Abstract
Over the past decade, the role of the 14-3-3 protein has received increasing interest. Seven subtypes of 14-3-3 proteins exhibit high homology; however, each subtype maintains its specificity. The 14-3-3ε protein is involved in various physiological processes, including signal transduction, cell proliferation, apoptosis, autophagy, cell cycle regulation, repolarization of cardiac action, cardiac development, intracellular electrolyte homeostasis, neurodevelopment, and innate immunity. It also plays a significant role in the development and progression of various diseases, such as cardiovascular diseases, inflammatory diseases, neurodegenerative disorders, and cancer. These immense and various involvements of 14-3-3ε in diverse processes makes it a promising target for drug development. Although extensive research has been conducted on 14-3-3 dimers, studies on 14-3-3 monomers are limited. This review aimed to provide an overview of recent reports on the molecular mechanisms involved in the regulation of binding partners by 14-3-3ε, focusing on issues that could help advance the frontiers of this field.

Integrative Role of 14-3-3ε in Sleep Regulation. Int J Mol Sci 2021; 22:ijms22189748. [PMID: 34575915 PMCID: PMC8467329 DOI: 10.3390/ijms22189748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 08/30/2021] [Accepted: 09/02/2021] [Indexed: 11/21/2022] Open
Abstract
Sleep is a crucial factor for health and survival in all animals. In this study, we found by proteomic analysis that some cancer related proteins were impacted by the circadian clock. The 14-3-3ε protein, expression of which is activated by the circadian transcription factor Clock, regulates adult sleep of Drosophila independent of circadian rhythm. Detailed analysis of the sleep regulatory mechanism shows that 14-3-3ε directly targets the Ultrabithorax (Ubx) gene to activate transcription of the pigment dispersing factor (PDF). The dopamine receptor (Dop1R1) and the octopamine receptor (Oamb), are also involved in the 14-3-3ε pathway, which in 14-3-3ε mutant flies causes increases in the dopR1 and OAMB, while downregulation of the DopR1 and Oamb can restore the sleep phenotype caused by the 14-3-3ε mutation. In conclusion, 14-3-3ε is necessary for sleep regulation in Drosophila.

Abstract
Cancer progression is dependent on heightened mechanical adaptation, both for the cells' ability to change shape and to interact with varying mechanical environments. This type of adaptation is dependent on mechanoresponsive proteins that sense and respond to mechanical stress, as well as their regulators. Mechanoresponsive proteins are part of the mechanobiome, which is the larger network that constitutes the cell's mechanical systems that are also highly integrated with many other cellular systems, such as gene expression, metabolism, and signaling. Despite the altered expression patterns of key mechanobiome proteins across many different cancer types, pharmaceutical targeting of these proteins has been overlooked. Here, we review the biochemistry of key mechanoresponsive proteins, specifically nonmuscle myosin II, α-actinins, and filamins, as well as the partnering proteins 14-3-3 and CLP36. We also examined a wide range of data sets to assess how gene and protein expression levels of these proteins are altered across many different cancer types. Finally, we determined the potential of targeting these proteins to mitigate invasion or metastasis and suggest that the mechanobiome is a goldmine of opportunity for anticancer drug discovery and development.

Arch Biochem Biophys 2018; 663:101-108. [PMID: 30550728 DOI: 10.1016/j.abb.2018.12.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 12/04/2018] [Accepted: 12/10/2018] [Indexed: 10/27/2022]
Abstract
Nuclear factor 45 (NF-45) has been found to be markedly upregulated in several cancers, including esophageal squamous cell carcinoma (ESCC). However, the molecular mechanisms underlying its functions remain unclear. In this study, we confirm that overexpression of NF45 was frequently detected in ESCC tissues and was associated with poor outcome. Overexpression studies revealed that NF-45 promoted cell growth and invasion and upregulated Rac1/Tiam1 signalling via 14-3-3ε protein in ESCC cell lines. This novel mechanism linking upregulated NF45 expression to increased 14-3-3ε/Rac1/Tiam1 signalling and subsequent growth and invasion in ESCC may aid in identification of new therapeutic targets for this disease.

Abstract
AIM: To investigate the correlation between YWHAE overexpression and colon cancer proliferation.
METHODS: We conducted immunohistochemical analysis of YWHAE overexpression in 87 colon carcinoma specimens and analyzed its relationship with clinical and pathological parameters. YWHAE expression was then silenced by RNA interference in colon cancer cell line HT-29, and the expression levels of YWHAE protein and mRNA were assayed by Western blot and reverse transcription-PCR, respectively. Cell proliferation was evaluated using the MTT method, and cell cycle and apoptosis were examined by flow cytometry. Colony formation assay was used to determine the growth properties of transfected cells.
RESULTS: YWHAE was highly expressed in colon carcinoma, and negative or low expression was observed in colon mucosal epithelial cells (P < 0.001). The expression intensity of YWHAE was significantly higher in colon cancer with metastasis than in colon cancer without metastasis (P < 0.05). The proliferation and colony formation ability of colon cancer cells were significantly reduced after silencing of YWHAE expression. Additional results showed that reduced YWHAE expression in colon cells led to an increased cell apoptosis rate and cell cycle G1 arrest.
CONCLUSION: YWHAE is overexpressed in colon cancer, which may be related to metastasis in colon carcinoma. Silencing of YWHAE inhibited the proliferation ability of colon cancer cells, which may be associated with cell apoptosis and cell cycle arrest.

Abstract
BACKGROUND Colorectal cancer (CRC), a heterogeneous disease that is common in both men and women, continues to be one of the predominant cancers worldwide. Lifestyle, diet, environmental factors and gene defects all contribute towards CRC development risk. Therefore, the identification of novel biomarkers to aid in the management of CRC is crucial. The aim of the present study was to identify candidate biomarkers for CRC, and to develop a better understanding of their role in tumourogenesis. METHODS In this study, both plasma and tissue samples from patients diagnosed with CRC, together with non-malignant and normal controls were examined using mass spectrometry based proteomics and metabolomics approaches. RESULTS It was established that the level of several biomolecules, including serotonin, gamma enolase, pyruvate kinase and members of the 14-3-3 family of proteins, showed statistically significant changes when comparing malignant versus non-malignant patient samples, with a distinct pattern emerging mirroring cancer cell energy production. CONCLUSION The diagnosis and management of CRC could be enhanced by the discovery and validation of new candidate biomarkers, as found in this study, aimed at facilitating early detection and/or patient stratification together with providing information on the complex behaviour of cancer cells.

Abstract
This study was designed to explore the correlation between expressions of SATB1 and S100A4 and their relationships to the clinicopathologic parameters of colorectal carcinoma (CRC). Expressions of SATB1 and S100A4 were evaluated by immunohistochemistry in a cohort of 131 primary CRC patients undergone surgical resection from 2005 to 2007. SATB1 and S100A4 were positively expressed in 48.9% and 54.2% of CRC cases, respectively. SATB1 and S100A4 expressions in tumor tissues were significantly higher than those in the corresponding normal tissues. A positive correlation was observed between SATB1 and S100A4. Moreover, the levels of SATB1 and S100A4 were both significantly associated with invasion, lymph node status, and TNM stage of CRC, whereas S100A4 expression was also correlated with distant metastasis. Multivariate analysis revealed that SATB1 expression was an independent prognostic indicator for poor survival of CRC. Further survival analysis indicated that co-expression of SATB1 and S100A4 suggested a worse 5-year overall survival rate in CRC patients. Thus, combined analysis of SATB1 and S100A4 expressions may be valuable in determining the development and progression of CRC. Co-expression of SATB1 and S100A4 is an unfavorable prognostic indicator and may be useful in the follow-up of patients with CRC.

Chemokine CXCL14 is associated with prognosis in patients with colorectal carcinoma after curative resection. J Transl Med 2013; 11:6. [PMID: 23294544 PMCID: PMC3551837 DOI: 10.1186/1479-5876-11-6] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2012] [Accepted: 12/21/2012] [Indexed: 02/05/2023] Open
Abstract
Background The chemokine CXCL14 has been reported to play an important role in the progression of many malignancies such as breast cancer and papillary thyroid carcinoma, but the role of CXCL14 in colorectal carcinoma (CRC) remains to be established. The purpose of this study was to investigate the expression pattern and significance of CXCL14 in CRC progression. Method 265 colorectal carcinoma specimens and 129 matched adjacent normal colorectal mucosa specimens were collected. Expression of CXCL14 in clinical samples was examined by immunostaining. The effect of CXCL14 on colorectal carcinoma cell proliferation was measured by MTT assay, BrdU incorporation assay and colony formation assay. The impact of CXCL14 on migration and invasion of colorectal carcinoma cells was determined by transwell assay and Matrigel invasion assay, respectively. Results CXCL14 expression was significantly up-regulated in tumor tissues compared with adjacent nontumorous mucosa tissues (P < 0.001). Tumoral CXCL14 expression levels were significantly correlated with TNM (Tumor-node-metastasis) stage, histodifferentiation, and tumor size. In multivariate Cox regression analysis, high CXCL14 expression in tumor specimens (n = 91) from stage I/II patients was associated with increased risk for disease recurrence (risk ratio, 2.92; 95% CI, 1.15-7.40; P = 0.024). Elevated CXCL14 expression in tumor specimens (n = 135) from stage III/IV patients correlated with worse overall survival (risk ratio, 3.087; 95% CI, 1.866-5.107; P < 0.001). Functional studies demonstrated that enforced expression of CXCL14 in SW620 colorectal carcinoma cells resulted in more aggressive phenotypes. In contrast, knockdown of CXCL14 expression could mitigate the proliferative, migratory and invasive potential of HCT116 colorectal carcinoma cells. Conclusion Taken together, CXCL14 might be a potential novel prognostic factor to predict the disease recurrence and overall survival and could be a potential target of postoperative adjuvant therapy in CRC patients.
