background:We hypothesized that supplementation of nursery and grower pig diets with coconut oil in the absence of antibiotics would yield maintenance of glucose homeostasis,growth performance,and immune function similar to what is achieved with nursery and grower pig diets containing *** received the same base treatment diets from d24(weaning)to d71 of age and had blood and fecal samples collected on d24,d31,d45 and d71 for measurement of whole blood glucose,serum insulin,cortisol and cytokines,and fecal *** had weekly weights and daily feed consumption measured throughout the *** were euthanized at d71 and subcutaneous fat and ileal contents were collected for assessment for fatty acids and microbiome,*** treatments consisted of 2%soybean oil plus antibiotics(AbX;n=22),2%soybean oil without antibiotics(NAbX;n=22),and 2%coconut oil without antibiotics(COC;n=22).Statistical analysis examined the effect of diet within each timepoint using a repeated measures ***:Pigs fed COC diet had decreased serum insulin levels,maintained feed intake,feed conversion and weight gain,and,based on serum cytokines and fecal microbiome,were immunologically similar to AbX-fed ***,NAbX-fed pigs performed similarly to the AbX-fed pigs in all parameters except for serum ***,there was no difference in the incidence of diarrhea between any of the diet ***:This study demonstrates that dietary antibiotics are not necessary to maintain growth performance in nursery and grower ***,dietary antibiotics appear to modulate circulating cytokine *** coconut oil is neither harmful nor helpful to growth performance or immune function in nursery and grower pigs but does modulate serum insulin ***,while coconut oil fed at 2%by weight is a suitable substitute for dietary antibiotics,this study suggests that no substitute for dietary antibiotics is needed at all.

在一项新的研究中，来自美国德州大学MD安德森癌症中心的研究人员利用患者源性肿瘤异种移植（patient—derived tumorxenograft,PDx）和模式小鼠开展一系列临床前实验，鉴定出一种门卫蛋白（gatekee Perprotein）阻止胰腺癌细胞转化为一种极具侵袭性的细胞类型，并且也发现剔除这种门卫蛋白的疗法能够阻止这些癌细胞。这些发现有助为携带这种进展迅速的治疗抵抗性的胰腺癌细胞亚群的患者开发出潜在的疗法。
