MicroRNAs (miRNAs) are a class of single-stranded and non-coding endogenous RNAs with 18-25 nucleotides in length. By binding to the complementary sequences in the 3’untranslated region (3’UTR) of protein coding genes， miRNAs regulate posttranscriptionally the mRNA expression of target genes and enzymes involved in various biological processes. The application of high-throughput sequencing， bioinformatics analysis， and novel detection methods has high-lighted promising roles of miRNAs as both novel biomarkers for tumor diagnosis and critical regulators involved in almost all stages of carcinogenesis including cancer initiation， promotion and progression. Epigallocatechin-3-gallate (EGCG)， the most investigated active catechin in green tea， has been linked to various health-promoting benefits including chemoprevention and treatment of cancers. In this review， we first present a brief description of EGCG and its major metabolic pathway. It is followed by reviewing the roles of EGCG in the modulation of oncogenic and tumor suppressing miRNAs in some common cancers. These findings suggest that the capacity of EGCG to regulate expression of specific miRNAs provides insights of its new mechanisms of action underlying its chemopreventive and potential beneficial activities against various cancers.

This research was to assess the dietary copper(Cu)requirement of broiler chickens fed a practical cornsoybean meal diet during 22—42 d of age.A total of 288 numbered Arbor Acres male broilers at 22 d of age were randomly allotted 6 treatments with 8 replicate cages(6 broilers per cage)per *** were fed a Cu-unsupplemented corn-soybean meal basal diet(control,containing 7.36 mg Cu/kg)or the basal diet added with 3,6,9,12,or 15 mg Cu/kg from CuSO_(4)·5H_(2)O for 21 ***,asymptotic and broken-line models were fitted and the best fitted models were selected to determine dietary Cu *** results revealed that the contents of Cu in serum and liver,m RNA expression levels of Cu-and zinc-containing superoxide dismutase(CuZnSOD)in liver and monoamine oxidase b(MAO B)in heart,as well as protein expression level of CuZnSOD in liver were affected(P<0.05)by supplemental Cu levels,and the above indices varied linearly and quadratically(P<0.05)with increasing Cu *** Cu requirements assessed according to the best fitted broken-line models(P<0.05)of the above indexes were 10.45—13.81 mg/*** was concluded that mRNA expression levels of CuZnSOD in liver and MAO B in heart,as well as liver CuZnSOD protein expression level were new specific sensitive biomarkers for estimating dietary Cu requirements,and the dietary Cu requirement was recommended to be 14 mg/kg to support Cu metabolic needs related to key Cucontaining enzymes in broilers fed the corn-soybean meal diet during 22—42 d of age,which was higher than the dietary Cu requirement(8 mg/kg)for broilers at the corresponding stage suggested by the Chinese Feeding Standard of Chicken.

Background Intestinal barrier is a dynamic interface between the body and the ingested food components, however, dietary components or xenobiotics could compromise intestinal integrity, causing health risks to the host. Gossypol, a toxic component in cottonseed meal(CSM), caused intestinal injury in fish or other monogastric animals. It has been demonstrated that probiotics administration benefits the intestinal barrier integrity, but the efficacy of probiotics in maintaining intestinal health when the host is exposed to gossypol remains unclear. Here, a strain(YC) affiliated to Pediococcus pentosaceus was isolated from the gut of Nile tilapia(Oreochromis niloticus) and its potential to repair gossypol-induced intestinal damage was *** A total of 270 Nile tilapia(2.20 ± 0.02 g) were allotted in 3 groups with 3 tanks each and fed with 3 diets including CON(control diet), GOS(control diet containing 300 mg/kg gossypol) and GP(control diet containing 300 mg/kg gossypol and 10^(8) colony-forming unit(CFU)/g P. pentosaceus YC), respectively. After 10 weeks, addition of P. pentosaceus YC restored growth retardation and intestinal injury induced by gossypol in Nile tilapia. Transcriptome analysis and si RNA interference experiments demonstrated that NOD-like receptors(NLR) family caspase recruitment domain(CARD) domain containing 3(Nlrc3) inhibition might promote intestinal stem cell(ISC) proliferation, as well as maintaining gut barrier integrity. 16S r RNA sequencing and gas chromatography-mass spectrometry(GC-MS) revealed that addition of P. pentosaceus YC altered the composition of gut microbiota and increased the content of propionate in fish gut. In vitro studies on propionate's function demonstrated that it suppressed nlrc3 expression and promoted wound healing in Caco-2 cell *** The present study reveals that P. pentosaceus YC has the capacity to ameliorate intestinal barrier injury by modulating gut microbiota composition and elevating

Hematopoietic stem and progenitor cells(HsPCs)are a subset population of multi-potent cells with self-renewal capability and differentiation into all lineages of blood cells(Zhang and Liu,2024).HSPCs arise from the ventral wall of embryonic dorsal aorta,the hemogenic endothelium in the aorta-gonad-mesonephros(AGM)region,tightly controlled by epigenetic,transcriptional,and signaling networks(Wu and Hirschi,2021).However,how developmental hemogenic endothelium performs cell fate surveillances during HSPC emergence and efficiently eliminates them to avoid abnormal hematopoiesisremainselusive.
