Antibody-dependent cell-mediated cytotoxicity, a key effector function for the clinical efficacy of monoclonal antibodies, is mediated primarily through a set of closely related Fcgamma receptors with both activating and inhibitory activities. By using computational design algorithms and high-throughput screening, we have engineered a series of Fc variants(More)
Tumor necrosis factor (TNF) is a key regulator of inflammatory responses and has been implicated in many pathological conditions. We used structure-based design to engineer variant TNF proteins that rapidly form heterotrimers with native TNF to give complexes that neither bind to nor stimulate signaling through TNF receptors. Thus, TNF is inactivated by(More)
Colorectal cancer with metastases limited to the liver (liver-limited mCRC) is a distinct clinical subset characterized by possible cure with surgery. We performed high-depth sequencing of over 750 cancer-associated genes and copy number profiling in matched primary, metastasis and normal tissues to characterize genomic progression in 18 patients with(More)
Recombinant human growth hormone (hGH) is used worldwide for the treatment of pediatric hypopituitary dwarfism and in children suffering from low levels of hGH. It has limited stability in solution, and because of poor oral absorption, is administered by injection, typically several times a week. Development has therefore focused on more stable or(More)
Native TALL-1 (B-cell activation factor, BAFF; also known as BlyS) was initially described as a homotrimer, but Liu and colleagues claim that it is a 60-subunit complex on the basis of their results from X-ray crystallography and size-exclusion chromatography. They consider TALL-1 60-mers to be the biologically active form, and the arrangement of the(More)
Granulocyte-colony stimulating factor (G-CSF) is used worldwide to prevent neutropenia caused by high-dose chemotherapy. It has limited stability, strict formulation and storage requirements, and because of poor oral absorption must be administered by injection (typically daily). Thus, there is significant interest in developing analogs with improved(More)
FAT10 (HLA-F-adjacent transcript 10) is a ubiquitin-like modifier that is commonly overexpressed in various tumors. It was found to play a role in mitotic regulation through its interaction with mitotic arrest-deficient 2 (MAD2). Overexpression of FAT10 promotes tumor growth and malignancy. Here, we identified the MAD2-binding interface of FAT10 to be(More)
The key cellular regulator p53 is a common target of viral oncoproteins. However, the mechanism by which p53 transcription regulation is modulated by hepatitis B virus X protein (HBx), a transcription cofactor implicated in hepatitis B virus-associated hepatocellular carcinoma (HCC), is poorly understood. By integrating p53 chromatin immunoprecipitation(More)
Falcipain-2A, the cysteine protease of Plasmodium falciparum has been proposed as a good drug target. This study evaluated the suitability of Plasmodium berghei as the animal model and reports the first functional expression and characterization of the falcipain-2A orthologue, berghepain-2. Comparative studies revealed that the orthologues exhibited(More)
BACKGROUND The tumour suppressor p53 is a central player in transcription regulation and cell fate determination. By interacting with p53 and altering its sequence-specific binding to the response elements, the hepatitis B virus X protein (HBx) was reported to re-direct p53 regulation of some genes. RESULTS Coupling massively parallel deep sequencing with(More)
