The absorbance was measured at 450 nm utilizing a microplate reader. Reverse transcriptionpolymerase chain reaction (RTPCR) of apoptoticrelated gene expression inside the colon tissue. Total RNA was isolated from the colon tissue using TRIzol reagent (Invitrogen Life Technologies, Carlsbad, CA, USA), as outlined by the manufacturer’s guidelines. The RNA was digested with RNasefree DNase (Roche Diagnostics, Basel, Switzerland) for 15 min at 37 and purified utilizing a RNeasy kit (Qiagen, Hilden, Germany), in accordance with the manufacturer’s guidelines. cDNA was synthesized from two total RNA by way of incubation at 37 for l h with avian myeloblastosis reverse transcriptase (GE Healthcare, Amersham, UK) and random hexanucleotides, based on the manufacturer’s instructions.
