IFNG and neoplasm: Moreover, lactate dehydrogenase (LDH) release assays further indicated that the inhibition of piRNA‐137463 increased endogenous LDH release by tumor cells (Figure 2I,J; Figure S2F,G, Supporting Information), accompanied by a remarkable increase in the level of IFN‐γ, an indicator of T cell killing efficiency (Figure 2K; Figure S2H, Supporting Information), suggesting an increase in T‐cell mediated cell death.
