Abstract
BACKGROUND Nuclear pore complexes (NPCs) are sophisticated and dynamic protein structures that straddle the nuclear envelope and act as gatekeepers for transporting molecules between the nucleus and the cytoplasm. NPCs comprise up to 30 different proteins known as nucleoporins (NUPs). However, a growing body of research has suggested that NPCs play important roles in gene regulation, viral infections, cancer, mitosis, genetic diseases, kidney diseases, immune system diseases, and degenerative neurological and muscular pathologies. PURPOSE In this review, we introduce the structure and function of NPCs. Then We described the physiological and pathological effects of each component of NPCs which provide a direction for future clinical applications. METHODS The literatures from PubMed have been reviewed for this article. CONCLUSION This review summarizes current studies on the implications of NPCs in human physiology and pathology, highlighting the mechanistic underpinnings of NPC-associated diseases.

Yu Y, Farooq MS, Eberhart Meessen S, Jiang Y, Kato D, Zhan T, Weiss C, Seger R, Kang W, Zhang X, Yu J, Ebert MPA, Burgermeister E. Nuclear pore protein POM121 regulates subcellular localization and transcriptional activity of PPARγ. Cell Death Dis 2024; 15:7. [PMID: 38177114 PMCID: PMC10766976 DOI: 10.1038/s41419-023-06371-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 11/30/2023] [Accepted: 12/05/2023] [Indexed: 01/06/2024]
Abstract
Manipulation of the subcellular localization of transcription factors by preventing their shuttling via the nuclear pore complex (NPC) emerges as a novel therapeutic strategy against cancer. One transmembrane component of the NPC is POM121, encoded by a tandem gene locus POM121A/C on chromosome 7. Overexpression of POM121 is associated with metabolic diseases (e.g., diabetes) and unfavorable clinical outcome in patients with colorectal cancer (CRC). Peroxisome proliferator-activated receptor-gamma (PPARγ) is a transcription factor with anti-diabetic and anti-tumoral efficacy. It is inhibited by export from the nucleus to the cytosol via the RAS-RAF-MEK1/2-ERK1/2 signaling pathway, a major oncogenic driver of CRC. We therefore hypothesized that POM121 participates in the transport of PPARγ across the NPC to regulate its transcriptional activity on genes involved in metabolic and tumor control. We found that POM121A/C mRNA was enriched and POM121 protein co-expressed with PPARγ in tissues from CRC patients conferring poor prognosis. Its interactome was predicted to include proteins responsible for tumor metabolism and immunity, and in-silico modeling provided insights into potential 3D structures of POM121. A peptide region downstream of the nuclear localization sequence (NLS) of POM121 was identified as a cytoplasmic interactor of PPARγ. POM121 positivity correlated with the cytoplasmic localization of PPARγ in patients with KRAS mutant CRC. In contrast, POM121A/C silencing by CRISPR/Cas9 sgRNA or siRNA enforced nuclear accumulation of PPARγ and activated PPARγ target genes promoting lipid metabolism and cell cycle arrest resulting in reduced proliferation of human CRC cells. Our data suggest the POM121-PPARγ axis as a potential drugable target in CRC.

Abstract
The mechanism of human immunodeficiency virus 1 (HIV-1) nuclear entry, required for productive infection, is not fully understood. Here, we report that in HeLa cells and activated CD4+ T cells infected with HIV-1 pseudotyped with VSV-G and native Env protein, respectively, Rab7+ late endosomes containing endocytosed HIV-1 promote the formation of nuclear envelope invaginations (NEIs) by a molecular mechanism involving the VOR complex, composed of the outer nuclear membrane protein VAP-A, hyperphosphorylated ORP3 and Rab7. Silencing VAP-A or ORP3 and drug-mediated impairment of Rab7 binding to ORP3-VAP-A inhibited the nuclear transfer of the HIV-1 components and productive infection. In HIV-1-resistant quiescent CD4+ T cells, ORP3 was not hyperphosphorylated and neither VOR complex nor NEIs were formed. This new cellular pathway and its molecular players are potential therapeutic targets, perhaps shared by other viruses that require nuclear entry to complete their life cycle.

Modeling HIV-1 nuclear entry with nucleoporin-gated DNA-origami channels. Nat Struct Mol Biol 2023; 30:425-435.

Abstract
Delivering the virus genome into the host nucleus through the nuclear pore complex (NPC) is pivotal in human immunodeficiency virus 1 (HIV-1) infection. The mechanism of this process remains mysterious owing to the NPC complexity and the labyrinth of molecular interactions involved. Here we built a suite of NPC mimics-DNA-origami-corralled nucleoporins with programmable arrangements-to model HIV-1 nuclear entry. Using this system, we determined that multiple cytoplasm-facing Nup358 molecules provide avid binding for capsid docking to the NPC. The nucleoplasm-facing Nup153 preferentially attaches to high-curvature regions of the capsid, positioning it for tip-leading NPC insertion. Differential capsid binding strengths of Nup358 and Nup153 constitute an affinity gradient that drives capsid penetration. Nup62 in the NPC central channel forms a barrier that viruses must overcome during nuclear import. Our study thus provides a wealth of mechanistic insight and a transformative toolset for elucidating how viruses like HIV-1 enter the nucleus.

Tough Way In, Tough Way Out: The Complex Interplay of Host and Viral Factors in Nucleocytoplasmic Trafficking during HIV-1 Infection. Viruses 2022; 14:v14112503.

Abstract
Human immunodeficiency virus-1 (HIV-1) is a retrovirus that integrates its reverse-transcribed genome as proviral DNA into the host genome to establish a successful infection. The viral genome integration requires safeguarding the subviral complexes, reverse transcription complex (RTC) and preintegration complex (PIC), in the cytosol from degradation, presumably effectively secured by the capsid surrounding these complexes. An intact capsid, however, is a large structure, which raises concerns about its translocation from cytoplasm to nucleus crossing the nuclear membrane, guarded by complex nuclear pore structures, which do not allow non-specific transport of large molecules. In addition, the generation of new virions requires the export of incompletely processed viral RNA from the nucleus to the cytoplasm, an event conventionally not permitted through mammalian nuclear membranes. HIV-1 has evolved multiple mechanisms involving redundant host pathways by liaison with the cell's nucleocytoplasmic trafficking system, failure of which would lead to the collapse of the infection cycle. This review aims to assemble the current developments in temporal and spatial events governing nucleocytoplasmic transport of HIV-1 factors. Discoveries are anticipated to serve as the foundation for devising host-directed therapies involving selective abolishment of the critical interactomes between viral proteins and their host equivalents.

Abstract
For human immunodeficiency virus 1 (HIV-1) to infect non-dividing cells, pre-integration complex (PIC) must be transported into the nucleus within the replication cycle. We previously reported that the karyopherin β1 (KPNB1)-nucleoporin Pom121 pathway, related to the downstream process of PIC nuclear import, mediates efficient HIV-1 PIC nuclear import. Further, our earlier RNA transcriptome sequencing revealed that karyopherin α2 (KPNA2) was among the differentially expressed importin family members during monocyte to macrophage differentiation. Although PIC transport into the nucleus in HIV-1 has been widely studied, much remains to be understood about it. In this study, we confirmed our previous RNA sequencing results and found that HIV-1 replication was significantly lower in 293T cells with siRNA-mediated KPNA2 knockdown and higher in KPNA2-upregulated cells. Quantitative PCR indicated that viral replication was impaired during cDNA nuclear import. The N-terminal of the capsid protein p24 interacted with KPNA2, and KPNB1 participated in KPNA2-mediated PIC nuclear import. Disruption of the capsid-KPNA2 binding by overexpression of full-length p24 or p24 N-terminal impaired the PIC nuclear import. These results indicate that KPNA2 is an important upstream adaptor of the KPNB1-Pom121 axis, thereby mediating HIV-1 PIC nuclear transportation. KPNA2 is thus a potential target for HIV-1 antiviral treatment.

Abstract
BACKGROUND Nuclear pore membrane protein 121 (POM121) is a novel biomarker involved in tumorigenesis and metastasis. However, little is known about the role of POM121 in non-small-cell lung cancer (NSCLC). OBJECTIVE The aim of this study was to detect the expression of POM121 in NSCLC and its relationship with clinicopathologic feature and cell biological behavior, and explore the underlying mechanisms. METHODS The expression of POM121 in NSCLC tissues and para-carcinoma tissues was compared by quantitative real-time PCR and immunohistochemistry analysis. The relationship between POM121 protein and clinicopathological characteristics in NSCLC was investigated. Roles of POM121 in NSCLC cells were investigated by CCK-8 assay, clone formation assay, transwell migration and invasion assay, and in vivo experiments. Variations of signaling pathways were determined by qRT-PCR and Western blot. RESULTS The POM121 expression in NSCLC tissues was significantly higher than that in para-carcinoma tissues, both at the mRNA and protein level. The POM121 expression was related to sex, advanced differentiation, tumor diameter, lymph node metastases, distant metastases, American Joint Committee on Cancer (AJCC) stage, venous invasion, and perineural invasion in NSCLC. Kaplan-Meier analysis indicated that NSCLC patients with high POM121 expression had poor overall survival. Downregulation of POM121 inhibited cell proliferation, clone formation, migration and invasion. TGF-β/SMAD and PI3K/AKT pathways were involved in POM121-induced functional changes in NSCLC cells. CONCLUSION POM121 plays an oncogenic role in NSCLC through TGF-β/SMAD and PI3K/AKT pathways. POM121 expression is a potential independent prognostic factor for NSCLC.

Abstract
Esophageal cancer (ESCA) is a leading cause of cancer-related mortality, with poor prognosis worldwide. DNA damage repair is one of the hallmarks of cancer. Loss of genomic integrity owing to inactivation of DNA repair genes can increase the risk of cancer progression and lead to poor prognosis. We aimed to identify a novel gene signature related to DNA repair to predict the prognosis of ESCA patients. Based on gene expression profiles of ESCA patients from The Cancer Genome Atlas and gene set enrichment analysis, 102 genes related to DNA repair were identified as candidates. After stepwise Cox regression analysis, we established a five-gene prognostic model comprising DGCR8, POM121, TAF9, UPF3B, and BCAP31. Kaplan-Meier survival analysis confirmed a strong correlation between the prognostic model and survival. Moreover, we verified the clinical value of the prognostic signature under the influence of different clinical parameters. We found that small-molecule drugs (trametinib, selumetinib, and refametinib) could help to improve patient survival. In summary, our study provides a novel and promising prognostic signature based on DNA-repair-related genes to predict survival of patients with ESCA. Systematic data mining provides a theoretical basis for further exploring the molecular pathogenesis of ESCA and identifying therapeutic targets.

Abstract
Aims: The aim of this study was to examine the RNA and protein expression levels and clinical significance of the pore membrane protein 121 kDa (POM121) in lung cancer. Materials and Methods: Paired lung cancer and adjacent nontumor tissues were obtained from lung cancer patients to measure the expression of POM121 by quantitative reverse transcription-polymerase chain reaction and immunohistochemistry. Patient clinical and pathological data were collected to analyze their relationships with POM121 protein expression levels by chi-square test and log-rank test, respectively. Results: POM121 mRNA and protein expression were both upregulated in lung cancer tissues. POM121 protein expression was observed in 48.00% (36/75) of lung cancer tissues and 25.33% (19/75) of adjacent nontumor tissues. A chi-square analysis indicated that this difference was statistically significant (p < 0.05). Furthermore, we found that POM121 protein expression was correlated with gender, tumor node metastasis stage, and lymphatic metastasis (p < 0.05). In addition, we found a significant relationship among POM121 expression, gender, and metastasis based on a multivariate logistic regression analysis. A Kaplan-Meier survival analysis indicated that lung cancer patients with POM121 expression had a poorer prognosis than those without POM121 expression (p < 0.05). Conclusion: POM121 protein expression is associated with lung cancer metastasis and is a potential prognostic biomarker for lung cancer patients.

Abstract
The nuclear pore membrane protein 121 (POM121) is an important member of the nuclear pore complex which regulates nucleocytoplasmic transport, but little is known about the role of POM121 in laryngeal cancer. In this study, quantitative real-time polymerase chain reaction and immunohistochemistry were performed to detect POM121 expression in laryngeal tissues. The associations between POM121 and clinicopathological characteristics and overall survival in laryngocarcinoma patients were also analyzed. The mechanism of POM121 was preliminarily explored through gene set enrichment analysis (GSEA). mRNA and protein expression of POM121 in laryngocarcinoma tissues were higher than those in nontumor tissues. High POM121 expression was positively correlated with poor differentiation (χ²=42.391, P<0.001), advanced distant metastases (χ²=20.346, P<0.001) and TNM stage (χ²=23.436, P<0.001). Laryngocarcinoma patients with high POM121 level tended to have poor overall survival. GSEA confirmed that the mechanism of POM121 in laryngeal cancer may relate to sphingolipid metabolism, lysosome, fatty acid metabolism, ribosome, nucleotide excision repair and the PPAR signaling pathway. Overall, POM121 expression might be a prognostic biomarker in laryngeal cancer, and POM121 has the potential to present as a therapeutic target for laryngocarcinoma patients.

Abstract
Background: Nuclear pore membrane protein 121 (POM121) plays a crucial role in nucleocytoplasmic transport, but its significance in tumorigenesis and the progression of colorectal cancer (CRC) remains unknown. The aim of this study was to evaluate the relationship between POM121 and CRC.Methods: POM121 expression in colorectal tissues was analyzed at both the gene and protein levels. We investigated the connection between POM121 expression and clinicopathological features, as well as overall survival. A gene set enrichment analysis (GSEA) was performed, and a protein-protein interaction (PPI) network was constructed to determine the mechanism of POM121 in CRC.Results: CRC tissues displayed a striking increase in POM121 expression compared with colonitis and pericarcinomatous mucosa tissues (66.61% vs 24.36% vs 24.11%, respectively, p < 0.0167). POM121 overexpression was significantly associated with lymph node metastasis, distant metastasis, TNM stage, venous invasion, perineural invasion, preoperative CEA and CA19-9 levels, and Ki67 expression. CRC patients with high POM121 levels tended to have poor overall survival rates. POM121 may participate in the regulation of the cell cycle and DNA repair in CRC.Conclusions: Our results suggest that POM121 has the potential to serve as a novel prognostic biomarker in CRC patients.

Abstract
Background: The aim of this study was to confirm the role of nuclear pore membrane protein 121(POM121) in oral squamous cell carcinoma and to explore the underlying mechanism. Methods: POM121mRNA and protein expressions were evaluated in OSCC tissues and normal oral tissues by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry. The relationship between POM121 expression and clinical characteristics was analyzed. Bioinformatics analysis was performed to explore the possible mechanisms how POM121 affected OSCC. Results: We confirmed that POM121 mRNA expression in OSCC tissues was significantly higher than that in non-tumorous tissues, as was POM121 protein expression. POM121 expression was associated with distant metastasis and TNM stage. Multivariate analysis confirmed POM121 expression as an independent prognostic factor for OSCC patients. OSCC patients with high POM121 expression had a worse overall survival (OS) compared with patients with low POM121 expression. Bioinformatics analysis indicated POM121 may regulate OSCC through hedgehog and /or p53 signaling pathway. Conclusion: Targeting of POM121 expression levels could provide new diagnostic and therapeutic strategies for OSCC patients.
