METHODS： Hale rats were randomly divided into four groups, namely intestinal ischemia-reperfusion group （R）, aFGF treatment group （A）, intestinal ischemia group （I）, and sham-operated control group （C）. In group I, the animals were killed after 45 min of superior mesenteric artery （SHA） occlusion. In groups R and A, the rats sustained for 45 min of SHA occlusion and were treated with normal saline （0.15 mL） and aFGF （20 μg/kg, 0.15 mL）, then sustained at various times for up to 48 h after reperfusion. In group C, SHA was separated, but without occlusion. Apoptosis in intestinal villi was determined with terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling technique （TUNEL）. Intestinal tissue samples were taken not only for RT- PCR to detect P53 and P21WAF-1 gene expression, but also for immunohistochemical analysis to detect P53 and P21WAF-1 protein expression and distribution. RESULTS： In histopathological study, ameliorated intestinal structures were observed at 2, 6, and 12 h after reperfusion in A group compared to R group. The apoptotic rates were （41.17±3.49）%, （42.83±5.23）%, and （53.33±6.92）% at 2, 6, and 12 h after reperfusion, respectively in A group, which were apparently lower than those in R group at their matched time points （50.67±6.95）%, （54.17±7.86）%, and （64.33±6.47）%, respectively, （P〈0.05））. The protein contents of P53 and P21WAF-1 were both significantly decreased in A group compared to R group （P〈0.05） at 2-12 h after reperfusion, while the mRNA levels of P53 and P21VVAF-1 in A group were obviously lower than those in R group at 6-12 h after reperfusion （P〈0.05）. CONCLUSION： P53 and P21WAF-1 protein accumulations are associated with intestinal barrier injury induced by I-R insult, while intravenous aFGF can alleviate apoptosis of rat intestinal cells by inhibiting P53 and P21WAF-1 protein expression.展开更多

Subsequently, thePhylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt), a bioinformaticssoftware package, was used to predict different pathways between the groups and to explore the potentialmechanisms by which the gut microbiota influenced the protective effect of FGF21.RESULTSThe results indicated that FGF21 notably diminished the levels of serum AMS (944.5 ± 15.9 vs 1732 ± 83.9, P < 0.01)and inflammatory factors including IL-6 (0.2400 ± 0.55 vs 1.233 ± 0.053, P < 0.01), TNF- (0.7067 ± 0.22 vs 1.433 ±0.051, P < 0.01), and IL-1β (1.377 ± 0.069 vs 0.3328 ± 0.02542, P < 0.01) in diabetic mice with AP. Moreover, notablesigns of recovery were observed in the pancreatic structure of the mice. The histologic evidence of inflammation inthe small intestine, including edema and villous damage, was significantly alleviated. FGF21 also significantlyaltered the composition of the gut microbiota, reestablishing the Bacteroidetes/Firmicutes ratio. Upon treatment withan Abx cocktail to deplete the gut microbiota, the FGF21 + Abx group showed lower levels of serum AMS (0.9328 ±0.075 vs 0.2249 ± 0.023, P < 0.01) and inflammatory factors (1.083 ± 0.12 vs 0.2799 ± 0.032, p < 0.01) than the FGF21group. Furthermore, the FGF21 + Abx group exhibited diminished injury to the pancreatic and small intestinaltissues, accompanied by a significant decrease in blood glucose levels (17.50 ± 1.1 vs 9.817 ± 0.69 mmol/L, P <0.001). These findings underscored the superior protective effects of the combination therapy involving an Abxcocktail with FGF21 over the FGF21 treatment alone in diabetic mice with AP. The gut microbiota compositionacross different groups was further characterized, and a differential expression analysis of gene functions wasundertaken using the PICRUSt2 prediction method. These findings suggested that FGF21 could potentially confertherapeutic effects on diabetic mice with AP by modulating the sulfate reduction I pathway and the superpathwayof n-acetylceramide degradation in the gut microbiota.CONCLUSION This study reveals the potential of FGF21 in improving pancreatic and intestinal damage recovery, reducing bloodglucose levels, and reshaping gut microbiota composition in diabetic mice with AP. Notably, the protective effectsof FGF21 are augmented when combined with the Abx cocktail.展开更多

[ Method ] The effects of lactose concentration, induction duration, induction starting time, and induc- tion temperature on expression of the recombinant product were compared, and the optimal condition for lactose induction was determined with IPTG induction as a control. [ Result] As an induction agent, lactose plays an ideal rele in the production of recombinant FGF21. In addition, the expression level of lactose induction product is consistent with that of IPTG induction product. Induction in a 250 rrd flask containing 50 ml of medium at A600 0.8 - 1.0 using 0.5 g/L lactose at 35 ℃ for 6 h are the optimal condition. [ Conclusion] Lactose can induce the expression of FGF21 gene and achieve ideal results. This study provides experimental basis and reference for the industrial production of FGF21.展开更多

Nonalcoholic steatohepatitis (NASH) is apparently the key link between diabetes and HCC. Recently, it is noted that the effects of FGF19 and FGF21 on metabolism suggest that endocrine fibroblast growth factors (FGFs) and their derivatives carry great potential as novel therapeutic agents for metabolic conditions. The pharmacological application of FGF21/19 holds great promise as an effective therapeutic means for treating obesity and diabetes. New insights into FGF21 and FGF19/FGFR4 signaling may also offer a novel strategy to prevent and treat the subpopulation of HCC patients with metabolic disorders.展开更多
