Among miRNAs, which were positively associated with PLA2R1 expression in this study, hsa-miR-23b and −154 exerted suppressing effects in different cancers in vitro and in vivo [ 53– 53].
In summary, the current study showed that the Met kinase inhibitor BMS-777607, but not the anti-HGF neutralizing antibody, exerted suppressing effects on c-Met-associated cellular functions in PC-3 cells that express constitutively activated c-Met.
Mir-218 exerts suppressing function to NPC by down-regulating survivin expression and SLIT2-BOBO1 pathway [ 20], and miR-26a acts the similar function for inhibiting cell growth and tumorigenesis through repression of EZH2miR [ 21].
Whereas a central action by leptin has been shown to be critical to its metabolic control of lipid metabolism [21], [30], it remains to be completely clarified whether leptin exerts its suppressing effects upon the lipogenic program also through autonomous peripheral mechanisms, or whether the peripheral STAT3 activation is essentially involved in mediating leptin's liporegulatory actions.
As is well known, miRNAs exert function through suppressing the expression of their target genes.
It should be noted, however that BRB [ 91, 92], similar as metformin [ 93- 95], was shown to exert anticancer properties, suppressing growth and/or sensitizing cancer cells to various other anticancer modalities.
Preimmunization of mice with Ad7 evidently suppressed EGFP-specific humoral immune responses elicited by Ad3/H7, and did not exert suppressive effects on Ad3/H3.
Thirdly, antibodies against growth factor receptors also exert growth suppressing effects via the immune system [27].
The role of BMPs in cancer is somewhat unclear, but BMP-9 and -10 have been reported to exert tumor suppressing activities in both breast and prostate cancer.
IDO inhibition would have a promoting effect on colon tumorigenesis through intratumoral inflammation enhancement, but would also exert a suppressing effect by enhancing the anti-tumor immune response.
