Mode of action PROT_D_UP
Description for ‘mode of action’:the ‘mode of action’ for signature is composed of three parts: A_B_C. A describes the level at which the corresponding signature changes, it may contain the following values: TRAN(translation), PROT(protein), CE(cell), METH(methylation), AC(acetylation), PHOS(phosphorylation), MU(mutation), SNP(single nucleotide polymorphism), GLYC(glycosylation) and PATH(pathway). B describes the corresponding signature in which cancer immunotherapy condition group has changed, it may contain the following values: R (immunotherapy response group), NR(immunotherapy non-response group), D (Immunotherapy group), ND (No immunotherapy group). C describes the change detail (specific direction) of the corresponding signature, it may contain the following values: UP (High gene/protein expression or increased cellular abundance or enhanced epigenetic modification), DN (Low gene/protein expression or reduced cellular abundance or attenuated epigenetic modifications), LOSS (deletion mutation), GAIN (gain mutation),Other. For example, the search/browse detail result for CD274 was “PROT_R_UP”, it can be interpreted that the protein level of CD274 was upregulated in immunotherapy response individuals.
Experimental mouse model
Description To further investigate the immune responses that were induced by the combination of tasquinimod with Anti-PD-L1intheMBT-2 tumor model, we isolated splenocytesfrom tumor-bearing miceand subjected them to stimulation with PMA/ionomycin for 4 h. An increase in the intracellular expression of IL-2, IFN-γand TNF-α gated onCD8+ was found in the combination group as comparedto control. CD8+ producing IFN-γwas also increasedin the tumors treated with Anti-PD-L1alone. In addition, high amounts of IFN-γintothe serum of mice treated with the combination therapieswere foundas comparedto single agents orto the control group.These data all together indicated that the combination of tasquinimod with Anti-PD-L1 treatment activated the adaptive immune system to exert a cytotoxic immune response.
