PD-L1-mediated immune evasion in triple-negative breast cancer is linked to the loss of ZNF652. Cell Rep 2023; 42:113343. [PMID: 37906592 DOI: 10.1016/j.celrep.2023.113343] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 08/01/2023] [Accepted: 10/11/2023] [Indexed: 11/02/2023] Open
Abstract
The intrinsic regulation of programmed death ligand-1 (PD-L1) expression remains unclear. Here, we report that zinc-finger protein 652 (ZNF652) is a potent transcription repressor of PD-L1. ZNF652 frequently experiences loss of heterozygosity (LOH) in various cancers. Higher LOH rate and lack of estrogen-inducible transcription lead to suppressed expression of ZNF652 in triple-negative breast cancer (TNBC). Mechanistically, ZNF652 is physically associated with the NuRD transcription co-repressor complex to repress a cohort of genes, including PD-L1. Overexpression of ZNF652 inhibits PD-L1 transcription, whereas depletion of ZNF652 upregulates PD-L1. Loss of ZNF652 in TNBC unleashes PD-L1-mediated immune evasion both in vitro and in vivo. Significantly, ZNF652 expression is progressively lost during breast cancer progression, and a low ZNF652 level is correlated with elevated PD-L1 expression, less infiltrated CD8+ T cells, and poor prognosis in TNBC. Our study provides insights into PD-L1 regulation and supports the pursuit of ZNF652 as a potential biomarker and drug target for breast cancer immunotherapy.

Abstract
OBJECTIVE To investigate the expression of ZNF652 in breast cancer tissues and cells and explore its role in breast cancer cell proliferation, invasion and migration. METHODS We exploited the data from the TCGA database to analyze the differential expression of ZNF652 in breast cancer tissues and adjacent tissues and the correlations of ZNF652 expression with the clinicopathological characteristics of breast cancer patients including molecular subtypes, pathological types, TNM stages and clinical stages. RT-qPCR and Western blotting were used to detect the expression of ZNF652 in 5 breast cancer cell lines including MCF-7, MDA-MB-231, SK-BR-3, UACC-812 and BT-474. Using a lentivirus system and siRNA technique, we assessed the effects of ZNF652 over-expression and knockdown on proliferation, colony forming ability, migration and invasion of breast cancer cells with CCK-8 assay, clonogenic assay, Transwell assay and wound healing assay. The subcellular localization of ZNF652 in 293T cells was determined using immunofluorescence assay. RESULTS ZNF652 was significantly up-regulated in breast cancer tissues (P < 0.001). In breast cancer tissues of different molecular types, ZNF652 was down-regulated in TNBC breast cancer tissues but increased in HER2+, Luminal A and Luminal B breast cancer tissues (P < 0.01 or 0.001). The expression of ZNF652 was significantly higher in breast cancer tissues of all pathological types except for mucinous carcinoma than in the adjacent tissues (P < 0.05). The high expression of ZNF652 was closely related to distant metastasis and malignancy of breast cancer (P < 0.01 or 0.001). The mRNA and protein expression levels of ZNF652 was significantly higher in the 5 breast cancer cell lines than in normal breast cells (P < 0.05 or 0.001). Overexpression of ZNF652 promoted the proliferation, invasion and migration of breast cancer cells, while ZNF652 knockdown produced the opposite effects (P < 0.05). Immunofluorescence assay identified subcellular localization of ZNF652 in the nuclei of 293T cells. CONCLUSIONS ZNF652 is highly expressed in breast cancer tissues and cells to promote the development and progression of breast cancer and may serve as a potential molecular target for diagnosis and treatment of the malignancy.

Abstract
A germline mutation in cancer predisposing genes is known to increase the risk of more than one tumor type. In order to find loci associated with many types of cancer, a genome-wide association study (GWAS) was conducted, and 3,555 Swedish cancer cases and 15,581 controls were analyzed for 226,883 SNPs. The study used haplotype analysis instead of single SNP analysis in order to find putative founder effects. Haplotype association studies identified seven risk loci associated with cancer risk, on chromosomes 1, 7, 11, 14, 16, 17 and 21. Four of the haplotypes, on chromosomes 7, 14, 16 and 17, were confirmed in Swedish familial cancer cases. It was possible to perform exome sequencing in one patient for each of those four loci. No clear disease-causing exonic mutation was found in any of the four loci. Some of the candidate loci hold several cancer genes, suggesting that the risk associated with one locus could involve more than one gene associated with cancer risk. In summary, this study identified seven novel candidate loci associated with cancer risk. It was also suggested that cancer risk at one locus could depend on multiple contributing risk mutations/genes.

Abstract
OBJECTIVE The goal of this study was to investigate the between cluster of differentiation 109 (CD109) expression and tumor diameter, invasion depth, tumor grade, presence of lymph-node metastasis, and overall survival in patients with vulvar squamous cell carcinoma, which is the most common type of vulvar cancer. METHOD Twenty-six patients who underwent an operation for vulvar cancer between 1999 and 2009 in our clinic were included in this study. Immunohistochemical staining was performed on formalin-fixed and paraffin-embedded tissue. RESULT Tumor diameter was not found to be significantly associated with CD109 expression, intensity of cytoplasmic staining, or combined score (P = 0.325, P = 0.169, P = 0.352, respectively). Invasion depth and combined score were also not significantly correlated with CD109 expression (P = 0.324 and P = 0.174 respectively). There was a negative correlation between invasion depth and the intensity of cytoplasmic staining (P = 0.042). There was no significant correlation between tumor stage and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.574, P = 0.389, P = 0.605, respectively). A significant positive correlation was observed between tumor grade and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.003, P = 0.018, P = 0.008, respectively). No significant difference was found between the percentages of CD109 expression in patients with positive (48%) and negative (11%) lymph nodes (P = 0.058). The percentage of CD109 expression did not significantly differ in relation to overall survival (P = 0.483). CONCLUSION Comprehensive and more extensive studies are needed to examine the relationship between CD109 expression and vulvar malignant lesions.

Salivary zinc finger protein 510 peptide as a novel biomarker for detection of oral squamous cell carcinoma in early stages. Clin Chim Acta 2011; 412:1357-65. [PMID: 21497587 DOI: 10.1016/j.cca.2011.04.004] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2011] [Revised: 04/02/2011] [Accepted: 04/04/2011] [Indexed: 11/23/2022]
Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is one of the most frequent malignancies worldwide. Early diagnosis can mean adequate treatment and increase survival. METHODS This study uses ClinProt technique to identify salivary biomarkers for early diagnosis of OSCC. A total of 77 salivary samples from both OSCC patients (n=47) and healthy donors (n=30) were analyzed with MALDI-TOF MS technology. RESULTS Salivary peptides from OSCC patients were separated, using C8-functionalized magnetic beads. Three signals (2918.57 Da, 5592.64 Da, and 4372.66 Da) distinguished OSCC patients from controls. Among them, unique peptide 2918.57 Da, identified as a 24-mer peptide of zinc finger protein 510 (ZNF510), was found in 0% of saliva from healthy individuals, versus 25.0% and 60% from OSCC patients with T1+T2 and T3+T4 stages, respectively (P<0.001). ELISA analysis with rabbit anti-ZNF510 peptide sera shows a starkly higher 24-mer ZNF510 peptide level in saliva from OSCC patients than that in controls (P<0.001). Also, in immunohistochemical analysis of oral tissues, a significantly higher level of ZNF510 was observed in OSCC tissues than in the OSCC free control tissues. Analysis of areas under receiver-operating characteristic (ROC) curves in OSCC early (T1+T2) and late stages (T3+T4) shows greater than 0.95. CONCLUSIONS Identifying 24-mer ZNF510 peptide as OSCC-related salivary biomarkers via proteomic approach proved useful in adjunct diagnosis for early detection rather than specific diagnosis marker for progression of OSCC patients.

Abstract
Background Since the V617F mutation in JAK2 may not be the initiating event in myeloprofilerative disorders (MPDs) we compared molecular changes in neutrophils from patients with polycythemia vera (PV) and essential thrombocythosis (ET), to neutrophils stimulated by G-CSF administration and to normal unstimulated neutrophils Methods A gene expression oligonucleotide microarray with more than 35,000 probes and a microRNA (miR) expression array with 827 probes were used to assess neutrophils from 6 MPD patients; 4 with PV and 2 with ET, 5 healthy subjects and 6 healthy subjects given G-CSF. In addition, neutrophil antigen expression was analyzed by flow cytometry and 64 serum protein levels were analyzed by ELISA. Results Gene expression profiles of neutrophils from the MPD patients were similar but distinct from those of healthy subjects, either unstimulated or G-CSF-mobilized. The differentially expressed genes in MPD neutrophils were more likely to be in pathways involved with inflammation while those of G-CSF-mobilized neutrophils were more likely to belong to metabolic pathways. In MPD neutrophils the expression of CCR1 was increased and that of several NF-κB pathway genes were decreased. MicroRNA miR-133a and miR-1 in MPD neutrophils were down-regulated the most. Levels of 11 serum proteins were increased in MPD patients including MMP-10, MMP-13, VCAM, P-selectin, PDGF-BB and a CCR1 ligand, MIP-1α. Conclusion These studies showed differential expression of genes particularly involved in inflammatory pathways including the NF-κB pathway and down-regulation of miR-133a and miR-1. These two microRNAs have been previous associated with certain cancers as well as the regulation of hyperthrophy of cardiac and skeletal muscle cells. These changes may contribute to the clinical manifestations of the MPDs.
