The present study was to explore the Ile requirement of piglets fed 18%crude protein(CP)*** hundred and fifty 28-day-old Duroc×Landrace×Yorkshire piglets(8.37±1.92 kg)were randomly divided into 5 dietary treatments(10 piglets per replicate,5 barrows and 5 gilts per replicate)with 45%,50%,55%,60%,65%standardized ileal digestible(SID)Ile-to-Lys ratios,and the SID Lys was formulated to1.19%.The experimental design consisted of two phases(d 1 to 14 and d 15 to 28).Results showed that average daily gain(ADG)had a tendency to quadratically increase as the SID Ile-to-Lys ratio increased(P=0.09),and the optimum SID Ile-to-Lys ratios required to maximize ADG were 48.33%and 54.63%for broken-line linear model and quadratic polynomial model,*** SID Ile-to-Lys ratios had no significant effects on average daily feed intake and gain-to-feed *** matter(P<0.01),CP(P=0.01),ether extract(P=0.04),gross energy(P<0.01)and organic matter(P<0.01)digestibility increased *** total cholesterol levels decreased linearly(P=0.01)and quadratically(P<0.01);aspartate aminotransferase(P<0.01),interleukin-1β(P=0.01),and tumor necrosis factor-a(P<0.01)levels decreased quadratically;immunoglobulin G(P=0.03)and immunoglobulin M(P=0.01)concentrations increased *** Ser levels decreased linearly(P<0.01)and quadratically(P=0.01);Glu(P=0.02),Arg(P=0.05),and Thr(P=0.03)levels decreased quadratically;Gly(P<0.01)and Leu(P=0.01)levels decreased linearly;Ile(P<0.01)concentration increased *** villus height(P<0.01)and villus height to crypt depth ratio(P<0.01)increased *** deficiency or excess of Ile decreased short chain fatty acid-producing bacteria abundance and increased pathogenic bacteria ***,taking ADG as the effect index,the optimum SID Ile-to-Lys ratios of piglets offered 18%CP diets were 48.33%and 54.63%based on two different statistical models,respectively,and the deficiency or excess of lle negative

Dear Editor,Plant cell walls are complex and dynamic structures that are mainly composed of polysaccharide polymers such as cellulose,hemicellulose,and pectin,in addition to substantial amounts of the non-saccharide polymer lignin(McFarlane et al.,2014;German et al.,2023).The components of cell walls are interconnected in various ways to form a complex,multilayered network structure(Wen et al.,2023).

OBJECTIVE:To unmask the underlying mechanisms of Yisui granule(益髓颗粒,YSG)for the treatment of Myelodysplastic syndromes(MDS).METHODS:Our study used an SKM-1 mouse xenograft model of MDS to explore the anti-tumor potential of YSG and its safety,assess its effect on overall survival(OS),and evaluate whether its mechanism is associated with the demethylation of the secreted frizzled related protein 5(s FRP5)gene and suppressing Wnt/β-catenin *** amplicon sequencing was applied to detect the level of methylation of the s FRP5 gene;western blotting,immunofluorescence staining,and real-time Polymerase Chain Reaction were performed to detect DNA methyltransferase 1(DNMT1),s FRP5,and other Wnt/β-catenin pathway-related m RNA and protein ***:The results showed that high-dosage YSG exerted an anti-tumor effect similar to that of decitabine,improved OS,and reduced long-term adverse effects in the long ***,YSG reduced the expression of DNMT1 methyltransferase,decreased the methylation,and increased the expression of the Wnt/β-catenin pathway antagonist-s ***,components of the Wnt/β-catenin pathway,including Wnt3a,β-catenin,c-Myc,and cyclin D1,were down-regulated in response to YSG,suggesting that YSG could treat MDS by demethylating the s FRP5 gene and suppressing the Wnt/β-catenin ***:Our findings demonstrated that YSG could be used alone or in combination with decitabine to improve outcomes in the MDS animal model,providing an alternative solution for treating MDS.
