A STT3A-dependent PD-L1 glycosylation modification mediated by GMPS drives tumor immune evasion in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a malignant tumor characterized by rapid progression. To explore the regulatory mechanism of rapid tumor growth and metastasis, we conducted proteomic and scRNA-Seq analyses on advanced HCC tissues and identified a significant molecule, guanine monophosphate synthase (GMPS), closely associated with the immune evasion in HCC. We analyzed the immune microenvironment characteristics remodeled by GMPS using scRNA-Seq and found GMPS induced tumor immune evasion in HCC by impairing the tumor-killing function of CD8  T cells.

Human leukocyte antigen DR alpha inhibits renal cell carcinoma progression by promoting the polarization of M2 macrophages to M1 via the NF-κB pathway.

Human leukocyte antigen DR alpha (HLA-DRA) is recognized for its inhibitory effect on the progression of clear cell renal cell carcinoma (ccRCC); high HLA-DRA expression levels are positively correlated with improved prognosis in patients with ccRCC. In this study, we evaluated HLA-DRA expression in ccRCCs, its effects on tumor-associated macrophage recruitment, and the influence of polarization. Clinical cohort analyses revealed that elevated HLA-DRA expression in ccRCC cells was correlated with enhanced tumor infiltration by M1-type macrophages.

M2 macrophage-derived exosomes promote cell proliferation, migration and EMT of non-small cell lung cancer by secreting miR-155-5p.

Tumor-associated macrophages (TAMs) are a type of highly plastic immune cells in the tumor microenvironment (TME), which can be classified into two main phenotypes: classical activated M1 macrophages and alternatively activated M2 macrophages. As previously reported, M2-polarized TAMs play critical role in promoting the progression of non-small cell lung cancer (NSCLC) via secreting exosomes, but the detailed mechanisms are still largely unknown. In the present study, the THP-1 monocytes were sequentially induced into M0 and M2-polarized macrophages, and the exosomes were obtained from M0 (M0-exos) and M2 (M2-exos) polarized macrophages, respectively, and co-cultured with NSCLC cells (H1299 and A549) to establish the exosomes-cell co-culture system in vitro.
