Reverse-phase liquid chromatography/electrospray ion trap mass spectrometry (LC-ESI-MSn) was established for identification of the molecular species of lactosylceramides. Lactosylceramides derived from porcine blood cells were separated on a CapcellPak C8 column using a mixture of methanol and 1 mM ammonium formate from the C16 to C26 fatty acyl chains(More)
Chronic inflammation promotes the progression of diabetic nephropathy (DN). However, the role of TNF-α remains unclear. The objectives of the present study were to examine whether TNF-α inhibition with a soluble TNF receptor (TNFR)2 fusion protein, i.e., etanercept (ETN), improves the early stage of DN in the type 2 diabetic model of the KK-A(y) mouse and(More)
We developed a strategy for determination and quantification of glycosyl flavonoids using liquid chromatography-triple quadrupole mass spectrometry with neutral loss scan at 15 and 30eV collision energy in the positive ion mode. The fragmentation patterns of glycosyl flavonoids at 15 and 30eV showed that fragmentation of sugar moiety depended on the type of(More)
Screening for prostate cancer remains unsatisfactory. Recent studies have examined the cancer diagnostic/prognostic values of various acute phase proteins, such as haptoglobin. We describe here a novel method of surface plasmon resonance (SPR) based on multi-sequential analysis with SNA-1, AAL, and PHA-L(4) lectin, to estimate the glycosylation status of(More)
Metastasis is still a major issue in cancer, and the discovery of biomarkers predicting metastatic capacity is essential for the development of better therapeutic strategies for treating lung adenocarcinoma. By using a proteomic approach, we aimed to identify novel predictors for lymph node metastasis in lung adenocarcinoma. Two-dimensional sodium dodecyl(More)
Laminin α1 (LAMA1), a subunit of the laminin-111 basement membrane component, has been implicated in various biological functions in vivo and in vitro. Although LAMA1 is present in kidney, its roles in the kidney are unknown because of early embryonic lethality. Herein, we used a viable conditional knockout mouse model with a deletion of Lama1 in the(More)
Occurrences of high values in patients with benign prostate disease and low values in patients with highly suspicious cancer have diminished the trustworthiness of prostate-specific antigen as an early diagnostic marker of prostate cancer. In the search for other complimentary markers, we focused on serum IgG from patients with prostate diseases as well as(More)
Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by the aberrant expression of several growth-regulating, oncogenic effectors. Exportin 1 (XPO1) mediates the nucleocytoplasmic transport of numerous molecules including oncogenic growth-regulating factors, RNAs, and ribosomal subunits. In MCL cells, the small molecule KPT-185 blocks(More)
ADAM28 (disintegrin and metalloproteinase 28), which was originally reported to be lymphocyte-specific, is over-expressed by carcinoma cells and plays a key role in cell proliferation and progression in human lung and breast carcinomas. We studied ADAM28 expression in human normal tissues and examined its biological function. By using antibodies specific to(More)
