Project description:To compare the efficacy of tegafur/uracil (UFT) plus folinate calcium (leucovorin: LV) administered orally and UFT plus Krestin (PSK) administered orally enrolling patients with pTNM stage IIB or III colorectal cancer as subjects in a multicenter collaborative randomized open-label comparative controlled study and consequently to determine the usefulness of the above regimens as adjuvant therapy after surgery.

Randomized Phase III Adjuvant Study for Stage III Colorectal Cancer

Project description:A randomized controlled study is conducted on patients with histological stage III colorectal cancer assigned to postoperative adjuvant therapy of uracil-tegafur plus leucovorin (UFT+LV), UFT+LV / UFT, or UFT+LV+PSK / UFT+PSK. The usefulness of the three regimens was evaluated by comparing the disease-free survival rate, overall survival rate, incidence and severity of adverse event, and quality of life.

A role of PSK-CPK28-GS2 signalling in optimizing growth and defence in tomato

Project description:Phytosulfokine (PSK) is a plant pentapeptide hormone that fulfills a wide range of functions. Although it has been frequently reported to function in the inverse regulation of growth and defence in response to (hemi)biotrophic pathogens, the mechanism involved remains largely unknown. Using tomato (Solanum lycopersicum) and Pseudomonas syringae pv. tomato (Pst) DC3000 pathogen as a system, we present compelling evidence that the tomato PSK receptor PSKR1 interacts with the calcium-dependent protein kinase CPK28, which phosphorylates the key enzyme of nitrogen assimilation glutamine synthetase GS2 at two sites (S334 and S360 sites). These post translational modifications uncouple the two PSK-induced effects on defence responses and on growth regulation, respectively. The discovery of these sites will inform breeding strategies designed to optimize the growth-defence balance. The concept that such peptide hormones can regulate plant growth and resistance in a compatible manner is attractive, not least because crop yields and fitness can be optimized simultaneously in global climate-change era.

Prediction of sensitivity of rectal cancer cells in response to preoperative chemoradiotherapy by DNA microarray analysis of gene expression profiles.

Project description:Samples were prospectively collected during colonoscopic examination from 46 rectal cancer patients before starting preoperative chemoradiotherapy. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for prediction of the response to radiotherapy in rectal cancer. Specimens from 46 rectal cancer patients who approved to receive preoperative chemoradiotherapy were studied. We prospectively collected biopsy specimens during colonoscopic examination from rectal cancer before starting preoperative chemoradiotherapy. Specimens from tumors were snap-frozen in liquid nitrogen and stored at -80 C until use. Paralleled tumor specimens were formalin fixed and paraffin embedded for histologic examination and other specimens were used for RNA extraction. RNA was extracted from tumor tissue using frozen samples. The patients provided written, informed consent to the collection of specimens, and the local Ethics Committee approved the study protocol. All patients received a total dose of 50.4 Gy of radiation, UFT(300-500mg/day) and LV (75mg/day) and underwent standardized curative resection, following an interval of 4 weeks after chemoradiotherapy.

Next Generation Sequencing Facilitates Quantitative Analysis of PSKγ1ox and control Transcriptomes

Project description:Phytosulfokine-α (PSK-α), a sulfated pentapeptide hormone with the sequence YIYTQ, plays important roles in many aspects of plant growth and development. In this study, we identified a pair of putative precursor genes in soybean, GmPSKγ1 and -2, encoding a PSK-like peptide: PSK-γ. Similar to PSK-α in amino acid composition, the sequence of PSK-γ is YVYTQ, and the tyrosines undergo sulfonylation. Treatment of Arabidopsis seedlings with synthetic sulfated PSK-γ significantly enhanced root elongation, indicating that PSK-γ might be a functional analog of PSK-α. Expression pattern analysis revealed that the two GmPSKγ genes, especially GmPSKγ1, are primarily expressed in developing soybean seeds. Heterologous expression of GmPSKγ1 under the control of a seed-specific promoter markedly increased seed size and weight in Arabidopsis, and this promoting effect of PSK-γ on seed growth was further confirmed in transgenic tobacco constitutively expressing GmPSKγ1. Cytological analysis of transgenic Arabidopsis seeds revealed that PSK-γ promotes seed growth by inducing embryo cell expansion. In addition, transcriptome analysis of GmPSKγ1-expressing Arabidopsis seeds suggested that PSK-γ signaling may regulate cell wall loosening to promote cell expansion. Overall, our results shed light on the mechanism by which PSK-γ promotes seed growth, paving the way for the use of this new peptide for biotechnological improvement of crop seed/grain size and yield.
