Abstract
Nucleus accumbens-associated protein 1 (NACC1) is a member of the broad complex, tramtrack, bric-a-brac/poxvirus and zinc finger (BTB/POZ) protein families, mainly exerting its biological functions as a transcription co-regulator. NACC1 forms homo- or hetero-dimers through the BTB/POZ or BANP, E5R, and NACC1 (BEN) domain with other transcriptional regulators to regulate downstream signals. Recently, the overexpression of NACC1 has been observed in various tumors and is positively associated with tumor progression, high recurrence rate, indicating poor prognosis. NACC1 also regulates biological processes such as embryonic development, stem cell pluripotency, innate immunity, and related diseases. Our review combines recent research to summarize advancements in the structure, biological functions, and relative molecular mechanisms of NACC1. The future development of NACC1 clinical appliances is also discussed.

[PMID: 36568940 PMCID: PMC9782620 DOI: 10.4251/wjgo.v14.i12.2329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 10/16/2022] [Accepted: 11/22/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Nucleus accumbens-1 (NAC-1) is highly expressed in a variety of tumors, including colon cancer, and is closely associated with tumor recurrence, metastasis, and invasion.
AIM To determine whether and how NAC-1 affects antitumor immunity in colon cancer.
METHODS NAC-1-siRNA was transfected into RKO colon cancer cells to knock down NAC expression; tumor cells with or without knockdown of NAC-1 were treated with CD8+ T cells to test their cytocidal effect. The level of the immune checkpoint programmed death receptor-1 ligand (PD-L1) in colon cancer cells with or without knockdown of NAC-1 was analyzed using Quantitative real-time polymerase chain reaction and Western blotting. A double luciferase reporter assay was used to examine the effects of NAC-1 on the transcription of PD-L1. Mice bearing MC-38-OVA colon cancer cells expressing NAC-shRNA or control-shRNA were treated with OT-I mouse CD8+ T cells to determine the tumor response to immunotherapy. Immune cells in the tumor tissues were analyzed using flow cytometry. NAC-1, PD-L1 and CD8+ T cells in colon cancer specimens from patients were examined using immunohistochemistry staining.
RESULTS Knockdown of NAC-1 expression in colon cancer cells significantly enhanced the cytocidal effect of CD8+ T cells in cell culture experiments. The sensitizing effect of NAC-1 knockdown on the antitumor action of cytotoxic CD8+ T cells was recapitulated in a colon cancer xenograft animal model. Furthermore, knockdown of NAC-1 in colon cancer cells decreased the expression of PD-L1 at both the mRNA and protein levels, and this effect could be rescued by transfection of an RNAi-resistant NAC-1 expression plasmid. In a reporter gene assay, transient expression of NAC-1 in colon cancer cells increased the promoter activity of PD-L1, indicating that NAC-1 regulates PD-L1 expression at the transcriptional level. In addition, depletion of tumoral NAC-1 increased the number of CD8+ T cells but decreased the number of suppressive myeloid-derived suppressor cells and regulatory T cells.
CONCLUSION Tumor expression of NAC-1 is a negative determinant of immunotherapy.

Abstract
Previous studies have demonstrated that calpain small subunit 4 (Capn4) is able to regulate the viability and metastasis of cancer cells. However, the regulatory effects and underlying molecular mechanism of Capn4 in ovarian carcinoma cells are not well understood. The purpose of the present study was to investigate the role of Capn4 in ovarian carcinoma cells and analyze the possible mechanism mediated by Capn4. The expression levels of Capn4 and osteopontin (OPN) were determined and the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway was analyzed in ovarian carcinoma cells. The results of the present study revealed that Capn4 and OPN were overexpressed in clinical ovarian carcinoma tissues and ovarian carcinoma cells. Capn4 silencing downregulated OPN expression, and suppressed ovarian carcinoma cell viability and migration. Capn4 silencing enhanced apoptosis of ovarian carcinoma cells by increasing activity of the capase-3 apoptosis signaling pathway. Capn4 promoted the metastasis of ovarian carcinoma cells by interacting with the PI3K/AKT signaling pathway via upregulation of OPN expression. In conclusion, the results of the present study indicate that Capn4 may be a potential therapeutic target for the treatment of ovarian carcinoma.

Loss of beclin 1 expression in ovarian cancer: A potential biomarker for predicting unfavorable outcomes. Oncol Lett 2017; 15:1170-1176.

Abstract
The clinicopathological significance and prognostic value of the expression of proteins associated with autophagy, beclin 1 (BECN1), 1A/1B-light chain 3 (LC3) and high mobility group box-1 protein (HMGB-1), were investigated in patients with ovarian carcinoma, receiving combination chemotherapy with a platinum agent and a taxane. Immunohistochemical staining was performed for autophagy-associated proteins in tumor tissues from 141 patients with ovarian carcinoma. Clinical data were collected retrospectively by reviewing medical charts, and the association between protein expression, clinicopathological features and survival was investigated. Amongst 141 ovarian carcinoma samples, the loss of BECN1, LC3, and HMGB-1 expression was identified in 59 (41.8%), 35 (24.8%), and 66 (46.8%) samples, respectively. Clinicopathological factors were not significantly associated with the loss of BECN1 expression. However, significant associations were demonstrated between the expression of BECN1, LC3, and HMGB-1. In addition, loss of BECN1 expression demonstrated a significant association with poor progression-free and poor overall survival. Multivariate analysis demonstrated that loss of BECN1 expression and postoperative residual tumor were significant independent predictors of poor progression-free survival and poor overall survival. These results indicated that loss of BECN1 expression in ovarian carcinoma is a negative prognosticator in patients receiving platinum-based chemotherapy. Assessment of BECN1 expression may be useful for predicting an unfavorable response to platinum-based chemotherapy in ovarian carcinoma.

Abstract
This study aimed to explore the role of miR-339-5p in ovarian cancer. The expression of miR-339-5p in seven ovarian cancer cell lines (Hey, SKOV3, OVCAR5, SKOV3-IP, A2780, CAOV3, and OVCA433) was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The miR-339-5p mimic and inhibitor were used to regulate its expression. Migration, invasion, and proliferation were examined. A bioinformatics analysis was used to predict targets, and a dual-luciferase reporter system was applied for validation, along with Western blot verification. Additionally, the association of miR-339-5p and its target genes with ovarian cancer was analyzed based on The Cancer Genome Atlas (TCGA) database. OVCAR5 and SKOV3 had the highest and lowest miR-339-5p expression, respectively. Inhibition of miR-339-5p expression increased the migration and invasion of OVCAR5 cells, while in SKOV3 cells, upregulated miR-339-5p attenuated the migration and invasion ability. Modulation of miR-339-5p had no effect on proliferation. The genes nucleus accumbens associated 1(BEN and BTB (POZ) domain containing) (NACC1) and B cell lymphoma-6 (bcl6) were validated to be targets of miR-339-5p. Clinically, patients with a high expression of NACC1 had a high risk in the survival analysis. miR-339-5p inhibits migration and invasion in ovarian cancer by targeting NACC1 and BCL6. miR-339-5p may be a biomarker of metastasis in ovarian cancer; NACC1 had a predictive value for ovarian cancer progression.

Abstract
Ovarian cancer is the most lethal gynecologic malignancy. Despite advances in chemotherapy, the five-year survival rate of advanced ovarian cancer patients with peritoneal metastasis remains around 30%. The most significant prognostic factor is stage, and most patients present at an advanced stage with peritoneal dissemination. There is often no clearly identifiable precursor lesion; therefore, the events leading to metastatic disease are poorly understood. This article reviews metastatic suppressor genes, the epithelial-mesenchymal transition (EMT), and the tumor microenvironment as they relate to ovarian cancer metastasis. Additionally, novel chemotherapeutic agents targeting the metastasis-related biochemical pathways are discussed.
