2. Association with Toxicity and/or Disease at a Transcriptional Level
- CDCA3 transcripts were identified as highly increased in non-small cell lung cancer (NSCLC) versus in nonmalignant patient tissue, with high levels of CDCA3 being associated disease stage, including poor patient prognosis. CDCA3 protein was also increased in NSCLC tissue and expression was limited to tumor cells [PMID: 28487093].
- In patients and in vitro analyses, CDCA3 levels correlate with measures of genome instability and platinum sensitivity, whereby CDCA3high non-small cell lung cancer tumors are sensitive to cisplatin and carboplatin [PMID: 34050247].
- CDCA3 gene expression was upregulated and was significantly higher in lung adenocarcinoma (LUAD) compared with normal tissues. Kaplan-Meier survival curves showed that LUAD samples with higher CDCA3 expression were associated with poorer overall survival (OS) and disease-free survival (DFS). Results of multivariate Cox regression analysis (HR >=1), indicated that CDCA3 can be used as an independent prognostic factor for LUAD. Gene Set Enrichment Analysis (GSEA) suggested that CDCA3 was correlated with DNA-related terms and metabolic-related pathways in LUAD [PMID: 36093552].

- Regulation of mitotic cell cycle: Regulation of mitotic cell cycle currently covers APC/C-mediated degradation of cell cycle proteins [https://reactome.org/PathwayBrowser/#/R-HSA-453276].
- Regulation of NF-kappa B signaling: Nuclear factor kappa B (NF-kappa-B, NF-kappaB) is activated by a diverse range of stimuli including cytokines, ligands of pattern-recognition receptors (PRRs) such as Toll-like receptors (TLRs) in myeloid cells, antigen-activated TCR in T-cells and by DNA damage (reviewed in Yu H et al. 2020; Zhang T et al. 2021). NF-kappa-B regulates the transcription of genes that are involved in immune and inflammatory responses, cell cycle, cell proliferation and apoptosis (Bhatt D & Ghosh S 2014; Liu T et al. 2017; Yu H et al. 2020). In unstimulated cells, NF-kappaB is sequestered in the cytosol through interactions with a class of inhibitor proteins, called NF-kappaB inhibitors (IkBs, such as NFKBIA or NFKBIB) (Jacobs MD & Harrison SC 1998). IkBs mask the nuclear localization signal (NLS) of NF-kappaB preventing its nuclear translocation (Cervantes CF et al. 2011). A key event in NF-kappaB activation involves phosphorylation of IkBs by the I kappaB kinase (IKK) complex which consists of CHUK, IKBKB and IKBKG subunits (Israel A 2010). The activated NF-kappaB signaling is tightly controlled at multiple levels (Dorrington MG & Fraser IDC 2019; Prescott JA et al. 2021). Dysregulated NF-kappaB activity can cause tissue damage associated with inflammatory diseases and is also linked to tumorigenesis (Aggarwal BB & Sung B 2011; Liu T et al.2017; Barnabei L et al. 2021). The regulation of NF-kappaB is cell-type-, context-, and stimulus-dependent and is crucial for orchestrating specific cellular responses (Mussbacher M et al. 2019) [https://reactome.org/PathwayBrowser/#/R-HSA-9758274].

- Entry into mitosis requires the activation of cdk1/cyclin B, while mitotic exit is achieved when the same kinase activity decreases, as cyclin B is degraded. Tome-1 is a cytosolic protein required for proper activation of cdk1/cyclin B and mitotic entry. Tome-1 associates with Skp-1 and is required for degradation of the cdk1 inhibitory tyrosine kinase wee1 to elicit mitotic entry by decreasing wee1 levels, thereby tipping the balance to active cdk1 [PMID: 12679038, PMID: 3032459] .
- Tome-1 mediates the destruction of the mitosis-inhibitory kinase, Wee1, via the E3 ligase, SCF. In turn, Tome-1 itself is targeted for degradation by anaphase-promoting complexes in the G1 phase of the cell cycle [PMID: 15733861].
- CDCA3 depletion causes a defective G2/M-phase cell cycle progression, upregulation of p21 independent of p53, and induction of cellular senescence in non-small cell lung cancer cell lines [PMID: 28487093].
- Suppression of CDCA3 expression with shRNA in oral squamous cell carcinoma derived cell lines significantly inhibited cellular proliferation compared with the control cells by arresting cell-cycle progression at the G1 phase. In addition, there was up-regulation of the cyclin-dependent kinase inhibitors (p21(Cip1), p27(Kip1), p15(INK4B), and p16(INK4A)) [PMID: 22839099].
- Reduced CDCA3 expression resulted in G1/S phase transition arrest, which was attributed to a significant accumulation of p21 in SW480 colorectal cancer cells [PMID: 32107086]; conversely, increased CDCA3 expression promoted G1/S phase transition through decreased p21 accumulation in LoVo cells [PMID: 30226575]. It was also demonstrated that CDCA3 was able to regulate the expression of transcription factor E2F1, thereby repressing p21 expression.
- CDCA3 activated the NF-kappaB/cyclin D1 signaling pathway signaling by interacting with TRAF2 in colorectal cancer cell lines [PMID: 29627567].
- Circular RNA, Circ_0001421, was increased in lung cancer (LC) tissues and cells, and knockdown of circ_0001421 repressed cell proliferation, migration, invasion and glycolysis in vitro. Mechanistically, circ_0001421 could bind to miR-4677-3p, and CDCA3 was a target of miR-4677-3p. Circ_0001421 promoted cell proliferation, migration, invasion and glycolysis in LC by regulating the miR-4677-3p/CDCA3 axis, which providing a new mechanism for LC tumor progression [PMID: 33109222].
- The expression of miRNA-144-5p was found to be significantly down-regulated in TCGA-lung adenocarcinoma (LUAD) dataset, but overexpression of it repressed proliferation and spheroidization, and promoted apoptosis of LUAD cells. miRNA-144-5p was demonstrated to be a validated to target CDCA3 with miRNA-144-5p/CDCA3 mediating the p53 signaling pathway thereby regulating proliferation of LUAD cells [PMID: 36087462].
- A long non-coding RNA, LncCDCA3L, is significantly downregulated in hepatocellular carcinoma and its expression level is associated with tumor size. Mechanistically, lncCDCA3L can repress CDCA3 protein level and inhibit hepatocarcinogenesis by directly binding to CDCA3 mRNA [PMID: 35230745].
The upregulation of C8, specifically CDCA3, in response to lung diseases can be viewed as a cellular adaptation to heightened demands for tissue repair and regeneration [CS: 7]. In a healthy lung exposed to minor injuries or infections, an increase in cell division facilitated by CDCA3 would aid in the rapid repair of damaged tissue, ensuring the maintenance of lung function and integrity [CS: 6]. This increased mitotic activity, driven by CDCA3's role in promoting the transition from the G2 phase to mitosis, would be a crucial response to restore normal lung architecture and function after injury or infection [CS: 7].
In the context of lung diseases like NSCLC, however, this adaptive response becomes maladaptive [CS: 6]. CDCA3 is highly increased in NSCLC compared to nonmalignant tissue, and its overexpression is associated with worse patient prognosis [CS: 8]. This overexpression may be a response to the cellular need for increased mitosis in the rapidly dividing cancer cells [CS: 5]. CDCA3, by participating in E3 ligase complexes, mediates the ubiquitination and degradation of WEE1 kinase at the G2/M phase, thereby promoting cell division [CS: 7].
- Downregulation of OY-TES-1 by RNAi resulted in significant changes in expression of NANOG, CD9, CCND2 and CDCA3 in the liver cancer cell line BEL-7404. NANOG, CD9, CCND2 and CDCA3 may be involved in cell proliferation, migration, invasion and apoptosis, yet also may be functionally related to each other and OY-TES-1 [PMID: 25673160].
- HomeoboxB3 (HoxB3) mRNA and protein are overexpressed in primary prostate cancer tissues compared to the adjacent normal prostate tissues and its overexpression is associated with higher Gleason grade clinical stage. Kaplan and Meier analysis showed that HoxB3 overexpression predicts poor survival outcome in prostate cancer. Overexpression of HoxB3 was also shown to promote LNCaP cell proliferation and migration in vitro. Depletion of HoxB3 in PC-3 cells decreased the capacity of proliferation in a cell division cycle associated 3 (CDCA3)-dependent manner both in vitro and in vivo. ChIP analysis indicated that HoxB3 can bind to the CDCA3 promoter region and transactivate the CDCA3 expression [PMID: 23219899].
- MYBL2 was elevated in bladder cancer (BLCA) tissues and significantly correlated with clinicopathological parameters and cancer-specific survival in BLCA patients. Phenotypic assays showed that MYBL2 deficiency suppressed the proliferation and migration of BLCA cells in vitro and in vivo, whereas MYBL2 overexpression contributed to the opposite phenotype. Mechanistically, MYBL2 could bind to the promoter of its downstream target gene cell division cycle-associated protein 3 (CDCA3) and transactivate it, which in turn promoted the malignant phenotype of BLCA cells. Further investigations revealed that MYBL2 interacted with forkhead box M1 (FOXM1) to co-regulate the transcription of CDCA3 [PMID: 36071275].
- CDH1: In non-small cell lung cancer (NSCLC) cells, CDCA3 protein levels are regulated by the ubiquitin ligase APC/C and cofactor Cdh1. Results showed that the degradation of CDCA3 is modulated by activity of casein kinase 2 (CK2) which promotes an interaction between CDCA3 and Cdh1 [PMID: 34050247].
- CDCA3 was identified as part of the miR-375-HOXB3-CDCA3/DNMT3B regulatory circuitry which contributes to leukemogenesis, where knockdown of HOXB3 was shown to reduce the expression of CDCA3 leading to decreased cell proliferation [PMID: 29439669].
- Survival analysis of hub genes suggested that lower expression of genes such as CDCA3 was associated with better overall survival of bladder cancer patients [PMID: 29234286].
- CDCA3, CDCA5, and CDCA8 mRNA expression levels were significantly higher than the control sample in both clinical breast tumor samples and cancer cell lines while also being associated with reduced patient survival [PMID: 29467944].
- CDCA3 expression was increased in human gastric cancer tissues compared with those in adjacent non-tumor tissues. CDCA3 may be a potential prognostic marker that promotes cell proliferation in gastric cancer [PMID: 30816466].
- RNA expression of CDCA2, CDCA3, CDCA5 and CDCA8 were found to be up-regulated in hepatocellular carcinoma (HCC) tissues, and these genes were associated with poor overall survival and relapse free survival except CDCA7 [PMID: 32913466]. Gene expression data from three independent hepatocellular carcinoma (HCC) cohorts was used to demonstrate prognostic significance of KIF18B and CDCA3 as predictors of patient survival outcomes [PMID: 25236463].
- The CDCA3 expression at both the mRNA and protein levels was frequently up-regulated in all oral squamous cell carcinoma derived cell lines examined and primary tumors compared to normal controls. Among the clinical variables analyzed, the CDCA3 expression status was closely related to tumor size [PMID: 22839099].
- In colorectal cancer (CRC) patient tissue samples, CDCA3 expression was significantly associated with tumor progression and poor survival. Overexpression of CDCA3 increased proliferation in LoVo CRC cells, whereas CDCA3 knockdown in SW480 CRC cells led to decreased proliferation, in vitro and in vivo [PMID: 30226575].
- Human colorectal tumor specimens significantly expressed more CDCA3 than non-cancer tissues. In addition, CDCA3 promoted colorectal cancer cell proliferation in vitro [PMID: 29627567].
- CDCA3 expression was increased in prostate cancer (PCa) patient samples, and patients with higher CDCA3 expression had poor outcomes. High CDCA3 expression was positively correlated with advanced T stage, N stage, Gleason score, and served as an independent predictor of progress free interval in PCa patients. [PMID: 37682152].
