Polysaccharides extracted from Himematsutake, the fruiting body of Agaricus blazei Murill with hot water were fractionated and purified by ethanol precipitation, ion-exchange chromatography, gel-filtration, affinity chromatography, etc. A total of 17 polysaccharide samples thus obtained were given an antitumor activity test (Sarcoma 180/mice up. p.o. method) and traces of their activities through the fractionation and purification processes were found.FI0-a-/J, FA-l-a-a, FA-l-a-/J, and FA-2-b-/?, were obtained as water soluble polysaccharides fractions having great antitumor activities.Analyses of physico-chemical properties and IR-and NMR-spectra of these active fractions showed that their main components were:

Expression quantitative trait locus (eQTL) analyses have enabled us to predict the function of disease susceptibility SNPs. However, eQTL for the effector memory T cells (TEM) located in the lamina propria mononuclear cells (LPMCs), which play an important role in Crohn’s disease (CD), are not yet available. Thus, we conducted RNA sequencing and eQTL analyses of TEM cells located in the LPMCs from IBD patients (n = 20). Genome-wide association study (GWAS) was performed using genotyping data of 713 Japanese CD patients and 2,063 controls. We compared the results of GWAS and eQTL of TEM, and also performed a transcriptome-wide association study using eQTL from Genotype Tissue Expression project. By eQTL analyses of TEM, correlations of possible candidates were confirmed in 22,632 pairs and 2,463 genes. Among these candidates, 19 SNPs which showed significant correlation with tenascin-XA (TNXA) expression were significantly associated with CD in GWAS. By TWAS, TNFSF15 (FDR = 1.35e-13) in whole blood, ERV3-1 (FDR = 2.18e-2) in lymphocytes, and ZNF713 (FDR = 3.04e-2) in the sigmoid colon was significantly associated with CD. By conducting integration analyses using GWAS and eQTL data, we confirmed multiple gene transcripts are involved in the development of CD.
