Mode of action TRAN_NR_DOWN
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 clinical trail
Description IFNG was among the genes that most significantly influenced the outcome of the melanoma patients treated with pembrolizumab. With a median follow up of 12.4 (95% CI 7.3–18.0) months, median progression-free survival was 1.9 months (95% CI 0.0–5.1) and 5.0 (95% CI 1.5–14.1) months for patients with low and high IFNG mRNA, respectively (p= 0.0099), (HR for dis-ease progression, 3.77; 95% CI 1.23–11.16; p=0.0164). Univariate analy-sis revealed that low IFNG mRNA expression and elevated lactate dehydrogenase (LDH) levels were significantly associated with shorter progres-sion-free survival. Paradoxically, low Rantes mRNA expression was also significantly associated with shorter progression-free survival. However, in the Cox’s regression model, only LDH levels remained a significant predictor of progression-free survival (HR for disease progres-sion, 3.13; 95% CI 1.04–9.42; p= 0.0419; Table 5). There was a trend for IFNG levels to be asso-ciated with progression-free survival (HR for dis-ease progression, 3.29; 95% CI 0.83–13.08; p=0.0910)
