No difference emerged in the mTOR transcript levels between CTRL (62.07±16) tissues and tissues obtained from patients with CH (53.3±30), CIRR (56.2±30) and HCC (51.6±37), but CTRL showed significantly higher mTOR transcript levels than PM (30.6±18; q = 0.04) and M (25.8±18; q = 0.008). This evidence concerns the gene MTOR and cyclic hematopoiesis.
