Dietary fibre, irradiation and bladder tumour in tumour-bearing mice.

Mouse bladder tumour flank xenografts were implanted into C57BL/6 mice when starting low (0.2% cellulose) and high fibre (5% psyllium, 5% psyllium plus 10% resistant starch, 5% psyllium plus 10% inulin) diets and irradiated with 6Gy ionising radiation when they reached 100mm³ (N=60). 16S rRNA sequencing was used for gut microbiota analysis.

在开始饲喂低纤维（0.2%纤维素）与高纤维膳食（包含5%洋车前子、5%洋车前子+10%抗性淀粉、5%洋车前子+10%菊粉三种亚型）的同时，将小鼠膀胱肿瘤侧腹皮下移植瘤移植至C57BL/6小鼠体内；待移植瘤体积达到100mm³时，对实验小鼠给予6Gy电离辐射照射，本实验总样本量N=60。采用16S rRNA测序技术开展肠道菌群分析。
