A mass spectrometry-based methodology has been developed to study changes in core-fucosylation of serum ceruloplasmin that are site-specific between cirrhosis and hepatocellular carcinoma (HCC). The serum samples studied for these changes were from patients affected by cirrhosis or HCC with different etiologies, including alcohol, hepatitis B virus, or(More)
Pancreatic cancer is a lethal disease where specific early detection biomarkers would be very valuable to improve outcomes in patients. Many previous studies have compared biosamples from pancreatic cancer patients with healthy controls to find potential biomarkers. However, a range of related disease conditions can influence the performance of these(More)
An important characteristic of arbuscular mycorrhizal (AM) symbiosis is the transfer of phosphate (Pi) from AM fungi to plants, and this transfer is facilitated by plasma membrane-spanning phosphate transporter (PT) proteins. Five Nicotiana tabacum PT genes (NtPT), members of Pht1 family, express in the root. However, the ways these genes contribute to the(More)
Single amino acid variations are highly associated with many human diseases. The direct detection of peptides containing single amino acid variants (SAAVs) derived from nonsynonymous single nucleotide polymorphisms (SNPs) in serum can provide unique opportunities for SAAV associated biomarker discovery. In the present study, an isobaric labeling(More)
A specific, sensitive, and reliable high performance liquid chromatography with fluorescence detection (HPLC-FLD) was first optimized and then used in the simultaneous quantification of bergapten, imperatorin, notopterol, and isoimperatorin in rat plasma using osthole as the internal standard. Liquid-liquid extraction with ethyl acetate was employed in(More)
Thy-1 (CD90) has been shown to be a potential marker for several different types of cancer. However, reports on CD90 expression in pancreatic intraepithelial neoplasia (PanIN) lesions are still limited where PanINs are the most important precursor lesion of pancreatic ductal adenocarcinoma (PDAC). Herein, we investigate candidate markers for PanIN lesions(More)
An important characteristic of arbuscular mycorrhizal (AM) symbiosis is the transfer of phosphate from AM fungi to plants. This transfer is facilitated by mycorrhiza-inducible phosphate transporter proteins. Lysophosphatidylcholine (LPC) stimulates mycorrhiza-inducible phosphate transporter gene expression. This study aims to detect the pattern of five(More)
Flavonoids and isoflavonoids are secondary metabolites in plants. With the goal of obtaining isoflavonoids from a wide range of plants, a few key studies have proven that isoflavonoids can be produced in non-leguminous plants by transgenic engineering. Many earlier studies investigate genistein biosynthesis in leaves and petals of isoflavone synthase (IFS)(More)
SYMRK is a plant receptor-like kinase with a role in root endosymbiosis. Heterologous expression of SYMRK from non-legumes can complement the loss-of-function effects of the mutant symrk in legumes. However, it is unclear whether the development of arbuscular mycorrhiza (AM) is affected along with the enhanced expression of SYMRK. In the present study, the(More)
