ABSTRACT: Fatty acids are unique macromolecules as they act as biological modulators of transcription factors and regulate their own metabolism by controlling the activity or abundance of transcription factors of fatty acid metabolism either by RNA processing and RNA stability. Peroxisome Proliferator Activated Receptor (PPAR-γ) and Sterol Regulatory Element Binding Protein (SREBP-1c) are transcription factors expressed primarily in adipose tissue. We have studied the relation of fatty acid including trans fatty acid assessed in adipose tissue with the transcription factors. Adipose tissue was collected from 50 healthy subjects undergoing elective abdominal surgery. Fatty acid was assessed in the tissue by gas chromatography. The expressions of PPARγ and SREBP-1c were studied by real time RT-PCR. The expressions of PPARγ and SREBP1c were significantly correlated (r = 0.4 p
