Conventional chemotherapy is still frequently used. Programmed cell death 5 (PDCD5) enhances apoptosis of various tumor cells triggered by certain stimuli and is lowly expressed in leukemic cells from chronic myelogenous leukemia patients. Here, we describe for the first time that recombinant human PDCD5 protein (rhPDCD5) in combination with chemotherapy(More)
In this study, we describe a method for highly specific enrichment of phosphopeptides with multifunctional chitosan-glycidyl methacrylate (GMA)-iminodiacetic acid (IDA)-Fe (III) nanospheres for direct analysis by matrix-assisted laser desorption-ionization mass spectrometry (MALDI-MS). This is the first time that chitosan has been used to create nanospheres(More)
Chemokine-like factor 1(CKLF1) is a newly cloned cytokine with three RNA splicing isoforms. It has chemotactic activities on leukocytes and plays an important role in skeletal muscle regeneration. Here we have isolated two rat homologues of human chemokine-like factors by expressed sequence tag assembly, which are designated as rat chemokine-like factor 1(More)
Chemokine-like factor 1 (CKLF1) is a novel cytokine first cloned from U937 cells. It contains different splicing forms and has chemotactic effects on a wide spectrum of cells both in vitro and in vivo; it can also stimulate the regeneration of skeletal muscle cells in vivo, but the mechanism remains unclear. To probe the myogenesis function of CKLF2, which(More)
Apoptosis is a genetically determined cell suicidal program that plays critical roles in many physiological and pathological processes. In this study, we report the cloning and characterization of a novel human gene, nuclear apoptosis-inducing factor 1 (NAIF1), overexpression of which induces apoptosis in cells. Human NAIF1 is located on chromosome 9q34.11(More)
B12 belongs to the coumarin class of compounds that have been shown to have various physiological and pharmacological activities including anti-inflammatory, antibacterial, and antioxidant. In the present study, we characterised the neuroprotective effects of B12 against H2O2-induced neuronal cell damage in SH-SY5Y cells. Protein expression profiling in(More)
FAM176A (family with sequence similarity 176 member A) is a novel molecule related to programmed cell death. A decreased expression of FAM176A has been found in several types of human tumors in including lung cancers. In the present study, we investigated the biological activities of FAM176A on the human non-small cell lung cancer cell line H1299 cells. We(More)
In this study, we describe characterization of the human plasma proteome based on analysis with multifunctional chitosan-GMA-IDA-Cu(II) nanospheres. Chitosan-GMA-IDA-Cu(II) nanospheres with diameters of 20 to 100 nm have unique properties due to multifunctional chemical moieties, high surface area, high capacity, good dispersibility in buffer solution as(More)
Given that the proteasome is essential for multiple cellular processes by degrading diverse regulatory proteins, inhibition of the proteasome has emerged as an attractive target for anti-cancer therapy. YSY01A is a novel small molecule compound targeting the proteasome. The compound was found to suppress viability of MCF-7 cells and cause limited cell(More)
MARCH2 (membrane-associated RING-CH protein 2), an E3 ubiquitin ligase, is mainly associated with the vesicle trafficking. In the present study, for the first time, we demonstrated that MARCH2 negatively regulates autophagy. Our data indicated that overexpression of MARCH2 impaired autophagy, as evidenced by attenuated levels of LC3B-II and impaired(More)
