As intracellular fatty acid(FA) carriers,FA-binding proteins(FABPs) widely participate in the absorption,transport,and metabolism of FAs.It is a key protein in insect lipid metabolism and plays an important role in various physiological activities of insects.An FABP gene(HvFABP) was cloned from the transcriptional library of Heortia vitessoides Moore(Lepidoptera:Crambidae),and its expression patterns were determined using reverse transcription quantitative PCR(RTqPCR).Stage-and tissue-specific expression profiles indicated that HvFABP highly expressed from prepupal to adult stages and in larval midgut and adult wings.HvFABP expression may be induced through starvation,mRNA expression was downregulated at 24 and 48 h and upregulated at 72 h after starvation.Furthermore,20-hydroxyecdysone can induce the upregulation of its expression.RNA interference-mediated silencing of Hv FABP significantly inhibited HvFABP expression,resulting in delayed development,abnormal molting or lethal phenotypes,and a significantly reduced survival rate.These results indicate that HvFABP plays a key role in the molting of H.vitessoides. 展开更多

Background:Research on nutrition in early-life commonly focuses on the maturation of the intestine because the intestinal system is crucial for ensuring continued growth.To explore the importance of early nutrition regulation in animals,soy protein concentrate(SPC)was added to the early diet of broilers to investigate its effects on amino acid digestibility,intestinal development,especially intestinal microorganisms,and broiler metabolites.A total of 192 oneday-old Arbor Acres(AA)male broilers were randomly assigned to two experimental treatments with 8 replicates of 12 birds.The control group was fed a basal diet(control),and the treatment group was fed a basal diet supplemented with 12%SPC(SPC12)during the first 10 d(starter phase).From d 11 to 21(grower phase)and d 22 to 42(finisher phase),a basal diet was fed to both treatment groups.Results:SPC reduced the pH value and acid-binding capacity of the starter diet(P<0.05,d 10);SPC in the early diet enhanced the gizzard weight(P<0.05,d 10 and d 42)and the ileum weight(P<0.05,d 10)and decreased the weight and length of the jejunum(P<0.05,d 10)and the relative length of the duodenum and jejunum(P<0.05,d 10).At the same time,SPC enhanced villus height(P<0.05,d 10)and muscle thickness in the jejunum and ileum(P<0.05,d 10)and increased the number of goblet cells in the duodenum(P<0.05,d 10).Meanwhile,SPC increased the Chao1 index and the ACE index(P<0.05,d 10)and altered the composition of caecal microflora at d 10.SPC also increased the relative abundance of Alistipes,Anaerotruncus,Erysipelatoclostridium,Intestinimonas and Flavonifractor bacteria(P<0.05,d 10).At the same time,the concentrations of caecal butyric acid and total short-chain fatty acids(SCFAs)were also increased in the SPC12 group(P<0.05,d 10).Conclusions:In summary,the results showed that supplementing the starter diet of broilers with SPC has a significant effect on the early development of the intestine and the microflora. 展开更多

To ascertain the relationship between the Ala54Thr variation of FABP2 gene and general as well as regional adipose tissue depots. Subjects. 165 subjects, in which 86 were subjects with normal glucose tolerance (NGT) [age 54 45±9 80, male/female 1 05,body mass index (BMI)26 48±4 01] and 79 were subjects with non insulin dependent diabetes mellitus (NIDDM)(age 55 86±10 00,male/female 1 08,BMI 26 75±3 30). Design and measurements. An association study of FABP2 Ala54Thr variation detected by PCR/HhaI digestion with general and regional adipose tissue depots determined by BMI and magnetic resonance imaging [abdominal subcutaneous and visceral adipose tissue area (SA and VA) and femoral subcutaneous adipose tissue area (FA)]. Results. The geneotype and allele frequencies of FABP2 Ala54Thr variation in Chinese were quite close to the frequencies in American Caucasians and Pima Indians reported in the literature. Significant difference in genotype frequency distribution was observed between FA subgroups comparisons (FA≥75cm 2 versus FA<75cm 2 )in NIDDM subjects (X 2 =11 460,P=0 003),with significantly increased in Thr54 carrier[Thr54(+)]genotype frequency and Thr54 allele frequency in NIDDM subject with FA<75cm 2 (odd ratio for genotype was 4 62,X 2 =10 112,P=0 001;and for allele=2 36,X 2 =5 379,P=0 020).The FA in NIDDM Thr54(+)subgroup was significantly lower than that in subjects with NIDDM Thr54( )sugroup(61 19±21 51cm 2 versus 75 36±31 70cm 2 ,P=0 021). Stepwise regression analysis revealed that FABP2 Thr54 genotype variation was an independent factor contributing to the variation of FA in NIDDM(P=0 003). Conclusion. FABP2 is associated with regional adipose tissue depot.The decreased femoral subcutaneous adipose tissue depot in NIDDM subjects is related to FABP2 Thr54 variant. 展开更多

AIM To study the effects of different diets on intestinal microbiota and nonalcoholic fatty liver disease(NAFLD) development at the same caloric intake.METHODS Thirty male Sprague-Dawley rats were randomized into five groups(six rats each). The control diet(CON) group and free high-fat diet(FFAT) group were allowed ad libitum access to a normal chow diet and a highfat diet, respectively. The restrictive high-fat diet(RFAT) group, restrictive high-sugar diet(RSUG) group, and high-protein diet(PRO) group were fed a highfat diet, a high-sugar diet, and a high-protein diet, respectively, in an isocaloric way. All rats were killed at 12 wk. Body weight, visceral fat index(visceral fat/body weight), liver index(liver/body weight), insulin resistance, portal lipopolysaccharide(LPS), serum alanine aminotransferase(ALT), serum aspartate aminotransferase(AST), and liver triglycerides were measured. The intestinal microbiota in the different groups of rats was sequenced using high-throughput sequencing technology.RESULTS The FFAT group had higher body weight, visceral fat index, liver index, peripheral insulin resistance, portal LPS, serum ALT, serum AST, and liver triglycerides compared with all other groups(P < 0.05). Taking the same calories, the RFAT and RSUG groups demonstrated increased body weight, visceral fat index, peripheral insulin resistance and liver triglycerides compared with the PRO group(P < 0.05). The RFAT group also showed increased portal LPS compared with the PRO group(P < 0.05). Unweighted Uni Frac principal coordinates analysis of the sequencing data revealed that the intestinal microbiota structures of the CON, FFAT, RSUG and PRO groups were roughly separated away from each other. Taxon-based analysis showed that, compared with the CON group, the FFAT group had an increased abundance of Firmicutes, Roseburia and Oscillospira bacteria, a higher ratio of Firmicutes to Bacteroidetes, and a decreased abundance of Bacteroidetes, Bacteroides and Parabacteroides bacteria(P < 0.05). The RFAT group showed an increased abundance of Firmicutes and decreased abundance of Parabacteroides bacteria(P < 0.05). The RSUG group showed an increased abundance of Bacteroidetes and Sutterella bacteria, higher ratio of Bacteroidetes to Firmicutes, and a decreased abundance of Firmicutes(P < 0.05). The PRO group showed an increased abundance of Bacteroidetes, Prevotella, Oscillospira and Sutterella bacteria, and a decreased abundance of Firmicutes(P < 0.05). Compared with the FFAT group, the RFAT group had an increased abundance of Bacteroidetes, higher ratio of Bacteroidetes to Firmicutes, and decreased abundance of Firmicutes and Oscillospira bacteria(P < 0.05).CONCLUSION Compared with the high-protein diet, the NAFLDinducing effects of high-fat and high-sugar diets are independent from calories, and may be associated with changed intestinal microbiota. 展开更多

Heart fatty acid-binding protein (H-FABP) is supposed to be the most sensitive biomarker of early acute myocardial infarction (AMI). To evaluate the diagnostic value of H-FABP for AMI in the early stage, the plasma levels of H-FABP were measured by sandwich ELISA in 93 patients with suspected AMI at admission within 6 h after onset of chest pain and 69 normal healthy subjects. The plasma concentrations of cardiac troponin-I (cTnI), creatine kinase-MB (CK-MB) and myoglobin (Mb) were assayed at the same time by using corpuscle chemiluminescence for those patients. The patients were classified as AMI group (n=32) and non-AMI group (n=61) retrospectively. The diagnostic validity was evaluated in terms of sensitivity, specificity and receiver operating characteristic (ROC) curve analysis. The results showed the cutoff value of H-FABP for AMI was 16.8 ng/ml, and its diagnostic sensitivity for AMI was 64.29 % within 3 h and 84.38 % within 6 h after onset of chest pain, and the diagnostic specificity for non-AMI was 100 % within 3 h and 91.8 % within 6 h. H-FABP had higher sensitivity than that of cTnI and CK-MB at all time points (P<0.05), whereas there was no significant difference in specificity among the four markers. But the area under the ROC curve of H-FABP was significantly greater than that of cTnI, CK-MB and Mb within 3 h. These results revealed that H-FABP possessed high diagnostic sensitivity and specificity for AMI in early stage, especially within 3 h after onset of persistent angina pectoris. In conclusion, H-FABP can be used as a sensitive marker for AMI in the early stage. 展开更多
