High level of PRMT6 predicted poor outcomes of gastric cancer patients and inhibition of CD8+ T cell infiltration. PRMT6 promoted proliferation of CD8+ T cells and enhanced its tumor killing ability. Moreover, PRMT6 upregulated ANXA1 and promoted ANXA1 protein stability. ANXA1 overexpression suppressed the proliferation of CD8+ T cells and promoted tumor cell survival. PRMT6 functions as an oncogene in gastric cancer. PRMT6-mediated protein stability inhibits the infiltration of CD8+ T cells, resulting in immune evasion of gastric cancer.

Protein expression was detected by western blot. Histone crotonylation was performed using in vitro histone crotonylation assay. functional analysis was performed using CCCK-8 and flow cytometry assay. Xenografting assay was conducted to further verify the roles of SLC7A2 in TNBC. The expression of CD8A was detected using immunohistochemistry. SLC7A2 was downregulated in TNBC tumors. Low levels of SLC7A2 were associated with advanced stages and lymph node metastasis. SLC7A2 expression was positive correlated with CD8A. SLC7A2-mediated lysine catabolism drove the activation of CD8+ T cells. Moreover, SLC7A2 promoted the histone crotonylationvia upregulating ACOX1 and downregulated CDYL. SLC7A2 promoted the interaction between ACOX1 and TCF1, resulting the proliferation of CD8+ T cells. Additionally, overexpression of SLC7A2 activated CD8+ T cells and enhanced the chemosensitivity of anti-PD-1 therapies in vivo. SLC7A2 may function as an anti-tumor gene in TNBC via activating anti-tumor immunity.

In conclusion, SIAH1 exacerbated the progression of human inflammatory cardiomyopathy via inducing the ubiquitination of IκB-α and activation of NF-κB signaling.

In a mouse model, LPCAT3 mRNA and protein expression were found to be suppressed. Furthermore, in an in vitro model, the enrichment level of LPCAT3 mRNA was inhibited by a specific m6A antibody through si-METTL3. Si-METTL3 also reduced the stability of LPCAT3 mRNA in the in vitro model. The inhibition of LPCAT3 was found to exacerbate osteoarthritis in the mouse model. Additionally, LPCAT3 was shown to reduce inflammation in the in vitro model. It was also observed that LPCAT3 reduced chondrocyte ferroptosis by inhibiting mitochondrial damage. LPCAT3 protein was found to interact with ACSL4 protein, and its up-regulation suppressed ACSL4 expression in the in vitro model.
