Experimental Protocol


Distal colon tissues from Sprague Dawley rats fed a variety of diets (see summary) were removed from RNAlater stabilisation reagent (Sigma, Australia) they had been stored in,, placed in 1 ml of TRIzolĀ® Reagent (Invitrogen, Australia) and homogenised usingbeads (mix of 2.5 mm glass and 0.1 - 1.0 mm diameter silicon-zirconian beads) in a MiniBeadbeater-8 (BioSpec Products Inc., USA). Total RNA was extracted (using TRIzolĀ® Reagent manufacturer's instructions) and further purified using RNAeasy mini spin columns (QIAGEN, Australia) with a DNase on-column digestion as per manufacturer's instructions.RNA integrity was checked using a Bioanalyzer 2100 (Agilent Technologies, USA) andquantified using a NanoDropĀ® ND-1000 Spectrophotometer (Thermo Fisher Scientific, USA). RNA samples with insufficinet quality and quantity were not assayed. The numbers of rats arrayed from each diet were as follows: CON, 5;LAMS, 7; HAMS, 8; HAMSB, 9; LAW, 6; HAW , 8. This gives a total of 43 arrays.
