatively regulated by the hormone hepcidin. Our current molecular understanding of Fpn-mediated iron efflux and regulation is limited due to a lack of biochemical, biophysical and high-resolution structural studies. A critical step towards understanding the transport mechanism o...

Leukemic stem cells (LSCs) are a very rare cell population that result in the development of acute myeloid leukemia (AML). The selective targeting of drivers in LSCs with small molecule inhibitors holds promise for treatment of AML. Recently, we reported the identification of inhibitors of the histone lysine demethylase JMJD1C that preferentially k...

Deoxyhypusine synthase transfers an aminobutyl moiety from spermidine to the eukaryotic translation initiation factor 5A (eIF5A) in the first step of eIF5A activation. This exclusive post-translational modification is conserved in all eukaryotes. Activated eIF5A has been shown to be essential for cell proliferation and viability. Recent reports hav...

The role of surface loops in mediating communication through residue networks is still a relatively poorly understood part in the study of cold adaptation of enzymes, especially in terms of their quaternary interactions. Alkaline phosphatase (AP) from the psychrophilic marine bacterium Vibrio splendidus (VAP) is characterized by an analogous large ...

The calcitonin receptor (CTR) has a large extracellular domain (ECD) with multiple N-glycosylation sites. An asparagine (Asn)-linked N-acetylglucosamine (GlcNAc) of CTR ECD N130 was previously reported to enhance peptide hormone binding affinity for CTR ECD. CTR forms a complex with an accessory protein RAMP, and the RAMP:CTR complex gains affinity...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related fatalities worldwide. Identification of second-line therapies for patients with progressive HCC is urgently required as the use of sorafenib and/or regorafenib remains unsatisfactory. Imatinib, a small-molecule kinase inhibitor, is used to treat certain types of cancer, and...

Leupeptin is a naturally occurring inhibitor of various proteases, in particular serine proteases. Following its discovery, the inhibitory properties of several other peptidyl argininals have been studied. The specificity of leupeptin is most likely due to the Leu-Leu-Argininal sequence, and its C-terminal aldehyde group has been suggested to enhan...

Colorectal cancer was the third most commonly diagnosed malignant tumor and the fourth leading cause of cancer deaths worldwide in 2012. A human colorectal cancer cell line, RCM-1, was established from a colon cancer tissue diagnosed as a well-differentiated rectum adenocarcinoma. RCM-1 cells spontaneously form 'domes' (formerly designated 'ducts')...

Osteoarthritis (OA) is a chronic joint disease characterized by articular cartilage degeneration and secondary osteogenesis. It has been previously demonstrated that the CCAL1 locus is the gene encoding tumor necrosis factor receptor superfamily member 11B (TNFRSF11B). The purpose of this study was to demonstrate the role of CCAL1 in OA progression...

Micro-exons are a set of ultrashort exons with lengths ≤ 51 nucleotides. Our previous study revealed that micro-exons were enriched in AP2 domains and K-box domains, which are crucial components of AP2/ERF (APETALA2/ethylene-responsive element-binding protein) and MADS-box (an acronym of MCM1, AGAMOUS, DEFICIENS and SRF) genes, respectively. In thi...
