In conclusion, counteraction against the suppression by tumor cells on CD71 expression, cell proliferation, FasL expression in lymphocytes after induction with PHA denotes a counteraction against the suppression by tumor cells on the function of lymphocytes, which is important to facilitate cancer immunotherapy, therefore, Gl-PS showing the effects of counteraction against the suppression induced by B16F10-CS on CD71 expression, cell proliferation, as well as FasL expression after induction with PHA, fully or partially, indicated the potential of Gl-PS to facilitate cancer immunotherapy. This evidence concerns the gene TFRC and cancer.
